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 ªclearº 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, ventilation and air condi-
tioning system in this vehicle consist of a series of rotary
knobs. These comfort controls can be set to obtain desired
interior conditions.
Air Conditioning And Heater
Air Conditioning And Heater Operation
To turn on the Air Conditioning, set the fan control at any
speed and press the snowflake button located at the right
of the control panel. Conditioned air will be directed
through the outlets selected by the mode control. A light

at the top of the snowflake button shows that the air
conditioning is on. Press the button a second time to turn
the air conditioning off.
Slight changes in engine speed or power may be noticed
when the air conditioning compressor is on. This is a
normal occurrence as the compressor will cycle on and
off to maintain comfort and increase fuel economy.
The mode control (at the right of the
control panel) can be set in any of the
following positions:
NOTE:To improve your selection choices, the system
allows you to operate at intermediate positions between
the major modes. These intermediate positions are iden-
tified by the small dots.Recirculation Modes (Panel or Bi-Level )
Select the recirculation modes when
the outside air contains dust, odors,
high humidity, or if rapid cooling is
desired. This feature allows for recir-
culation of interior air only. Air flows
through either the panel outlets or
both the panel and floor outlets, to-
gether, depending which recirculation mode is selected.
Panel (Fresh Air Modes)
Outside air flows through the outlets located in the
instrument panel.
Bi-Level
Outside air flows through the outlets located in the
instrument panel and at the floor.
Floor
Outside air flows primarily through the floor out-
lets located under the instrument panel.
Mode Control

Mix
Outside air flows in equal proportions through the
floor and defroster outlets.
Defrost
Outside air is primarily directed to the windshield
through the defroster outlets located at the base of
the windshield, and the demister outlets located at the
edge of each side of the instrument panel.
NOTE:The air conditioner compressor operates in both
Mix and Defrost or a blend of these modes, even if the
A/C button has not been pressed. This dehumidifies the
air to help dry the windshield.
Blower Control
The rotary knob on the left of
the control panel is the
blower control. Turn the knob
clockwise to one of the four
positions to obtain the blower
speed you desire. To turn the
blower off, turn the knob to
the far left position.

Temperature Control
The rotary knob at the center
of the control panel controls
the temperature of the inte-
rior air. You can choose your
degree of comfort by rotating
the knob. The coldest tem-
perature setting is to the ex-
treme left (blue region) and
the warmest setting is to the
extreme right (red region) of
the rotation.
Circulation
The cab is designed with features to promote outside air
circulation. There are grilles in the cab back panel. These
are air exhausters that provide the means for regular
exchange of cab air.Side window demisters direct air flow specifically to the
window glass to help prevent interior fogging of the
glass. They are located in the extreme outside upper
edges of the instrument panel. The demisters also pro-
vide extra air ducts for circulation. They are in operation
whenever the Floor, Mix, Defrost, or Bi-Level modes are
in use.
NOTE:When you turn off the engine you may hear a
hissing sound from under the hood for a short period of
time. This is a normal condition that occurs if the air
conditioning system has been on. It is not an indication of
a problem with the air conditioning system.

Operating Tips
Fast Cooldown
For a fast cooldown, open the windows and turn the
blower fan rotary knob to the extreme right position, turn
the mode control to the panel fresh position, press the
snowflake button to turn on the air conditioning, and
drive with the windows open for the first few minutes.
Once the hot air has been expelled, close the windows
and turn the mode selector to the Recirculation Panel
Mode or Recirculation Mode Bi-level position. When a
comfortable condition has been reached, choose a mode
position and adjust the temperature control knob and
blower speed as necessary to maintain comfort. For high
humidity conditions it may be necessary to remain in the
Recirculation mode to maintain comfort.
Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cooltemperatures when it's rainy or humid. In most cases
turning on the Air-conditioning (pressing the snowflake
button) will clear the fog. Adjust the temperature control,
air direction and blower speed to maintain comfort.
As the temperature gets colder it may be necessary to
direct air onto the windshield by using MIX Mode
position on the control. Adjust the temperature control
and blower speed to maintain comfort. High blower
speeds will reduce fogging. Interior fogging on the
windshield can be quickly removed by selecting the
defrost mode.
Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates on the inside of windows can increase the
rate of window fogging.

Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50%
concentration of engine coolant to distilled water is
recommended. See ªCooling Systemº in the Maintaining
Your Vehicle section of your Owner's Manual.
When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gearand set the air conditioner to recirculation mode. Oper-
ating the air conditioner in recirculation mode provides
the maximum performance from your air conditioning.
When stopped in heavy traffic, it may be necessary to
shift into NEUTRAL and depress the accelerator slightly
for fast idle operation.
Winter Operation
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 obstruc-
tions. This will help prevent snow going into the ducts.
