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 en-
gine 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
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the vehicle underbody, do
not forget to clean the inner sides of the
wheels.Hand-wash
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 clean water and thoroughly
dry with a chamois.
Do not allow cleaning agents to dry on
the finish.Automatic car wash
You can have your car washed in an auto-
matic car wash from the start. Automatic
car washes without brushes are prefera-
ble.
If the vehicle is very dirty, prewash it be-
fore running it through the automatic car
wash.
!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
mirrors.
Make sure that the windshield wiper
switch is set to0 (
page 53). Other-
wise, the rain sensor could activate and
cause the wipers to move unintention-
ally. This may lead to vehicle damage.

346 OperationVehicle careLight alloy wheels
If possible, clean wheels once a week.
Use Mercedes-Benz approved Wheel
Care, a soft bristle brush and a strong
spray of water for cleaning the light al-
loy wheels.Plastic and rubber parts
Use a gentle dishwashing detergent or
mild detergent for delicate fabrics as a

Instrument cluster and cup holders

mild detergent for delicate fabrics as a
washing solution.

!Only use acid-free cleaning materials.
Acid may cause corrosion or damage
the clear coat.
!The vehicle should not be parked for an
extended period of time immediately
after it has been cleaned, especially not
after the wheel rims have been cleaned
with wheel rim cleaner. Wheel rim
cleaners can lead to increased corro-
sion of the brake disks and brake pads.
Therefore, the vehicle’s brake system
should always be warmed-up before it
is parked after cleaning. To do so,
please drive your vehicle for several
minutes to allow the brakes to dry.
When applying Mercedes-Benz ap-
proved Tire Care and Mercedes-Benz
approved Wheel Care products, take
care not to spray them on the brake
disks.

ing agents.

Using aftermarket seat covers or wearing
clothing that have the tendency to give off
coloring (e.g. when wet, etc.) may cause

intermediate cover, contact-discoloration
will be prevented.
