Jeep Wrangler: Jump Starting Procedure / Disconnecting The Jumper Cables
- Disconnect the negative (-) end of the
jumper cable from the engine ground of
the vehicle with the discharged battery.
- Disconnect the opposite end of the negative
(-) jumper cable from the negative (-) post of
the booster battery.
- Disconnect the positive (+) end of the
jumper cable from the positive (+) post of
the booster battery.
- Disconnect the opposite end of the positive
(+) jumper cable from the remote positive
(+) post of the discharged vehicle.

NOTE:
If frequent jump starting is required to start your
vehicle you should have the battery and
charging system tested at an authorized dealer.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular devices,
etc.). Eventually, if plugged in long enough
without engine operation, the vehicle’s
battery will discharge sufficiently to degrade
battery life and/or prevent the engine from
starting.
Connect the positive (+) end of the jumper
cable to the remote positive (+) post of the
discharged vehicle.
Connect the opposite end of the positive (+)
jumper cable to the positive (+) post of the
booster battery...
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action...
