Driving and driving safety systems

Driving systems and your responsibility
Your vehicle is equipped with driving systems which assist you in driving, parking and maneuvering the vehicle. The driving systems are aids and do not relieve you of your responsibility pertaining to road traffic law. Pay attention to the traffic conditions at all times and intervene when necessary. Be aware of the limitations regarding the safe use of these systems.

Information on radar and ultrasonic sensors
Some driving and driving safety systems use radar or ultrasonic sensors to monitor the area in front of, behind or next to the vehicle (depending on the vehicle’s equipment).
Depending on the vehicle’s equipment, the radar sensors are integrated behind the bumpers and/or behind the radiator grill. The ultrasonic sensors are located in the front and rear bumpers. Keep these parts free of dirt, ice and slush. The sensors must not be covered, for example by bicycle racks, overhanging loads, stickers, foil or foils to protect against stone chipping. Additional license plate bracket can likewise impair the function of the ultrasonic sensors. In the event of damage to the bumpers or radiator grill, or following a collision impacting the bumpers or radiator grill, have the function of the sensors checked at a qualified specialist workshop. If the sensors are damaged, some driving systems and driving safety systems may no longer function properly.

20. Parking Assist PARKTRONIC
21. Rear view camera
22. Active Lane Change Assist
23. Cruise control
24. Blind Spot Assist and Active Blind Spot Assist with exit warning
25. Traffic Sign Assist

Function of ABS
The Anti-lock Brake System (ABS) regulates the brake pressure in critical driving situations:

1. During braking, e.g. at full brake application or insufficient tire traction, the wheels are prevented from locking.
2. Vehicle steerability while braking is ensured.

If ABS intervenes when braking, you will feel a pulsing in the brake pedal. The pulsating brake pedal can be an indication of hazardous road conditions and can serve as a reminder to take extra care while driving.

System limits

1. ABS is active from speeds of approx. 5 mph (8 km/h).
2. ABS may be impaired or may not function if a malfunction has occurred and the yellowThe ABS warning lamp lights up continuously in the instrument cluster after the engine is started.

Function of BAS (Brake Assist System)

WARNING
Risk of an accident caused by a malfunction in BAS (Brake Assist System)
If BAS is malfunctioning, the braking distance in an emergency braking situation is increased.

1. Depress the brake pedal with full force in emergency braking situations. ABS prevents the wheels from locking.

BAS supports your emergency braking situation with additional brake force.

If you depress the brake pedal quickly, BAS is activated:

1. BAS automatically boosts the brake pressure.
2. BAS can shorten the braking distance.
3. ABS prevents the wheels from locking.

The brakes will function as usual once you release the brake pedal. BAS is deactivated.

Functions of ESP® (Electronic Stability Pro‐gram)

WARNING
Risk of skidding if ESP® is malfunctioning
If ESP® is malfunctioning, ESP® cannot carry out vehicle stabilization. In addition, other driving safety systems are switched off.

1. Drive on carefully.
2. Have ESP® checked at a qualified spe‐cialist workshop.

WARNING
Risk of skidding if ESP® is deactivated
If you deactivate ESP®, ESP® cannot carry out vehicle stabilization.

1. ESP® should only be deactivated in the following situations.

Mercedes‑AMG vehicles:
be sure to observe the notes in the Supplement. Otherwise, you may fail to recognize dangers.

ESP® can monitor and improve driving stability and traction in the following situations, within physical limits:

1. When pulling away on wet or slippery roadway.
2. When braking.
3. In strong side winds when you are driving faster than 47 mph (75 km/h).

If the vehicle deviates from the direction desired by the driver, ESP® can stabilize the vehicle by intervening in the following ways:

1. One or more wheels are braked.
2. The engine output is adapted according to the situation.
   ESP® is deactivated if the ESP® OFF warning lamp lights up continuously in the instrument cluster.

Observe the following points when ESP® is deactivated:

1. Driving stability will no longer be improved.
2. Crosswind Assist is no longer active.
3. The drive wheels could spin.
4. ETS/4ETS traction control is still active.
5. When ESP® is deactivated, you are still assisted by ESP® when braking.

If theESP® warning lamp flashes in the instrument cluster, one or several vehicle wheels has reached its grip limit:

1. Adapt the driving style to suit the prevailing road and weather conditions.
2. Do not deactivate ESP® under any circumstances.
3. Only depress the accelerator pedal as far as is necessary.

It may be best to deactivate ESP® in the follow‐ing situations:

1. When using snow chains.
2. In deep snow.
3. On sand or gravel.
4. Spinning the wheels results in a cutting action, which enhances traction.

If the ESP® warning lamp lights up continuously, ESP® is not available due to a malfunction.

Observe the following information:

1. Warning and indicator lamps
2. Display messages

ETS/4ETS (Electronic Traction System) ETS/4ETS traction control is part of ESP® and makes it possible to pull away and accelerate on a slippery roadway.

ETS/4ETS can improve the vehicle’s traction by intervening in the following ways:

1. The drive wheels are braked individually if they spin.
2. More drive torque is transferred to the wheel or wheels with traction.

Influence of drive programs on ESP®
The drive programs enable ESP® to adapt to different weather and road conditions as well as the driver’s preferred driving style. You can select the drive programs using the DYNAMIC SELECT switch.

ESP® characteristics per drive program

Activating/deactivating ESP® (Electronic Stability Program)
ESP® can only be activated/deactivated using quick access when at least one other function is available in quick access. ESP® can otherwise be found in the Assistance menu.

Mercedes‑AMG vehicles:
observe the notes in the Supplement. Otherwise, you may fail to recognize dangers.

1. Select ESP.
   A prompt appears.
2. Select On or Off.
   ESP® is deactivated if theESP® OFF warn‐ing lamp lights up continuously in the instrument cluster.
   Observe the information on warning lamps and display messages which may be shown in the instrument cluster.

Function of ESP® Crosswind Assist
ESP® Crosswind Assist detects sudden gusts of side wind and helps the driver to keep the vehi‐cle in the lane:

1. ESP® Crosswind Assist is active at vehicle speeds between approx. 47 mph (75 km/h) and 125 mph (200 km/h) when driving straight ahead or cornering slightly.
2. The vehicle is stabilized by means of individual brake application on one side.

Function of EBD (electronic brake force dis‐tribution)
EBD is characterized by the following:

1. Monitoring and regulating the brake pressure on the rear wheels.
2. Improved driving stability when braking, especially on bends.

Function of STEER CONTROL
STEER CONTROL helps you by transmitting a noticeable steering force to the steering wheel in the direction required for vehicle stabilization.

This steering recommendation is given particularly in the following situations:

1. Both right wheels or both left wheels are on a wet or slippery road surface when you brake
2. The vehicle starts to skid

System limits
STEER CONTROL may be impaired or may not function in the following situations:

1. ESP® is deactivated.
2. ESP® is malfunctioning.
3. The steering is malfunctioning.
   If ESP® is malfunctioning, you will be assisted further by the electric power steering.

Function of Active Brake Assist
Active Brake Assist consists of the following functions:

1. Distance warning function
2. Autonomous braking function
3. Situation-dependent braking assistance
4. Vehicles with Driving Assistance Package: Evasive Steering Assist

Active Brake Assist can help you to minimize the risk of a collision with vehicles, cyclists or pedestrians, or reduce the effects of such a collision. If Active Brake Assist has detected a risk of collision, a warning tone sounds and theL distance warning lamp lights up in the instrument cluster. Vehicles with PRE-SAFE®: depending on the country, an additional haptic warning occurs in the form of slight, repeated tensioning of the seat belt. If you do not react to the warning, autonomous braking can be initiated in critical situations.

