airbag inflation rates may be possible based on colli-
sion severity. The steering wheel hub trim cover, and
the upper passenger side of the instrument panel
separate and fold out of the way, as the bags inflate to
their full size. The bags fully inflate in about 50 - 70
milliseconds. This is about half of the time that it takes
to blink your eyes. The bags then quickly deflate while
helping to restrain the driver and front passenger. The
driver’s front airbag gas is vented through vent holes
in the sides of the airbag. The passenger’s front airbag
gas is vented through vent holes in the sides of the
airbag. In this way, the airbags do not interfere with
your control of the vehicle.
•TheKnee Impact Bolstershelp protect the knees of
the driver and the front passenger, and position every-
one for the best interaction with the front airbag.
•TheSupplemental Side Impact SRS Side Curtain
Airbagsare designed to activate only in certain sidecollisions. When the ORC (with side impact option)
detects a collision requiring the side curtain airbag to
inflate, it signals the inflators on the crash side of the
vehicle. A quantity of nontoxic gas is generated to
inflate the side curtain airbag. The inflating side cur-
tain 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
inches (9 cm) thick when it is inflated.
•TheSupplemental Front-Seat-Mounted Side Airbags
are designed to activate only in certain side collisions.
When the ORC (with side impact option) detects a
collision requiring the front-seat-mounted side airbag
to inflate, it signals the inflators on the crash side of the
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

To Set At A Desired Speed:
When the vehicle reaches the speed desired, push the
lever down and release (“SET DECEL”). Remove your
foot from the accelerator pedal and the vehicle will
operate at the selected speed.
NOTE:
•Speed control will only function in third, fourth, or
fifth gear when in the Autostick\2Mode (if equipped).
•The speed control may not engage if a different size
tire is installed on one wheel, such as the compact
spare tire.
To Deactivate:
The system will disable Electronic Speed Control without
erasing the memory if you:
•Softly tap the brake pedal.
•Depress the brake pedal.
•Pull the speed control lever toward you (“CANCEL”).
Pushing and releasing the (“ON/OFF”) button or turning
off the ignition erases the set speed from memory.
To Resume Speed:
If you deactivated the speed control without erasing the
set speed from memory and your vehicle speed is above
20 mph (32 km/h) you can resume the previous set
speed. To do so, push the lever up and release (“RESUME
ACCEL”), and then remove your foot from the accelera-
tor pedal.
To Vary the Speed Setting:
When the speed control is set, you can increase speed by
pushing up and holding the lever (“RESUME ACCEL”).
When the lever is released, a new set speed will be
established.
150 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replace-
ment or alternate tires and wheels allow the TPMS to
continue to function properly. (See page 355 for more
information.)CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use aftermarket tire sealants
or balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.

ALL WHEEL DRIVE — IF EQUIPPED
This feature provides full time All Wheel Drive (AWD)
with Anti-lock Brake System (ABS)/Traction Control.
The front wheels provide 38% of the torque, and the rear
wheels provide 62% of the torque. The system is auto-
matic with no driver inputs or additional driving skills
required.
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 front differential and/or
the transfer case.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the rear wheels to pull errati-
cally to the right or left. This phenomenon occurs when
there is a difference in the surface traction under the rear
(driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
wheels. You could lose control of the vehicle and
possibly have an accident. Accelerate slowly and
carefully whenever there is likely to be poor traction
(ice, snow, wet mud, loose sand, etc.).

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 equip-
ment. This interference can cause possible loss of anti-lock
braking capability. Installation of such equipment should be
performed by qualified professionals.
•Pumping of the Anti-Lock Brakes will diminish their effective-
ness and may lead to an accident. Pumping makes the stopping
distance longer. Just press firmly on your brake pedal when you
need to slow down or stop.
•Anti-lock system (ABS) cannot prevent the natural laws of
physics from acting on the vehicle, nor can it increase braking or
steering efficiency beyond that afforded by the condition of the
vehicle brakes and tires or the traction afforded.
•The ABS cannot prevent accidents, including those resulting
from excessive speed in turns, following another vehicle too
closely, or hydroplaning. Only a safe, attentive, and skillful
driver can prevent accidents.
•The capabilities of an ABS equipped vehicle must never be
exploited in a reckless or dangerous manner, which could jeop-
ardize the user’s safety or the safety of others.
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.
Anti-Lock Brake Light
The ABS light monitors the Anti-Lock Brake Sys-
tem. The light will come on when the ignition
switch is turned to the ON position and may stay on for
as long as four seconds.
If the ABS light remains on or comes on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not come on when the
Ignition switch is turned to the ON position, have the
bulb repaired as soon as possible.
326 STARTING AND OPERATING

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 ad-
equate 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
readings.
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.
352 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.
SELF-SEALING TIRES — IF EQUIPPED
A non-hardening viscous sealant applied to the inner
liner of each tire fills punctures up to 0.19 in. (5 mm) to
minimize the loss of air pressure. This contributes to the
safety of the vehicle by significantly reducing the prob-
ability of a roadside stop due to a flat tire.
TIRE CHAINS
Use only compact chains, or other traction aids that meet
SAE type “Class S” specifications. Chains must be the
proper size for the vehicle, as recommended by the chain
manufacturer. In addition, only install tire chains on
P215/65 R17 and P225/60 R18 size tires. The P245/45 R20
size tires do not provide adequate clearance for tire chains.
NOTE:Do not use tire chains on a compact spare tire.
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 rear wheels as tightly as possible and
then retighten after driving about
1\262mile (0.8 km).
•Do not exceed 30 mph (48 km/h).
•Drive cautiously and avoid severe turns and large bumps,
especially with a loaded vehicle.
•Use on Rear Wheels only.
•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 from the speed recommended
by the manufacture.

CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when us-
ing replacement equipment that is not of the same
size, type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use aftermarket tire
sealants or balance beads if your vehicle is
equipped with a TPMS, as damage to the sensors
may result.
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
•The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
•Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the
level to trigger illumination of the Tire Pressure Moni-
toring Telltale light.
