The light also will turn on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
21. Malfunction Indicator Light (MIL) The Malfunction Indicator Light (MIL) is part of
an Onboard Diagnostic system (OBD II) that
monitors the emissions and engine control sys-
tem. 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 5 seconds, and
remain on until the vehicle is started. If the bulb does not
come on during starting, have the condition 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 an authorized 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 drivability. If the MIL is
flashing, severe catalytic converter damage and
power loss will soon occur. Immediate service is
required.

23. Airbag Warning LightThe airbag warning light will illuminate and
remain lit for six to eight seconds when the
ignition is first turned ON. If the light does not
illuminate 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. Refer to
“Occupant Restraints” in “Things To Know Before Start-
ing Your Vehicle” for further information.
24. 4WD Indicator This light indicates the vehicle is in four-wheel
drive and 4LOCK. 4WD allows all four wheels
to receive torque from the engine simulta-
neously.
25. SVC (Service) 4WD Indicator
The SVC 4WD illuminates when the ignition key is
turned to the ON position and will stay on for two seconds. If the light stays on or illuminates during
driving, it means that the 4WD system is not functioning
properly and that service is required.
26. Cruise Indicator
The cruise indicator illuminates when the electronic
speed control system is turned on.
27. Cargo Lamp
The Cargo Lamp indicator will illuminate
when the Cargo Lamp is activated by pressing
the CARGO button, located on the headlight
switch.
28. TOW/HAUL
The TOW/HAUL button is located at the end of the gear
shift lever. This light will illuminate when the TOW/
HAUL button has been selected.

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
either through the panel outlets or
both the panel and floor outlets to-
gether, depending on 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.Mode Control

Temperature Control
The rotary knob at the center of the
control panel controls the temperature
of the interior air. You can choose your
degree of comfort by rotating the
knob. The coldest temperature setting
is to the extreme 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 airflow 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
240 UNDERSTANDING YOUR INSTRUMENT 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 cool
temperatures when it’s rainy or humid. In most cases
turning on the Air-conditioning (pressing the SNOW-
FLAKE 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 blowerspeeds 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. Refer to “Cooling System” under “Main-
tenance Procedures” in “Maintaining Your Vehicle”.

When using the air conditioner in extremely heavy
traffic, in hot weather, especially when towing a trailer,
additional engine cooling may be required. If this situa-
tion is encountered, operate the transmission in a lower
gear and set the air conditioner to recirculation mode.
Operating the air conditioner in recirculation mode pro-
vides the maximum performance from your air condi-
tioning. When stopped in heavy traffic, it may be neces-
sary to shift into NEUTRAL and press 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.