In especially critical situations, Active Brake Assist can initiate autonomous braking directly. In this case, the warning lamp and warning tone occur simultaneously with the braking application. If you apply the brake yourself in a critical situation or apply the brake during autonomous brak‐ing, situation-dependent braking assistance occurs. The brake pressure increases up to maximum full-stop braking if necessary.

If autonomous braking or situation-dependent braking assistance has occurred, display 1 appears in the multifunction display and then automatically goes out after a short time. If the autonomous braking function or the situa‐tion-dependent braking assistance is triggered, additional preventive measures for occupant protection (PRE-SAFE®) may also be initiated.

WARNING
Risk of an accident caused by limited detection performance of Active Brake Assist
Active Brake Assist cannot always clearly identify objects and complex traffic situations.

In such cases, Active Brake Assist might:

1. Give a warning or brake without reason
2. Not give a warning or not brake
3. Always pay careful attention to the traffic situation; do not rely on Active Brake Assist alone. Active Brake Assist is only an aid. The driver is responsible for maintaining a suitable distance to the vehicle in front, vehicle speed and for braking in good time.
4. Be prepared to brake or swerve if necessary.
5. If the system is unavailable, thedisplay appears in the multifunction display.

Also observe the system limits of Active Brake Assist.

The individual subfunctions are available in the following speed ranges:
The distance warning function issues a warning in the following situations:

1. From approximately 4 mph (7 km/h), if your vehicle is critically close to a vehicle or pedestrian, you will hear an intermittent warning tone and theL distance warning lamp lights up in the instrument cluster.
   Vehicles with PRE-SAFE®: depending on the country, an additional haptic warning occurs in the form of slight, repeated ten‐sioning of the seat belt.

Brake immediately or take evasive action, provi‐ded it is safe to do so and the traffic situation allows this.

The distance warning function can aid you in the following situations with an intermittent warning tone and a warning lamp:

The autonomous braking function may intervene at speeds starting from approximately 4 mph (7 km/h) in the following situations:

Situation-dependent braking assistance may intervene at speeds starting from approximately 4 mph (7 km/h) in the following situations:

Canceling a brake application of Active Brake Assist
You can cancel a brake application of Active Brake Assist at any time by:

1. Fully depressing the accelerator pedal or with kickdown.
2. Releasing the brake pedal.

Active Brake Assist may cancel the brake appli‐cation when one of the following conditions is fulfilled:

1. You maneuver to avoid the obstacle.
2. There is no longer a risk of collision.
3. An obstacle is no longer detected in front of your vehicle.

Evasive Steering Assist (only vehicles with Driving Assistance Package)
Evasive Steering Assist has the following characteristics:

1. The ability to detect stationary or moving pedestrians.
2. Assistance through power-assisted steering if it detects a swerving maneuver.
3. Activation by an abrupt steering movement during a swerving maneuver.
4. Assistance during swerving and straightening of the vehicle.
5. Reaction from a speed of approximately 12 mph (20 km/h) up to a speed of approx‐imately 43 mph (70 km/h).

You can prevent the assistance at any time by actively steering.

WARNING
Risk of an accident despite Evasive Steering AssistEvasive Steering Assist cannot always clearly identify objects and complex traffic situa‐tions.
In addition, the steering support of Evasive Steering Assist is generally not sufficient to avoid a collision.

In such cases Evasive Steering Assist can:

1. give an unnecessary warning or provide assistance
2. not give a warning or not provide assistance
3. Always pay careful attention to the traf‐fic situation; do not rely on Evasive Steering Assist alone.
4. Be ready to brake and take evasive action if necessary.
5. Prevent the assistance by actively steering in non-critical driving situa‐tions.
6. Drive at an appropriate speed if pedes‐trians are close to the path of your vehi‐cle.

System limits
Full system performance is not available for a few seconds after switching on the ignition or after driving off.

The system may be impaired or may not function in the following situations:

1. In snow, rain, fog, heavy spray, if there isc glare, in direct sunlight or in greatly varying ambient light.
2. If the sensors are dirty, fogged up, damaged or covered.
3. If the sensors are impaired due to interference from other radar sources, e.g. strong radar reflections in parking garages.
4. If a loss of tire pressure or a faulty tire has been detected and displayed.
5. In complex traffic situations where objects cannot always be clearly identified.
6. If pedestrians or vehicles move quickly into the sensor detection range.
7. If pedestrians are hidden by other objects.
8. If the typical outline of a pedestrian cannot be distinguished from the background.
9. If a pedestrian is not detected as such, e.g. due to special clothing or other objects.
10. On bends with a tight radius.

The Active Brake Assist sensors adjust automatically while a certain distance is being driven after the vehicle has been delivered. Active Brake Assist is unavailable or only partially available during this teach-in period.

Setting Active Brake Assist
The following settings are available:

1. Early
2. Medium
3. Late
4. Select a setting.
   The setting is retained when the engine is next started.

Deactivating Active Brake Assist
It is recommended that you always leave Active Brake Assist activated.

1. Select Off.
   The distance warning function, the autonomous braking function and the Evasive Steer‐ing Assist are deactivated. When the vehicle is next started, the middle setting is automatically selected.
2. If Active Brake Assist is deactivated, the symbol appears in the status bar of the multifunction display.

Speed control cruise control

Function of cruise control
Cruise control regulates the speed to the value selected by the driver. If you accelerate to overtake, for example, the stored speed is not deleted. If you remove your foot from the accelerator pedal after overtaking, cruise control will resume speed regulation back to the stored speed. Cruise control is operated using the correspond‐ing steering wheel buttons. You can store any speed above 15 mph (20 km/h) up to the maxi‐mum speed. If you fail to adapt your driving style, cruise con‐trol can neither reduce the risk of an accident nor override the laws of physics. It cannot take into account road, weather or traffic conditions. Cruise control is only an aid. The driver is responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane.
Mercedes‑AMG vehicles: Cruise control is available up to a maximum speed of 155 mph (250 km/h).

Displays in the multifunction display
The status of cruise control and the stored speed are shown in the multifunction display.

1. Cruise control is selected
2. Speed is saved, cruise control is deactivated
3. Speed is saved, cruise control is activated
4. The segments between the stored speed and the end of the segment display light up in the speedometer.

System limits
Cruise control may be unable to maintain the stored speed on uphill gradients. The stored speed is resumed when the gradient evens out.
Change into a lower gear in good time on long and steep downhill gradients. Take particular note of this when driving a laden vehicle. By doing so, you will make use of the engine’s brak‐ing effect. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly.

Do not use cruise control in the following situations:

1. In traffic situations which require frequent changes of speed, e.g. in heavy traffic, on winding roads.
2. On slippery roads. Accelerating can cause the drive wheels to lose traction and the vehicle could then skid.
3. If you are driving when visibility is poor.

Operating cruise control

WARNING
Risk of accident due to stored speed
If you call up the stored speed and this is lower than your current speed, the vehicle decelerates.

1. Take into account the traffic situation before calling up the stored speed.

Requirements:

1. ESP® must be activated, but not intervening.
2. The driven speed is at least 15 mph (20 km/h).
3. The transmission is in position h.
   
