Cruise Control

The cruise control can store and maintain speeds above 25 mph. Additionally, at least the third gear must be engaged on some manual transmissions. On automatic transmission, position D or the second or a higher gear in position M must be selected. Deviations from the stored speeds may occur when driving uphill or downhill. The system maintains the vehicle speed at the preset speed by the driver, without any action on the accelerator pedal. The preset speed can be exceeded temporarily by pressing the accelerator pedal firmly. The status and preset speed is displayed in the Driver Information Centre. Do not use the cruise control if it is not advisable to maintain a constant speed.

Switching on the system

The speed limit recognition may not operate correctly if traffic signs do not comply with the Vienna Convention on Road Signs and Signals.

Adaptive cruise control
The adaptive cruise control is an enhancement of the cruise control with the additional feature of maintaining a certain following distance to the vehicle ahead.

It uses radar and camera sensors to detect the vehicles ahead. If no vehicle is detected in the driving path, the adaptive cruise control will behave like a conventional cruise control.
The adaptive cruise control automatically decelerates the vehicle when approaching a slower moving vehicle. It then adjusts the vehicle speed to follow the vehicle ahead at the selected following distance. The vehicle speed increases or decreases to follow the vehicle ahead, but will not exceed the set speed. It may apply limited braking with activated brake lights.
If the vehicle ahead accelerates or changes lane, the adaptive cruise control progressively accelerates the vehicle to return to the stored set speed. If the driver operates the turn lights to overtake a slower vehicle, the adaptive cruise control allows the vehicle to temporarily approach the vehicle ahead to help passing it. However, the set speed will never be exceeded.
The adaptive cruise control can store set speeds over 25 mph for manual transmission. If the vehicle ahead is moving too slowly and the selected following distance cannot be maintained anymore, a warning chime is given and a message is displayed in the Driver Information Centre. The message prompts the driver to take back control of the vehicle. On vehicles with automatic transmission, the system can brake the vehicle until a full stop.

WARNING
The complete driver attention is always required while driving with adaptive cruise control. The driver stays fully in control of the vehicle because the brake pedal, the accelerator pedal and the button Ñ have priority over any adaptive cruise control operation.

Switching on the system

Press.
is indicated in the Driver Information Centre. The system is still not active.

Activation of the functionality

Setting speed by the driver
The adaptive cruise control has to be switched on manually at a speed between 25 mph and 112 mph. For vehicles with automatic transmission, the automatic selector lever must be in position D or M.
Accelerate to the desired speed and move the thumb wheel to SET/-. The current speed is stored and maintained.

The speed value is indicated in the Driver Information Centre.
The preset speed can then be changed by moving thumb wheel to RES/+ to increase or SET/- to decrease the speed. Move thumb wheel repeatedly to change speed in small steps, move and hold to change speed in large steps. When the adaptive cruise control is operating, the stop-start system is automatically deactivated.

Adopting speed by the speed limit recognition
The intelligent speed adaptation informs the driver when a speed limit is detected by the speed limit recognition. The detected speed limit can be taken over as new set speed for the adaptive cruise control.
Using the camera at the top of the windscreen, this system detects and reads speed limit and end of speed limit signs.
If the adaptive cruise control is active, the recognised speed limit will be displayed in the Driver Information Centre and MEM illuminates if the difference between set speed and speed limit is more than 6 mph.
Press MEM on the steering wheel to request saving of the suggested speed.
Press MEM on the steering wheel once more to confirm and save the new speed setting.
This speed limit is now the new set speed of the adaptive cruise control. The function can be activated or deactivated in the vehicle personalisation.

Overriding set speed
It is always possible to drive faster than the selected set speed by depressing the accelerator pedal. When the accelerator pedal is released, the vehicle returns to the stored speed. If a slower moving vehicle is ahead, the following distance selected by the driver is restored. If the set speed is exceeded, the indicated speed setting disappears and a warning message is displayed.

WARNING
Accelerating by the driver deactivates automatic braking by the system. This is indicated as a pop-up warning in the Driver Information Centre.

Resuming stored speed
Move the thumb wheel to RES/+ at a speed above 25 mph. The adaptive cruise control is activated with the stored set speed.

Adaptive cruise control on vehicles with automatic transmission
For vehicles with automatic transmission, adaptive cruise control allows to maintain the selected distance behind a braking vehicle until a complete stop is reached.
If the system has stopped your vehicle behind another vehicle, then the set speed is replaced by a green control indicator. This symbol notifies, that the vehicle is hold automatically in stop position.
When the vehicle ahead drives away within some seconds and the traffic conditions allow a restart of the vehicle, then active cruise control is resumed automatically.
If the stopped vehicle ahead was stopped for a longer time and then begins to move forward, the green control indicator. will flash and a warning chime will sound as a reminder to check traffic before resuming. When the vehicle ahead drives away, depress the accelerator pedal or pressto resume adaptive cruise control.
If the vehicle stays stopped for more than 5 minutes or if the driver’s door is opened and the driver’s seat belt is unfastened, then the electric parking brake is applied automatically to hold the vehicle. Control indicatorwill illuminate. To release electric parking brake, press the accelerator pedal.

WARNING
When the system is deactivated or cancelled, the vehicle will no longer be held at a stop and can start moving. Be always prepared to manually apply the brake to hold the vehicle stationary.
Do not leave the vehicle while it is being held at a stop by adaptive cruise control. Always move selector lever to park position P and switch off the ignition before leaving the vehicle.

