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 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 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 buckled. The seat
belt buckle switch may adjust the inflation rate of the
Advanced 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 bags 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. Al-
ways wear your seat belts even though you have air
bags.
Advanced Front Air Bag Operation
Advanced Front Air Bags are designed to provide addi-
tional protection by supplementing the seat belts. Ad-
vanced Front Air Bags are not expected to reduce the risk
of injury in rear, side, or rollover collisions. The Ad-
vanced Front Air Bags 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.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.
When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate the
Advanced 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 Advanced
Front Air Bags fully inflate in less time than it takes to
blink your eyes. The 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 Advanced 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 Driver Knee Air Bag
This vehicle is equipped with a Supplemental Driver
Knee Air Bag mounted in the instrument panel below the
steering column. The Supplemental Driver Knee Air Bag
provides enhanced protection during a frontal impact by
working together with the seat belts, pretensioners, and
Advanced Front Air Bags.
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
SABs are marked with “SRS AIRBAG” or “AIRBAG”
air bag label sewn into the outboard side of the seats.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 71

The SABs may help to reduce the risk of occupant injury
during certain side impact and certain 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 out-
board 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 you if you 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.Front Supplemental Seat-Mounted Side Air Bag Label
72 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 injury to front
and rear seat outboard occupants. SABICs may reduce
the risk of injuries in certain side impact and vehicle
rollover events, in addition to the injury reduction poten-
tial 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 you if you 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.
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.

WARNING!
•Your vehicle is equipped with left and right
Supplemental Side Air Bag Inflatable Curtains
(SABICs). Do not stack luggage or other cargo up
high enough to block the deployment of the
SABICs. The trim covering above the side win-
dows where the SABIC and its deployment path
are located should remain free from any obstruc-
tions.
•Your vehicle is equipped with SABICs. 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 perma-
nent 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”) de-
termines 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. 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 windows, 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
74 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

help keep you in position, away from inflating Side Air
Bags. 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 restrained 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 Air 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.2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 75

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 Advanced
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 pretensioners on both sides of the vehicle. Afaster-developing event may deploy the seat belt preten-
sioners as well as the SABs and SABICs on both sides of
the vehicle. The rollover sensing-system may also deploy
the seat belt pretensioners, with or without the SABs and
SABICs, on both sides of the vehicle if the vehicle
experiences a near rollover event.
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 air bag material may sometimes cause abrasions
and/or skin reddening to the occupants as the air bags
76 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

deploy and unfold. The abrasions are similar to fric-
tion rope burns or those you might get sliding along a
carpet or gymnasium floor. They are not caused by
contact with chemicals. They are not permanent and
normally heal quickly. However, if you haven’t healed
significantly within a few days, or if you have any
blistering, see your doctor immediately.
•As the air bags deflate, you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the non-toxic gas used for air
bag inflation. These airborne particles may irritate the
skin, eyes, nose, or throat. If you have skin or eye
irritation, rinse the area with cool water. For nose or
throat irritation, move to fresh air. If the irritation
continues, see your doctor. If these particles settle on
your clothing, follow the garment manufacturer ’s in-
structions for cleaning.Do not drive your vehicle after the air bags have de-
ployed. If you are involved in another collision, the air
bags will not be in place to protect you.
WARNING!
Deployed air bags and seat belt pretensioners cannot
protect you in another collision. Have the air bags,
seat belt pretensioners, and the seat belt retractor
assemblies replaced by an authorized dealer imme-
diately. Also, have the Occupant Restraint Controller
System serviced as well.
NOTE:
•Air bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
•After any collision, the vehicle should be taken to an
authorized dealer immediately.

Enhanced Accident Response System
In the event of an impact, 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 Sys-
tem perform the following functions:
•Cut off fuel to the engine.
•Flash hazard lights as long as the battery has power or
until the ignition is placed in the “OFF” position.
•Turn on the interior lights, which remain on as long as
the battery has power or until the ignition is placed in
the “OFF” position.
•Unlock the doors automatically.
System Reset Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from ignition START or ON/RUN to ignition
OFF.
Air Bag Warning Light
The air bags must be ready to inflate for your
protection in a collision. The Occupant Re-
straint Controller (ORC) monitors the internal
circuits and interconnecting wiring associated
with air bag system electrical components.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition is in the START
or ON/RUN position. If the ignition is in the OFF
position or in the ACC position, the air bag system is not
on and the air bags will not inflate.
