NOTE:
²Steps 1 through 5 are requirements that must be met
prior to depressing the NEUTRAL selection button,
and must continue to be met until 1 second elapses
and the shift has been completed. If any of these
requirements (with the exception of 3 - key ON) are
not met prior to depressing the NEUTRAL button or
are no longer met during the 1 second time, then all of
the mode position indicator lights will flash continu-
ously until all requirements are met or until the
NEUTRAL button is released.
²The ignition key must be ON for a shift to take place
and for the position indicator lights to be operable. If
the key is not ON, the shift will not take place and no
position indicator lights will be on or flashing.
²Flashing NEUTRAL position indicator light indicates
that shift requirements have not been met.
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
despite the transmission position. The parking brake
should always be applied when the driver is not in
the vehicle.

NOTE: Before raising the wheel off the ground, make
sure that the jack will not damage surrounding truck
parts and adjust the jack position as required.
5. By rotating the wheel wrench clockwise, raise the
vehicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle unstable and cause an accident. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
6. Remove the wheel nuts and pull the wheel off. Install
the spare wheel and wheel nuts with the cone shaped end
of the nuts toward the wheel. Lightly tighten the nuts. To
avoid risk of forcing the vehicle off the jack, do not fully
tighten the nuts until the vehicle has been lowered.
7. Using the wheel wrench, finish tightening the nuts in
a crisscross pattern. Correct nut tightness is 120 to 160 ft
lbs (163 to 217 N´m). If in doubt about the correct
tightness, have them checked with a torque wrench by
your authorized dealer or at a service station.

To Stow the Flat or Spare
Turn the wheel so that the valve stem is down. Slide the
wheel retainer through the center of the wheel and
position it properly across the wheel opening.
For convenience in checking the spare tire inflation, stow
with the valve stem toward the rear of the vehicle.
Rotate the winch mechanism until the wheel is drawn
into place against the underside of the vehicle. Continue
to rotate until you feel the winch mechanism slip or click
three times. It cannot be overtightened. Push against the
tire several times to be sure it is firmly in place.
NOTE:To Stow the Flat or Spare: Wheel retainer does
not fit through the center of the aluminum wheel. The tire
must be stored in a safe manner in the bed of the truck.
JUMP±STARTING
WARNING!
²Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin or cloth-
ing. Don't lean over battery when attaching
clamps or allow the clamps to touch each other. If
acid splashes in eyes or on skin, flush the contami-
nated area immediately with large quantities of
water.
²A battery generates hydrogen gas which is flam-
mable and explosive. Keep flame or spark away
from the vent holes. Do not use a booster battery
or any other booster source with an output that
exceeds 12-Volts.
Check the Battery Test Indicator (if equipped). If a light or
bright colored dot is visible in the indicator, DO NOT
jump-start the battery.

FREEING A STUCK VEHICLE
If vehicle becomes stuck in snow, sand, or mud, it can
often be moved by a rocking motion. Move the shift lever
rhythmically between FIRST and REVERSE, while apply-
ing slight pressure to the accelerator.
The least amount of accelerator pedal pressure to main-
tain the rocking motion without spinning the wheels or
racing the engine is most effective. Allow the engine to
idle with the shift lever in NEUTRAL for at least one
minute after every five rocking-motion cycles. This will
minimize overheating and reduce the risk of transmis-
sion failure during prolonged efforts to free a stuck
vehicle.
EMERGENCY TOW HOOKS Ð IF EQUIPPED
Your vehicle may be equipped with emergency tow
hooks.

ONBOARD DIAGNOSTIC SYSTEM Ð 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 (MIL). 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 authorized dealer for service as
soon as possible.CAUTION!
²Prolonged driving with the MIL 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 performed.
²If the MIL is flashing while the engine is running,
severe catalytic converter 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 possibly loose, improp-
erly installed, or damaged. A loose fuel filler cap message
will be displayed in the instrument cluster. Tighten the
gas cap until a9clicking9sound 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
MAINTAINING YOUR VEHICLE 353

Page 356 of 449

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 MIL. Resolving the problem will turn the MIL
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 that require an Inspection and Mainte-
nance (I/M), this check verifies the Malfunction
Indicator Light (MIL) is functioning and is not on
when the engine is running, and that the OBD II system
is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system maynotbe ready if your vehicle was recentlyserviced, recently had a dead battery, or a battery replace-
ment. If the OBD II system should be 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 II 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.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see the MIL symbol come on as part of a normal bulb
check.

²Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, also keep the front of
the condenser clean.
²Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine coolant (antifreeze)
performance, poor gas mileage, and increased
emissions.
Brake System
Fluid Level Check Ð Brake Master Cylinder
The fluid level in the master cylinder should be checked
whenever the vehicle is serviced, or immediately if the
brake system warning light is on. If necessary, add fluid
to bring level to the full mark on the side of the reservoir
of the brake master cylinder. Be sure to clean the top of
the master cylinder area before removing the cap. With
disc brakes, fluid level can be expected to fall as the brakepads wear. Brake fluid level should be checked when
pads are replaced. If the brake fluid level is abnormally
low, check system for leaks.
Refer to ªFluids, Lubricants, and Genuine Partsº in this
section for the correct fluid type.
WARNING!
²Use of brake fluid that may have a lower initial
boiling point, or is unidentified as to specifica-
tions, may result in sudden brake failure during
hard prolonged braking. You could have an acci-
dent.
²Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
