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.
Ta r sta in s
Quickly remove tar stains before they dry and become
more difficult to remove. A tar remover is
recommended.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.
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.

automotive glass cleaner is recommended.

Using aftermarket seat covers or wearing clothing that
have the tendency to give off coloring (e.g. when wet
etc.) may cause the upholstery to become permanently
discolored. By lining the seats with a proper
intermediate cover, contact-discoloration will be
prevented.
Leather Upholstery
Wipe leather upholstery with a damp cloth and dry
thoroughly or clean with Mercedes-Benz approved
Leather Care. Exercise particular care when cleaning
perforated leather as its underside should not become
wet.

Soft top
Clean soft top with soft top raised and locked. Lower the
soft top into the storage compartment only if the soft top
is completely dry. If the soft top is kept in the storage
compartment for a lengthy period, raise it and air out
with the windows open about every 4 months.
Dry cleaning:
Brush top (always from front to rear) with a soft-bristled
brush.
We t c l e a n i n g :
Brush the dry top. Wash with a mild detergent and an
ample supply of lukewarm water by wiping with a soft-
bristled brush or sponge from front to rear. Then rinse
thoroughly with clear water.
If only parts of the top have been washed, wet the entire
top and allow it to air-dry before lowering it into the
storage compartment.
Do not use sharp-edged instruments for the removal of
ice and snow. Notes:
When you run the vehicle through an automatic car
wash, never use hot-wax for conservation.
Depending on the operation mode of the car wash, there
is the possibility of water drops entering the vehicle’s
interior.
Never use a power washer to clean the soft top, as you
may damage the soft top material.
Remove bird droppings immediately. The organic acid
damages the material and causes the soft top to leak.
In general, regular spraying or cleansing with clear
water is sufficient to keep the top clean.
Wash the top only when heavily soiled.
Light colored soft tops should be cleaned frequently to
prevent spots and dirt from setting in, which could stain
and discolor the soft top material permanently.
Caution!
Never use any gasoline, thinner, tar and stain removers,
glass cleaner, or similar organic solvents to clean the
soft top or wind screen. They will cause damage which
is not covered by the Mercedes-Benz Limited Warranty.