4. To activate cruise control: press rocker switch 1 up.
5. To activate cruise control: press rocker switch 2 up (SET+) or down (SET-).
   The current speed is stored and maintained by the vehicle.
6. Press rocker switch 3 up (RES). The last stored speed is called up and main‐tained by the vehicle.
   If the last stored speed has previously been deleted, the currently driven speed is stored.
7. When you switch off the vehicle, the last speed stored is cleared.
8. To increase/reduce speed: press rocker switch 2 up (SET+) or down (SET-) to the pressure point.
   The stored speed is increased or reduced by 1 mph (1 km/h).
9. Press rocker switch 2 up (SET+) or down (SET-) beyond the pressure point.
   The stored speed is increased or reduced by 5 mph (10 km/h).
10. Accelerate the vehicle to the desired speed.
11. Press rocker switch 2 up (SET+).

If cruise control is activated and Traffic Sign Assist has detected a speed restriction sign with a maximum permissible speed and this is displayed in the instrument cluster, you can choose between the following options:

1. To adopt the detected speed: press rocker switch 3 up (RES).
   The maximum permissible speed shown by the traffic sign is stored and the vehicle maintains this speed.
2. To deactivate cruise control: press rocker switch 3 down (CNCL).
3. To switch off cruise control: press rocker switch 1 down.
4. If you brake, deactivate ESP® or if ESP® intervenes, cruise control is deactivated.

Active Distance Assist DISTRONIC
Function of Active Distance Assist DISTRONIC

Active Distance Assist DISTRONIC maintains the set speed on free-flowing roads. If vehicles in front are detected, the set distance is maintained, if necessary, until the vehicle comes to a halt. The vehicle accelerates or brakes depend‐ing on the distance to the vehicle in front and the set speed. The speed and distance to the vehicle in front are set and saved on the steering wheel on vehicles without the Driving Assistance Package, in the range between 15 mph (20 km/h) and 120 mph (200 km/h) and, on vehicles with the Driving Assistance Package, in the range between 15 mph (20 km/h) and 130 mph (210 km/h).

Other features of Active Distance Assist DISTRONIC:

1. Adjusts the driving style depending on the selected drive program (fuel efficient, comfortable or dynamic)
2. Vehicles with Driving Assistance Package: reacts to stationary vehicles detected in urban speed ranges (except bicycles and motorcycles)
3. Initiates acceleration to the stored speed if the turn signal indicator is switched on to change to the overtaking lane
4. Vehicles with Driving Assistance Package: takes one-sided overtaking restrictions into account on highways or on multi-lane roads with separate roadways (country-dependent)

Vehicles with Active Parking Assist and Driv‐ing Assistance Package:
if the vehicle has been braked to a standstill on multi-lane, separate roadways by Active Distance Assist DISTRONIC, it can automatically follow the vehi‐cle in front driving off again within 30 seconds. If a critical situation is detected when driving off, a visual and acoustic warning is given indicating that the driver must now take control of the vehi‐cle. The vehicle is not accelerated any further.
Active Distance Assist DISTRONIC is only an aid. The driver is responsible for keeping a safe dis‐tance to the vehicle in front, for vehicle speed and for braking in good time.

System limits
The system may be impaired or may not function in the following situations:

1. In snow, rain, fog, heavy spray, if there is glare, in direct sunlight or in greatly varying ambient light.
2. The windshield in the area of the camera is dirty, fogged up, damaged or covered.
3. If the radar sensors are dirty or covered.
4. In parking garages or on roads with steep uphill or downhill gradients.
5. If there are narrow vehicles in front, such as bicycles or motorcycles.

In addition, on slippery roads, braking or accel‐erating can cause one or several wheels to lose traction and the vehicle could then skid.
Do not use Active Distance Assist DISTRONIC in these situations.

WARNING
Risk of accident from acceleration or braking by Active Distance Assist DISTRONIC

Active Distance Assist DISTRONIC may accel‐erate or brake in the following cases, for example:

1. If the vehicle pulls away using Active Distance Assist DISTRONIC.
2. If the stored speed is called up and is considerably faster or slower than the currently driven speed.
3. If Active Distance Assist DISTRONIC no longer detects a vehicle in front or does not react to relevant objects.
4. Always carefully observe the traffic conditions and be ready to brake at all times.
5. Take into account the traffic situation before calling up the stored speed.

WARNING
Risk of accident due to insufficient deceleration by Active Distance Assist DISTRONIC
Active Distance Assist DISTRONIC brakes your vehicle with up to 50% of the maximum possible deceleration. If this deceleration is not sufficient, Active Distance Assist DISTRONIC alerts you with a visual and acoustic warning.

1. In these cases, adjust your speed and keep a sufficient distance.
2. Brake the vehicle yourself and/or take evasive action.

WARNING
Risk of accident if detection function of Active Distance Assist DISTRONIC is impaired

Active Distance Assist DISTRONIC does not react or has a limited reaction:

1. when driving on a different lane or when changing lanes
2. to pedestrians, animals, bicycles or stationary vehicles, or unexpected obstacles
3. to complex traffic conditions
4. to oncoming vehicles and crossing traffic

As a result, Active Distance Assist DISTRONIC may neither give warnings nor intervene in such situations. Always observe the traffic conditions carefully and react accordingly.

Operating Active Distance Assist DISTRONIC Requirements:

1. The vehicle has been started.
2. The electric parking brake is released.
3. ESP® is activated and is not intervening.
4. The transmission is in position h.
5. The driver’s door is closed.
6. Check of the radar sensor system has been successfully completed.
7. Parking Assist PARKTRONIC is not being used to park the vehicle or to exit from a parking space.
8. The vehicle does not skid.

Deactivating Active Distance Assist DISTRONIC:

Press button 1.

Activating Active Distance Assist DISTRONIC

1. To activate without a stored speed: press rocker switch 3 up (SET+) or down (SET-), or press rocker switch 4 up (RES). Remove your foot from the accelerator pedal.
   The current speed is stored and maintained by the vehicle.
2. To activate with a stored speed: press rocker switch 4 up (RES). Remove your foot from the accelerator pedal.

By pressing rocker switch 4 up again, the speed limitation shown in the instrument cluster will be adopted by Active Distance Assist DISTRONIC or variable limiter.

1. To accept the displayed speed restriction when Active Distance Assist DISTRONIC is active: press rocker switch 4 up (RES). The speed limit displayed in the instrument cluster is adopted as the stored speed. The vehicle adapts its speed to that of the vehicle in front, but only up to the stored speed.

Accepting the displayed speed restriction when Distance Assist DISTRONIC is activated

1. Press rocker switch 4 up (RES).
   The speed limit displayed in the instrument cluster is adopted as the stored speed. The vehicle adapts its speed to that of the vehicle in front, but only up to the stored speed.

Pulling away with Active Distance Assist DISTRONIC

1. Remove your foot from the brake pedal and activate Active Distance Assist DISTRONIC.
2. Press rocker switch 4 up (RES).
3. Depress the accelerator pedal briefly and firmly.
   The functions of Active Distance Assist DISTRONIC continue to be carried out.

Deactivating Active Distance Assist DISTRONIC

WARNING
Risk of accident due to Active Distance Assist DISTRONIC still being activated when you leave the driver’s seat
If you leave the driver’s seat while the vehicle is being braked by Active Distance Assist DISTRONIC only, the vehicle can roll away.

1. Always deactivate Active Distance Assist DISTRONIC and secure the vehi‐cle to prevent it from rolling away before you leave the driver’s seat.
2. Press rocker switch 4 down (CNCL).

