Jump-starting
General notes If the vehicle battery is flat, the engine can be
started from another vehicle using jumper
cables. For this purpose, the vehicle has a
jump-starting connection point in the engine
compartment.
The additional battery in the engine
compartment is
not
suitable for jump-starting
operations. If your vehicle requires jump-
starting, or if you use it to jump-start another
vehicle, use the jump-starting connection
point in the engine compartment. G
Warning
Explosive oxyhydrogen is produced when
batteries are being

charged. When working on
batteries, always make sure that the work
area is well ventilated.
Keep flames and naked lights away from the
battery, and do not smoke.
Prevent the creation of sparks (e.g. when
disconnecting the batteries). Sparks can
ignite the oxyhydrogen gas and cause the
batteries to explode. You and others could be
seriously injured. G
Warning
Due to the gases which escape from batteries,
there is a risk of acid burns when jump-
starting a vehicle.

Do not lean over the battery
while the engine is being jump-started.
! Avoid repeated and lengthy starting
attempts.
Do not use a rapid-charging device to start
the engine. When jump-starting, observe the following
points:
R
jump-starting must only be performed
when the engine and catalytic converter
are cold.
R do not start the engine if the battery is
frozen. Let the battery thaw first.
R when jump-starting, use

only batteries with
the same nominal voltage and a similar
capacity.
R only use jump leads protected against
polarity reversal, with adequate cross-
section and with insulated battery terminal
clamps.
