Advice
CAUTION
To avoid considerable damage to the vehicle
electrical system, note the following careful-
ly:
●
If the jump leads are incorrectly connected,
this could result in a short circuit.
●
The vehicles must not touch each other,
otherwise electricity could flow as soon as
the positive terminals are connected.

without Start-Stop system.

with Start-Stop system.
Jump lead terminal connections
1. Switch off the ignition of both vehicles
››› .
2. Connect one end of the red
jump lead to
the po

.
6. Position the leads in such a way that they
cannot come into contact with any moving
parts in the engine compartment.
Starting
7. Start the engine of the vehicle with the
boosting battery and let it run at idling
speed.
8. Start the engine of the vehicle with the flat
battery and wait 2 or 3 minutes until the
engine is “running”.
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
w
indo
w in the vehicle with the flat battery.
This helps minimise voltage peaks which
are generated when the leads are discon-
nected.
11.When the engine is running, disconnect
the leads in reverse order to the details
given above.
