3. 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 transmission
in PARK (P) or a manual transmission in NEUTRAL
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.
4. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter and accessory power outlets. 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!
5. Open the hoods and locate the positive (+) and
negative (−) terminal locations of the other vehicle.
Your vehicle has a remote positive (+) 12-volt
jump starting terminal and a remote negative (−)
jump starting terminal. You should always use these
remote terminals instead of the terminals on the
battery.
The remote positive (+) terminal is located under
a red plastic cover near the center of the engine
compartment. See Engine Compartment Overview
on page 5-4. To access the remote positive (+)
terminal, open the red plastic cover.
