26. Malfunction Indicator Light
This light is part of an onboard diagnostic system
which monitors the emissions and engine control
system. If the vehicle is ready for emissions
testing the light will come on when the ignition is first
turned on and remain on, as a bulb check, until the
engine is started. If the vehicle is not ready for emissions
testing the light will come on when the ignition is first
turned on and remain on for 15 seconds, then blink for 10
seconds, and remain on until the vehicle is started. If the
bulb does not come on during starting, have the condi-
tion investigated promptly.If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and driveability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.

FOUR-WHEEL DRIVE OPERATION
NV 144 Transfer Case Operating
Information/Precautions
The NV 144 is an electric shift transfer case and is
operated by the Four-Wheel-Drive (4WD) Control
Switch, which is located on the instrument panel.
The NV 144 transfer case provides 2 mode positions:
All-Wheel Drive (AWD) and 4-Wheel-Drive LOCK.
The NV 144 transfer case is designed to be driven in for
AWD for normal street and highway conditions (all road
surfaces roads).
When additional traction is required, the transfer case
4LOCK position can be used to lock the front and rear
driveshafts together and force the front and rear wheelsto rotate at the same speed. This is accomplished by
rotating the 4WD Control Switch to the 4LOCK position
- see Shifting Procedure section for specific shifting
instructions. The 4LOCK position is designed for loose,
slippery road surfaces only. Driving in the 4LOCK posi-
tion on dry hard surfaced roads may cause increased tire
wear and damage to the driveline components.Transfer Case Position Indicator Lights
Transfer case position indicator lights are located on the
instrument cluster, and indicate the current and desired
transfer case selection. If there are no indicator lights on
or flashing the transfer case position is All-Wheel Drive
(AWD).
The “SVC 4WD” warning light monitors the electric shift
4WD system. If this light remains on after engine start up
or illuminates during driving, it means that the 4WD
system is not functioning properly and that service is
required.
250 STARTING AND OPERATING

NOTE:The transfer case Neutral (N) position is to be
used for recreational towing only. See Recreational Tow-
ing section for specific procedures on shifting into and
out of Neutral (N).
Transfer Case Position Indicator Lights
Transfer case position indicator lights are located on the
instrument cluster. If there are no indicator lights on or
flashing the transfer case position is All-Wheel Drive
(AWD) and indicate the current and desired transfer case
selection (4HI⇔4LOCK).
The “SVC 4WD” warning light monitors the electric shift
4WD system. If this light remains on after engine start up
or illuminates during driving, it means that the 4WD
system is not functioning properly and that service is
required.
WARNING!
Always engage the parking brake when powering
down the vehicle if theService 4WDlight 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.
254 STARTING AND OPERATING

Life of Tire
The service life of a tire is dependent upon varying
factors including but not limited to:
•Driving style
•Tire pressure
•Distance driven
WARNING!
Tires and spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have an accident result-
ing in serious injury or death.
Keep unmounted 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 (see the paragraph on tread
wear indicators). Refer to the Tire and Loading Informa-
tion 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, han-
dling, and ride of your vehicle. We recommend that you
contact your original equipment or an authorized tire
dealer with any questions you may have on tire specifi-
cations or capability.
280 STARTING AND OPERATING

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light.” It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.CAUTION!
•Prolonged driving with the “Malfunction Indica-
tor Light” on could cause further damage to the
emission control system. It could also affect fuel
economy and driveability. The vehicle must be
serviced before any emissions tests can be per-
formed.
•If the “Malfunction Indicator Light” is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is loose, improperly
installed, or damaged. A loose fuel filler cap message will
be displayed in the instrument cluster. Tighten the gas
MAINTAINING YOUR VEHICLE 337

cap until aclickingsound is heard. This is an indication
that the gas cap is properly tightened. Press the odometer
reset button to turn the message off. If the problem
persists, the message will appear the next time the
vehicle is started. This might indicate a damaged cap. If
the problem is detected twice in a row, the system will
turn on the Malfunction Indicator Light (MIL). Resolving
the problem will turn the MIL light off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system is determined not ready
for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key actuated test
which you can use prior to going to the test station. To
check if your vehicle’s OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine. If you crank or start the engine, you
will have to start this test over.

WARNING!
Battery posts, terminals, and related accessories con-
tain lead and lead compounds. Always wash hands
after handling the battery.
To determine the battery charge, check the battery test
indicator (if equipped) on top of the battery. Refer to the
illustration.
CAUTION!
It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to the
negative post. Battery posts are marked (+) positive
and negative (-) and identified on the battery case.
Also, if a “fast charger” is used while battery is in the
vehicle, disconnect both vehicle battery cables be-
fore connecting the charger to battery. Do not use a
“fast charger” to provide starting voltage.
Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an Authorized Dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and a performance
test. Drive belt tension should also be checked at this
time.
