Jump starting
Introduction
For technic
al reasons, your vehicle must
not be tow-started. If the engine fails to
start because the 12-volt vehicle battery is
flat, the discharged battery can be connec-
ted to the 12-volt battery of another vehicle
to start the engine.
In vehicles with a 12-volt vehicle battery in
the vehicle interior, the jump leads must al-
ways be connected to the jump-start con-
nection points in the bonnet space.
WARNING
Using the jump leads incorrectly or com-
pleting the jump start proc
edure incor-
rectly can cause the 12-volt vehicle bat-
tery to explode, which can lead to serious
or fatal injuries.
·
Always read and observe the warnings
and safety information before carrying
out any kind of work on the 12-volt vehi-
cle battery → page 341.
·
Never confuse the positive battery ter-
minal with the negative battery termi-
nal or connect the jump leads incorrect-
ly.
·
Never jump start a vehicle with a frozen
or thawed 12-volt vehicle battery.
WARNING
A highly explosive mixture of gases is pro-
duc
ed at the 12-volt vehicle battery during
jump starting. The explosive gas could be
ignited by sparks. This can result in an ex-
plosion and serious or fatal injuries.
·
Always keep fire, sparks, naked flames
and lit cigarettes away from the 12-volt
vehicle battery.
·
Avoid electrostatic discharge in the vi-
cinity of the 12-volt vehicle battery.
