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 the radio!
4. Open the hoods and locate the positive (+) and
negative ( ) terminal locations of the other vehicle.
Your vehicle has a remote positive (+) 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 behind
a red plastic cover near the engine accessory
drive bracket on the driver's side of the engine
compartment, below the alternator. To uncover
the remote positive (+) terminal, open the red
plastic cover.

The remote negative ( ) terminal is located on the
engine drive bracket on all V8 engines and is
marked GND (Ground).
On V6 engines the remote negative ( ) terminal is
located on a tab attached to the engine accessory
drive bracket and is marked GND (Ground).
CAUTION:
{
Using a match near a battery can cause battery
gas to explode. People have been hurt doing
this, and some have been blinded. Use a
flashlight if you need more light.
Be sure the battery has enough water. You do
not need to add water to the battery installed
in your new vehicle. But if a battery has filler
caps, be sure the right amount of fluid is there.
If it is low, add water to take care of that first.
If you do not, explosive gas could be present.
Battery fluid contains acid that can burn you.
Do not get it on you. If you accidentally get it
in your eyes or on your skin, flush the place
with water and get medical help immediately.
