WARNING!
Using a seat belt extender when not needed can
increase the risk of injury in a collision. Only use
when the lap belt is not long enough when it is worn
low and snug, and in the recommended seating
positions. Remove and store the extender when not
needed.
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.Front Airbag Components

How The Airbag System Works
•
The Occupant Restraint Controller (ORC) determines
if a frontal collision is severe enough to require the
airbags to inflate. Based on the level of collision
severity, 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 warn-
ing 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 momen-
tarily 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.
•The Driver and Passenger Airbag/Inflator Units are
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
the 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.

•If the system detects a problem it will disable the
AutoStick mode and the transmission will return to
the automatic mode until the problem is corrected.
ALL WHEEL DRIVE — IF EQUIPPED
This feature provides full time, on-demand, All Wheel
Drive (AWD). The system is automatic with no driver
inputs or additional driving skills required. Under nor-
mal driving conditions, the front wheels provide most of
the traction. If the front wheels begin to lose traction,
power is shifted automatically to the rear wheels. The
greater the front wheel traction loss, the greater the
power transfer to the rear wheels.
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.
266 STARTING AND OPERATING

•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.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason, the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE: Increased noise levels at the end of the steering
wheel travel are considered normal and does not indicate
that there is a problem with the power steering system.
Upon initial start-up in cold weather, the power steering
pump may make noise for a short period of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and does not in any
way damage the steering system.

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 suspension
dimensions and performance characteristics, result-
ing in changes to steering, handling, and braking of
your vehicle. This can cause unpredictable handling
and stress to steering and suspension components.
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.
290 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 (TPMS) 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 291

1,2,3, OR 4 TIRE(S) LOW PRESSURE
Low tire pressure levels of 26 psi [1.79 bars] (179 kPa) or
less detected in one or more tires.
Inspect all tires for proper inflation pressure, once the
proper tire pressure has been set, the TPMS system
warning will reset automatically when the vehicle has
been driven for at least 2 minutes at or above 20 mph (32
km/h).
CHECK TPM SYSTEM
The Tire Pressure Monitor System (TPMS) system re-
quires service.
See your authorized dealer for service.
CAUTION!
The TPMS system has been optimized for the origi-
nal equipment tires and wheels. TPMS system pres-
sures have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor 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 TPMS
system, as damage to the sensors may result.
NOTE:
•The TPMS system can inform the driver of a low tire
pressure condition of 26 psi [1.79 bars] (179 kPa) or
less.
