5. If the air bag system in this vehicle needs to
be modified to accommodate a disabled per-
son, contact the customer center. Phone num-
bers are provided under “If You Need Assis-
tance”.
WARNING!
•
Relying on the air bags alone could lead to
more severe injuries in a collision. The air
bags work with your seat belt to restrain
you properly. In some collisions, the air
bags won’t deploy at all. Always wear your
seat belts even though you have air bags.
•
Being too close to the steering wheel or
instrument panel during Advanced Front Air
Bag deployment could cause serious injury,
including death. Air Bags need room to
inflate. Sit back, comfortably extending
your arms to reach the steering wheel or
instrument panel.
•
Side air bags need room to inflate. Do not
lean against the door or window. Sit upright
in the center of the seat.
Air Bag Deployment Sensors And Controls
Occupant Restraint Controller (ORC)
The ORC is part of a regulated safety system
required for this vehicle.
The ORC determines if deployment of the front
and/or side air bags in a frontal or side collision
is required. Based on the impact sensor’s sig-
nals, a central electronic ORC deploys the
Advanced Front Air Bags, SABIC air bags, and
front seat belt pretensioners, as required, de-
pending on the severity and type of impact.
Advanced Front Air Bags are designed to pro-
vide additional protection by supplementing
the seat belts in certain frontal collisions de-
pending on the severity and type of collision.
Advanced Front Air Bags are not expected to
reduce the risk of injury in rear, side, or rollover
collisions.
The Advanced Front Air Bags will not deploy in
all frontal collisions, including some that may
produce substantial vehicle damage — for
example, some pole collisions, truck under-
rides, 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 de-
celeration over time, vehicle speed and dam-
age by themselves are not good indicators of
whether or not an air bag should have de-
ployed.
Seat belts are necessary for your protection in
all crashes, and also are needed to help keep
you in position, away from an inflating air bag.
The ORC also monitors the readiness of the
electronic parts of the air bag system whenever
the ignition switch is in the START or ON/RUN
positions. 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 discon-
nected prior to deployment.
