376 OperationVehicle careEngine cleaning
Prior to cleaning the engine compartment
make sure to protect electrical compo-
nents 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 en-
gine cleaning. Before applying, all control
linkage bushings and joints should be lu-
bricated. The poly-V-belt and all pulleys
should be protected 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
approved 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.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.
!Due to the width of the vehicle, fold in
exterior rear view mirrors prior to run-
ning the vehicle through an automatic
car wash to prevent damage to the mir-
rors.iAfter running the vehicle through an au-
tomatic car wash, wipe any wax off of
the windshield (
page 378) and the
wiper blade inserts (page 378). This
will prevent smears and reduce wiping
noise which can be caused by residual
wax on the windshield.
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.
