Jump-starting
G
WARNING
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
WARNING
Gases escaping from the battery during jump-starting may cause minor explosions. Avoid cre-
ating sparks. Keep naked flames away from the battery, and do not smoke.
Comply with safety precautions when handling batteries. You will find these under "Battery (vehi-
cle)" in the index. G
WARNING
Non-combusted fuel can collect in the exhaust system and ignite. There is a risk of fire. Avoid
repeated and lengthy starting attempts.
! Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
Do not use a rapid charging device to start the vehicle. If your vehicle's battery is discharged,
the engine can be jump-started from another vehicle or from a second battery using jump
leads. Observe the following points:
R the battery is not accessible in all vehicles. if the other vehicle's battery is not accessible,
jump-start the vehicle using a second battery or ajump-starting device.
R you may only jump-start the vehicle when the engine and catalyti cconverter are cold.
R do not start the engine if the battery is frozen. let the battery thaw first.
R jump-starting may only be performed from batteries with a nominal voltage of 12 V.
R only use jump leads that have a sufficient cross-section and insulated terminal clamps.
R If the battery is fully discharged, leave the battery that is being used to jump-start connected
for a few minutes before attempting to start.T his charges the empty battery a little.
R Make sure that the two vehicles do not touch.
Make sure that:
R the jump leads are not damaged.
R bare parts of the terminal clamp do not come into contact with other metal parts while the
jump leads are connected to the battery.
R the jump leads cannot come into contact with parts such as the V-belt pulley or the fan.
These parts move when the engine is started and while it is running.

operating.
Blown fuses must be replace dwith fuses of
the same rating, which you can recognise by
the colour and fuse rating. The fuse ratings
are listed in the fuse allocation chart.
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
! Only use fuses that have been approved
for Mercedes-Ben zvehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or sys-
tems could be damaged. Before replacing a fuse
