Advanced Front Airbag FeaturesThe Advanced Front Airbag system has multi-
stage driver and front passenger airbags. This
system provides output appropriate to the se-
verity 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 airbag deploy- ment. This low output is used in less severe
collisions. A higher energy output is used for
more severe collisions.
WARNING!
•
No objects should be placed over or near
the airbag on the instrument panel, be-
cause any such objects could cause harm if
the vehicle is in a collision severe enough
to cause the airbag to inflate.
• Do not put anything on or around the airbag
covers or attempt to open them manually.
You may damage the airbags and you
could be injured because the airbags may
no longer be functional. The protective cov-
ers for the airbag cushions are designed to
open only when the airbags are inflating.
• Do not drill, cut or tamper with the knee
bolster in any way.
• Do not mount any accessories to the knee
bolster such as alarm lights, stereos, citi-
zen band radios, etc. Supplemental Seat-Mounted Side Airbags
(SAB)
Supplemental Seat-Mounted Side Airbags pro-
vide enhanced protection to help protect an
occupant during a side impact. The Supple-
mental Seat-Mounted Side Airbag is marked
with an airbag label sewn into the outboard
side of the front seats.
When the airbag deploys, it opens the seam
between the front and side of the seat’s trim
cover. Each airbag deploys independently, that
is a left side impact deploys the left airbag only
and a right-side impact deploys only the right
airbag.

WARNING!(Continued)
• Being too close to the Supplemental Side
Airbag Inflatable Curtain (SABIC) and/or
Seat-Mounted Side Airbag (SAB) during
deployment could cause you to be severely
injured or killed.
Airbag 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 airbags in a frontal or side collision
is required. Based on the impact sensors sig-
nals, a central electronic ORC deploys the
Advanced Front Airbags, Supplemental Driver
Side Knee Airbag, Supplemental Side Airbag
Inflatable Curtain (SABIC), Supplemental Seat-
Mounted Side Airbags (SAB), and front seat
belt pretensioners, as required, depending on
the severity and type of impact. Advanced Front Airbags and knee airbag are
designed to provide additional protection by
supplementing the seat belts in certain frontal
collisions depending on the severity and type
of collision. Advanced Front Airbags are not
expected to reduce the risk of injury in rear, or
side collisions.
The Advanced Front Airbags and knee airbag
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 Airbags
may deploy in crashes with little vehicle front-
end damage but that produce a severe initial
deceleration.
The side airbags will not deploy in all side
collisions. Side airbag deployment will depend
on the severity and type of collision.
Because airbag sensors measure vehicle de-
celeration over time, vehicle speed and dam-
age by themselves are not good indicators of
whether or not an airbag should have de-
ployed.Seat belts are necessary for your protection in
all accidents, and also are needed to help keep
you in position, away from an inflating airbag.
The ORC monitors the readiness of the elec-
tronic parts of the airbag system whenever the
ignition switch is in the START or ON/RUN
position. If the key is in the LOCK position, in
the ACC position, or not in the ignition, the
airbag system is not on and the airbags will not
inflate.
The ORC contains a backup power supply
system that may deploy the airbags even if the
battery loses power or it becomes discon-
nected prior to deployment.
Also, the ORC turns on the Airbag
Warning Light in the instrument
panel for approximately four to
eight seconds for a self-check
when the ignition is first turned to
the ON/RUN position. After the
self-check, the Airbag Warning Light will turn
off. If the ORC detects a malfunction in any part
of the system, it turns on the Airbag Warning
Light, either momentarily or continuously. A
41

single chime will sound if the light comes on
again after initial startup.
It also includes diagnostics that will illuminate
the instrument cluster Airbag Warning Light if a
malfunction is noted that could affect the airbag
system. The diagnostics also record the nature
of the malfunction.
WARNING!
Ignoring the Airbag Warning Light in your
instrument panel could mean you won’t have
the airbags to protect you in a collision. If the
light does not come on, stays on after you
start the vehicle, or if it comes on as you drive,
have an authorized dealer service the airbag
system immediately.
Driver and Passenger Advanced Front
Airbag Inflator Units
The Driver and Passenger Advanced Front
Airbag Inflator Units are located in the center of
the steering wheel and the right side of the
instrument panel. When the ORC detects a
collision requiring the Advanced Front Airbags,
it signals the inflator units. A large quantity of non-toxic gas is generated to inflate the Ad-
vanced Front Airbags. Different airbag inflation
rates are possible, based on the collision type
and severity. The steering wheel hub trim cover
and the upper right side of the instrument panel
separate and fold out of the way as the airbags
inflate to their full size. The airbags fully inflate
in about 50 to 70 milliseconds. This is about half
of the time it takes to blink your eyes. The
airbags then quickly deflate while helping to
restrain the driver and front passenger.
The Advanced Front Airbag gas is vented
through the vent holes in the sides of the
airbag. In this way, the airbags do not interfere
with your control of the vehicle.
Supplemental Driver Side Knee Airbag
Inflator Unit
The driver side knee airbag unit is located in
the instrument panel trim beneath the steering
column. When the ORC detects a collision
requiring the airbag, it signals the inflator units.
A large quantity of non-toxic gas is generated
to inflate the knee airbag. The trim cover sepa-
rates and folds out of the way allowing the
airbag to inflate to the full size. The airbag fully
inflates in about 15 to 20 milliseconds.Supplemental Seat-Mounted Side Airbag
(SAB) Inflator Units
The Supplemental Seat-Mounted Side Airbags
are designed to activate only in certain side
collisions.
The ORC determines if a side collision requires
the side airbags to inflate based on the severity
and type of collision.
Based on the severity and type of collision, the
side airbag inflator on the crash side of the
vehicle may be triggered, releasing a quantity
of non-toxic gas. The inflating side airbag exits
through the seat seam into the space between
the occupant and the door. The side airbags
fully inflate in about 10 milliseconds. The side
airbag 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 posi-
tioned in the area where the side airbag in-
flates. This especially applies to children.
Supplemental Side Airbag 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 airbags, de-
42