If you brake, deactivate ESP® or if ESP® intervenes, Active Distance Assist DISTRONIC is deactivated.

Increasing or reducing the speed

1. Press rocker switch 3 up (SET+) or down (SET-) to the pressure point.
   The stored speed is increased or reduced by 1 mph (1 km/h).
2. Press rocker switch 3 up (SET+) or down (SET-) to the pressure point and hold.
   The stored speed is increased or reduced in increments of 1 mph (1 km/h).
3. Press rocker switch 3 up (SET+) or down (SET-) beyond the pressure point.
   The stored speed is increased or reduced by 5 mph (10 km/h).
4. Press rocker switch 3 up (SET+) or down (SET-) and hold beyond the pressure point.
   The stored speed is increased or reduced in increments of 5 mph (10 km/h).

Reducing or increasing the specified dis‐tance from the vehicle in front
Press rocker switch 2 up or down.

Function of Active Speed Limit Assist
The following function is country-dependent and only available in conjunction with the Driving Assistance Package.

If a change in the speed limit is detected and the automatic adoption of speed limits is activated, the new speed is automatically adopted as the stored speed. The driving speed is adjusted when the vehicle is level with the traffic sign at the latest. In the case of signs indicating entry into an urban area, the speed is adapted according to the speed permitted within the urban area. The speed limit display in the Instrument Display is always updated when the vehicle is level with the traffic sign. If there is no speed restriction on an unlimited stretch of road (e.g. on a freeway), the recommended speed is automatically adopted as the stored speed. The system uses the speed stored on an unlimited stretch of road as the recommended speed. If you do not alter the stored speed on an unlimited stretch of road, the recommended speed is 80 mph (130 km/h). If Active Distance Assist DISTRONIC has been put into passive mode by pressing the accelerator pedal, only speed limits that are higher than the set speed are adopted.
Active Speed Limit Assist is only an aid. The driver is responsible for keeping a safe distance from the vehicle in front, for vehicle speed and for braking in good time. The maximum permissible speed also depends on factors such as the road surface and traffic conditions.

System limits
Temporary speed restrictions (e.g. for a certain time or due to weather conditions) cannot be properly detected by the system. The maximum permissible speed applied to a vehicle with a trailer is not detected by the system. In these situations you must adjust your speed yourself.

WARNING
Risk of accident due to Active Speed Limit Assist adapting the vehicle’s speed
The speed adopted by Active Speed Limit Assist may be too high or incorrect in some individual cases, such as:

1. In the wet or in fog
2. When towing a trailer
3. Ensure that the driven speed complies with traffic regulations.
4. Adjust the driving speed to suit current traffic and weather conditions.

The function of route-based speed adaptation
The following function is country-dependent and only available in conjunction with the Driving Assistance Package.

When Active Distance Assist DISTRONIC is acti‐vated, the vehicle speed will be adjusted accord‐ingly to the route events ahead. Depending on the drive program selected, the vehicle negoti‐ates a route event ahead in a fuel-saving, com‐fortable or dynamic manner. When the route event has been passed, the vehicle accelerates again to the stored speed. The set distance to the vehicle in front, vehicles detected ahead and speed restrictions ahead are taken into account. Route-based speed adaptation can be configured in the multimedia system.

The following route events are taken into account:

1. Bends
2. T-intersections, traffic circles and toll stations.
3. Turns and exits

When the toll station is reached, Active Distance Assist DISTRONIC adopts the speed as the stored speed.

Also, the speed is reduced if the turn signal indicator to change lanes is switched on and one of the following situations is detected:

1. Turning off at intersections
2. Driving on slowing-down lanes
3. Driving on lanes adjacent to slowing-down lanes

The driver is responsible for choosing the right speed and observing other road users. This applies in particular to intersections, traffic circles and traffic lights, as route-based speed adaptation does not brake the vehicle to a stand‐still. When route guidance is active, the first speed adjustment is carried out automatically. If the turn signal indicator is switched on, the selected route is confirmed and further speed adjustment is activated.

Speed adjustment is canceled in the following cases:

1. If the turn signal indicator is switched off before the route event.
2. If the driver depresses the accelerator or brake pedal during the process.

System limits
Route-based speed adaptation does not take right of way regulations into account. The driver is responsible for complying with road traffic regulations and driving at a suitable speed.
In difficult conditions, for example unclear roads, lane narrowing, wet road surfaces, snow or ice, or when driving with a trailer, the speed adjust‐ment made by the system may not always be suitable. In these situations the driver must intervene accordingly.

WARNING
Risk of accident in spite of route-based speed adjustment

Route-based speed adjustment might mal‐function or be temporarily unavailable in the following situations:

1. If the driver does not follow the calculated route
2. If map data is not up to date or available
3. In road construction areas
4. In bad weather or road conditions
5. If the accelerator pedal is depressed
6. In the event of electronically displayed speed limitations
7. Adjust the speed to the traffic situation.

Setting route-based speed adaptation

Requirements:

1. Active Distance Assist DISTRONIC is activated.

Active Steering Assist

The function of Active Steering Assist
The following function is country-dependent and only available in conjunction with the Driving Assistance Package. Active Steering Assist is only available up to a speed of 130 mph (210 km/h). The system helps you to stay in the center of the lane by means of moderate steering interventions. Depending on the speed driven, Active Steering Assist uses the vehicles ahead and lane markings as a reference. Depending on the country, in the lower speed range, Active Steering Assist can use the surrounding traffic as a reference. If necessary, Active Steering Assist can then also provide assistance when driving away from the center of the lane to form a rescue lane, for example. When the system is actively steering, the symbol is shown in green in the multifunction display.
If the detection of lane markings and vehicles ahead is impaired, Active Steering Assist switches to passive mode. The system provides no support in this case. During the transition from active to passive status, the symbol is shown as enlarged and flashing. Once the sys‐tem is passive, the symbol is shown as gray in the multifunction display.

Steering and touch detection
The driver is required to keep their hands on the steering wheel at all times and be able to inter‐vene at any time to correct the course of the vehicle and keep it in lane. The driver must expect a change from active to passive mode or vice versa at any time.

If the system detects that the driver has not steered the vehicle for a considerable period of time or has removed their hands from the steer‐ing wheel, an optical warning is given first. Dis‐play 1 appears in the multifunction display. If the driver still does not steer the vehicle, or gives no confirmation to the system, a warning tone sounds in addition to the visual warning message.

The warning is not issued, or is stopped, when the driver gives confirmation to the system:

1. The driver steers the vehicle.
2. The driver presses a steering wheel button or operates Touch Control.

If Active Steering Assist detects that a system limit has been reached, a visual warning is issued and a warning tone sounds.
Active Steering Assist is only an aid. The driver is responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane. Before changing lanes, the driver must make sure that the neighboring lane is free (glance over the shoulder).

System limits
Active Steering Assist has a limited steering torque for lateral guidance. In some cases, the steering intervention is not sufficient to keep the vehicle in the lane or to drive through exits.

The system may be impaired or may not function in the following instances:

1. There is poor visibility, e.g. due to snow, rain, fog, heavy spray, greatly varying ambient light or strong shadows on the roadway.
2. There is glare, e.g. from oncoming traffic, direct sunlight or reflections.
3. Insufficient road illumination.
4. The windshield is dirty, fogged up, damaged or covered in the vicinity of the camera, e.g. by a sticker.
5. No, or several, unclear lane markings are present for one lane, or the markings change quickly, e.g. in a construction area or inter‐sections.
6. The lane markings are worn away, dark or covered up, e.g. by dirt or snow.
7. The distance to the vehicle in front is too small and the lane markings thus cannot be detected.
8. The road is narrow and winding.
9. There are obstacles on the lane or projecting out into the lane, such as object markers.

