THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 11

The Advanced Front Air Bags have a multistage inflator
design. This allows the air bag to have different rates of
inflation that are based on several factors, including the
severity and type of collision.
This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Air Bags based upon
seat position.
This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether
the driver or front passenger seat belt is fastened. The
seat belt buckle switch may adjust the inflation rate of the
Advanced Front Air Bags.
This vehicle is equipped with Supplemental Side Air Bag
Inflatable Curtains (SABIC) to protect the driver, front,
and rear passengers sitting next to a window. The SABIC
are located above the side windows. The trim covering
the side air bags is labeled SRS AIRBAG.This vehicle may be equipped with Supplemental Seat-
Mounted Side Air Bags (SAB) to provide enhanced
protection for an occupant during a side impact. The
Supplemental Seat-Mounted Side Air Bags are located in
the outboard side of the front seats.
NOTE:
•Air Bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
•After any accident, the vehicle should be taken to an
authorized dealer immediately.
Air Bag System Components
Your vehicle may be equipped with the following air bag
system components:
•Occupant Restraint Controller (ORC)
•Air Bag Warning Light
•Steering Wheel and Column

Advanced Front Air Bag Features
The Advanced Front Air Bag system has multistage
driver and front passenger air bags. This system provides
output appropriate to the severity and type of collision as
determined by the Occupant Restraint Controller (ORC),
which may receive information from the front impact
sensors.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. This low output
is used in less severe collisions. A higher energy output is
used for more severe collisions.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 63

•Being too close to the Supplemental Side Air Bag
Inflatable Curtain and/or Seat-Mounted Side Air Bag
during deployment could cause you to be severely
injured or killed.
The system includes side impact sensors that are cali-
brated to deploy the side air bags during impacts that
require air bag occupant protection.
WARNING!
•Your vehicle is equipped with left and right
Supplemental Side Air Bag Inflatable Curtain
(SABIC), do not stack luggage or other cargo up
high enough to block the location of the SABIC.
The area where the SABIC is located should re-
main free from any obstructions. (Continued)
WARNING! (Continued)
•Do not use accessory seat covers or place objects
between you and the side air bags; the perfor-
mance could be adversely affected and/or objects
could be pushed into you, causing serious injury.
•If your vehicle is equipped with SABIC air bags,
do not have any accessory items installed which
will alter the roof, including adding a sunroof to
your vehicle. Do not add roof racks that require
permanent attachments (bolts or screws) for instal-
lation on the vehicle roof. Do not drill into the roof
of the vehicle for any reason.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and the front passenger, and position front occu-
pants for the best interaction with the Advanced Front
Air Bags.
66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Along with seat belts and pretensioners, Advanced Front
Air Bags work with the knee bolsters to provide im-
proved 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)
TheORC 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, Supplemental Seat-Mounted Side Air Bags — if
equipped, and front seat belt pretensioners, as required,
depending on several factors, including the severity and
type of impact. Advanced Front Air Bags are designed to provide addi-
tional protection by supplementing the seat belts in
certain frontal 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 will not deploy in all
frontal collisions, including some that may produce sub-
stantial vehicle damage — for example, some pole colli-
sions, 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.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 67

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.
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 approxi-
mately four to eight seconds for a self-check
when the ignition is first turned on. 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 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.
68 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Based on several factors, including the severity and type
of collision, the side air bag inflator on the crash side of
the vehicle may be triggered, releasing a quantity of
non-toxic gas. The inflating SAB exits through the seat
seam into the space between the occupant and the door.
The SAB fully inflate in about 10 milliseconds. The side
air bag moves at a very high speed and with such a high
force that it could injure you if you are not seated
properly, or if items are positioned in the area where the
side air bag inflates. This especially applies to children.
Supplemental Side Air Bag Inflatable Curtain
(SABIC) Inflator Units
During collisions where the impact is confined to a
particular area of the side of the vehicle, the ORC may
deploy the SABIC air bags, depending on several factors,
including the severity and type of collision. In these
events, the ORC will deploy the SABIC only on the
impact side of the vehicle.A quantity of non-toxic gas is generated to inflate the side
curtain air bag. The inflating side curtain air bag pushes
the outside edge of the headliner out of the way and
covers the window. The air bag inflates in about 30 milli-
seconds (about one-quarter of the time that it takes to
blink your eyes) with enough force to injure you if you
are not belted and seated properly, or if items are
positioned in the area where the side curtain air bag
inflates. This especially applies to children. The side
curtain air bag is only about 3-1/2 in (9 cm) thick when
it is inflated.
Because air bag sensors estimate deceleration over time,
vehicle speed and damage are not good indicators of
whether or not an air bag should have deployed.
NOTE:
In a rollover the pretensioners and/or SAB and
SABIC air bags may deploy on both sides of the vehicle.
70 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Front And Side Impact Sensors
In front and side impacts, impact sensors can aid the
ORC in determining appropriate response to impact
events.
Enhanced Accident Response System
In the event of an impact causing air bag deployment, if
the communication network remains intact, and the
power remains intact, depending on the nature of the
event the ORC will determine whether to have the
Enhanced Accident Response System perform the follow-
ing functions:
•Cut off fuel to the engine.
•Flash hazard lights as long as the battery has power or
until the ignition key is turned off.
•Turn on the interior lights, which remain on as long as
the battery has power or until the ignition key is
removed.
•Unlock the doors automatically.
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from IGN ON to IGN OFF.
If A Deployment Occurs
The Advanced Front Air Bags are designed to deflate
immediately after deployment.
NOTE: Front and/or side air bags will not deploy in all
collisions. This does not mean something is wrong with
the air bag system.
If you do have a collision, which deploys the air bags, any
or all of the following may occur:
•The nylon air bag material may sometimes cause
abrasions and/or skin reddening to the driver and
front passenger as the air bags deploy and unfold. The
abrasions are similar to friction rope burns or those
you might get sliding along a carpet or gymnasium