pending on 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 airbag. The inflating side
curtain airbag pushes the outside edge of the
headliner out of the way and covers the win-
dow. The airbag inflates in about 30 ms (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
airbag inflates. This especially applies to chil-
dren. The side curtain airbag is only about
3-1/2 in (9 cm) thick when it is inflated.
Because airbag sensors estimate deceleration
over time, vehicle speed and damage are not
good indicators of whether or not an airbag
should have deployed.
NOTE:
In a rollover the pretensioners, and/or SAB
and SABIC airbags may deploy on both
sides of the vehicle.Front and Side Impact Sensors
In front and side impacts, impact sensors can
aid the ORC in determining appropriate re-
sponse to impact events. Additional sensors in
the ORC determine the level of airbag deploy-
ment and provide verification.
Enhanced Accident Response System
In the event of an impact causing airbag de-
ployment, if the communication network re-
mains 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. If a Deployment Occurs
The Advanced Front Airbags are designed to
deflate immediately after deployment.
NOTE:
Front and/or side airbags will not deploy in
all collisions. This does not mean some-
thing is wrong with the airbag system.
If you do have a collision which deploys the
airbags, any or all of the following may occur:
•
The nylon airbag 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 gymna-
sium 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.

Airbag Warning LightYou will want to have the airbags
ready to inflate for your protection
in a collision. The airbag system is
designed to be maintenance free,
if any of the following occurs, have
an authorized dealer service the
airbag system immediately.
• The Airbag Warning Light does not come on
during the four to eight seconds when the
ignition switch is first turned to the ON/RUN
position.
• The Airbag Warning Light remains on after
the four to eight-second interval.
• The Airbag Warning Light comes on intermit-
tently or remains on while driving. NOTE:
If the speedometer, tachometer, or any en-
gine related gauges are not working, the
Occupant Restraint Controller (ORC) may
also be disabled. The airbags may not be
ready to inflate for your protection. Promptly
check the fuse block for blown fuses. Refer
to the label located on the inside of the fuse
block cover for the proper airbag fuses. See
your authorized dealer if the fuse is good.
Event Data Recorder (EDR)This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR is
to record, in certain crash or near crash-like
situations, such as an air bag deployment or
hitting a road obstacle, data that will assist in
understanding how a vehicle’s systems per- formed. The EDR is designed to record data
related to vehicle dynamics and safety systems
for a short period of time, typically 30 seconds
or less. The EDR in this vehicle is designed to
record such data as:
•
How various systems in your vehicle were
operating;
• Whether or not the driver and passenger
safety belts were buckled/fastened;
• How far (if at all) the driver was depressing
the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better under-
standing of the circumstances in which crashes
and injuries occur.

Safety Checks You Should Make
Inside the Vehicle
Seat Belts
Inspect the belt system periodically, checking
for cuts, frays, and loose parts. Damaged parts
must be replaced immediately. Do not disas-
semble or modify the system.
Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies must
be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing,
etc.). If there is any question regarding belt or
retractor condition, replace the belt.Airbag Warning Light
The light should come on and remain on for four
to eight seconds as a bulb check when the
ignition switch is first turned ON. If the light is
not lit during starting, see your authorized
dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by
an authorized dealer.
Defroster
Check operation by selecting the defrost mode
and place the blower control on high speed.
You should be able to feel the air directed
against the windshield. See your authorized
dealer for service if your defroster is inoper-
able.Floor Mat Safety Information
Always use floor mats designed to fit the foot
well of your vehicle. Use only floor mats that
leave the pedal area unobstructed and that are
firmly secured so that they cannot slip out of
position and interfere with the pedals or impair
safe operation of your vehicle in other ways.
WARNING!
Pedals that cannot move freely can cause
loss of vehicle control and increase the risk of
serious personal injury.
•
Always make sure that floor mats are prop-
erly attached to the floor mat fasteners.
• Never place or install floor mats or other
floor coverings in the vehicle that cannot be
properly secured to prevent them from
moving and interfering with the pedals or
the ability to control the vehicle.
(Continued)
56

WARNING!(Continued)
• Never put floor mats or other floor cover-
ings on top of already installed floor mats.
Additional floor mats and other coverings
will reduce the size of the pedal area and
interfere with the pedals.
• Check mounting of mats on a regular basis.
Always properly reinstall and secure floor
mats that have been removed for cleaning.
• Always make sure that objects cannot fall
into the driver foot well while the vehicle is
moving. Objects can become trapped un-
der the brake pedal and accelerator pedal
causing a loss of vehicle control.
(Continued)WARNING!(Continued)
• If required, mounting posts must be prop-
erly installed, if not equipped from the fac-
tory.
Failure to properly follow floor mat installation
or mounting can cause interference with the
brake pedal and accelerator pedal operation
causing loss of control of the vehicle.
Periodic Safety Checks You Should
Make Outside the Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread.
Inspect the tread and sidewall for cuts and
cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper
pressure. Lights
Have someone observe the operation of exte-
rior lights while you work the controls. Check
turn signal and high beam indicator lights on
the instrument panel.
Door Latches
Check for positive closing, latching, and lock-
ing.
Fluid Leaks
Check area under vehicle after overnight park-
ing for fuel, engine coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or if
fuel, power steering fluid, or brake fluid leaks
are suspected, the cause should be located
and corrected immediately.
