WARNING!
Ignoring the AIRBAG warning light in your instru-
ment panel could mean you won’t have the airbags
to protect you in a collision. If the light does not
come on, stays on after you start the vehicle, or if it
comes on as you drive, have the airbag system
checked right away.
•TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC and
impact sensors detects a collision requiring the air-
bags, it signals the inflator units. A large quantity of
nontoxic gas is generated to inflate the front airbags.
Different airbag inflation rates may be possible based
on collision severity and occupant size. The steering
wheel hub trim cover and the upper right side of the
instrument panel separate and fold out of the way asthe airbags inflate to their full size. The airbags fully
inflate in about 50–70 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 driver’s and passenger’s front airbag gas is vented
through the airbag material towards the instrument
panel. In this way the airbags do not interfere with
your control of the vehicle.•TheSide Impact SRS Side Curtain Bagsare designed
to activate only in certain side collisions. When the
ORC and the side impact sensors (with side impact
option) detects a collision requiring the window bags
to inflate, it signals the inflators on the crash side of the
vehicle. A quantity of nontoxic gas is generated to
inflate the window bag. The inflating window bag
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 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 window bag
inflates. This especially applies to children. The win-
dow bag is only about 3
12inches (9 cm) thick when it
is inflated.
•When the ORC and the side impact sensors (with side
impact option) detects a collision requiring theDriver
Inflatable Knee Blocker,it signals the inflator unit. A
quantity of nontoxic gas is generated to inflate the
Driver Inflatable Knee Blocker. The Driver Inflatable
Knee Blocker inflates rearward towards the driver’s
knees to help protect the knees and position you for
the best interaction with the front airbag. The Driver
Inflatable Knee Blocker fully inflates in about 50
milliseconds, this is only about half of the time it takes
you to blink your eyes. It then quickly deflates while
helping to protect the driver’s knees.
•TheKnee Impact Bolstershelp protect the knees, and
position everyone for the best interaction with the
front airbag.
•If your vehicle contains a Passenger Airbag Disable
indicator light, it will be equipped with theOccupant
Classification System (OCS).The OCS system will
classify an occupant into a size category based on
sensor readings from within the seat cushion. Occu-
pants should try to remain in a normally seated
position. If the occupant’s weight is transferred to
another object in the vehicle (i.e. feet on the dash-
board), the OCS may not be able to properly approxi-
mate occupant size. Furthermore, the occupant size
may appear to increase or decrease due to objects
hanging on the seat, other passengers pushing on the
seat, or objects lodged underneath the seat. Ensure
that the front passenger seat back does not touch
anything placed on the back seat because this can also

teenagers and some small adults, depending on size, the
airbag may or may not be enabled in the event of a
collision. Both drivers and passengers should always use
the PAD indicator light as an indication if the front
passenger is properly positioned or not. If the PAD
indicator light comes on when an adult is in the passen-
ger seat, have the passenger re-position themselves in the
seat until the light goes out.
Remember, if the PAD indicator light is illuminated the
passenger front airbag will not inflate. For almost all
properly installed child restraints, the “PAD Indicator
Light” will be illuminated indicating that the front pas-
senger airbag is turned off and will not inflate. If the
“PAD Indicator Light” is not illuminated, DO NOT
assume the airbag is turned off and move the child
restraint to the rear seat. A deploying passenger airbag
can cause death or serious injury to a child in a rear
facing infant seat.NOTE:Even though this vehicle is equipped with an
Occupant Classification System, children 12 years and
under should always ride buckled up in a rear seat in an
appropriate child restraint.
•TheOccupant Classification Module (OCM) — If
Equippedis located beneath the front passenger seat.
The OCM classifies the occupant into one of three size
categories based on the input from the Bladder Assem-
bly and Belt Tension Sensor. The size categories in-
clude empty, child, and adult. The OCM sends the
Occupant Classification to the ORC to identify if a
front passenger airbag is allowed. If a fault is present,
the AIRBAG warning light is illuminated.
•ThePassenger Airbag Disabled (PAD) Indicator
Light — If Equippedindicates to the driver and
passenger when the airbag is turned OFF in the
presence of a properly seated occupant. When the PAD
indicator light is illuminated, the airbag is OFF. Also,
66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

