WHAT TO DO IN EMERGENCIES 571
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 the vehicle becomes stuck in snow, sand or mud, it can
often be moved by a rocking motion. Move the shift lever
rhythmically between DRIVE and REVERSE while ap-
plying slight pressure to the accelerator. In general, the
least amount of accelerator pedal pressure to maintain
the rocking motion without spinning the wheels or racing
the engine is most effective.