The system does not provide assistance in the following conditions:

1. On tight bends and when turning.
2. When crossing intersections.
3. At traffic circles or toll stations.
4. When actively changing lane without switching on the turn signal indicator.
5. When the tire pressure is too low.

Depending on the selected vehicle settings, Active Steering Assist may be unavailable. Observe the status display of Active Steering Assist in the multifunction display.

WARNING
Risk of accident if Active Steering Assist unexpectedly stops func‐tioning
If the system limits of Active Steering Assist are reached there is no guarantee that the system will remain active or will keep the vehicle in lane.

1. Always keep your hands on the steering wheel and observe the traffic carefully.
2. Always steer the vehicle paying atten‐tion to traffic conditions.

WARNING
Risk of accident if Active Steering Assist unexpectedly intervenes
A malfunction in the detection of lane markings and objects can occur.

This could cause unexpected steering intervention.

1. Steer according to traffic conditions.

Activating/deactivating Active Steering Assist

Requirements:

1. ESP® is activated, but is not intervening.
2. Active Distance Assist DISTRONIC is activated.
   Function of Active Lane Change Assist
   The following function is country-dependent and only available in conjunction with the Driving Assistance Package.
   Active Lane Change Assist supports the driver when changing lanes by applying steering torque if the driver operates a turn signal indicator.

Assistance when changing lanes is provided if all the following conditions are met:

1. You are driving on a freeway or road with multiple lanes in the direction of travel.
2. The neighboring lane is separated by a broken lane marking.
3. No vehicle is detected in the adjacent lane.
4. The driven speed is between 50 mph (80 km/h) and 110 mph (180 km/h).
5. Active Lane Change Assist is switched on in the multimedia system.
6. Active Steering Assist is switched on and active.

If no vehicle is detected in the adjacent lane and a lane change is permitted, the lane change begins after the driver has activated the turn sig‐nal indicator. This is shown to the driver with a green arrow 2 next to the steering wheel sym‐bol. The Lane Change to the Left message also appears, for example. If Active Lane Change Assist has been activated with the turn signal indicator but a lane change is not immediately possible, a gray arrow 1 appears next to the steering wheel symbol, which remains green. When the lane change assistance starts, the turn signal indicator is automatically activated along with the display in the multifunction display. If the assistance graphic is shown when changing lanes, the lane change display appears with an additional arrow pointing towards the adja‐cent lane. If a lane change is not possible, the arrow fades out after a few seconds and a new lane change must be initiated. An immediate lane change is only possible on freeway sections without speed limits.
If the system is impaired, Active Lane Change Assist may be canceled. If it is canceled, the Lane Change Canceled message appears in the multifunction display and a warning tone sounds.

WARNING
Risk of accident from changing lane to an occupied adjacent lane Change Assist cannot always detect clearly if the adjacent lane is free.
The lane change might be initiated although the adjacent lane is not free.

1. Before changing lanes, make sure that the neighboring lane is free and there is no danger to other road users.
2. Monitor the lane change.

WARNING
Risk of an accident if Lane Change Assist unexpectedly stops functioning
If the system limitations for Lane Change Assist have been reached, there is no guarantee that the system will remain active.

Lane Change Assist cannot then assist you by applying steering torques.

1. Always monitor the lane change and keep your hands on the steering wheel. Observe the traffic conditions and steer and/or brake if necessary.

System limits
The system limitations of Active Steering Assist apply to Active Lane Change Assist.

The system may also be impaired or may not function in the following situations:

1. The sensors in the rear bumper are dirty, damaged or covered by a sticker or ice and snow, for example.
2. The exterior lighting shows a fault.
3. The Active Lane Change Assist sensors adjust automatically while a certain distance is being driven after the vehicle has been delivered. Active Lane Change Assist is unavailable or only partially available during this teach-in process; no arrow appears next to the Active Steering Assist symbol when the turn signal indicator is activated.

Function of Active Emergency Stop Assist
If the driver continually ignores the visual or acoustic warning to put their hands on the steering wheel, the Beginning Emergency Stop mes‐sage appears in the multifunction display. If the driver still does not respond, Active Distance Assist DISTRONIC reduces the speed. The vehi‐cle is decelerated in stages to a standstill. Depending on the country, at speeds below 40 mph (60 km/h) the hazard warning lights switch on automatically.

When the vehicle is stationary, the following actions are carried out:

1. The vehicle is secured with the electric parking brake
2. Active Distance Assist DISTRONIC is ended
3. The vehicle is unlocked
4. If possible, an emergency call is placed to the Mercedes-Benz emergency call center

The driver can cancel the deceleration at any time by performing one of the following actions:

1. Steering
2. Braking or accelerating
3. Pressing a steering-wheel button
4. Operating Touch Control
5. Activating or deactivating Active Distance Assist DISTRONIC

Hill Start Assist holds the vehicle for a short time when pulling away on a hill under the fol‐lowing conditions:

1. Vehicles with automatic transmission:
   The transmission is in position h or k.
2. The electric parking brake is released.

This gives you enough time to move your foot from the brake pedal to the accelerator pedal and depress it before the vehicle begins to roll away.

WARNING
Risk of accident and injury due to the vehicle rolling away
After a short time, Hill Start Assist no longer holds the vehicle and it can roll away.

1. Therefore, swiftly move your foot from the brake pedal to the accelerator pedal. Never attempt to leave the vehi‐cle if it is being held by Hill Start Assist.

HOLD function
The HOLD function holds the vehicle at a stand‐still without requiring you to depress the brake pedal, e.g. while waiting in traffic.
The HOLD function is only an aid. The responsibility for the vehicle safely standing still remains with the driver.

System limits
The HOLD function is only intended to provide assistance when driving and is not a sufficient means of safeguarding the vehicle against rolling away when stationary.

1. The incline must not be greater than 30%.

Activating/deactivating the HOLD function
If you leave the vehicle while only the HOLD function is braking the vehicle, the vehicle can roll away in the following situations:

1. If there is a malfunction in the system or in the power supply.
2. If the HOLD function is deactivated by depressing the accelerator pedal or brake pedal, e.g. by a vehicle occupant.

   The drive program can be adjusted using the DYNAMIC SELECT switch.

Parking Assist PARKTRONIC
The function of Parking Assist PARKTRONIC

Parking Assist PARKTRONIC is an electronic parking assistance system with ultrasound. It monitors the area around your vehicle using multiple sensors 1 on the front bumper and on the rear bumper. Parking Assist PARKTRONIC shows you the distance between your vehicle and a detected obstacle visually and audibly. Parking Assist PARKTRONIC is only an aid. It is not a substitute for your attention to the surroundings. The responsibility for safe maneuvering and parking remains with you. Make sure that there are no persons, animals or objects in the maneuvering area while maneuvering and parking in/exiting parking spaces.

In the standard setting, an intermittent warning tone sounds from a distance of approximately 1.0 ft (0.3 m) to an obstacle in front and approximately 3.3 ft (1.0 m) to an obstacle behind. A continuous warning tone sounds from a distance of approximately 0.7 ft (0.2 m). Using the Warn Early All Around setting in the multimedia system, the warning tones for front and side impact protection can be set to sound at a greater dis‐tance of approximately 3.3 ft (1.0 m) in front and 2.0 ft (0.6 m) on the sides. The Warn Early All Around setting is always active in the rear of the vehicle. If Parking Assist PARKTRONIC is deactivated, Active Parking Assist is unavailable.

