Cleaning and care of the vehicle
Te ch n ica l

cluster displayPractical hintsCar careIndex Scratches, corrosive deposits, corrosion or damage due
to negligent or incorrect care cannot always be removed
or repaired with the car-care products recommended
here. In such cases it is best to seek aid at your
authorized Mercedes-Benz Center.
The following topics deal with the cleaning and care of
your vehicle and give important “how-to” information as
well as references to Mercedes-Benz approved car-care
products.
Additional information can be found in the booklet titled
“Vehicle Care Guide”.
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.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 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.
Plastic and rubber parts
Do not use oil or wax on these parts.

Tar stains
Quickly remove tar stains before they dry and become
more difficult to remove. A tar remover is
recommended.
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. Window cleaning
Use a window cleaning solution on all glass surfaces. An
automotive glass cleaner is recommended.
Wiper blade
Clean the wiper blade rubber with a clean cloth and
detergent solution. Instrument cluster
Use a gentle dishwashing detergent or mild detergent
for delicate fabrics as a washing solution. Wipe with a
cloth moistened in lukewarm solution. Do not use
scouring agents. Seat belts
The webbing must not be treated with chemical
cleaning agents. Use only clear, lukewarm water and
soap. Do not dry the webbing at temperatures above
176°F (80°C) or in direct sunlight.
Headliner
Clean with soft bristle brush, or use a dry-shampoo
cleaner in case of excessive dirt.
Wa r n i n g !
Do not bleach or dye seat belts as this may severely
weaken them. In a crash they may not be able to
provide adequate protection.

OrnamentalMoldings
For regular cleaning and care of very dirty chrome-
plated parts, use a chrome cleaner. Upholstery
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.
MB Tex Upholstery
Pour Mercedes-Benz approved Interior Care onto soft
lint-free cloth and apply with light pressure. Hard plastic trim items
Pour Mercedes-Benz approved Interior Care onto soft
lint-free cloth and apply with light pressure.Steering wheel and gear selector lever
Wipe with a damp cloth and dry thoroughly or clean
with Mercedes-Benz approved Leather Care.

Paintwork, painted body components
Mercedes-Benz approved Paint Care should be applied
when water drops on the paint surface do not “bead up”,
normally in 3 to 5 months, depending on climate and
washing detergent used.
Mercedes-Benz approved Paint Cleaner should be
applied if paint surface shows signs of dirt embedding
(i.e. loss of gloss).
Do not apply any of these products or wax if your
vehicle is parked in the sun or if the hood is still hot.
Use the appropriate MB-Touch-Up Stick for quick and
provisional repairs of minor paint damage (i.e. chips
from stones, vehicle doors etc.).Light alloy wheels
Mercedes-Benz approved Wheel Care should be used for
regular cleaning of the light alloy wheels.
If possible, clean wheels once a week with Mercedes-
Benz approved Wheel Care, using a soft bristle brush
and a strong spray of water.
Follow instructions on container.
Note:
Use only acid-free cleaning materials. The acid could
lead to corrosion.

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.
Wet cleaning:
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.
