Start the engine of the vehicle with the
flat battery and wait for 2 or 3 minutes
until the engine is running.
Removing the jump leads
Before you remove the jump leads,
switch off the dipped beam headlights if
they are switched on.
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.
When the engine is running, disconnect
the leads in reverse order to the details
given above.
Make sure the battery clamps have sufficient
metal-to-metal contact with the battery ter-
minals.
If the engine fails to start after about 10 sec-
onds, switch off the starter and try again after
about 1 minute.
