This light indicates that the Air Bag system is not functional
and needs to be serviced. The light illuminates for
approximately six seconds when the ignition is turned to the

light fails to illuminate, flashes continuously, or remains on,
have the air bag system serviced as soon as possible.

Charging System Light
This light indicates that your battery is not being charged. The
light comes on briefly during the display self-test every time
you turn your ignition key to the ON position. The light will go
off when the key is turned to the START position. The light
should stay off when the self-test is done if the engine is
running and the alternator is charging.
If the light stays on or comes on when the engine is running,
have the electrical system checked as soon as possible.
