Be sure to use the following steps
to do it safely. Ignoring these steps
could result in costly damage to the
vehicle that would not be covered
by the warranty.
Trying to start the vehicle by
pushing or pulling it will not work,
and it could damage the vehicle.
Notice: 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 the vehicle.
Notice: If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
jumper cables in the correct
order, making sure that the
cables do not touch each other
or other metal.
1. The vehicle used to jump start
must have 12-volt battery with a
negative ground.
Notice: Only use a vehicle
that has a 12-volt system with
a negative ground for jump
starting. If the other vehicle
does not have a 12-volt system
with a negative ground, both
vehicles can be damaged.
Vehicle Care
2. The vehicles should be close
enough for the jumper cables to
reach, but the vehicles should
not be touching. Touching could
cause grounding and possible
electrical system damage.
Put both vehicles in P (Park)
and set the parking brake firmly.
3. Unplug accessories plugged
into the cigarette lighter or the
accessory power outlet. Turn off
the radio and all lamps that are
not needed. Turn off the ignition
on both vehicles.
4. Locate the positive (+) and
negative ( ) terminals on both
vehicles. Some vehicles have
remote jump starting terminals.
