tow-start a vehicle if charging the battery

gine, do not tow it more than a short dis-

tance, otherwise unburned fuel can enter the

catalytic converter.

have the same voltage as the flat battery

(12V) and approximately the same capaci-

ty (see imprint on battery). Failure to com-

ply could result in an explosion.

Note

The vehicles must not touch each other,

otherwise electricity could flow as soon as

the positive terminals are connected.

●

Never use jump leads when one of the

batteries is frozen. Danger of explosion!

Even after the battery has thawed, battery

acid could leak and cause chemical burns.

If a battery freezes, it should be replaced.

Removing the jump leads

9. Before you remove the jump leads,

switch off the dipped beam headlights if

they are switched on.

10. Turn on the heater blower and heated

rear window in the vehicle with the flat

battery. This helps minimise voltage

peaks which are generated when the

leads are disconnected.

●

Keep sparks, flames and lighted ciga-

rettes away from batteries, danger of ex-

plosion. Failure to comply could result in an

explosion.

●

Observe the instructions provided by the

manufacturer of the jump leads.

●

Do not connect the negative cable from

the other vehicle directly to the negative

terminal of the flat battery. The gas emit-

ted from the battery could be ignited by

sparks. Danger of explosion.

11. When the engine is running, disconnect

the leads in reverse order to the details

given above.
