FRONT PASSENGER AIR BAG STATUS LIGHT OPERATION
NOTE: Please print this page and place a copy in the vehicle.
Quality Action PC835 changes the operation of the passenger air bag status light.

The passenger air bag status light will now be ON (illuminated) when the front passenger seat is
empty.
Below is additional information regarding the operation of the passenger air bag status light.
The front passenger seat is equipped with an occupant classification
sensor (weight sensor) that turns the front passenger air bag on or off
depending on the weight applied to the front passenger seat. The status
of the front passenger air bag (ON or OFF) is indicated by the front
passenger air bag status light
which is located on the instrument
panel. After the ignition switch is placed in the “ON” position, the front
passenger air bag status light on the instrument panel illuminates for
about 7 seconds and then turns off or remains illuminated depending on
the front passenger seat occupied status. The light operates as follows:
