Notes on care
Regular and proper care maintains the value
of your vehicle.
i It
is advisable to use Mercedes-Benz care
products.
Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-
cialist workshop immediately, e.g. a
Mercedes-Benz Service Centre.
Repair damage caused by loose chippings
and remove the following substances imme-
diately, whilst avoiding rubbing too hard:
R Soak insect remains with insect remover
and rinse off afterwards.
R Soak bird droppings with water and rinse
off afterwards.
R Remove tree resin, oils, fuels and grease by
rubbing gently with a cloth soaked in clean-
ing or lighter fluid.
R Use silicone remover to remove wax.
R Use tar remover to remove tar stains. H
Environmental note
Dispose of empty packaging, cleaning
cloths and polishing wads in an environ-
mentally responsible manner.
! Do not affix:
R stickers
R films
R magnetic plates or similar
to painted surfaces, otherwise you could
damage the paintwork. Vehicle care
!

Do not park the vehicle for a long period
of time directly after cleaning, especially if
the wheels have just been cleaned with a
wheel cleaner. Wheel cleaners could cause
rapid corrosion of the brake discs and
brake pads/linings. After cleaning, park
the vehicle when it is at normal operating
temperature. Operation

Jump-starting
292 G
Risk of injury
There is a risk of acid burns when jump-
starting a vehicle due to the gases which
escape from the battery. Do not lean over
the battery while the engine is being jump-
started. G
Risk of explosion
Gases escaping from the battery during
jump-starting may cause minor explosions.
Avoid creating sparks. Keep naked flames
away from the battery, and do not smoke.
Comply with safety precautions and take
protective measures when handling batter-
ies. You will find these under “Battery” in
the index.
X Make sure that the two vehicles do not
touch.
X Depress the parking brake.
X Move the selector lever to P.
X Switch off all electrical consumers.1 Positive terminal of your vehicle's battery
2 Positive terminal of donor battery
3 Negative terminal of donor battery
4 Connection for suitable earth point on the
vehicle
X Connect positive contact on your vehi-
cle 1 to positive terminal of the donor
battery 2 using the jump lead, connecting
the jump lead to your own battery first.
X Start the engine of the donor vehicle and
run it at idling speed.
X Connect the negative terminal of the donor
battery 3 and the earth contact on your
vehicle 4 using the jump lead, connecting
the jump lead to the donor battery first.

Electrical consumers can be switched on
again. Do not switch the lights on however,
as this will overload the battery.

earthing point 4 and negative termi-
nal 3 first, then from the positive termi-
nals 1 and 2, each time disconnecting
from the battery on your own vehicle first.
