positive (+) under hood terminal of the discharged
battery and the other end to the positive (+) terminal
of the charged battery. Make sure the cable clamps
do not touch any other metal parts.
4. Clamp one end of the second jumper cable to the
grounded negative (–) terminal of the charged
battery and the final connection to the negative (–)
terminal (2) of the discharged battery.Important!
5. Start engine of the vehicle with the charged battery
and run at high idle. Make sure the cables are not
on or near pulleys, fans, or other parts that move
when the engine is started. Allow the discharged
battery to charge for a few minutes. Start engine of
the disabled vehicle in the usual manner.
6. After the engine has started, remove jumper cables
by exactly reversing the above installation
sequence, starting with the last connection made
first. When removing each clamp, make sure that it
does not touch any other metal while the other end
is still attached.

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.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.

Use a window cleaning solution on all glass surfaces. An
automotive glass cleaner is recommended.
Note:
For safety reasons, switch off wiper and remove
electronic key from steering lock before cleaning the
windshield, otherwise the wiper motor can suddenly
turn on and cause injury.
Wiper blade
Clean the wiper blade rubber with a clean cloth and
detergent solution.
Note:
For safety reasons, remove electronic key from steering
lock before cleaning the wiper blade, 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.
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.

Cup holder
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.
Hard plastic trim items
Pour Mercedes-Benz approved Interior Care onto soft
lint-free cloth and apply with light pressure.Headliner and shelf below rear window
Clean with soft bristle brush, or use a dry-shampoo
cleaner in case of excessive dirt.
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.
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.
