PASSENGER AIR BAG ON/OFF
INDICATOR
When you start the vehicle, the
system will perform a self-check.
The air bag "on" and "off" indica-
tors will appear briefly in the
passenger air bag on/off indicator
(located on the instrument panel).
When the system self-check is
complete, one of the indicators
will stay on to indicate whether the
front passenger's frontal air bag is
on or off.
If the two indicators never appear
when the vehicle is first started, or
if after several seconds both indica-
tors remain lit, there may be a
problem with the system. See your
dealer for service.
CAUTION
If the passenger air bag "off"
indicator is on and the Air Bag
Light turns on, there is a prob-
lem with the air bag system.
The adult-sized passenger may
not have the protection of the
air bag system. Have the vehicle
serviced right away.
See "Air Bag Light" in Section 1
for more information.
Section 2
CAUTION
When the vehicle is started with
a child restraint installed in the
front passenger seat, the "off"
indicator should appear in the
passenger air bag on/off indica-
tor (located on the instrument
panel) after the system has
completed its self-check.
If the "on" indicator appears
when you have installed a child
restraint in the front passenger
seat, it means that the front
passenger's air bag system is
still active.
