Advanced Front Air Bag Features
The Advanced Front Air Bag 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.
WARNING!
•No objects should be placed over or near the air
bag on the instrument panel, because any such
objects could cause harm if the vehicle is in a
collision severe enough to cause the air bag to
inflate.(Continued)

WARNING! (Continued)
•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.
•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, citizen band radios,
etc.
Supplemental Seat-Mounted Side Air Bags (SAB)
Supplemental Seat-Mounted Side Air Bags (SAB) provide
enhanced protection to help protect an occupant during a
side impact. The SAB are marked with an air bag label
sewn into the outboard side of the front seats.When the air bag deploys, it opens the seam between the
front and side of the seat’s trim cover. Each air bag
deploys independently; a left side impact deploys the left
air bag only and a right-side impact deploys the right air
bag only.

Supplemental Side Air Bag Inflatable Curtains (SABIC)
may offer side-impact protection to front and rear seat
outboard occupants in addition to that provided by the
body structure. Each air bag features inflated chambers,
placed adjacent to the head of each outboard occupant,
that reduce the potential for side-impact head injuries.
The SABIC deploy downward, covering both windows
on the impact side.NOTE:Air Bag covers may not be obvious in the
interior trim, but they will open during air bag deploy-
ment.

The system includes side impact sensors that are cali-
brated to deploy the Seat-Mounted Side Air Bags (SAB)
and SABIC during impacts that require air bag occupant
protection.
WARNING!
•Your vehicle is equipped with left and right
SABIC, do not stack luggage or other cargo up
high enough to block the location of the SABIC.
The area where the side curtain air bag is located
should remain free from any obstructions.
•Do not use accessory seat covers or place objects
between you and the SAB; the performance could
be adversely affected and/or objects could be
pushed into you, causing serious injury.(Continued)
WARNING! (Continued)
•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 perma-
nent attachments (bolts or screws) for installation
on the vehicle roof. Do not drill into the roof of the
vehicle for any reason.
Supplemental Driver Side Knee Air Bag
The Supplemental Driver Side Knee Air Bag provides
enhanced protection and works together with the Driver
Advanced Front Air Bag during a frontal impact.
Knee Impact Bolster
The Knee Impact Bolster helps protect the knees of the
passenger side front passenger by positioning the pas-
senger for the best interaction with the Advanced Front
Air Bags.
42 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Along with seat belts and pretensioners, Advanced Front
Air Bags work with the Supplemental Driver Side Knee
Air Bag and the passenger side knee bolster to provide
improved protection for the driver and front passenger.
Seat-Mounted Side Air Bags (SAB) and Supplemental
Side Air Bag Inflatable Curtains (SABIC) 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, Supplemen-
tal Driver Side Knee Air Bag, Supplemental Side Air Bag
Inflatable Curtain (SABIC), Supplemental Seat-MountedSide Air Bags (SAB), 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
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 or side
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,
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 43

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.
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 theON/RUN or START position. If the key is in the OFF/
LOCK 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
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

noted that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction.
WARNING!
Ignoring the Air Bag Warning Light in your instru-
ment panel could mean you won’t have the air bags
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.
Driver And Passenger Advanced Front Air Bag
Inflator Units
The Driver and Passenger Advanced Front Air Bag
Inflator Units are located in the center of the steering
wheel and on the right side of the instrument panel.
When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A largequantity of non-toxic gas is generated to inflate the
Advanced Front Air Bags. Different air bag 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 air bags inflate to their full size. The air bags fully
inflate in about 50 to 70 milliseconds. This is about half of
the time it takes to blink your eyes. The air bags then
quickly deflate while helping to restrain the driver and
front passenger.
The Advanced Front Air Bag gas is vented through the
vent holes in the sides of the air bag. In this way, the air
bags do not interfere with your control of the vehicle.Supplemental Driver Side Knee Air Bag Inflator
Unit
The Supplemental Driver Side Knee Air Bag unit is
located in the instrument panel trim beneath the steering
column. When the ORC detects a collision requiring the
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 45

air bag, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the Supplemental
Driver Side Knee Air Bag. The trim cover separates and
folds out of the way allowing the air bag to inflate to the
full size. The air bag fully inflates in about 15 to 20
milliseconds. The Supplemental Driver Side Knee Air
Bag gas is vented through small vent holes in the side of
the air bag.
Supplemental Seat-Mounted Side Air Bag (SAB)
Inflator Units
The Supplemental Seat-Mounted Side Air Bags (SAB) are
designed to activate only in certain side collisions.
The ORC determines if a side collision requires the side
air bags to inflate, based on several factors, including the
severity and type of collision.
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 ofnon-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 Supplemental Side Air Bag Inflatable Curtain
(SABIC), 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
46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

the outside edge of the headliner out of the way and
covers the window. The air bag inflates in about 30
milliseconds (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 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.
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.
After the event occurs, when the system is active, the
message Fuel Cutoff See Handbook is displayed.

Carefully check the vehicle for fuel leaks in the engine
compartment and on the ground near the engine com-
partment and fuel tank before resetting the system and
starting the engine.System Reset Procedure
After an impact causing air bag deployment, the left and
right turn signal lights, located in the instrument panel
cluster, will both be blinking, until the ignition is turned
off. In order to move your vehicle to the side of the road
you must follow the system reset procedure.
