Note:
To signal turns while being towed with hazard warning
flasher in use, turn electronic key in steering lock to
position 2 and activate combination switch for left or
right turn signal in usual manner – only the selected
turn signal will operate.
Upon canceling the turn signal, the hazard warning
flasher will operate again.
Caution!
The vehicle must be towed with all 4 wheels off the
ground. If the vehicle is towed with the front axle raised,
the engine must be shut off (electronic key in steering
lock position 0 or 1). Otherwise, the ESP will
immediately be engaged and will apply the rear wheel
brakes. With the front wheels raised, the maximum
speed and towing distance are 30 mph and 30 miles.
Switch off the tow-away alarm, see page 41, and the
automatic center locking on page 35.Transmission selector lever, manually unlocking
In the case of power failure the transmission selector
lever can be manually unlocked, e.g. to tow the vehicle.
To do so, insert a pin (1), e.g. ball point pen, into the
covered opening below the position “D” of the shift
pattern. While pushing the pin down, move selector
lever from position “P”.
After removal of the pin from the opening, the cover will
not close fully. Only after moving the selector lever to
positions “D+” and “D–” does the cover return to its
closed position.

Engine cleaning
Prior to cleaning the engine compartment make sure to
protect electrical components and connectors from the
intrusion of water and cleaning agents.
Corrosion protection, such as MB Anticorrosion Wax
should be applied to the engine compartment after
every engine cleaning. Before applying, all control
linkage bushings and joints should be lubricated. The
poly-V-belt and all pulleys should be protected from any
wax.
Ve h i c l e w a s h i n g
Do not use hot water or wash your vehicle in direct
sunlight. Use only a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo.
Thoroughly spray the vehicle with a diffused jet of
water. Direct only a very weak spray towards the
ventilation intake. Use plenty of water and rinse the
sponge and chamois frequently.
Rinse with clear water and thoroughly wipe dry with a
chamois. Do not allow cleaning agents to dry on the
finish.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.
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.

Light alloy wheels
Mercedes-Benz approved Wheel Care should be used for
regular cleaning of the light alloy wheels.
If possible, clean wheels once a week with
Mercedes-Benz approved Wheel Care, using a soft
bristle brush and a strong spray of water.
Follow instructions on container.
Note:
Use only acid-free cleaning materials. The acid could
lead to corrosion.
Instrument cluster
Use a gentle dishwashing detergent or mild detergent
for delicate fabrics as a washing solution. Wipe with a
cloth moistened in lukewarm solution. Do not use
scouring agents.
Steering wheel and gear selector lever
Wipe with a damp cloth and dry thoroughly or clean
with Mercedes-Benz approved Leather Care.Cup holder
Use a gentle dishwashing detergent or mild detergent
for delicate fabrics as a washing solution. Wipe with a
cloth moistened in lukewarm solution. Do not use
scouring agents.
Seat belts
The webbing must not be treated with chemical
cleaning agents. Use only clear, lukewarm water and
soap. Do not dry the webbing at temperatures above
176
°F (80
°C) or in direct sunlight.
Headliner
Clean with soft bristle brush, or use a dry-shampoo
cleaner in case of excessive dirt.
Wa r n i n g !
Do not bleach or dye seat belts as this may severely
weaken them. In a crash they may not be able to
provide adequate protection.
