Jump leads
Jump leads must comply with the standard DIN 72553 (see manufacturer's
documentation). The wire cross section must be at least 25 mm
2
for petrol
engines and at least 35 mm
2
for diesel engines.
Note
• The vehicles must not touch each other, otherwise electricity could flow as
soon as the positive terminals are connected.
• The discharged battery must be properly connected to the vehicle elec-
trical system.
How to jump start: description
In ⇒ fig. 163 the flat battery is represented and in the
charged battery is represented.
Jump lead terminal connections
– Switch off the ignition in both vehicles ⇒ .
1. Connect one end of the red jump lead to the positive ⇒ fig. 163
terminal of the vehicle with the flat battery ⇒ .
2. Connect the other end of the red jump lead to the positive
terminal in the vehicle providing assistance.
3. Connect one end of the black jump lead to the negative terminal
on the battery of the vehicle providing assistance.
4. Connect the other end of the black jump lead to a solid metal
component which is bolted on to the engine block, or onto the
engine block itself of the vehicle with the flat battery. Do not
connect it to a point near the battery ⇒ .
5. Position the leads in such a way that they cannot come into
contact with any moving parts in the engine compartment.
Starting
6. Start the engine of the vehicle with the boosting battery and let
it run at idling speed.
7. Start the engine of the car with the flat battery and wait one or
two minutes until the engine is “running”.
Removing the jump leads
8. Before you remove the jump leads, switch off the headlights (if
they are switched on).
9. Turn on the heater blower and rear window heater in the vehicle
with the flat battery. This helps minimise voltage peaks which are
generated when the leads are disconnected.
