Vehicle care
Engine cleaning
Prior to cleaning the engine compartment,
make sure to protect electrical
components and connectors from contact
with 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.
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
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 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
automatic car wash from the start.
Automatic car washes without brushes are
preferable.
To protect the filter system, switch the
climate control or automatic climate
control to air recirculation mode, see
“Air recirculation” (
page 165) for
climate control or (
page 175) for
automatic climate control.
If the vehicle is very dirty, prewash it
before running it through the automatic
car wash.
!Do not use scouring agents on these parts.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the vehicle.
Do not attempt to wipe the surface with a dry
cloth or sponge.
Otherwise you nay scratch or damage the paint.
!Do not clean your vehicle in an automatic
touchless car wash which uses caustic spray.
Otherwise the caustic spray will damage the
paint or ornamental moldings.
