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.
The front airbags have a multistage inflator design. This
may allow the airbag to have different rates of inflation
that are based on collision severity and occupant size.
This vehicle is also equipped with window bags to
protect the driver, front, and rear passengers sitting next
to a window. The window bags are located above the side
windows. Their covers are also labeled SRS AIRBAG.
NOTE:Airbag covers may not be obvious in the interior
trim, but they will open to allow airbag deployments.WARNING!
•Do not put anything on or around the front airbag
covers or attempt to manually open them. You may
damage the airbags and you could be injured
because the airbags are no longer functional.
These protective covers for the airbag cushions are
designed to open only when the airbags are inflat-
ing.
•Your vehicle is equipped with window bags. Do
not stack luggage or other cargo up high enough to
block the location of the window bag. The area
where the window bag is located should remain
free from any obstructions.

•Also, the ORC turns on the Airbag Warning
Light in the instrument cluster for six to
eight seconds for a self-check when the
ignition is first turned on. After the self-
check, the Airbag Warning Light will turn off. 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 detects a
collision requiring the airbags, 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. The steer-
ing 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 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.

has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper 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.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility tomaintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
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
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
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 tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.25. Airbag Warning Light
The airbag indicator light illuminates and re-
mains lit for six to eight seconds when the
ignition is first turned ON. If the light does not
come on when the ignition is first turned on, or
the light stays on or comes on while driving, have the
airbag system checked by an authorized dealer.
26. 4WD Indicator
The 4WD indicator light illuminates when the
transfer case is in 4WD position.
27. SVC (Service) 4WD Indicator
The SVC 4WD light will illuminate when the
ignition key is turned to the ON position and
will stay on for two seconds. If the light stays
on or comes on during driving, it means that
the 4WD system is not functioning properly and that
service is required.

FOUR-WHEEL DRIVE OPERATION
NV 140 Transfer Case Operating
Information/Precautions — If Equipped
The NV 140 is a single speed (HI range only) transfer case
which provides convenient full-time four-wheel drive.
No driver interaction is required.
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference in tire size can cause damage to the
transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
NV 244 Generation II Transfer Case Operating
Information/Precautions — If Equipped
The NV 244 Generation II is an electric-shift transfer case
and is operated by the 4WD Control Switch, which is
located on the instrument panel.
The NV 244 Generation II transfer case provides four
mode positions - Normal four-wheel drive (4WD) high
range, four-wheel drive lock (4WD LOCK) range, four-
wheel drive low (4WD LOW) range, and NEUTRAL.
This transfer case is equipped with an inter-axle differ-
ential that allows driving the vehicle in the normal
all-wheel drive position (4WD) at all times on any given
road surface, including dry, hard-surfaced roads. The
4WD mode allows the front and rear wheels to rotate at
different speeds. This eliminates driveline binding and
component wear normally associated with driving the
vehicle in the 4WD LOCK position on dry, hard-surfaced
298 STARTING AND OPERATING

WARNING!
Always engage the parking brake when powering
down the vehicle if theSVC 4WD Warning Light” is
illuminated. Not engaging the parking brake may
allow the vehicle to roll, which may cause personal
injury.
NOTE:Do not attempt to make a shift while only the
front or rear wheels are spinning. The NV 244 Generation
II transfer case is not equipped with a synchronizer and
therefore the front and rear driveshaft speeds must be
equal for the shift to take place. Shifting while only the
front or rear wheels are spinning can cause damage to the
transfer case.When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 4WD or
4WD LOCK positions at a given road speed. Take care
not to overspeed the engine and do not exceed 25 mph
(40 km/h).
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference in tire size can cause damage to the
transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
300 STARTING AND OPERATING

WARNING!
•Always fully apply the parking brake when leav-
ing your vehicle, or the vehicle may roll and cause
damage or injury. Also be certain to leave an
automatic transmission in PARK. Failure to do so
may cause the vehicle to roll and cause damage or
injury.
•Be sure the parking brake is fully disengaged
before driving, failure to do so can lead to brake
failure and an accident.
•Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Do not leave the keys
in the ignition. A child could operate power win-
dows, other controls, or move the vehicle.
ANTI-LOCK BRAKE SYSTEM
The Anti-Lock Brake System (ABS) is designed to aid the
driver in maintaining vehicle control under adverse
braking conditions. The system operates with a separate
computer to modulate hydraulic pressure, to prevent
wheel lock-up and help avoid skidding on slippery
surfaces.
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!
Significant over or under-inflation of tires or mixing
sizes of tires or wheels on the vehicle can lead to loss
of braking effectiveness.

Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. (Refer to the paragraph on
“Tread Wear Indicators”). Refer to the “Tire and Loading
Information” placard for the size designation of your tire.
The service description and load identification will be
found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability.
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 sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspen-
sion 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.