Optionally, obstacles detected by Active Parking Assist PARKTRONIC from a distance of approximately 3.3 ft (1.0 m) in front 2 and 2.0 ft (0.6 m) on the sides 3 can also be displayed in the Head-up Display.

System limits
Parking Assist PARKTRONIC does not necessarily take into account the following obstacles:

1. Obstacles below the detection range, e.g. persons, animals or objects.
2. Obstacles above the detection range, e.g. overhanging loads, overhangs or loading ramps of trucks.

The sensors must be free of dirt, ice and slush. Otherwise, they may not function correctly. Clean the sensors regularly, taking care not to scratch or damage them.

Problems with Parking Assist PARKTRONIC

Vehicles without 360° Camera

Vehicles with 360° Camera

Function of the passive side impact protection
Passive side impact protection is an additional Parking Assist PARKTRONIC function which warns the driver about obstacles at the side of the vehicle. A warning is issued when obstacles are detected between the front and rear detection range. In order for an object on the side to be detected, the sensors in the front and rear bumper must first detect the object while you are driving past it. During the parking procedure or maneuvering, objects are detected as the vehicle drives past. If you steer in the direction of a detected obstacle and there is a risk of a lateral collision, a warning is issued. The segments on the sides light up yellow or red, depending on the distance to the obstacle.

In order for lateral front or rear segments to be displayed, the vehicle must first travel a distance of at least half of the vehicle length. Once the vehicle has traveled the length of the vehicle, all of the lateral front and rear segments can be dis‐played.

Active Parking Assist

Function of Active Parking Assist
Active Parking Assist is an electronic parking assistance system which uses ultrasound and is automatically activated during forward travel. The system is operational at speeds below approximately 22 mph (35 km/h). If all requirements are met, the display appears in the multifunction display. The system then independently locates and measures paral‐lel and perpendicular parking spaces on both sides of the vehicle. When Active Parking Assist has detected parking spaces, the display appears in the multi‐function display. The arrows show on which side of the road detected parking spaces are located. They are then shown in the media display. The parking space and, if necessary, the parking direction can be selected as desired. Active Parking Assist calculates a suitable vehicle path, switches on the turn signal indicator and assists you in parking and exiting the parking space.

Vehicles with automatic transmission:
Active Parking Assist provides assistance when chang‐ing gear, accelerating, braking and steering the vehicle.
Active Parking Assist is only an aid. It is not a substitute for your attention to the surroundings. The responsibility for safe maneuvering and parking remains with you. Make sure that no persons, animals or objects etc. are in the maneuvering range.

Active Parking Assist is canceled if, among other things, one of the following actions is carried out:

1. Parking Assist PARKTRONIC is deactivated.
2. Active Parking Assist is deactivated.
3. You begin steering.
4. You apply the parking brake.
5. Vehicles with automatic transmission: you engage transmission position j.
6. ESP® intervenes.
7. You open the doors or the trunk lid while driving.

System limits
Objects located above or below the detection range of Parking Assist PARKTRONIC or Active Parking Assist are not detected when the park‐ing space is being measured. These are also not taken into account when the parking maneuver is calculated, e.g. overhanging loads, overhangs or loading ramps of trucks, or the boundaries of parking spaces. In some circumstances, Active Parking Assist may therefore guide you into the parking space prematurely.

WARNING
Risk of accident due to objects located above or below the detection range of Active Parking Assist
If there are objects above or below the detection range, the following situations may arise:

1. Active Parking Assist may steer too early.
2. Vehicles with automatic transmission: The vehicle may not stop in front of these objects.

This could cause a collision.
In these situations, do not use Active Parking Assist.
Snowfall or heavy rain may lead to a parking space being measured inaccurately. Parking spaces that are partially occupied by trailer drawbars might not be identified as such or be measured incorrectly. Only use Active Parking Assist on level, high-grip ground.

Do not use Active Parking Assist in the following situations:

1. In extreme weather conditions such as ice, packed snow or in heavy rain.
2. When transporting a load that protrudes beyond the vehicle.
3. If the parking space is on a steep downhill or uphill gradient.
4. When snow chains are installed.

Active Parking Assist may also display parking spaces that are not suitable for parking, e.g. the following:

1. Parking spaces where parking is prohibited.
2. Parking spaces on unsuitable surfaces.

You have to accelerate, brake, steer and change gear yourself again.

Function of Drive Away Assist
Drive Away Assist can reduce the severity of an impact when pulling away. If an obstacle is detected in the direction of travel, the vehicle’s speed is briefly reduced to approx. 1 mph (2 km/h). If a critical situation is detected, the É symbol appears in the media display.

WARNING
Risk of accident caused by limited detection performance of Drive Away Assist
Drive Away Assist cannot always clearly iden‐tify objects and traffic situations.

In such cases, Drive Away Assist might:

1. Warn you without reason and limit the vehicle speed.
2. Not warn you or not limit the vehicle speed.
3. Always pay careful attention to the traf‐fic situation; do not rely on Drive Away Assist alone.
4. Be prepared to brake or swerve as nec‐essary, provided the traffic situation permits and that it is safe to take eva‐sive action.

Drive Away Assist is only an aid. It is not a sub‐stitute for your attention to the surroundings. The responsibility for safe maneuvering and parking remains with you. Make sure that no persons, animals or objects etc. are in the maneuvering range.

A risk of a collision may arise in the following sit‐uations, for example:

1. If the driver mixes up the accelerator and brake pedals.
2. If the wrong gear is selected.

Drive Away Assist is active under the following conditions:

1. If Parking Assist PARKTRONIC is activated.
2. Every time the gear is changed to k or h when the vehicle is at a standstill.
3. If the detected obstacle is less than approx. 3.3 ft (1.0 m) away.
4. If the maneuvering assistant function is activated in the multimedia system.

System limits
The performance of Drive Away Assist is limited on inclines.
Also observe the system limits of Parking Assist PARKTRONIC.

Function of Cross Traffic Alert
Also read the instructions on Blind Spot Assist.

Vehicles with Blind Spot Assist:
Cross Traffic Alert can warn drivers of any crossing traffic when backing up out of a parking space. The radar sensors in the bumper also monitor the area adjacent to the vehicle. If a critical situation is detected, symbol 1 appears in the media dis‐play. If the driver does not respond to the warn‐ing, the vehicle’s brakes can be applied automat‐ically.
If the radar sensors are obstructed by vehicles or other objects, detection is not possible.

Cross Traffic Alert is active under the following conditions:

1. If Blind Spot Assist is activated.
2. If the vehicle is backing up at walking pace.
3. If the maneuvering assistant function is activated in the multimedia system.

System limits
Cross Traffic Alert is not available on inclines.
Also observe the system limits of Active Blind Spot Assist.

ATTENTION ASSIST

Function of ATTENTION ASSIST
ATTENTION ASSIST assists you on long, monotonous journeys, e.g. on highways and trunk roads. If ATTENTION ASSIST detects indicators of fatigue or increasing lapses in concentration on the part of the driver, it suggests taking a break.
ATTENTION ASSIST is only an aid. It cannot always detect fatigue or lapses in concentration in time. The system is not a substitute for a well-rested and attentive driver. On long journeys, take regular breaks in good time that allow for adequate recuperation.

