Driver and Front Passenger Supplemental
Restraint System - Airbag
This vehicle has airbags for both the driver and front
passenger as a supplement to the seat belt restraint
systems. The driver’s front airbag is mounted in the
center of the steering wheel. The passenger’s front airbag
is mounted in the instrument panel, above the glove
compartment. The words SRS AIRBAG are embossed on
the airbag covers.
NOTE:The front airbags are certified to the Federal
regulations that allow less forceful deployment in low
speed collisions.
The front airbags have a multi stage inflator design. This
may allow the airbag to have different rates of inflation
that are based on collision severity and occupant size.

How The Airbag System Works

TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. Based on the level of collisionseverity, the front control module determines the
proper rate of inflation. The front airbag inflators are
designed to provide different rates of airbag inflation.
•The ORC may modify the rate of inflation based on the
occupant size provided by the Occupant Classification
Module.
•The ORC will not detect side, roll over, or rear impacts.
•The ORC monitors the readiness of the electronic parts
of the system whenever the ignition switch is in the
START or RUN positions. These include all of the
items listed above except the steering wheel and
column, instrument panel and passenger knee bol-
sters. If the key is in the OFF position, in the ACC
position, or not in the ignition, the airbags are not on
and will not inflate.

Also, the ORC turns on the AIRBAG warning
light and PAD indicator light in the center of
the instrument panel for 6 to 8 seconds for a
self-check when the ignition is first turned on.
After the self-check, the AIRBAG warning light will turn
off. The PAD indicator light will function normally (Refer
to“Passenger Airbag Disable (PAD) Indicator Light”in
this section). If the ORC detects a malfunction in any part
of the system, it turns on the AIRBAG warning light
either momentarily or continuously. A single chime will
sound if the light comes on again after initial start up.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 as

CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the power transfer unit
and/or the viscous coupling.
PARKING BRAKE
When the parking brake is applied with the ignition
switch on, the brake light in the instrument cluster will
turn on.
NOTE:This light only shows that the parking brake is
applied. It does not show the degree of brake application.Before leaving the vehicle, make sure that the parking
brake is fully applied and place the gear selector in the
Park position. To release the parking brake, pull out on
the parking brake release located on the left side of the
instrument panel.

When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as some
related motor noises. These noises are the system per-
forming its self check cycle to ensure that the ABS system
is working properly. This self check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).
ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
You also may experience the following when the brake
system goes into Anti-lock:
•The ABS motor running (it may continue to run for a
short time after the stop),
•the clicking sound of solenoid valves,
•brake pedal pulsations,
•and a slight drop or fall away of the brake pedal at the
end of the stop.
These are all normal characteristics of ABS.
WARNING!
The Anti-Lock Brake System contains sophisticated
electronic equipment that may be susceptible to
interference caused by improperly installed or high
output radio transmitting equipment. This interfer-
ence can cause possible loss of anti-lock braking
capability. Installation of such equipment should be
performed by qualified professionals.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.

WARNING!
•Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspen-
sion dimensions and performance characteristics,
resulting in changes to steering, handling, and brak-
ing of your vehicle. This can cause unpredictable
handling and stress to steering and suspension com-
ponents. You could lose control and have an accident
resulting in serious injury or death. Use only the tire
and wheel sizes with load ratings approved for your
vehicle.
•Never use a tire with a smaller load index or capacity,
other than what was originally equipped on your
vehicle. Using a tire with a smaller load index could
result in tire overloading and failure. You could lose
control and have an accident.
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Alignment And Balance
Poor suspension alignment may result in:
•Fast tire wear.
•Uneven tire wear, such as feathering and one-sided
wear.
•Vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.
280 STARTING AND OPERATING

Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
ALL WHEEL DRIVE (AWD)—IF EQUIPPED
CAUTION!
All Wheel Drive (AWD) vehicles must have the same
size and type tires on all wheel positions. Unequal
tire sizes must not be used. Unequal tire size may
cause failure of the power transfer unit and/or the
viscous coupling.
TIRE PRESSURE MONITOR SYSTEM—IF
EQUIPPED
The Tire Pressure Monitor System (TPM) system uses
wireless technology with wheel rim mounted electronic
sensors to monitor tire pressure levels (EXCLUDING
THE SPARE TIRE). Sensors, mounted to each wheel as
part of the valve stem, transmit tire pressure readings to
the Electronic Vehicle Information Center (EVIC) display
in the instrument cluster.
NOTE:It is particularly important, for you to check the
tire pressure in all of your tires regularly and too main-
tain the proper pressure.
When the appropriate conditions exist, the Electronic
Vehicle Information Center (EVIC) displays the following
messages.
STARTING AND OPERATING 281

Page 283 of 420

CAUTION!
The TPM system has been optimized for the original
equipment tires and wheels. TPM system pressures
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sen-
sor damage may result when using replacement
equipment that is not of the same size, type, and/or
style. After-market wheels can cause sensor damage.
Do not use tire sealant or balance beads if your
vehicle is equipped with a TPM system, as damage
to the sensors may result.
NOTE:
•The TPM system can inform the driver of a low tire
pressure condition of 26 psi [1.79 bars] (179 kPa) or
less, or high a tire pressure condition of 45 psi [3.10
bars] (310 kPa) or more.
•The TPM system is not intended to replace normal tire
care and maintenance, nor to provide warning of a tire
failure or condition.
•The TPM system should not be used as a tire pressure
gauge while adjusting your tire pressure.
CAUTION!
After inspecting or adjusting the tire pressure al-
ways reinstall the valve stem cap, if equipped. This
will prevent moisture and dirt from entering the
valve stem, which could damage the wheel rim
sensor.

CAUTION!
To avoid damage to your vehicle or tires, observe the following
precautions:
•Because of restricted chain clearance between tires and
other suspension components, it is important that only
chains in good condition are used. Broken chains can cause
serious damage. Stop the vehicle immediately if noise
occurs that could indicate chain breakage. Remove the
damaged parts of the chain before further use.
•Install chains on the front wheels as tightly as possible and
then retighten after driving about1⁄2mile (0.8 km).•Do not exceed 45 mph (70 km/h).
•Drive cautiously and avoid severe turns and large bumps,
especially with a loaded vehicle.
•Do not use on rear wheels of All Wheel Drive (AWD)
vehicles.
•Do not drive for prolonged period on dry pavement.
•Observe the tire chain manufacturer’s instructions on the
method of installation, operating speed, and conditions for
use. Always use the lower suggested operating speed of the
chain manufacturer if different than the speed recom-
mended by the manufacture.
NOTE:In order to avoid damage to tires, chains, and
your vehicle do not drive for a prolonged period of time
on dry pavement. Observe the tire chain manufacturer’s
instructions on method of installation, operating speed,
and conditions for usage.
Always use the lower suggested operating speed if both
the chain manufacturer and vehicle manufacture suggest
a maximum speed. This notice applies to all chain
traction devices, including link and cable (radial) chains.
SNOW TIRES
Some areas of the country require the use of snow tires
during winter. Standard tires are of the all season type
and satisfy this requirement as indicated by the M+S
designation on the tire side wall.
If you need snow tires, select tires equivalent in size and
type to the original equipment tires. Use snow tires only
in sets of 4, failure to do so may adversely affect the
safety and handling of your vehicle.
