Starting using another
battery
If the battery in your vehicle is fl at,
the engine can be started using a
slave battery (external or in another
vehicle) and jump leads.
First ensure that the slave
battery has a nominal volt-
age of 12 V and a capac-
ity at least equal to that of the fl at
battery.
Do not try to start the engine by
connecting a battery charger.
Do not disconnect the (+) terminal
when the engine is running.

slave battery B .
Connect one end of the green or
black lead to the (-) terminal of
the slave battery B (or the earth
point on the slave vehicle).
Connect the other end to the
earth point C on the broken-
down vehicle.
Start the engine on the slave ve-
hicle and leave the engine run-
ning for a few minutes.
Operate the starter on the bro-
ken-down vehicle and leave the

If the engine does not start
straight away, switch off the ig-
nition and wait a few moments
before trying again.
With the engine idling, discon-
nect the jump leads in reverse
