2004 JEEP WRANGLER heater

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.
