Emergency Starting With Jumper Cables - Porsche 911 GT3 Owner's Manual

Emergency Starting with Jumper
Cables
If the battery is discharged, e.g. in winter or after
the car has been parked for a long time, the bat-
tery of another car can be used for starting with
the help of jumper cables.
Make sure the voltage of both batteries is the
same.
The capacity (Ampere hours, Ah) of the booster
battery must not be substantially less than that of
the discharged battery.
The discharged battery must be correctly con-
nected to the vehicle's electrical system.

Practical Tips, Emergency Service
A
Warning!
Risk of damage and serious personal injury
due to short circuit.
Use only jumper cables of adequate diameter
I>
cross-section and fitted with completely insu-
lated alligator clips.
Follow all warnings and instructions of the
I>
jumper cable manufacturer.
When connecting jumper cables, make sure
I>
that they cannot get caught in any moving
parts in the engine compartment.
The jumper cables must be long enough so
that neither vehicles nor cables touch another.
The vehicles must not be in contact, otherwise
I>
current might flow as soon as the positive ter-
minals are connected.
The cable clamps must not be allowed to con-
I>
tact each other when one end of the jumper ca-
bles are connected to a battery.
Ensure that tools or conductive jewellery
I>
(rings, chains, watch straps) do not come into
contact with live parts of the vehicle.
Improper hook-up of jumper cables can ruin
I>
the alternator.
Danger of caustic burns.
Do not lean over the battery.
I>
Danger of gas explosion.
Improper use of booster battery to start a
I>
vehicle may cause an explosion, resulting in
severe personal injuries.
Keep sources of ignition away from the bat-
I>
tery, e.g. open flame, burning cigarettes or
sparking due to cable contact or welding work.
A discharged battery can freeze even at
I>
WFj-lOoC.
Before connecting Jumper cables, a frozen bat-
tery must be thawed out.
