indicator, it means that the passenger
sensing system has turned off the
front outboard passenger frontal
airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See your

Maintenance test or to service the
vehicle may affect vehicle operation.
SeeAdd-On Electrical Equipment 0246.
See your dealer if assistance is needed.
The vehicle may not pass
inspection if:
. The light is on when the engine is
running. .
The light does not come on when
the ignition is in Service Mode.
. Critical emission control systems
have not been completely

12-volt battery has recently been
replaced or run down, or if the
vehicle has been recently serviced.
See your dealer if the vehicle will not
pass or cannot be made ready for
the test.
