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.
NOTICE:
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).

3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory power outlets. Turn off all lamps
that aren't needed as well as radios. This will avoid
sparks and help save both batteries. In addition, 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.
4. Open the hoods and locate the battery on the other
vehicle and the remote positive (+) terminal, located
on the passenger's side of the engine, on your
vehicle. (You will not see the battery under the hood
of your vehicle, since it is located under the rear seat
on the passenger's side.) Find the positive (+)
-
and negative ( ) terminals on the battery in the
other vehicle.
You do not need to access your battery for jump
starting. The remote positive (+) terminal, located on
the driver's side of the engine compartment, is for
this purpose.
