To prevent engine overheating, the air conditioning
compressor will turn off automatically just prior to the
gage pointer entering the red area. As the engine cools
down, the air conditioning compressor will automatically
turn back on. On vehicles equipped with the DIC, the
message ENGINE HOT... A/C DISABLED will appear in
the DIC display and a warning chime will sound.
If the gage pointer moves into the red area, your engine
is too hot. On vehicles equipped with the systems
monitor, the CHECK GAGES light will come on and
a warning chime will sound.
On vehicles with a DIC, a CHECK GAGES
TEMPERATURE message will be displayed and a
warning chime will sound. See ªDIC Warnings and
Messagesº in the Index for more information.
The section ªProblems on the Road,º in this manual
explains what to do if your engine overheats.
See ªEngine Overheatingº in the Index.Tire Pressure Light (If Equipped)
The check tire pressure system can alert you to a large
change in the pressure of one tire. After the system has
been properly calibrated, the TIRE PRESS light will
come on if a pressure difference (low pressure) is
detected in one tire.
The light will stay on until you turn off the ignition or
reset (calibrate) the system. See ªCheck Tire Pressure
Systemº in the Index.
The TIRE PRESS light also comes on briefly when you
turn your ignition key to START. If the light doesn't
come on then, have it fixed so it will be there to tell you
if the pressure in a tire is low.
If the anti
-lock brake system warning light comes on, the
check tire pressure system may not be working properly.
See your dealer for service. Also, see ªAnti
-Lock Brake
System Warning Lightº in the Index.

Comfort Controls
This section tells you how to make your air system
work for you.
With these systems, you can control the heating,
cooling and ventilation in your vehicle. Your vehicle
also has a flow
-through ventilation system described
later in this section.
Your vehicle may be equipped with a passenger
compartment air filter. For more information, see
ªPassenger Compartment Air Filterº in the Index.
Comfort Controls Personalization
(If Equipped)
This feature allows two different drivers to store and
recall their own climate control settings for temperature,
air delivery mode and fan speed. The personal choice
settings recalled are determined by the transmitter used
to enter the vehicle. After the button with the unlock
symbol on a remote keyless entry transmitter is pressed,
and the ignition is in ON, the climate control will adjust
to the last settings of the identified driver. The settings
can also be changed by pressing one of the memory
buttons (1 or 2) located on the driver's door, until you
hear two beeps. When adjustments are made, the new
settings are automatically saved for that driver.
Standard Climate Control System
Fan Knob
The left knob regulates the force of the air coming
through the system. Turn the knob clockwise to increase
the fan speed and counterclockwise to decrease the fan
speed. Push this knob to turn the fan off. The fan must
be on to run the air conditioning compressor.
Temperature Knob
The right knob regulates the temperature of the air
coming through the system. Turn it toward the blue area
for cooler air. Turn it toward the red area for warmer air.

3-3
Mode Buttons
You may choose the direction of air delivery by
selecting one of the five mode control buttons.
PANEL: This setting directs airflow through the
upper air outlets located in the instrument panel.
BI-LEVEL: This setting directs airflow through
both the upper air outlets and the lower floor outlets.
There is also a small amount of air directed to the front
defroster and the side window defrosters.
FLOOR: This setting directs most of the airflow
to the lower floor outlets with some airflow directed to
the side window defrosters. There is also a small amount
of airflow directed to the front defroster.
DEFOG: This setting directs most of the airflow to
the lower floor outlets and the front windshield defroster.
A small amount of airflow is directed to the side window
defroster outlets. This mode can be useful to remove the
moisture from the inside of the windshield when the
outside temperature is cold or the humidity is high.
FRONT: This setting directs most of the airflow to
the front windshield defroster with some airflow to the
side window defrosters and lower floor outlets.
To improve windshield clearing performance when you
select FRONT defrost, your air conditioning compressor
will run automatically above approximately 40
F (4
C).
This dehumidifies the air to help dry the windshield. Even
though the compressor may be running, the A/C light will
not come on in FRONT defrost unless you select A/C.
Recirc Button
RECIRC: Press this button to limit the amount of
outside air entering your vehicle. This is helpful when
you are trying to quickly cool the interior of the vehicle
or to limit odors entering the vehicle. RECIRC may be
selected in all manual airflow modes except FRONT
defrost. If you select RECIRC while in defrost, the
RECIRC light will flash to let you know that this is
not allowed. This is to help prevent fogging.

