Battery Care
damage to the vehicle, heed all warnings
and instructions of the jumper cable manufacturer.
The jumper cables must be long
enough so that the vehicles do not touch.
• Applying a higher voltage booster battery will
cause expensive damage to sensitive electronic
components, such as relays, and the
radio. Improper hook–up of jumper cables
or not following these procedures can damage
the alternator or cause serious damage
to both vehicles or yourself.
• Battery posts, terminals, and related accessories
contain lead and lead compounds,
chemicals known to the State of California to
cause cancer and reproductive harm. Wash
hands after handling.
CAUTION: Departures from these procedures
could also cause serious damage to both vehicles.
Improper use of a booster battery to start
a vehicle may cause an explosion.
To Jump Start Your Vehicle:
1. Wear eye protection and remove rings, metal watch
bands, and any other metal jewelry.
PART 8: MAINTENANCE AND SERVICE
2. Set the parking brakes. Place the transmissions of
both vehicles in Neutral. Do not let the vehicles touch
one another. Turn the ignition key to Off in the vehicle
with the discharged battery. Also turn off lights, heater,
and any other unnecessary electrical load.
3. If either battery has vent caps, remove them and check
the fluid level. If it is OK, replace the caps before going
further. If the level is low, add distilled water, and replace
the caps before proceeding. If no water is available,
remove the caps and cover the filler openings
with a cloth before proceeding. After jump starting the
vehicle, dispose of the cloth.
WARNING! If you do not cover the filler openings
on the battery, electrolyte could boil out
of the openings and hurt someone or damage
the vehicle. Replace caps securely if there
is enough fluid in the battery, or cover with
a cloth if no water is available and your fluid
is low.
4. Attach one end of a jumper cable to the dead battery’s
positive terminal. This will have a large red “+” or “P”
on the battery case, post, or clamp. Attach the other
end of the same cable to the positive terminal of the
good battery.
