THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 11

The Advanced Front Airbags have a multistage inflator
design. This allows the airbag to have different rates of
inflation based on the severity and type of collision.
This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Airbags based upon
seat position.
This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether
the driver or front passenger seat belt is fastened. The
seat belt buckle switch may adjust the inflation rate of the
Advanced Front Airbags.
This vehicle may also be equipped with Supplemental
Side Airbag Inflatable Curtains (SABIC) to protect the
driver, front, and rear passengers sitting next to a win-
dow. If the vehicle is equipped with SABIC airbags, they
are located above the side windows and their covers are
also labeled: SRS AIRBAG.NOTE:
•Airbag covers may not be obvious in the interior trim,
but they will open during airbag deployment.
•After any accident, the vehicle should be taken to an
authorized dealer immediately.
Airbag System Components
Your vehicle may be equipped with the following airbag
system components:
•Occupant Restraint Controller (ORC)
•Airbag Warning Light

54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•Supplemental Side Airbag Inflatable Curtains (SABIC)
•Front and Side Impact Sensors
•Front Seat Belt Pretensioners, Seat Belt Buckle Switch,
and Seat Track Position Sensors
Advanced Front Airbag Features
The Advanced Front Airbag system has multistage driver
and front passenger airbags. 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 (if equipped).
The first stage inflator is triggered immediately during an
impact that requires airbag 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
airbag on the instrument panel, because 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 covers for the airbag cushions are
designed to open only when the airbags are inflat-
ing.
•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 Side Airbag Inflatable Curtain
(SABIC) — If Equipped
SABIC airbags may offer side-impact protection to front
and rear seat outboard occupants in addition to that
provided by the body structure. Each airbag features
inflated chambers placed adjacent to the head of each
outboard occupant that reduce the potential for side-
impact head injuries. The curtains deploy downward,
covering both windows on the impact side.NOTE:Airbag covers may not be obvious in the interior
trim, but they will open during airbag deployment.
The system includes side impact sensors that are cali-
brated to deploy the side airbags during impacts that
require airbag occupant protection.

56 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Do not lean against the door or window. If your vehicle
has side airbags, and deployment occurs, the side airbags
will inflate forcefully into the space between you and the
door.
If the airbag system in this vehicle needs to be modified
to accommodate a disabled person, contact the Customer
Center. Phone numbers are provided underIf You Need
Assistance.
WARNING!
•Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions, the airbags won’t deploy at all.
Always wear your seat belts even though you have
airbags.
(Continued)
WARNING! (Continued)
•Being too close to the steering wheel or instrument
panel during Advanced Front Airbag deployment
could cause serious injury, including death. Air-
bags need room to inflate. Sit back, comfortably
extending your arms to reach the steering wheel or
instrument panel.
•Supplemental Side Airbag Inflatable Curtains
(SABIC) also need room to inflate. Do not lean
against the door or window. Sit upright in the
center of the seat.
Airbag Deployment Sensors And Controls
Occupant Restraint Controller (ORC)
TheORC is part of a Federally 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.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 59

Based on the impact sensor’s signals, a central electronic
ORC deploys the Advanced Front Airbags, SABIC air-
bags — if equipped, and front seat belt pretensioners —
if equipped, as required, depending on the severity and
type of impact.
Advanced Front Airbags 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 Airbags are not ex-
pected to reduce the risk of injury in rear, rollover, or side
collisions.
The Advanced Front Airbags 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 deceleration over
time, vehicle speed and damage by themselves are not
good indicators of whether or not an airbag should have
deployed.
Seat belts are necessary for your protection in all acci-
dents, and also are needed to help keep you in position,
away from an inflating airbag.
The ORC monitors the readiness of the electronic parts of
the airbag system whenever the ignition switch is in the
START or ON/RUN position. If the key is in the LOCK

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 Side Airbag Inflatable Curtain
(SABIC) Inflator Units — If Equipped
During collisions where the impact is confined to a
particular area of the side of the vehicle, the ORC may
deploy the SABIC airbags, 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 airbag. The inflating side curtain airbag pushes
the outside edge of the headliner out of the way and
covers the window. The airbag 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 airbag
inflates. This especially applies to children. 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.
Front And Side Impact Sensors — If Equipped
In front and side impacts, impact sensors can aid the
ORC in determining appropriate response to impact
events.

PARKSENSEREAR PARK ASSIST — IF
EQUIPPED
The ParkSense Rear Park Assist system provides visual
and audible indications of the distance between the rear
fascia and a detected obstacle when backing up, e.g.
during a parking maneuver. Refer to ParkSense System
Usage Precautions for limitations of this system and
recommendations.
ParkSense will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSense can be active only when the shift lever is in
REVERSE. If ParkSense is enabled at this shift lever
position, the system will remain active until the vehicle
speed is increased to approximately 11 mph (18 km/h) or
above. The system will become active again if the vehicle
speed is decreased to speeds less than approximately
10 mph (16 km/h).
ParkSense Sensors
The four ParkSense sensors, located in the rear fascia/
bumper, monitor the area behind the vehicle that is
within the sensors’ field of view. The sensors can detect
obstacles from approximately 12 in (30 cm) up to 79 in
(200 cm) from the rear fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.
ParkSense Warning Display
The ParkSense Warning screen will only be displayed if
Sound and Display is selected from the Customer- Pro-
grammable Features section of the Electronic Vehicle
Information Center (EVIC). Refer to “Electronic Vehicle
Information Center (EVIC)/Personal Settings (Customer-
Programmable Features)” in “Understanding Your In-