3-4
When the weather is cool or damp, operating in
RECIRC for extended periods of time may cause
fogging of the vehicle's windows. To clear the fog,
switch back to outside air by turning off RECIRC, select
either DEFOG or FRONT defrost mode and increase the
fan speed. To avoid refogging of the windows, minimize
your use of RECIRC under these conditions and turn the
A/C on to help dehumidify the air.
A/C Button
A/C: Press this button to turn the air conditioning
compressor on and off. The system will cool and
dehumidify the air inside your vehicle. If your comfort
control system is off, you can also turn it back on in
PANEL mode by selecting the A/C button.
Even though A/C is not selected, in FRONT defrost
mode the A/C compressor will run automatically at
temperatures over approximately 40
F (4
C) to improve
windshield clearing performance.
Electronic Climate Control System (Option)
Temperature Knob (Driver's Side)
The driver's side knob changes the temperature of the
air coming through the system on the driver's side.
Turn the knob toward the blue area to decrease the set
temperature. Turn the knob toward the red area to
increase the set temperature. When this knob is adjusted,
the word DRIVER will be displayed under the set
temperature. When the passenger's set temperature is
not active, this knob controls both the driver's and
passenger's side, and both DRIVER and PASS will be
displayed under the set temperature.

3-6
Automatic Operation
When the system is set for AUTO, your climate control
system will control the air delivery mode, fan speed, A/C
and RECIRC operations. Air will come from the floor,
panel or windshield outlets. The fan speed will vary as the
system maintains the selected temperature setting.
When AUTO is selected, the A/C operation and air inlet
will be automatically controlled. The air conditioning
compressor will run at outside temperatures 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 zone, start with 75
F (24
C)
temperature setting and allow about 20 minutes for the
system to regulate. Turn the TEMP knob up or down to
adjust the temperature setting if necessary. If you choose
the temperature setting of 60
F (15
C), the system will
remain at the maximum cooling setting and fan speed. If
you choose the temperature setting of 90
F (33
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 temperature based on sun load.
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 previous temperature.
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. Pushing the fan button will override
this delay and change the fan to a selected speed.

3-7
Manual Operation
You may also manually adjust the air delivery mode
or fan speed.
FLOOR: Manually selecting FLOOR mode by
cycling through the MODE settings will deliver air to
the floor outlets.
DEFOG: Manually selecting DEFOG by cycling
through the MODE settings will deliver air to the floor
and windshield outlets.
BI-LEVEL: Manually selecting BI-LEVEL by
cycling through the MODE settings will deliver warm air
to the floor and cooler air to the instrument panel outlets.
PANEL: Manually selecting PANEL by cycling
through the MODE setting will deliver air to the
instrument panel outlets.
DRIVER PUSH OFF: Press this knob to turn the
system off. Some fresh air will continue to flow through
the vehicle from the FLOOR outlets, and the system will
try to maintain the previously chosen comfort setting.PASSENGER PUSH OFF: Press this knob to cancel
the passenger's set temperature. The passenger's set
temperature will be set equal to the driver's set
temperature. Both the words DRIVER and PASS will be
displayed under the set temperature in the display area.
A/C: Press this button to turn the air conditioning
compressor on and off. When A/C is selected or in
AUTO mode, the system will run the A/C automatically
to cool and dehumidify the air inside 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.
RECIRC: Press this button to limit the amount of
outside air entering your vehicle. You may use this setting
to limit odors entering your vehicle. Press RECIRC to
recirculate inside air until the RECIRC button is pressed
again or the OUTSIDE AIR button is pressed.
If you select RECIRC while in defrost the RECIRC light
will flash to let you know this is not allowed. This is to
prevent fogging.

3-8
When the weather is cool or damp, operating in
RECIRC for extended periods of time may cause
fogging of the vehicle's windows. To clear the fog, press
the OUTSIDE AIR button and 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.
OUTSIDE AIR: Press this button to allow fresh
air to enter your vehicle if you currently have RECIRC
selected. You may also override the system's automatic
use of RECIRC by selecting OUTSIDE AIR.
FRONT: Press this button to clear the windshield.
The system will automatically control the fan speed if
you select defrost from AUTO. If the outside
temperature is 38
F (3
C) or warmer, your air
conditioning compressor will automatically run to help
dehumidify the air and dry the windshield.
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.
If you have the standard system, for quick cool
-down on
very hot days, use the airflow from the PANEL outlets,
press RECIRC and A/C with the temperature knob in the
blue area. If this max A/C setting is used for long periods
of time, the air in your vehicle may become too cold and
dry. For normal cooling on hot days, use A/C without
RECIRC with the temperature knob in the blue area.
If you have the electronic system, in AUTO mode the
system will cool and dehumidify the air inside the vehicle.
Also while in AUTO mode, the system will maximize its
performance by using RECIRC as necessary.
On cool, but sunny days, with the standard system or
through manual operation of the electronic system, use
BI
-LEVEL to deliver warm air to the floor and cooler
air to the instrument panel outlets. To warm or cool the
air delivered, turn the TEMP knob up or down.
