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 deter-
mined 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! (Continued)
•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
permanent attachments (bolts or screws) for instal-
lation on the vehicle roof. Do not drill into the roof
of the vehicle for any reason.
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 air bags deploy
downward, covering both windows on the impact side.NOTE:
•Should a vehicle rollover occur, the pretensioners
and/or SABIC air bags on both sides of the vehicle
may deploy.
•Air Bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
•Being too close to the side 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 side air bag occupant protection.
•If your vehicle is equipped with left and right Supple-
mental 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.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 63

•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.
•If 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 permanent attach-
ments (bolts or screws) for installation on the vehicle
roof. Do not drill into the roof of the vehicle for any
reason.
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.
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 Side Air Bag Inflatable Curtain (SABIC), and front seat
belt pretensioners, as required, depending on the severity
and type of impact.
64 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Advanced Front Air Bags are designed to provide addi-
tional protection by supplementing the seat belts in
certain frontal collisions depending on 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 SABIC will not deploy in all side collisions. SABIC
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 crashes,
and also are needed to help keep you in position, away
from an inflating air bag.
The ORC also monitors the readiness of the electronic
parts of the air bag system whenever the ignition switch
is in the START or ON/RUN positions. If the key is in the
LOCK 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.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 65

•Occupant Classification Module (OCM)
The OCM is located beneath the front passenger seat. The
OCM classifies the occupant into categories based on the
measurements made by the seat weight sensors. The
OCM communicates with the ORC. The ORC uses the
occupant category to determine whether the passenger
Advanced Front Air Bag should be turned off. It also
determines the rate of air bag inflation during a collision.
•Weight Sensors
Your vehicle has four Weight Sensors located between the
seat and the floor pan. The weight sensors measure
applied weight and transfers that information to the
OCM.
•Passenger Air Bag Disable (PAD) Indicator Light
The PAD Indicator Light (an amber light located in the
center of the instrument panel) tells the driver and front
passenger when the passenger Advanced Front Air Bag is
turned off. The PAD Indicator light illuminates the words “PASS AIR BAG OFF” to show that the passenger
Advanced Front Air Bag will not inflate during a collision
requiring air bag deployment. When the right front
passenger seat is empty or when very light objects are
placed on the seat, the passenger air bag will not inflate
even though the PAD indicator light is not illuminated.
Indicator Light Location
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 67

Drivers and adult passengers should verify that the PAD
Indicator Light is not illuminated when an adult is riding
in the front passenger seat. If an adult occupant’s weight
is transferred to another part of the vehicle (like the door
or instrument panel), the weight sensors in the seat may
not properly classify the occupant. Objects lodged under
the seat or between the seat and the center console can
prevent the occupant’s weight from being measured
properly and may result in the occupant being improp-
erly classified. Ensure that the front passenger seatback
does not touch anything placed on the second row of
seats because this can also affect occupant classification.
Also, if you fold down the seats in the second row check
to be sure they don’t touch the front passenger seat.
If the front passenger seat is damaged in any way, it
should only be serviced by an authorized dealer. If the
seat is removed (or even if the seat attachment bolts are
loosened or tightened in any way), take the vehicle to an
authorized dealer.If there is a fault present in the air bag system, the Air Bag
Warning Light (a red light located in the center of the
instrument cluster directly in front of the driver) will be
turned on. This indicates that you should have an autho-
rized dealer service the system immediately. The Air Bag
Warning Light is turned on whenever there is a fault that
can affect the operation of the air bag system. If there is a
fault present in the PAD Indicator Light, the Air Bag
Warning Light will be illuminated to show that the
passenger Advanced Front Air Bag may be turned off
until the fault is cleared. If the Air Bag Warning Light is
illuminated, have an authorized dealer service the air bag
system immediately. If an object is lodged under the seat
and interferes with operation of the weight sensors, a
fault will occur which turns on both the PAD Indicator
Light and the Air Bag Warning Light. Once the lodged
object is removed, the fault will be automatically cleared
after a short period of time.
