2004 JEEP WRANGLER jump cable

²Always park on a firm, level surface as far from the
edge of the roadway as possible before raising the
vehicle.
²Apply the parking brake firmly before jacking.
²Always block the wheel diagonally opposite the wheel
being raised.
²Do not raise the vehicle higher than is necessary to
remove the tire.
²Never start the engine with the vehicle on a jack.
²Do not let passengers sit in the vehicle when it is on a
jack.
²Do not get under the vehicle when it is on a jack.
²Failure to follow the ªTire Changing Procedureº may
result in personal injury or damage to your vehicle.
²Only use the jack in the positions indicated.
JUMP STARTING
WARNING!
To prevent personal injury or damage to clothing, do
not allow battery fluid to contact eyes, skin, or
fabrics. Do not lean over a battery when connecting
jumper cables or allow cable clamps to touch each
other. Keep open flames or sparks away from battery
vent holes. Always wear eye protection when work-
ing with batteries. Do not use a booster battery or
any other booster source that has a greater than
12±volt system, i.e. do not use a 24±volt power
source.
Your vehicle is equipped with a 12±volt battery. If it
becomes necessary to use a booster battery, with jumper
cables, to start the vehicle's engine because it's battery is
discharged, the following procedure should be followed:
216 WHAT TO DO IN EMERGENCIES

Set the parking brake, place an automatic transmission in
P (Park) (or N (Neutral) for a manual transmission). Turn
off lights, heater, and other electrical loads. Observe
charge indicator in the battery. If indicator is light or
yellow, replace the battery.
CAUTION!
Use the ªJump Startingº procedure only when the
charge indicator is dark in the center. Do not attempt
jump starting when the battery charge indicator is
bright or yellow. If the charge indicator is dark and
has a green dot in the center, failure to start is not
due to a discharged battery and the cranking system
should be checked.
1. Attach one end of the jumper cable to the positive
terminal of the discharged battery and the other end of
the same cable to the positive terminal of the booster
battery.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
2. Connect one end of the other jumper cable to the
negative terminal of the booster battery. Connect the
other end of the jumper cable to a good ground on the
vehicle with the discharged battery. Make sure a good
connection is made, free of dirt and grease.

WARNING!
²Do not connect the cable to the negative terminal
of the discharged battery. The resulting electrical
spark could cause the battery to explode.
²During cold weather when temperatures are be-
low freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump starting
because the battery could rupture or explode. The
battery temperature must be brought up above
freezing point before attempting to jump start.
3. Take care that the clamps from one cable do not touch
clamps from the other cable. Do not lean over the battery
when making the connection. The negative connection
must provide good electrical conductivity and current
carrying capacity.4. After the engine is started or if the engine fails to start,
the cables must be disconnected in the following order:
a. Disconnect the negative cable at the engine
ground.
b. Disconnect the negative cable at the negative
terminal on the booster battery.
c. Disconnect the cable from the positive terminals
of both batteries.
WARNING!
Any procedure other than above could result in:
²Personal injury caused by electrolyte squirting
out the battery vent.
²Personal injury or property damage due to battery
explosion.
²Damage to charging system of booster vehicle or
of immobilized vehicle.
