Air Bag Warning Light
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 ignition switch is in the OFF position or in the
ACC position, 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 bag system even if the battery loses power or
it becomes disconnected prior to deployment.
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 switch is first in the
ON/RUN position. After the self-check, the Air Bag Warn-
ing 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 to alert you if the light comes on again after
initial startup. The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is
detected that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction. While the air
bag system is designed to be maintenance free, if any of the
following occurs, have an authorized dealer service the air
bag system immediately.
•
The Air Bag Warning Light does not come on during the
four to eight seconds when the ignition switch is first in
the ON/RUN position.
• The Air Bag Warning Light remains on after the four to
eight-second interval.
• The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. In this condition
the air bags may not be ready to inflate for your protection.
Have an authorized dealer service the air bag system
immediately.

WARNING!
Ignoring the Air Bag Warning Light in your instrument
panel could mean you won’t have the air bag system 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.
Front Air Bags
This vehicle has front air bags for both the driver and front
passenger as a supplement to the seat belt restraint sys-
tems. The driver front air bag is mounted in the center of
the steering wheel. The passenger front air bag is mounted
in the instrument panel, above the glove compartment. The
words “SRS AIRBAG” or “AIRBAG” are embossed on the
air bag covers.
WARNING!
•Being too close to the steering wheel or instrument
panel during 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.

WARNING!(Continued)
•Never place a rear-facing child restraint in front of an
air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.
• Only use a rear-facing child restraint in a vehicle
with a rear seat.
Driver and Passenger 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 deter-
mined by the Occupant Restraint Controller (ORC), which
may receive information from the front impact sensors (if
equipped) or other system components.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. A low energy
output is used in less severe collisions. A higher energy
output is used for more severe collisions.
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 buckled. The seat belt
buckle switch may adjust the inflation rate of the Ad-
vanced Front Air Bags.
WARNING!
•
No objects should be placed over or near the air bag
on the instrument panel or steering wheel because
any such objects could cause harm if the vehicle is in
a collision severe enough to cause the air bag to
inflate.
• Do not put anything on or around the air bag covers
or attempt to open them manually. You may damage
the air bags and you could be injured because the air
bags may no longer be functional. The protective
covers for the air bag cushions are designed to open
only when the air bags are inflating.
• 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, air bags won’t deploy at all. Always wear
your seat belts even though you have air bags.

Front Air Bag Operation
Front Air Bags are designed to provide additional protec-
tion by supplementing the seat belts. Front air bags are not
expected to reduce the risk of injury in rear, side, or
rollover collisions. The 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, front air bags may deploy in crashes with little
vehicle front-end damage but that produce a severe initial
deceleration.
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 collisions,
and also are needed to help keep you in position, away
from an inflating air bag.
When the ORC detects a collision requiring the front air
bags, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air bags.The steering wheel hub trim cover and the upper right side
of the instrument panel separate and fold out of the way as
the air bags inflate to their full size. The front air bags fully
inflate in less time than it takes to blink your eyes. The
front air bags then quickly deflate while helping to restrain
the driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and front passenger, and position the front occu-
pants for improved interaction with the front air bags.
WARNING!
•
Do not drill, cut, or tamper with the knee impact
bolsters in any way.
• Do not mount any accessories to the knee impact
bolsters such as alarm lights, stereos, citizen band
radios, etc.
Supplemental Side Air Bags
Your vehicle is equipped with two types of side air bags:
1. Supplemental Seat-Mounted Side Air Bags (SABs):
Located in the outboard side of the front seats. The
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

SABs are marked with a “SRS AIRBAG” or “AIR-
BAG” label sewn into the outboard side of the seats.
The SABs may help to reduce the risk of occupant injury
during certain side impacts and/or vehicle rollover events,
in addition to the injury reduction potential provided by
the seat belts and body structure. When the SAB deploys, it opens the seam on the outboard
side of the seatback’s trim cover. The inflating SAB deploys
through the seat seam into the space between the occupant
and the door. The SAB moves at a very high speed and
with such a high force that it could injure occupants if they
are not seated properly, or if items are positioned in the
area where the SAB inflates. Children are at an even greater
risk of injury from a deploying air bag.
WARNING!
Do not use accessory seat covers or place objects
between you and the Side Air Bags; the performance
could be adversely affected and/or objects could be
pushed into you, causing serious injury.

