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.
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.
•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.

WARNING!(Continued)
•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) may
provide enhanced protection to help protect an occupant
during a side impact. The SAB is 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 Curtain
(SABIC)
SABIC air bags may offer side-impact and vehicle roll-
over 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 down-
ward, covering both windows on the impact side.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 73

NOTE:
•Air Bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
• Being too close to the SAB and SABIC air bags during
deployment could cause you to be severely injured or
killed.
• Should a vehicle rollover occur, the pretensioners
and/or SAB and SABIC air bags on both sides of the
vehicle may deploy.
The system includes side impact sensors that are cali-
brated to deploy the Supplemental SAB and SABIC air
bags during impacts that require side 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.
• 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.
74 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Always sit upright as possible with your back against the
seat back, use the seat belts properly, and use the
appropriate sized child restraint, infant restraint or
booster seat recommended for the size and weight of the
child.
SAB and SABIC air bags are a supplement to the seat belt
restraint system. Occupants, including children who
are up against or very close to SAB or SABIC air bags can
be seriously injured or killed. Occupants, especially
children, should not lean on or sleep against the door,
side windows, or area where the SAB or SABIC air bags
inflate, even if they are in an infant or child restraint.
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 Bag.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.
The Supplemental Driver Side Knee Air Bag provides
enhanced protection and works together with the Driver
Advanced Front Air Bag during a frontal impact.

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, SABIC air
bags, SAB air bags, 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 Knee
Air Bag are designed to provide additional protection by
supplementing the seat belts in certain frontal collisions
depending on several factors, including the severity andtype 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 and Supplemental Driver
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,
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.
76 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 77

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 large
quantity of non-toxic gas is generated to inflate theAdvanced Front Air Bags. Different air bag inflation rates
are possible, based on several factors, including 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 Seat-Mounted Side Air Bag (SAB)
Inflator Units
The Supplemental Seat-Mounted Side Air Bags are de-
signed to activate only in certain side collisions.
