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.

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 catalyticconverter 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.This 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.
