Automatic Operation
Press the AUTO button to set the system to automatically
control the air delivery mode, fan speed, air temperature
and recirculation operations. Whenever you press
AUTO, the display will change to show the current
driver's set temperature, automatic air delivery mode
and fan speed. Press the AUTO button again within
five seconds and the display will show the passenger's
set temperature. After five seconds the display will
change to the EXT (external) temperature outside
the vehicle.
When AUTO is selected, the air conditioning operation
and air inlet will be automatically controlled. The air
conditioning compressor will run when outside
temperature is over approximately 40
F (4
C).
The air inlet will normally be set to outside air. If it's
hot outside, the air inlet will automatically switch to
recirculated inside air to help quickly cool down
your vehicle.
To find your comfort setting, start with a 74
F (23
C)
temperature setting and allow about 20 minutes for the
system to regulate. Turn the driver's or passenger's
side temperature knob clockwise or counterclockwise
to adjust the temperature setting as necessary. If you
choose the temperature setting of 60
F (15
C),
the system will remain at the maximum cooling settingand fan speed. If you choose the temperature setting
of 90
F (32
C), the system will remain at the
maximum heat setting and fan speed. Choosing either
maximum setting will not cause the system to heat or
cool any faster.
Be careful not to cover the sensor located on the top of
the instrument panel near the windshield. This sensor
regulates air temperature based on sun load, and also
turns on your headlamps.
The EXT (exterior) temperature sensor is located in the
front of the vehicle behind the grille. The displayed
temperature is most accurate after the vehicle has been
moving for a few minutes. If the vehicle is stopped and
then restarted within 2 1/2 hours, the sensor will be hot
from the engine heat. In this case, the temperature first
displayed will continue to be the temperature that was
displayed before the vehicle was turned off. The display
will update after the vehicle has been moving for a few
minutes and the sensor has a chance to cool down to
the actual temperature.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on engine coolant
temperature. Pressing the fan switch will override
this delay and change the fan to a selected speed.

Manual Operation
You may manually adjust the air delivery mode or
fan speed. Use the mode button to cycle through the
following four air delivery modes:
(Panel): This setting will deliver air to the
instrument panel outlets.
(Bi-Level): This setting will deliver warmer air to
the floor and cooler air to the instrument panel outlets.
(Floor): This setting will deliver air to the
floor outlets.
(Defog): This setting will deliver air to the
floor and windshield outlets.
OFF: Press this button to turn the system off. Some
fresh air will continue to flow through the vehicle from
the floor outlets. The system will try to maintain the
previously chosen temperature setting.
(Recirculation): Press this button to limit
the amount of outside air entering your vehicle. This is
helpful when you are trying to limit odors entering your
vehicle and for maximum air conditioning performance
in hot weather. Press this button again to allow outside
air to enter the vehicleIf you select recirculation while in defrost, defog or
floor, the light on the button will flash and go out to let
you know this is not allowed. This is to prevent fogging.
When the weather is cool or damp, operating the system
in recirculation for extended periods of time may cause
fogging of the vehicle's windows. To clear the fog,
select either defog or FRONT defrost. Be sure A/C OFF
is not selected to allow the air conditioning compressor
to run automatically and help dehumidify the air.
(Air Conditioning): Press this button to turn
the air conditioning compressor on and off. When air
conditioning is selected or in AUTO mode, the system
will run the air conditioning automatically to cool and
dehumidify the air entering the vehicle. If you select
A/C OFF while in FRONT defrost, the A/C OFF text
will flash to let you know this is not allowed. This is to
prevent fogging.
FRONT (Defrost): Press this button to defrost
the windshield. The system will automatically control
the fan speed if you select defrost from AUTO.
If the outside temperature is 40
F (4
C) or warmer,
your air conditioning compressor will automatically
run to help dehumidify the air and dry the windshield.

3-6 Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
By pressing the AUTO button the system will cool and
dehumidify the air inside the vehicle. Also while in this
mode, the system will maximize its performance by
using recirculation as necessary.
On cool, but sunny days use the bi
-level mode to deliver
warmer air to the floor and cooler air to the instrument
panel outlets. To warm or cool the air delivered, turn the
temperature control to the desired setting.
Heating
Press AUTO and adjust the temperature by turning
the temperature knob clockwise or counterclockwise.
You may also adjust the automatic system manually
by pressing the MODE button and selecting floor.
Again, adjust the temperature by turning the
temperature knob clockwise or counterclockwise.Outside air will be heated and sent through the floor
outlets. The heater works best if you keep the windows
closed while using it.
Defogging and Defrosting
On cool, humid days, use defog to keep the windshield
and side windows clear. Use the FRONT defrost button
to remove fog or ice from the windshield quickly in
extremely humid or cold conditions.
If you select FRONT defrost or defog from AUTO,
the system will control the fan speed. Adjust the
temperature and fan speed to your comfort level.
After the windshield is clear, adjust the temperature
to your normal setting and press the AUTO button to
return to AUTO mode and fan control.
For maximum front defrost performance under
extreme icing or frosting conditions, increase the
temperature setting to 90
F (32
C) and increase
the fan speed to high.

7-21 Engine Cooling System Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed. Clean the
outside of the radiator and air conditioning condenser.
To help ensure proper operation, a pressure test of the
cooling system and pressure cap is recommended at
least once a year.
Transfer Case and Front Axle
(All-Wheel Drive) Inspection
Every 12 months or at engine oil change intervals,
check front axle and transfer case and add lubricant
when necessary. A fluid loss could indicate a problem;
check and have it repaired, if needed. Check vent hose
at transfer case for kinks and proper installation.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook
-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and
rotors for surface condition. Inspect other brake parts,
including calipers, parking brake, etc. Check parking
brake adjustment. You may need to have your brakes
inspected more often if your driving habits or conditions
result in frequent braking.