Setting the following distance
When adaptive cruise control detects a slower moving vehicle in the driving path, it will adjust the vehicle speed to maintain the following distance selected by the driver.
The following distance can be set to close (1 bar), normal (2 bars) or far (3 bars).
If the engine is running and the adaptive cruise control is enabled (grey) or active (green), you can modify the following distance setting:
Press, the current setting is shown in the Driver Information Centre. Pressagain to change the following distance: The new setting is displayed in the Driver Information Centre.
The selected following distance is indicated by full bars in the adaptive cruise control page.

WARNING
The driver accepts full responsibility for the appropriate following distance based on traffic, weather and visibility conditions. Following distance must be adjusted or the system switched off when required by the prevailing conditions.

Detecting the vehicle ahead
If the system detects a vehicle in the driving path, the adaptive cruise control symbol displayed in the Driver Information Centre changes from to.

Deactivation of the functionality

Press , the adaptive cruise control is in pause mode and a message is displayed. The vehicle is driven without adaptive cruise control.
The adaptive cruise control is deactivated, but not disabled. The last stored set speed remains in memory for later usage.

The adaptive cruise control is deactivated automatically in the following cases:

1. The brake pedal is depressed.
2. The vehicle accelerates above 112 mph (manual and automatic transmission) or slows down below 25 mph (manual transmission).
3. The electric parking brake is applied.
4. The traction control system or electronic stability control is deactivated or operating.
5. The selector lever of automatic transmissions is neither in D nor in M.
6. A fault is detected in the electronic stability control or the radar system.
7. Immediately after the clutch pedal has been depressed or a few seconds after the clutch pedal has been depressed (depending on the manual transmission).

Switching off the system
Press, the adaptive cruise control mode is disabled and the adaptive cruise control indication extinguishes in the Driver Information Centre.
Pressingto activate the speed limiter deactivates adaptive cruise control.
Switching off the ignition deletes the stored set speed.

Driver’s attention

1. Use the adaptive cruise control carefully on bends or mountain roads, as it can lose the vehicle ahead and needs time to detect it again.
2. Do not use the system on slippery roads as it can create rapid changes in tyre traction (wheel spinning), so that you could lose control of the vehicle.
3. Do not use the adaptive cruise control during rain, snow or heavy dirt, as the radar sensor can be covered by a water film, dust, ice or snow. This reduces or suppresses completely the visibility. In case of sensor blockage, clean the sensor cover.
4. Do not use the system when the spare wheel is in use.

System limits

WARNING
The system’s automatic brake force does not permit hard braking and the braking level may not be sufficient to avoid a collision.

1. After a sudden lane change, the system needs a certain time to detect the next preceding vehicle. So if a new vehicle is detected, the system may accelerate instead of braking.
2. The adaptive cruise control does ignore the oncoming traffic.
3. The adaptive cruise control does not consider pedestrians and animals for braking and driving off.
4. The adaptive cruise control considers stopped vehicles only at low speed.
5. Do not use the adaptive cruise control when towing a trailer.
6. Do not use the adaptive cruise control on roads with an incline of more than 10%.

As the radar’s field of detection is quite narrow, it is possible that the system may not detect:

1. vehicles of reduced width, e.g. motorcycles, scooters
2. vehicles not running in the middle of the lane
3. vehicles entering a corner
4. vehicles suddenly pulling out.

Bends

The adaptive cruise control calculates a predicted path based on the centrifugal force. This predicted path considers the current bend characteristic, but cannot consider a future bend change. The system may lose the current vehicle ahead or consider a vehicle which is not in the actual lane. This can happen when entering or exiting a bend or if the bend gets stronger or weaker. If it no longer detects any vehicle ahead, then      will extinguish. If the centrifugal force is too high in a bend, the system slows down the vehicle slightly. This braking level is not designed to avoid spinning-off the bend. The driver is responsible for reducing the selected speed before entering a bend and in general to adapt the speed to the road type and to existing speed limits.

Motorways
On motorways, adapt the set speed to the situation and the weather. Always consider that adaptive cruise control has a limited visibility range, a limited braking level and a certain reaction time to verify if a vehicle is on the driving path or not. Adaptive cruise control may not be able to brake the vehicle in time to avoid a collision with a much slower vehicle or after a lane change. This is particularly true while driving fast or if the visibility is reduced due to weather conditions.
While entering or exiting a motorway, adaptive cruise control may lose the vehicle ahead and accelerate up to the set speed. For this reason, decrease the set speed before the exit or before the entry.

Vehicle path changes

If another vehicle enters your driving path, adaptive cruise control will first consider the vehicle when it is completely in your path. Be ready to take action and depress the brake pedal if you need to brake more quickly.

Hill considerations

WARNING
Do not use the adaptive cruise control on steep hill roads.

System performance on hills depends on vehicle speed, vehicle load, traffic conditions and the road gradient. It may not detect a vehicle in your path while driving on hills. On steep hills, you may have to use the accelerator pedal to maintain your vehicle speed. When going downhill you may have to brake to maintain or reduce your speed.
Note that applying the brake deactivates the system.

Radar unit

The radar unit is located in the middle of the front bumper.

WARNING
The radar unit was aligned carefully during manufacture. Therefore, in the event of a front-end impact, do not use the system. The front bumper may appear to be intact, however the sensor behind may be affected and react incorrectly. After an accident, consult a workshop to verify and adjust the radar unit position. Do not use a license plate support on the front bumper to ensure proper radar unit functionality.

Fault
In the event of an adaptive cruise control fault, a warning light is illuminated in the instrument cluster and a warning message is displayed in the Driver Information Centre accompanied by an audible signal.
The adaptive cruise control may not operate correctly if traffic signs do not comply with the Vienna Convention on Road Signs and Signals.
Have the system checked by a dealer or a qualified workshop. As a safety measure, do not use the system if the brake lights are faulty. Do not use the system if the front bumper is damaged