You can choose between two settings:

1. Standard: normal system sensitivity.
2. Sensitive: higher system sensitivity. The driver is warned earlier and the attention level detected by ATTENTION ASSIST is adapted accordingly.

If drowsiness or increasing lapses in concentration are detected, the ATTENTION ASSIST: Take a Break! warning appears in the Instrument Display. You can acknowledge the message and take a break where necessary. If you do not take a break and ATTENTION ASSIST continues to detect increasing lapses in concentration, you will be warned again after a minimum of 15 minutes.

You can have the following status information for ATTENTION ASSIST displayed in the assistance menu of the on-board computer:

1. The length of the journey since the last break.
2. The attention level determined by ATTENTION ASSIST:
   1. The fuller the circle, the higher the attentional level determined
   2. As your attention wanes, the circle in the center of the display becomes smaller

If ATTENTION ASSIST is unable to calculate the attention level and cannot issue a warning, the System Suspended message appears.
If a warning is given in the Instrument Display, the multimedia system offers to search for a rest area. You can select a rest area and start navigation to this rest area. This function can be activa‐=ted and deactivated in the multimedia system.
If ATTENTION ASSIST is deactivated, the symbol appears in the assistance graphic in the Instrument Display when the engine is running. ATTENTION ASSIST is activated automatically when the engine is re-started. The last selected sensitivity level remains stored.

System limits
ATTENTION ASSIST is active in the 37 mph (60 km/h) to 124 mph (200 km/h) speed range.
The functionality of ATTENTION ASSIST is restricted, and warnings may be delayed or not occur at all in the following situations:

1. If you have been driving for less than approximately 30 minutes.
2. If the road condition is poor (uneven road surface or potholes).
3. If there is a strong side wind.
4. If you adopt a sporty driving style (high cornering speeds or high rates of acceleration).
5. If the Steering Assist function of Active Distance Assist DISTRONIC is active.
6. If the time has been set incorrectly.
7. In active driving situations, if you change lanes and vary your speed frequently.

The ATTENTION ASSIST tiredness or alertness assessment is deleted and restarted when con‐tinuing the journey in the following situations:

1. If you switch off the engine.
2. If you unfasten your seat belt and open the driver’s door (e.g. changing drivers or taking a break).

Setting options

1. Select Standard, Sensitive or Off.

Suggesting a rest area

1. Select Suggest Rest Area.
2. Activate or deactivate the function.
   If ATTENTION ASSIST detects fatigue or increasing lack of attention, it suggests a rest area in the vicinity.
3. Select the suggested rest area.
   You are guided to the selected rest area.

Traffic Sign Assist
Function of Traffic Sign Assist

Traffic Sign Assist detects traffic signs with multifunction camera 1. It assists you by display‐ing detected speed limits and overtaking restric‐tions in the instrument cluster and optionally in the Head-up Display or central display. Since Traffic Sign Assist also uses the data stored in the navigation system, it can update the display in the following situations without detecting traffic signs:

1. When the vehicle changes roads, e.g. freeway entry or exit roads.
2. When a village or city boundary which is stored in the digital map is passed.
   The camera also detects traffic signs with a restriction indicated by an additional sign (e.g. when wet).

Traffic Sign Assist is only an aid. The driver is responsible for keeping a safe distance from the vehicle in front, for vehicle speed and for braking in good time.

Warning when the maximum permissible speed is exceeded
The system can warn you if you unintentionally exceed the maximum permissible speed. To do this, you can specify in the multimedia system by how much the maximum permissible speed can be exceeded before a warning is issued. You can specify whether the warning is to be just a visual warning or an acoustic one as well.

Display in the Instrument Display

Instrument Display in the Widescreen Cockpit

1. Permissible speed
2. Permissible speed when there is a restriction
3. Additional sign with restriction
4. Vehicles with a standard Instrument Display: a + symbol next to a traffic sign in the Instrument Display indicates that additional traffic signs have been detected. These can also be displayed in the media display and optionally in the Head-up Display.

If Traffic Sign Assist cannot determine the cur‐rent maximum permissible speed (e.g. due to missing signs), the following display appears in the Instrument Display:

This is displayed continuously if the vehicle is in a country where Traffic Sign Assist is not sup‐ported. Traffic Sign Assist is not available in all countries.
Also observe the information on display mes‐sages in Traffic Sign Assist.

System limits
The system may be impaired or may not function in the following situations:

1. If there is poor visibility, e.g. due to insufficient illumination of the road, if there are highly variable shade conditions or in rain, snow, fog or heavy spray.
2. If there is glare, e.g. from oncoming traffic, direct sunlight or reflections.
3. If the windshield in the area of the multifunction camera is dirty, or if the camera is fog‐ged up, damaged or covered.
4. If the traffic signs are hard to detect, e.g. due to dirt or snow, or because they are covered or due to insufficient lighting.
5. If the information in the navigation system’s digital map is incorrect or out-of-date.
6. If the signs are ambiguous, e.g. traffic signs on construction sites or in adjacent lanes.
7. If you turn sharply, when passing traffic signs outside the camera’s field of vision.

Setting Traffic Sign Assist
Requirements:

1. Only vehicles with Driving Assistance Package:
   Active Distance Assist DISTRONIC must be activated for the automatic adoption of speed limits.

Activating/deactivating automatic adoption of speed limits (only vehicles with Driving Assistance Package)

1. Select Limit Adoption.
2. Activate or deactivate the function.
   The speed limits detected by Traffic Sign Assist are automatically adopted by Active Distance Assist DISTRONIC.

Blind Spot Assist and Active Blind Spot Assist with exit warning

Function of Blind Spot Assist and Active Blind Spot Assist with exit warning
Blind Spot Assist and Active Blind Spot Assist use two lateral, rear-facing radar sensors to monitor the area up to 130 ft (40 m) behind and 10 ft (3 m) next to your vehicle.
If a vehicle is detected at speeds above approximately 8 mph (12 km/h) and this vehicle subsequently enters the monitoring range directly next to your vehicle, the warning lamp in the outside mirror lights up red. If a vehicle is detected close to the side of your vehicle, the red warning lamp in the outside mir‐ror flashes. If you switch on the turn signal indi‐cator in the corresponding direction, a warning tone sounds once. If the turn signal indicator remains switched on, all other detected vehicles are indicated only by the flashing of the red warning lamp. If you overtake a vehicle quickly, no warning is given.

WARNING
Risk of accident despite Blind Spot Assist
Blind Spot Assist does not react to vehicles approaching and overtaking you at a greatly different speed.

As a result, Blind Spot Assist cannot warn drivers in this situation.

1. Always pay careful attention to the traf‐fic situation and maintain a safe dis‐tance at the side of the vehicle.

Blind Spot Assist and Active Blind Spot Assist are only aids. They may fail to detect some vehicles and are no substitute for attentive driving. Always ensure that there is sufficient distance to the side for other road users and obstacles.

Exit warning
The exit warning is an additional function of Blind Spot Assist and can warn vehicle occu‐pants about approaching vehicles when leaving the vehicle when stationary.

WARNING
Risk of accident despite exit warning
The exit warning reacts neither to stationary objects nor to vehicles approaching you at a greatly different speed.

As a result, the exit warning cannot warn drivers in these situations.

1. Always pay particular attention to the traffic situation when opening the doors and make sure there is sufficient clearance.

