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 connected to the vehicle's elec-
trical system.
f Please observe the chapter "BATTERY" on
Page 312.
Note

f Use only jumper cables of adequate diameter
cross-section and fitted with completely insu-
lated alligator clips.
f Follow all warnings and instructions of the
jumper cable manufacturer.
f When connecting jumper cables, make sure
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.
f The vehicles must not be in contact, otherwise
current might flow as soon as the positive ter-
minals are connected.
f The cable clamps must not be allowed to con-
tact each other when one end of the jumper ca-
bles are connected to a battery.
f Carefully ensure that tools or conductive jewel-
ery (rings, chains, watch straps) do not come
into contact with the positive jumper cable or
the positive battery post.
f Improper hook-up of jumper cables can ruin
the alternator.
Risk of caustic burns from escaping acid.
f Do not lean over the battery.

f Keep sources of ignition away from the bat-
tery, e.g. open flame, burning cigarettes or

14°F/ 10°C. Before connecting jumper ca-
bles, a frozen battery must be thawed out.
