Cruise control
General notes
Cruise control maintains a constant road speed for you. It brakes automatically in order to avoid exceeding the set speed. Change into a lower gear in good time on long and steep downhill gradients. This is especially important if the vehicle is laden. By doing so, you will make use of the braking effect of the engine. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly.
Use cruise control only if road and traffic conditions make it appropriate to maintain a steady speed for a prolonged period. You can store any road speed above 20 mph
(30 km/h).

Important safety notes
If you fail to adapt your driving style, cruise control can neither reduce the risk of an accident nor override the laws of physics. Cruise control cannot take into account the road, traffic and weather conditions. Cruise control is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in your lane.
Do not use cruise control:

• in road and traffic conditions that do not allow you to maintain a constant speed e.g. in heavy traffic or on winding roads
  Ron slippery road surfaces. Braking or accelerating could cause the drive wheels to lose traction and the vehicle could then skid
• when there is poor visibility, e.g. due to fog, heavy rain or snow
  If there is a change of drivers, advise the new driver of the speed stored.

Cruise control lever

1. To activate or increase speed
2. To activate or reduce speed
3. To deactivate cruise control
4. To activate at the current speed/last stored speed
   When you activate cruise control, the stored speed is shown in the multifunction display for five seconds. In the speedometer, the segments between the stored speed and the maximum speed light up.

Storing and maintaining the current speed 
You can store the current speed if you are driving faster than 20 mph (30 km/h).

• Accelerate the vehicle to the desired speed.
• Briefly press the cruise control lever up : or down 1.
• Remove your foot from the accelerator pedal.
  Cruise control is activated. The vehicle automatically maintains the stored speed.
  Cruise control may be unable to maintain the stored speed on uphill gradients. The stored speed is resumed when the gradient evens out. Cruise control maintains the stored speed on downhill gradients by automatically applying the brakes.

Calling up the last speed stored
WARNING If you call up the stored speed and it is lower than the current speed, the vehicle decelerates. If you do not know the stored speed, the vehicle could decelerate unexpectedly. There is a risk of an accident.
Pay attention to the road and traffic condi-tions before calling up the stored speed. If you do not know the stored speed, store the desired speed again.

• Briefly pull the cruise control lever towards you 1.
• Remove your foot from the accelerator pedal.
  The first time cruise control is activated, it stores the current speed or regulates the speed of the vehicle to the previously stored speed.

Deactivating cruise control
There are several ways to deactivate cruise control:

• Briefly press cruise the control lever forwards or Brake 1.
  Cruise control is automatically deactivated if:
• you engage the electric parking brake Ryou are driving at less than 20 mph (30 km/h)
• ESP® intervenes or you deactivate ESP®
• you shift the transmission to position N while driving
  If cruise control is deactivated, you will hear a
  warning tone. You will see the CruiseCruise Con‐Con‐troltrol OffOff message in the multifunction display for approximately five seconds.
  When you switch off the engine, the last speed stored is cleared.

DISTRONIC PLUS
General notes
DISTRONIC PLUS regulates the speed and automatically helps you maintain the distance to the vehicle detected in front. Vehicles are detected with the aid of the radar sensor system. DISTRONIC PLUS brakes automatically so that the set speed is not exceeded. Change into a lower gear in good time on long and steep downhill gradients. This is especially important if the vehicle is laden. By doing so, you will make use of the braking effect of the engine. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly.
If DISTRONIC PLUS detects that there is a risk of a collision, you will be warned visually and acoustically. DISTRONIC PLUS cannot pre-vent a collision without your intervention. An intermittent warning tone will then sound and the distance warning lamp will light up in the instrument cluster. Brake immediately in order to increase the distance to the vehicle in front or take evasive action provided it is safe to do so.
DISTRONIC PLUS operates in range between 0 mph (0 km/h) and 120 mph (200 km/h).
Do not use DISTRONIC PLUS while driving on roads with steep gradients.
As DISTRONIC PLUS transmits radar waves, it can resemble the radar detectors of the responsible authorities. You can refer to the relevant chapter in the Operator’s Manual if questions are asked about this.

Operation

Useful information
This Operator’s Manual describes all models and all standard and optional equipment of your vehicle available at the time of publication of the Operator’s Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety-related systems and functions.
Read the information on qualified specialist workshops (page 26).

Important safety notes

WARNING
If wheels and tires of the wrong size are used, the wheel brakes or suspension components may be damaged. There is a risk of an acci-dent.
Always replace wheels and tires with those that fulfill the specifications of the original part.
When replacing wheels, make sure to use the correct:

• designation
• model
  When replacing tires, make sure to use the correct:
• designation
• manufacturer
• model

Accessories that are not approved for your vehicle by Mercedes-Benz or are not being used correctly can impair the operating safety.
Before purchasing and using non-approved accessories, visit a qualified specialist work-shop and inquire about:

• suitability
• legal stipulations
• factory recommendations
  Information on the sizes and types of wheels and tires for your vehicle can be found under “Wheel/tire combinations” (Y page 388). Information on tire pressure can be found:
• on the vehicle’s Tire and Loading Information placard on the B-pillar (Y page 372) Ron the tire pressure label on the fuel filler flap (page 168)
  Runder “Tire pressure” (page 365)

Information on driving
Check the tire pressure when the vehicle is heavily laden and adjust prior to a trip.
While driving, pay attention to vibrations, noises and unusual handling characteristics, e.g. pulling to one side. This may indicate that the wheels or tires are damaged. If you sus-pect that a tire is defective, reduce your speed immediately. Stop the vehicle as soon as possible to check the wheels and tires for damage. Hidden tire damage could also be causing the unusual handling characteristics. If you find no signs of damage, have the tires and wheels checked at a qualified specialist workshop.
When parking your vehicle, make sure that the tires do not get deformed by the curb other obstacles. If it is necessary to drive over curbs, speed humps or similar elevations, try to do so slowly and at an obtuse angle. Otherwise, the tires, particularly the sidewalls, may be damaged.

Regular checking of wheels and tires

WARNING
Damaged tires can cause tire inflation pressure loss. As a result, you could lose control of your vehicle. There is a risk of an accident.
Check the tires regularly for signs of damage and replace any damaged tires immediately.

Regularly check the wheels and tires of your vehicle for damage at least once a month, as well as after driving off-road or on rough roads. Damaged wheels can cause a loss of tire pressure. Pay particular attention to damage such as:

• cuts in the tires
• punctures
• tears in the tires
• bulges on tires
• deformation or severe corrosion on wheels

Regularly check the tire tread depth and the condition of the tread across the whole width of the tire (page 363). If necessary, turn the front wheels to full lock in order to inspect the inner side of the tire surface.
All wheels must have a valve cap to protect the valve against dirt and moisture. Do not mount anything onto the valve other than the standard valve cap or other valve caps approved by Mercedes-Benz for your vehicle. Do not use any other valve caps or systems, e.g. tire pressure monitoring systems.
Regularly check the pressure of all the tires particularly prior to long trips. Adjust the tire pressure as necessary (page 365).
