Once the engine is started, remove the jumper cables in
the reverse sequence:
6. Disconnect the negative (-) jumper cable from the
engine ground of the vehicle with the discharged
battery.
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 positive (+) 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 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 without engine operation, 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. Then shift back and forth between DRIVE and
REVERSE (with automatic transmission) or 2nd gear and
REVERSE (with manual transmission), while gently press-
ing the accelerator. Use the least amount of accelerator pedal
pressure that will maintain the rocking motion, without
spinning the wheels, or racing the engine.