when the Occupant Classification System detects ei-
ther an empty seat or a weight less than the predeter-
mined occupant threshold, the ORC will not illumi-
nate the PAD indicator light even though the airbag is
turned OFF. When the OCS system detects an adult the
PAD indicator light will be off, and the airbag will be
enabled.
•TheBelt Tension Sensor (BTS) — If Equippedis
located at the outboard passenger lap belt anchor. The
BTS generates a signal based on outboard lap belt
tension. This signal is sent to the OCM to ensure that
the resultant bladder pressure increase due to applied
lap belt tension does not cause a small occupant to be
classified as a larger occupant.
•TheBladder Assembly — If Equippedis located
beneath the seat cushion foam. The pressure sensor
sends a signal to the OCM.
The front passenger seat assembly contains critical com-
ponents that affect the front passenger airbag deploy-
ment. Correctly functioning front passenger seat compo-
nents are critical for the Occupant Classification System
(OCS) to properly classify the front passenger and calcu-
late the proper airbag deployment. Do not make any
modifications to the front passenger seat components,
assembly, or to the seat cover.

If A Deployment Occurs
The airbag system is designed to deploy the airbags
when the ORC and impact sensors detect a moderate-to-
severe collision, to help restrain the vehicle passengers,
and then immediately deflate.
NOTE:A collision that is not severe enough to need
airbag protection will not activate the system. This does
not mean something is wrong with the airbag system.
If you do have a collision which deploys the airbags, any
or all of the following may occur:
•The nylon airbag material may sometimes cause abra-
sions and/or skin reddening to the driver and front
passenger as the airbags 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 airbags deflate you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the nontoxic gas used for airbag
inflation. These airborne particles may irritate the skin,
eyes, nose, or throat. If you have skin or eye irritation,
rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation continues,
see your doctor. If these particles settle on your
clothing, follow the garment manufacturer’s instruc-
tions for cleaning.
•It is not advisable to drive your vehicle after the
airbags have deployed. If you are involved in another
collision, the airbags will not be in place to protect you.

•The Traction Control will make buzzing or clicking
sounds when in operation.
REAR PARK ASSIST SYSTEM — IF EQUIPPED
This system is used to help drivers determine if an
obstacle is in the way of the vehicle while it is backing up
in addition to the use of inside rearview and outside
mirrors.
When the driver selects Reverse the system scans for
objects behind the vehicle using four sensors located in
the rear bumper. Objects can be detected from up to 59
inches (150 cm). A warning display above the rear
window provides both visible and audible warnings
indicating the distance of the object.The warning display contains two sets of yellow and red
LEDs, one set to warn of obstacles behind the left rear of
the vehicle and the other set to warn of obstacles behind
the right rear of the vehicle. The driver can view the LEDs
either through the rear view mirror or by looking at the
display above the rear window.

WARNING!
•Drivers must be careful when backing up even when
using the Rear Park Assist System. Always check
carefully behind your vehicle, and be sure to check
for pedestrians, animals, other vehicles, obstruc-
tions, or blind spots before backing up. You are
responsible for the safety of your surroundings and
must continue to pay attention while backing up.
Failure to do so can result in serious injury or death.
•Before using the Rear Park Assist System, it is
strongly recommended that the ball mount and hitch
ball assembly be disconnected from the vehicle
when the vehicle is not used for towing. Failure to do
so can result in injury or damage to vehicles or
obstacles because the hitch ball will be much closer
to the obstacle than the rear fascia when the warning
display turns the red LEDs ON. Also, the sensors
could detect the ball mount and hitch ball assembly,
depending on its size and shape, giving a false
indication that an obstacle is behind the vehicle.
CAUTION!
•To avoid vehicle damage the Rear Park Assist
System should only be used as a parking aid and
is unable to recognize every obstacle, including
small objects. Parking curbs might be temporarily
detected or not detected at all. Obstacles located
above or below the sensors will not be detected
when they are in close proximity to the rear of the
vehicle.
•To avoid vehicle damage the vehicle must be
driven slowly when using the Rear Park Assist
System to be able to stop in time when an obstacle
is detected. It is recommended that the driver look
over his/her shoulder when using the Rear Park
Assist System.
