1. On the vehicle to be jump-started,
remove the battery cover and any ter-
minal boots.
2. Inspect the battery for any signs of
electrolyte leaks, loose terminals, or
bulging sides. Leaking or bulging bat-
tery cases may indicate a frozen or
shorted battery.
3. Inspect the vehicle to be used for
jump-starting to determine if voltage
and ground polarity are compatible.
The vehicle must have a 12-volt DC,
negative ground electrical system.
4. Move the vehicle to be used for the
jump-start close enough to ensure the
jumper cables easily reach; then shift
into neutral, set and lock the brakes,
shut off all electrical accessories, and
turn the ignition switch OFF.
NOTE: Make sure all switches on
the vehicle to be jump-started are
turned OFF.
5. Disconnect all external accessories
such as cell phones, GPS units, and
radios on both vehicles.
6. Attach one clamp of the positive (red)
jumper cable to the positive (+) termi-
nal (1) of the dead battery (C) being
careful not to touch any metal with the
other clamp; then attach the other
clamp of the positive (red) jumper
cable to the positive (+) terminal (2) of
the good battery (B).

NOTE: Some jumper cables may
be the same color but the clamps or
ends will be color-coded red and
black.
7. Attach one clamp of the negative
(black) jumper cable to the negative (-)
terminal (3) of the good battery (B);
then attach the other clamp of the nega-
tive (black) jumper cable (4) to an
unpainted metal surface (A) on the
engine or frame well away from the
dead battery and fuel system compo-
nents.
8. Stand well away from the dead bat-
tery and start the vehicle with the
good battery. Allow the vehicle to run
for several minutes applying some
charge to the dead battery.
! WARNING
Any time service is performed on a
battery, the following must be
observed: keep sparks, open flame,
cigarettes, or any other flame away.
Always wear safety glasses. Protect
skin and clothing when handling a
battery. When servicing battery in
enclosed space, keep the area well-
ventilated. Make sure battery venting
is not obstructed.
! WARNING
If any of these conditions exist, DO
NOT attempt a jump-start, boost, or
charge the battery. An explosion
could occur causing serious injury.
CAUTION
Always make sure the electrical sys-
tems are of the same voltage and
ground polarity prior to connecting
jumper cables. If not, severe electri-
cal damage may occur.
CAUTION
Failure to disconnect electronic
accessories during jump-starting
may cause system damage due to
power spikes.
! WARNING
Never make the final connection to a
battery as a spark could ignite hydro-
gen gases causing an explosion of
the battery resulting in acid burns or
blindness.
