programmed to assist the driver during parking 
maneuvers (e.g. to observe the curb or other objects

mirror to view the curb.
3. Push the memory button “M” (4).

two electronic main keys or each of the KEYLESS-GO-
cards (vehicles with KEYLESS-GO).

cluster displayPractical hintsCar careIndex Due to the width of the vehicle, prior to running the 
vehicle through an automatic car wash, fold back the 
outside mirrors to prevent them from getting damaged.
In the winter, thoroughly remove all traces of road salt 
as soon as possible.
When washing the underbody, do not forget to clean the 
inner sides of the wheels.
Note:
Ve h i c l e s  w i t h  K EY L E S S - G O :  
If a door handle is hit by a strong jet of water, and a 
KEYLESS-GO-card is in close proximity, approx. 3 ft. 
(approx. 1m), the vehicle could be inadvertently locked 
or unlocked.Ornamental moldings
For regular cleaning and care of very dirty chrome-
plated parts, use a chrome cleaner.
Headlamps, taillamps, turn signal lenses
Use a mild car wash detergent, such as Mercedes-Benz 
approved Car Shampoo, with plenty of water.
To prevent scratches, never apply strong force and use 
only a soft, non-scratchy cloth when cleaning the lenses. 
Do not attempt to wipe dirty lenses with a dry cloth or 
sponge.
