1. Check the other vehicle. It must
have a 12-volt battery with a
negative ground system.
Caution
If the other vehicle does not have
a 12-volt system with a negative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.
2. Get the vehicles close enough
so the jump leads can reach, but
be sure the vehicles are not
touching each other. If they are,
it could cause a ground
connection you do not want. You
would not be able to start the
vehicle, and the bad grounding
could damage the electrical
systems.
To avoid the possibility of the
vehicles rolling, apply the
parking brake firmly on both
vehicles involved in the jump
start procedure. Put an
automatic transmission in
Vehicle Care
P (Park) or a manual gearbox in
Neutral before setting the
parking brakes.
Caution
If any accessories are left on or
plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting.
3. Turn off the ignition on both
vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the accessory
power outlet. Turn off the radio
and all lamps that are not
needed. This will avoid sparks
and help save both batteries.
And it could save the radio!