If there is a vehicle in the monitoring range, this is indicated in the outside mirror. If a vehicle occupant opens the door on the side with the warning, a warning tone sounds and the warning lamp in the outside mirror starts to flash. This additional function is only available when Blind Spot Assist is activated and up to a maxi‐mum of three minutes after the ignition has been switched off. The exit warning is no longer available once the warning lamp in the outside mirror flashes three times.
The exit warning is only an aid and not a substitute for the attention of vehicle occupants. The responsibility for opening and closing the doors and for leaving the vehicle remains with the vehicle occupants.

System limits
Blind Spot Assist and Active Blind Spot Assist may be limited in the following situations:

1. If there is dirt on the sensors or the sensors are obscured
2. In poor visibility, e.g. due to fog, heavy rain or snow
3. If there are narrow vehicles, e.g. bicycles or motorbikes
4. If the road has very wide or narrow lanes
5. If vehicles are not driving in the middle of their lane Warnings may be issued in error when driving close to crash barriers or similar solid lane bor‐ders. Always make sure that there is sufficient distance to the side for other traffic or obstacles. Warnings may be interrupted when driving along‐side long vehicles, for example trucks, for a pro‐longed time.
   Blind Spot Assist is not operational when reverse gear is engaged.

The exit warning may be limited in the following situations:

1. When the sensors are covered by adjacent vehicles in narrow parking spaces
2. When people approach the vehicle
3. In the event of stationary or slowly moving objects

Function of brake application (Active Blind Spot Assist)
The brake application function is only available for vehicles with a Driving Assistance Package.
If Active Blind Spot Assist detects a risk of a side impact in the monitoring range, a course-cor‐recting brake application is carried out. This is designed to help you avoid a collision.
The course-correcting brake application is available in the speed range between approximately 20 mph (30 km/h) and 125 mph (200 km/h).

WARNING
Risk of accident despite brake application of Active Blind Spot Assist
A course-correcting brake application cannot always prevent a collision.

1. Always steer, brake or accelerate yourself, especially if Active Blind Spot Assist warns you or makes a course-correcting brake application.
2. Always maintain a safe distance at the sides.

WARNING
Risk of accident despite Active Blind Spot Assist
Active Blind Spot Assist does not react to the following:

1. If vehicles overtake too closely on the side, placing them in the blind spot area
2. Vehicles approaching and overtaking you at a greatly different speed

As a result, Active Blind Spot Assist may nei‐ther give warnings nor intervene in such sit‐uations.
Always pay careful attention to the traf‐fic situation and maintain a safe distance at the side of the vehicle.

If a course-correcting brake application occurs, the red warning lamp flashes in the outside mir‐ror and a warning tone sounds. In addition, a dis‐play 1 indicating the danger of a side collision appears in the multifunction display. In rare cases, the system may make an inappro‐priate brake application. This brake application may be interrupted at any time if you steer slightly in the opposite direction or accelerate.

System limits
Either a course-correcting brake application appropriate to the driving situation, or none at all, may occur in the following situations:

1. Vehicles or obstacles, e.g. crash barriers, are located on both sides of your vehicle.
2. A vehicle approaches too closely on the side.
3. You have adopted a sporty driving style with high cornering speeds.
4. You brake or accelerate significantly.
5. A driving safety system intervenes, e.g. ESP® or Active Brake Assist.
6. ESP® is deactivated.
7. A loss of tire pressure or a faulty tire is detected.

Activating/deactivating Blind Spot Assist or Active Blind Spot Assist

1. Activate or deactivate Blind Spot Assist.
2. Activate or deactivate Act. Blind Spot Assist.
3. Depending on the vehicle’s equipment, Blind Spot Assist or Active Blind Spot Assist is available.

Active Lane Keeping Assist
Function of Active Lane Keeping Assist

Active Lane Keeping Assist monitors the area in front of your vehicle by means of multifunction camera 1. It serves to protect you against unin‐tentionally leaving your lane. You will be warned by vibration pulses in the steering wheel and guided by a course-correcting brake application back into your lane.

You are warned by vibration pulses in the steer‐ing wheel in the following circumstances:

1. Active Lane Keeping Assist detects a lane marking.
2. A front wheel drives over this lane marking.

You will also be guided back into your lane by means of a course-correcting brake application if the following conditions are met:

1. Active Lane Keeping Assist detects lane markings on both edges of the lane.
2. A front wheel drives over a solid lane marking.
   You can activate or deactivate the Active Lane Keeping Assist warning.

The status of Active Lane Keeping Assist is dis‐played in the on-board computer:

1. (green): Active Lane Keeping Assist is activated and operating.
2. (gray): Active Lane Keeping Assist is activated, but not operating.
3.  Active Lane Keeping Assist is deactivated or there is a malfunction.

Active Lane Keeping Assist can neither reduce the risk of an accident if you fail to adapt your driving style nor override the laws of physics. It cannot take into account road, weather or traffic conditions. Active Lane Keeping Assist is only an aid. You are responsible for maintaining a safe distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane. Active Lane Keeping Assist can bring the vehicle back into the lane with a lane-correcting brake application. In the case of a broken lane marking being detected, a brake application will only be made if a vehicle has been detected in the adja‐cent lane. Oncoming traffic can be detected.

Vehicles with Driving Assistance Package or Driving Assistance Plus Package: overtaking vehicles and vehicles in adjacent lanes can also be detected.
Vehicles without Driving Assistance Pack‐age or Driving Assistance Plus Package: a lane-correcting brake application also takes place when, in addition to a broken lane mark‐ing, the edge of a firm road surface is detected (e.g. central reservation). Active Lane Keeping Assist is available in the speed range between 37 mph (60 km/h) and 124 mph (200 km/h).

If a lane-correcting brake application occurs, dis‐play 1 appears in the multifunction display.

Sensitivity of Active Lane Keeping Assist
The availability of the following function is country-dependent.

A lane-correcting brake application also occurs in the Sensitive setting in the following situa‐tions:

1. Active Lane Keeping Assist detects a solid lane marking.
2. A front wheel drives over this lane marking.

System limits
No lane-correcting brake application occurs in the following situations:

1. You clearly and actively steer, brake or accelerate.
2. You have switched on the turn signal indicator (situation-dependent).
3. A driving safety system intervenes, such as ESP®, Active Brake Assist or Active Blind Spot Assist.
4. You have adopted a sporty driving style with high cornering speeds or high rates of accel‐eration.
5. When ESP® is deactivated.
6. If a loss of tire pressure or a faulty tire has been detected and displayed.

The system may be impaired or may not function in the following situations:

1. If there is poor visibility, e.g. due to insufficient illumination of the road, if there are highly variable shade conditions or in rain, snow, fog or heavy spray.
2. If there is glare, e.g. from oncoming traffic, the sun or reflections.
3. If the windshield in the area of the multifunction camera is dirty, or if the camera is fog‐ged up, damaged or covered.
4. If there are no lane markings, or several unclear lane markings are present for one lane, e.g. around roadworks.
5. If the lane markings are worn, dark or covered.
6. If the distance to the vehicle in front is too short and thus the lane markings cannot be detected.
7. If the lane markings change quickly, e.g. lanes branch off, cross one another or merge.
8. If the roadway is very narrow and winding.

Vehicles without Driving Assistance Package:
Active Lane Keeping Assist uses radar sen‐sors to monitor several areas around the vehicle. If the radar sensors in the rear bumper are dirty or covered with snow, the system may be impaired or may not function. If an obstacle in the lane in which you are driving has been detected, no lane-correcting brake application occurs.
