Inflated right front passenger side air bag
If the air bag is inflated, THE AIR BAG
WILL NOT FUNCTION AGAIN AND
MUST BE REPLACED IMMEDIATELY. If
the air bag is not replaced, the unrepaired
area will increase the risk of injury in a
collision.
The air bag system uses a readiness light and a
tone to indicate the condition of the system. The
readiness light is in the instrument cluster. When
you turn the ignition to the ON position, this
light will illuminate for approximately six (6)
seconds and then turn off. This indicates that the
system is operating normally. NOTE:
Maintenance of the air bag system is not
required.
