Jeep 2014 Wrangler - User Guide - Manual (Page 114)

Once the engine is started, remove the jumper cables in the reverse sequence:
1. Disconnect the negative (-) end of the jumper cable from the engine ground of the
vehicle with the discharged battery.
2. Disconnect the opposite end of the negative (-) jumper cable from the negative (-)
post of the booster battery.
3. Disconnect the positive (+) end of the jumper cable from the positive (+) post of
the booster battery.
4. Disconnect the opposite end of the positive (+) jumper cable from the positive (+)
post of the vehicle with the discharged battery.
NOTE:
If frequent jump-starting is required to start your vehicle you should have the battery
and charging system inspected at your authorized dealer.
CAUTION!
• Do not use a portable battery booster pack or any other booster source with a
system voltage greater than 12 Volts or damage to the battery, starter motor,
alternator or electrical system may occur.
• Failure to follow these procedures could result in damage to the charging
system of the booster vehicle or the discharged vehicle.
• Accessories that can be plugged into the vehicle power outlets draw power from
the vehicle’s battery, even when not in use (e.g., cellular phones, etc.).
Eventually, if plugged in long enough, the vehicle’s battery discharges suffi-
ciently to degrade battery life and/or prevent the engine from starting.
