Monitoring the
Advanced Airbag
System
Airbag monitoring indicator light
Two separate indicators monitor the function
of the Advanced Airbag System : the airbag
moni toring indicator light and the
PASSEN-
GER AIR BAG OFF
light.
The Advanced Airbag System (includ ing the
electronic control unit, sensor circuits and sys-
tem wiring) is monitored continuous ly to
make sure that it is functioning properly
whenever the ignit ion is on. Each t ime you
turn on the ignition, the airbag monitor ing in-
dicator light
I will come on for a few seconds
(self diagnostics) .
The system mu si be inspected when the
indicator light :
- does not come on when the ignit ion is
switched on,
- does not go out a few seconds afte r you
have swit ched on the ignition, or
- comes on wh ile driving .
If an airbag system malfunction is detected,
t he 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-
GER AIR BAG OFF
light w ill come on and stay
on whenever the ignition is on.

properly cannot provide supp lemental pro-
tection in a fron t al crash.
- If the airbag indicator light comes on, it
means that there may be somet hing
wrong with the Advanced Airbag System.

flate when it should.
