RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the cellular phone being On in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the cellular phone antenna. This condition
is not harmful to the radio. If your radio performance
does not satisfactorily “clear” by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.
CLIMATE CONTROLS
The controls for the heating and ventilation system in this
vehicle consist of three rotary control knobs.
NOTE: For the HVAC to operate efficiently and reduce
the possibility of fog build up on the interior of the
windows, the air exhausters should be kept clear at all
times. The air exhausters are the slots located on the rear
tailgate.
Heater Only — If Equipped
In snowy weather, always clear the air inlet grille at the
base of the windshield before driving your vehicle.

Off Turning the rotary knob to this position shuts off the
blower motor and outside air will not come through
any outlet.
Recirculation Select this position when the outside air contains
smoke, odors, high humidity, or if rapid cooling is
desired. This feature allows for recirculation of
interior air only. Air flows through the panel outlets in
this mode. Also, a slight amount of airflow may be
noticed at the defrost outlet located at the base of the
windshield.
Panel Outside air flows through the air conditioning
system, and then through the outlets located in the
instrument panel. Also, a slight amount of airflow
may be noticed at the defrost outlet located at the base of
the windshield. Bi-Level
Outside air flows through the air conditioning
system, and then through the outlets located in the
instrument panel and those located on the floor. Also, a
slight amount of airflow may be noticed at the defrost
outlet located at the base of the windshield.

Mix Outside air comes from the floor and defrost out-
lets. This mode works best in cold or snowy con-
ditions. It allows you to stay comfortable while
keeping the windshield clear.
Defrost Outside air comes from the windshield outlets
with a small amount being directed through the
floor outlets. Use this setting when necessary to defrost
your windshield.
NOTE: For improved safety, the A/C compressor is
activated when “Mix” or “Defrost” modes are selected.
This is done to assist in drying the air and it will help in
keeping the windshield from fogging.Operating Tips
Summer Operation
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended.
Winter Operation
The air from the heater system will heat faster in cold
weather if you use lower blower speeds until the engine
warms up. When operating the system during the winter
months, make sure the air intake, located directly in front
of the windshield, is free of ice, slush, snow, or other
obstructions.

Window Fogging
In mild but rainy or humid weather, the windows might
fog on the inside. To clear the fog off all of the windows,
turn the mode control knob to the “Panel” position (with
snowflake). Adjust the temperature control and blower
speed to maintain comfort. Direct the panel outlets
toward the side windows. Interior fogging on the wind-
shield can be quickly removed by selecting the “Defrost”
position.

When frequent transmission shifting occurs while using
Overdrive, such as when operating the vehicle under
heavy load conditions (for example, in hilly terrain,
strong head winds, or trailer towing), turning off over-
drive will improve performance and extend transmission
life by reducing excessive shifting and heat buildup. Overdrive can be locked out by pressing the O/D OFF
switch located on the instrument panel. The O/D OFF
indicator light (on the switch) will illuminate to show
that the switch has been activated. When the indicator
light is on, Overdrive is locked out. Pressing the switch a
second time restores the Overdrive function. The lockout
feature is useful when towing a trailer or carrying a
heavy load.

ment or in mud and snow. Begins at a stop in low gear
with automatic upshift to 2nd gear. Will not shift to 3rd.
1 (First)
For hard pulling at low speeds in mud, sand, snow, or on
steep grades. Begins and stays in low gear with no
upshift. Provides engine compression braking at low
speeds.

Operating Instructions/Precautions
The transfer case provides four mode positions — two
(rear) wheel drive high range, four wheel drive high
range, neutral, and four wheel drive low range.
This transfer case is intended to be driven in the two
wheel drive (2H) position for normal street and highway
conditions such as dry hard surfaced roads.
In the events when additional traction is required, the
transfer case 4H and 4L positions can be used to lock the
front and rear driveshafts together and force the front
and rear wheels to rotate at the same speed. This is
accomplished by simply moving the shift lever to these
positions. The 4H and 4L positions are intended for loose,
slippery road surfaces only. Driving in the 4H and 4L
positions on dry hard surfaced roads may cause in-
creased tire wear and damage to the driveline compo-
nents. The 4WD indicator light, located in the instrument panel,
alerts the driver that the vehicle is in four wheel drive
and that the front and rear driveshafts are locked to-
gether. This light illuminates when the transfer case is
shifted to either the 4H or 4L positions.
NOTE:
Do not attempt to make a shift while only the
front or rear wheels are spinning. The transfer case is not
equipped with a synchronizer and therefore the front and
rear driveshafts 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 4L, the engine speed is
approximately three times that of the 2H or 4H positions
at a given road speed. Take care not to overspeed the
engine and do not exceed 25 mph (40 km/h).

slight application of the accelerator will supply maxi-
mum traction. When starting with only one rear wheel on
an excessively slippery surface, slight application of the
parking brake may be necessary to gain maximum trac-
tion.
WARNING!
On vehicles equipped with a limited-slip differen-
tial, never run the engine with one rear wheel off the
ground. The vehicle may drive through the rear
wheel remaining on the ground and cause you to
lose control of your vehicle.
AXLE LOCK (TRU–LOK™) — IF EQUIPPED
The Axle Lock switch is located on the lower center of the
instrument panel.
This feature will only activate when the following con-
ditions are met:
