External Power Supply, Emergency
starting with jumper cables
If the battery is flat, the battery of another vehicle
can be used for starting or as an external power
supply with the help of jump leads.
Both batteries must be 12 V batteries. The
capacity (Ah) of the donor battery must not be
substantially less than that of the flat battery.
The flat battery must be connected correctly to
the vehicle's electrical system.

Jumper cable hazards
WARNING
A short circuit may be caused if unsuitable jumper
cables are used or if jumper cable starting is not
performed properly. Such short circuits can
cause a fire.
f
Use only standard jumper cables with sufficient
cross section and completely insulated
alligator clips. Follow the instructions provided
by the jumper cable manufacturer.
f
Route the jumper cables so that they cannot
be caught by moving parts in the engine
compartment.
The jumper cables must be long enough so
that neither vehicles nor cables touch another.
f
The vehicles must not touch, otherwise current
might flow as soon as the positive terminals
are connected.
f
Ensure that tools or conductive jewelry (rings,
chains, watch straps) do not come into contact
with the positive jumper cable, the positive
battery post or live parts of the vehicle.
f
Improper hook-up of jumper cables can ruin
the alternator.
h
Battery acid leakage
WARNING
f
Do not lean over the battery due to danger of
chemical burns from leaking acid.
