When towing the vehicle, please, note the following:
With the automatic central locking activated and the
electronic key in starter switch position 2 (vehicles with
KEYLESS-GO: in “On” position, see page 232), the
vehicle doors lock if the left front wheel as well as the
right rear wheel are turning at vehicle speeds of
approximately 9 mph (15 km / h) or more.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking. See
“VEHICLE” under “Individual settings” on page 146.
Towing of the vehicle should only be done using the
properly installed towing eye bolt. Never attach tow
cable, tow rope or tow rod to vehicle chassis, frame
or suspension parts.
Note:
The selector lever will remain locked in position “P” and
the electronic key cannot be turned in the starter switch
if the battery is disconnected or discharged. See battery
on page 357 or jump starting on page 359.
Wa r n i n g !
Prior to towing the vehicle with all wheels on the
ground, make certain that the electronic key is in
starter switch position 2. The maximum towing
speed and distance with the vehicle on the ground
is 30 mph (50 km/h) and 30 miles (50 km).If the electronic key is left in the starter switch
position 0 for an extended period of time, it can no
longer be turned in the switch. To unlock, remove
electronic key from starter switch and reinsert.

cluster displayPractical hintsCar careIndex Scratches, corrosive deposits, corrosion or damage due
to negligent or incorrect care cannot always be removed
or repaired with the car-care products recommended
here. In such cases it is best to seek aid at your
authorized Mercedes-Benz Center.
The following topics deal with the cleaning and care of
your vehicle and give important “how-to” information as
well as references to Mercedes-Benz approved car-care
products.
Additional information can be found in the booklet titled
“Vehicle Car Guide”.Power washer
When using a power washer for cleaning the vehicle
always observe manufacturers’ operating instructions.
Note:
Vehicles with KEYLESS-GO:
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.
Caution!
Never use a round nozzle to power wash tires. The
intense jet of water can result in damage to the tire.
Always replace a damaged tire.
Always keep the jet of water moving across the surface.
Do not aim directly at electrical parts, electrical
connectors, seals, or other rubber parts.

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.

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.
