350 OperationVehicle careEngine cleaning
Prior to cleaning the engine compartment,
make sure to protect electrical compo-
nents and connectors from contact with
water and cleaning agents.
Corrosion protection, such as MB Anticor-
rosion Wax should be applied to the engine
compartment after every engine cleaning.
Before applying, all control linkage bush-
ings and joints should be lubricated. The
poly-V-belt and all pulleys should be pro-
tected from any wax.
Vehicle washing
Do not use hot water or wash your vehicle
in direct sunlight. Only use a mild car wash
detergent, such as Mercedes-Benz ap-
proved Car Shampoo.
Thoroughly spray the vehicle with a dif-
fused 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 dry
with a chamois. Do not allow cleaning
agents to dry on the finish.
Due to the width of the vehicle, fold in
exterior rear view mirrors prior to running
the vehicle through an automatic car wash
to prevent damage to the mirrors.
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the underbody, do not for-
get to clean the inner sides of the wheels.Ornamental moldings
For regular cleaning and care of very dirty
chrome-plated parts, use a chrome clean-
er.
Headlamps, tail lamps, side markers,
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 only use a soft, non-scratchy
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth
or sponge.
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of
water, and a SmartKey with
KEYLESS-GO* is in close proximity, i.e.
within approximately 3 ft (approxi-
mately 1 m), the vehicle could be inad-
vertently locked or unlocked.

Bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. See your autho-
rized Mercedes-Benz Center for headlamp
adjustment.
iIf the headlamps or front fog lamps are
fogged up on the inside as a result of
high humidity, driving the vehicle a dis-
tance with the lights on should clear up
the fogging.
iSubstitute bulbs will be brought into
use when lamps malfunction. Observe
the messages in the multifunction dis-
play (
page 392).
