5. 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, if your vehicle
has one. 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 and
diesel engines, and on the thermostat housing
on the 8.1L engine. On V8 engines it is
marked GND (Ground).
On V6 engines the remote negative (−)
terminal is located on a tab attached to the
engine accessory drive bracket where it
is marked GND (Ground).
See Engine Compartment Overview on
page 476 for more information on the location
of the remote positive (+) and remote
negative (−) terminals.
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.
