Exterior lamps
Headlamp adjustment
Correct headlamp adjustment is extremely important.
Check and readjust headlamps at regular intervals and
when a bulb has been replaced.Replacing bulbs
Notes:
To prevent a possible electrical short circuit, switch off
lamp prior to replacing a bulb.
When replacing bulbs, install only 12 volt bulbs with
the specified watt rating.
When replacing halogen bulbs do not touch glass
portion of bulb with bare hands. Use plain paper or a
clean cloth.
If the newly installed bulb does not light up, switch the
lamp off and on again. If the bulb still does not light up,
have the system checked at an authorized
Mercedes-Benz Center.
Wa r n i n g !
Bulbs and bulb holders can be very hot. Allow the
lamp to cool down before changing a bulb.
Halogen lamps contain pressurized gas. A bulb can
explode if you:
• touch or move it when hot,
•drop the bulb,
•scratch the bulb.Wear eye and hand protection.
Wa r n i n g !
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the lamp
and its components. We recommend that you have
such work done by a qualified technician.

Tar stains
Quickly remove tar stains before they dry and become
more difficult to remove. A tar remover is
recommended.
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.).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.

Window cleaning
Use a window cleaning solution on all glass surfaces. An
automotive glass cleaner is recommended.
Note:
For safety reasons, switch off wipers and remove
electronic key from starter switch before cleaning the
windshield, otherwise the wiper motor can suddenly
turn on and cause injury.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.

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 and shelf below rear window
Clean with soft bristle brush, or use a dry-shampoo
cleaner in case of excessive dirt.Leather 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.
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.
Hard plastic trim items
Pour Mercedes-Benz approved Interior Care onto soft
lint-free cloth and apply with light pressure.
Plastic and rubber parts
Do not use oil or wax on these parts.
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.
