Jeep 2013 Grand Cherokee - Manual (Page 599)

Once the engine is started, remove the jumper cables in
the reverse sequence:
6. Disconnect the negative (-) jumper cable from the
remote negative (-) post of the discharged vehicle.
7. Disconnect the negative end (-) of the jumper cable
from the negative (-) post of the booster battery.
8. Disconnect the opposite end of the positive (+) jumper
cable from the positive (+) post of the booster battery.
9. Disconnect the positive (+) end of the jumper cable
from the remote positive (+) post of the discharged
vehicle.
10. Reinstall the protective cover over the remote posi-
tive (+) battery post of the discharged vehicle.
If frequent jump-starting is required to start your vehicle
you should have the battery and charging system in-
spected at your authorized dealer.
CAUTION!
Accessories that can be plugged into the vehicle
power outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the vehicle’s
battery will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved using a rocking motion. Turn the
steering wheel right and left to clear the area around the
front wheels. Press and hold the lock button on the shift
lever. Then shift back and forth between DRIVE and
REVERSE while gently pressing the accelerator.
