Boost starting from another vehicle
Using booster cables
WARNING: Ensure that both
batteries are 12 V and that the
booster cables have insulated
clamps and are approved for use
with 12 V batteries.
WARNING: Do not connect positive
(+) terminals to negative (-)
terminals.
WARNING: Take care when working
near rotating parts of the engine.
Ensure cables are kept well clear.
NOTE: Do not use a 24 V booster start
system. These produce excessive
voltage and can damage the vehicle’s
electrical system.
NOTE: It is not possible to push or tow
start a vehicle with a discharged
battery.
NOTE: If using a donor vehicle, please
allow it to have the engine running for
a minimum of 2 minutes before trying
to start the disabled vehicle.
Boosting procedure
1. If a donor vehicle is to be used, park it so
that the battery location is adjacent,
but ensure the two vehicles do not
touch.
2. Apply the parking brake and ensure
that the transmission of both vehicles is
set in neutral (or park for vehicles with
automatic transmission).
3. Switch off the ignition and all electrical
equipment in both vehicles.
4. Open the luggage compartment and
remove any items stowed inside.
5. Remove the 2 quarter turn screws
securing the top of the battery access
cover.
