improved protection for the driver and front passenger.
Side air bags also work with seat belts to improve
occupant protection.
Air Bag Deployment Sensors And Controls
Occupant Restraint Controller (ORC)
The ORC is part of a Federally 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 signals, a central electronic
ORC deploys the Advanced Front Air Bags, SABIC air
bags, SABs, Supplemental Driver Side Knee Air Bag, and
front seat belt pretensioners, as required, depending on
several factors, including the severity and type of impact.
Advanced Front Air Bags and Supplemental Driver Side
Knee Air Bag are designed to provide additional protec-
tion by supplementing the seat belts in certain frontal
Because air bag sensors measure vehicle deceleration
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 colli-
sions, and also are needed to help keep you in position,
away from an inflating air bag.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch is in the
START or ON/RUN position. If the key is in the OFF
position, in the ACC position, or not in the ignition, the
air bag system is not on and the air bags will not inflate.
collisions depending on several factors, including 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 and Supplemental Driver
Side Knee Air Bag will not deploy in all frontal collisions,
including some that may produce substantial vehicle
damage — for example, 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.

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.
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 instru-
ment cluster Air Bag Warning Light if a malfunction is
noted that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction.
