3. Turn off the ignition on both
vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the accessory
power outlets. Turn off the radio

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 or the remote
positive (+) and remote
negative ( ) terminals of the
other vehicle. Then locate the
remote positive (+) location on
your vehicle. See
for locations of the
terminals.
Your vehicle has a remote
negative ( ) ground location, as
shown in the illustration. It is on
the left side of the engine
compartment. See
. You should always
use this remote ground location,
instead of the terminal on the
battery.
An electric fan can start up even
when the engine is not running
and can injure you. Keep hands,
clothing and tools away from any
underhood electric fan.
Using an open flame 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.
