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.
• 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 may provide
enhanced protection to help protect an occupant during a
side impact. The Supplemental Seat-Mounted Side Air
Bag 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 protection to front
seat outboard occupants in addition to that provided by
the body structure. Each air bag features inflated cham-
bers placed adjacent to the head of each outboard occu-
pant that reduce the potential for side-impact head
injuries. The curtains 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 deployment. •
Being too close to the SAB and SABIC air bags during
deployment could cause you to be severely injured or
killed.
The system includes side impact sensors that are cali-
brated to deploy the side air bags during impacts that
require air bag occupant protection.
WARNING!
• 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.

WARNING!(Continued)
•Your vehicle is equipped with left and right
Supplemental Side Air Bag Inflatable Curtain
(SABIC), do not stack luggage or other cargo up
high enough to block the location of the SABIC.
The area where the SABIC is located should remain
free from any obstructions.
• 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.
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 chil-
dren, 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. 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.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and front passengers, and position front occupants
for the best interaction with the Advanced Front Air
Bags.
Along with seat belts and pretensioners, Advanced Front
Air Bags work with the knee impact bolsters to provide
improved protection for the driver and front passenger.

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 are designed to provide addi-
tional protection 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, side, or rollover collisions.The Advanced 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, 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.
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.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 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 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 (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 the severity and type of collision.
Based on the severity and type of collision, the side air
bag inflator on the crash side of the vehicle may be
triggered, releasing a quantity of non-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 SABIC air bags, depending 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 air bag. The inflating side curtain air bag pushes 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 only about
3.5 in (9 cm) thick when it is inflated.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 47

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.
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 nylon air bag 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 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
