CAUTION
Applying a higher voltage booster bat-
tery will cause expensive damage to
sensitive electronic components, such
as relays, and the radio. Failure to
comply may result in equipment dam-
age.
CAUTION
Improper hook-up of jumper cables or
not following these procedures can
damage the alternator or cause seri-
ous damage to both vehicles.
WARNING
Heed all warnings and instructions of
the jumper cable manufacturer. Failure
to comply may result in death, person-
al injury, equipment or property dam-
age.
1. Remove any jewelry that may come in
contact with the battery terminals.
2. Select a jumper cable that is long
enough to attach to both vehicles in a
way that ensures neither vehicle
touches each other.
3. Position the two vehicles together, but
do not allow them to touch.
4. Turn OFF all lights, heater, radio, and
any other accessory on both vehicles.
5. Set the parking brake (please refer to
Parking for specific instructions on
how to set the parking brake for this
vehicle).
6. Shift the transmission into park
position or neutral for manual
transmissions.
7. If either vehicle is equipped with
battery disconnects ensure they are in
the OFF position prior to connecting
the two vehicles.
8. Attach one end of a jumper cable to
the positive (+) terminal of the
discharged (dead) battery. This will
have a large red + or P on the battery
case, post, or clamp.
9. Attach the other end of the same
cable to the positive (+) terminal of the
good (booster) battery.
10. Attach the remaining jumper cable
FIRST to the negative (-) terminal
(black or N) of the good battery.
11. Attach the other end of the negative
cable to a bare metal part not bolted to
the engine block.
NOTE
Always connect positive (+) to
positive (+) and negative (-) to
negative (-).
12. If either vehicle is equipped with
battery disconnects, ensure that they
are in the ON position.
13. Start the vehicle that has the good
battery first. Let it run for 5 minutes.
