2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren't touching
each other. If they are, it could cause a ground
connection you don't want. You wouldn't 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 starting procedure. Put an
automatic transaxle in PARK (P) or a manual
transaxle in NEUTRAL.
3. Turn off the ignition on both vehicles. Turn off all
lamps that aren't needed, and radios. This will avoid
sparks and help save both batteries. And it could
save your radio.
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.

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.
4. Find the positive (+) and negative (
on the battery of the other vehicle. Your vehicle
has a remote positive (+) jump starting terminal.
The terminal is on the same side of the engine
compartment as your battery. You should always
use the remote positive (+) terminal instead of the
positive (+) terminal on your battery. The battery
is located on the passenger's side of the engine
compartment underneath the diagonal cross brace.
See "Engine Compartment Overview" in the Index
for more information on location.
