Advanced Front Air Bags and Supplemental
Driver Side Knee Air Bag are designed to
provide additional protection by supplementing
the seat belts in certain frontal collisions de-
pending on several factors, including the sever-
ity and type of collision. Advanced Front Air
Bags are not expected to reduce the risk of
injury in rear, or side collisions.
The Advanced Front Air Bags and Supplemen-
tal Driver Side Knee Air Bag will not deploy in all
frontal collisions, including some that may pro-
duce substantial vehicle damage — for ex-
ample, some pole collisions, truck underrides,
and angle offset collisions. On the other hand,
depending on the type and location of impact,
Advanced Front Air Bags may deploy in crashes
with little vehicle front-end damage but that
produce a severe initial deceleration.
The side air bags will not deploy in all side
collisions. Side air bag deployment will depend
on the severity and type of collision.
Because air bag sensors measure vehicle decel-
eration over time, vehicle speed and damage by
themselves are not good indicators of whether or
not an air bag should have deployed.
Seat belts are necessary for your protection in
all collisions, and also are needed to help keep
you in position, away from an inflating air bag.
The ORC monitors the readiness of the elec-
tronic parts of the air bag system whenever the
ignition switch is in the START or ON/RUN
position. If the key is in the LOCK position, in the
ACC position, or not in the ignition, the air bag
system is not on and the air bags will not inflate.
The ORC contains a backup power supply
system that may deploy the air bags even if the
battery loses power or it becomes disconnected
prior to deployment.
Also, the ORC turns on the Air Bag
Warning Light in the instrument
panel for approximately four to
eight seconds for a self-check
when the ignition is first turned to
the ON/RUN position. After the self-check, the
Air Bag Warning Light will turn off. If the ORC
detects a malfunction in any part of the system,
it turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime will
sound if the light comes on again after initial
startup.
It also includes diagnostics that will illuminate
the instrument cluster Air Bag Warning Light if a
malfunction is noted that could affect the air bag
system. The diagnostics also record the nature
of the malfunction.
WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won't have
the air bags to protect you in a collision. If the
light does not come on as a bulb check when
the ignition is first turned on, stays on after
you start the vehicle, or if it comes on as you
drive, have an authorized dealer service the
air bag system immediately.
