Vehicle care
Engine 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 Anticor-
rosion 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.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.
Due to the width of the vehicle, fold in
outside 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
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, 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
attempt to wipe dirty lenses with a dry
cloth or sponge.

intermediate cover, contact-discoloration
will be prevented.
