Vehicle care
Vehicle washing
Do not use hot water or wash your vehicle
in direct sunlight. Use only 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 out-
side 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
cleaner.
Headlamps, tail lamps, 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 use only a soft, non-scratchy
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth
or sponge.
Wiper blades
Clean the wiper blade inserts with a clean
cloth and detergent solution.Window cleaning
Use a window cleaning solution on all glass
surfaces. An automotive glass cleaner is
recommended.
iFor safety reasons, switch off wipers
and remove key from starter switch be-
fore cleaning the wiper blades, other-
wise the wiper motor can suddenly turn
on and cause injury.!Fold the windshield wiper arms back
onto the windshield before turning the
key in the starter switch.iFor safety reasons, switch off wipers
and remove key from starter switch be-
fore cleaning the windshield, otherwise
