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. If you have a
four-wheel-drive vehicle, be sure the transfer
case is in a drive gear, not in NEUTRAL.
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 or 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
the radio!
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).
