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 start procedure. Put an automatic
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brake.
If you have a four
-wheel-drive vehicle, be sure the
transfer case is not in NEUTRAL (N).
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory power outlets (if equipped). Turn
off the radio and all lamps that aren't needed. This
will avoid sparks and help to save both batteries.
And it could save your radio!
4. Open both hoods and locate the batteries. Find the
positive (+) and negative (
-) terminals on each
battery. Your vehicle has a remote negative (
-) jump
starting terminal. You should always use this remote
terminal instead of the terminal on the battery. The
remote negative (
-) terminal is located on the front
engine lift bracket and is marked ªGND.º See
ªEngine Compartment Overviewº in the Index for
more information on location.
