Engine cleaning
Prior to cleaning the engine compartment make sure to
protect electrical components 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 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.
Ve h i c l e w a s h i n g
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 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 clear water and thoroughly wipe dry with a
chamois. Do not allow cleaning agents to dry on the
finish.Due to the width of the vehicle, prior to running the
vehicle through an automatic car wash, fold back the
outside mirrors to prevent them from getting damaged.
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, taillamps, 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 attempt to wipe dirty lenses with a dry cloth or
sponge.
