2. Get the vehicles close enough so the jumper cables
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 your vehicle, and the bad grounding
could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. Put an automatic
transaxle in PARK (P) or a manual transaxle in
NEUTRAL (N) before setting the parking brake.
Notice: If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered
by your warranty. Always turn off your radio and
other accessories when jump starting your vehicle.
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 your radio!
4. Open the hood on the other vehicle and locate the
positive (+) and negative ( ) terminal locations on
that vehicle.

To uncover the remote positive (+) terminal, press
the tab at the bottom of the fuse block and lift
the cover up. Always use the remote positive (+)
terminal instead of the positive (+) terminal on
the battery.
CAUTION:
{
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from any
underhood electric fan.
You will not use your
vehicle's battery for jump
starting. It has a remote
positive (+) jump starting
terminal, located on
the underhood fuse block,
for that purpose. See
Engine Compartment