2.Supplemental Side Air Bag Inflatable Curtains
(SABICs): Located above the side windows. The trim
covering the SABICs is labeled “SRS AIRBAG” or
“AIRBAG.”
SABICs may help reduce the risk of head or other injuries
to front and rear seat outboard occupants in certain side
impacts and/or vehicle rollover events, in addition to the
injury reduction potential provided by the seat belts and
body structure.
The SABICs deploy downward, covering the side win-
dows. An inflating SABIC pushes the outside edge of the trim out of the way and covers the window. The SABICs
inflate with enough force to injure occupants if they are not
belted and seated properly, or if items are positioned in the
area where the SABICs inflate. Children are at an even
greater risk of injury from a deploying air bag.
WARNING!
•
Do not stack luggage or other cargo up high enough
to block the deployment of the SABICs. The trim
covering above the side windows where the SABIC
and its deployment path are located should remain
free from any obstructions.
• In order for the SABICs to work as intended, do not
install any accessory items in your vehicle which
could alter the roof. Do not add an aftermarket
sunroof to your vehicle. Do not add roof racks that
require permanent attachments (bolts or screws) for
installation on the vehicle roof. Do not drill into the
roof of the vehicle for any reason.
The SABICs and SABs (Side Air Bags) are designed to
activate in certain side impacts and certain rollover events.
The Occupant Restraint Controller (ORC) determines
whether the deployment of the Side Air Bags in a particular
side impact or rollover event is appropriate, based on the

severity and type of collision. Vehicle damage by itself is
not a good indicator of whether or not Side Air Bags should
have deployed.
Side Air Bags are a supplement to the seat belt restraint
system. Side Air Bags deploy in less time than it takes to
blink your eyes.
WARNING!
•Occupants, including children, who are up against or
very close to Side Air Bags can be seriously injured
or killed. Occupants, including children, should
never lean on or sleep against the door, side win-
dows, or area where the side air bags inflate, even if
they are in an infant or child restraint.
• Seat belts (and child restraints where appropriate)
are necessary for your protection in all collisions.
They also help keep you in position, away from an
inflating Side Air Bag. To get the best protection
from the Side Air Bags, occupants must wear their
seat belts properly and sit upright with their backs
against the seats. Children must be properly re-
strained in a child restraint or booster seat that is
appropriate for the size of the child.
WARNING!
• Side Air Bags need room to inflate. Do not lean
against the door or window. Sit upright in the center
of the seat.
• Being too close to the Side Air Bags during deploy-
ment could cause you to be severely injured or
killed.
• Relying on the Side Air Bags alone could lead to
more severe injuries in a collision. The Side Air Bags
work with your seat belt to restrain you properly. In
some collisions, Side Air Bags won’t deploy at all.
Always wear your seat belt even though you have
Side Air Bags.
NOTE: Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.
Side Impacts
In side impacts, the side impact sensors aid the ORC in
determining the appropriate response to impact events.
The system is calibrated to deploy the Side Air Bags on the
impact side of the vehicle during impacts that require Side
Air Bag occupant protection. In side impacts, the Side Air2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 61

Bags deploy independently; a left side impact deploys the
left Side Air Bags only and a right side impact deploys the
right Side Air Bags only.
The Side Air Bags will not deploy in all side collisions,
including some collisions at certain angles, or some side
collisions that do not impact the area of the passenger
compartment. The Side Air Bags may deploy during
angled or offset frontal collisions where the front air bags
deploy.
Rollover Events
Side Air Bags are designed to activate in certain rollover
events. The ORC determines whether the deployment of
the Side Air Bags in a particular rollover event is appro-
priate, based on the severity and type of collision. Vehicle
damage by itself is not a good indicator of whether or not
Side Air Bags should have deployed.
The Side Air Bags will not deploy in all rollover events. The
rollover sensing-system determines if a rollover event may
be in progress and whether deployment is appropriate. A
slower-developing event may deploy the seat belt preten-
sioners on both sides of the vehicle. A faster-developing
event may deploy the seat belt pretensioners as well as the
Side Air Bags on both sides of the vehicle. The rolloversensing-system may also deploy the seat belt pretension-
ers, with or without the Side Air Bags, on both sides of the
vehicle if the vehicle experiences a near rollover event.
The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain rollover or side impact events.
The Occupant Restraint Controller (ORC) monitors the
internal circuits and interconnecting wiring associated
with electrical Air Bag System Components listed below:
Supplemental Side Air Bags — If Equipped
Your vehicle is equipped with two types of side air bags:
1.
Supplemental Seat-Mounted Side Air Bags (SABs) (If
Equipped): Located in the outboard side of the front
seats. The SABs are marked with a “SRS AIRBAG” or
“AIRBAG” label sewn into the outboard side of the
