electronic control unit, sensor circuits and sys-
tem wiring) is monitored continuously to
make sure that it is functioning properly
whenever the ignit ion is on. Each time you
turn on the ignition, the airbag monitoring in-
dicator light

The system must be inspected when the
indicator light
I :
- does not come on when the ignit ion is
switched on,
- does not go out a few seconds after you
have switched on the ignition, or
- comes on while driving.
If an airbag system malfunction is detected,
the indicator light will first start flashing to
catch the driver's attention and then stay on
continuously to serve as a constant reminder
to have the system inspected immediately.
If a malfunction occurs that turns the front
airbag on the passenger side off, the
PASSEN-

OFF light will come on and stay
on whenever the ignition is on.

properly cannot provide supplemental pro-
