Engine Coolant Temperature Gage
United States Canada
This gage shows the engine coolant temperature.To prevent engine overheating, the air conditioning
compressor will turn off automatically just prior to the
gage pointer entering the shaded 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 shaded 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.

This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn't come on, have it repaired.
This light will also come on during a malfunction in
one of two ways:

Light Flashing
-- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.

Light On Steady
-- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:

Reducing vehicle speed.

Avoiding hard accelerations.

Avoiding steep uphill grades.

If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.If the light stops flashing and remains on steady, see ªIf
the Light Is On Steadyº following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see ªIf the Light
Is On Steadyº following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See ªFilling Your Tankº in the Index. The
diagnostic system can determine if the fuel cap has been
left off or improperly installed. A loose or missing fuel
cap will allow fuel to evaporate into the atmosphere. A
few driving trips with the cap properly installed should
turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.

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 buttons.
(Defog): This setting directs most of the airflow to
the floor ducts and the 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.
(Floor): This setting directs most of the airflow to
the floor ducts with some airflow directed to the side
window defrosters. There is also a small amount of
airflow directed to the front defroster.
(Bi-Level): This setting directs airflow through
both the instrument panel outlets and the floor ducts.
There is also a small amount of air directed to the front
defroster and the side window defrosters.
(Vent): This setting directs airflow through the
instrument panel outlets.
FRONT (Defrost): This setting directs most of
the airflow to the windshield defroster with some
airflow to the side window defrosters and floor ducts.
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 (Recirculation): 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.

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 recirculation under these conditions and turn
the A/C on to help dehumidify the air.
A/C (Air Conditioning): 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 vent 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.

the floor ducts.

DEFOG: This setting directs most of the airflow to
the floor ducts and the windshield outlets.
BI
-LEVEL: This setting directs airflow through
both the instrument panel outlets and the floor ducts.
This mode will deliver slightly warmer air through
the floor ducts.

PANEL: This setting directs airflow through the
instrument panel outlets.
Whenever MODE is pressed, the display will show the
current system settings for five seconds before returning
the display to the exterior temperature.
FRONT (Defrost): This setting directs most
of the airflow to the windshield with some airflow to the
side window outlets and floor ducts.
To improve windshield clearing performance when you
select FRONT defrost, the air conditioning compressor
will run automatically when outside temperatures are
above approximately 40F (4C). 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.
OUTSIDE AIR: Press this button to send
outside air through the system.

3-6
RECIRC (Recirculation): 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 limit odors entering the vehicle.
RECIRC may be selected in all manual airflow modes
except FRONT defrost. If you select RECIRC while in
FRONT defrost, the RECIRC light will flash to let you
know that this is not allowed by the system. This is to
prevent fogging.
When the weather is cool or damp, operating the system
in recirculation, without also using the air conditioning,
may cause fogging of the windshield. To clear the fog,
switch back to outside air, select defog or FRONT
defrost mode and increase the fan speed. To avoid
refogging of the windows, minimize your use of
recirculation under these conditions and turn the air
conditioning on to help dehumidify the air.
A/C (Air Conditioning): Press this button to
turn the air conditioning compressor on and off. This
system will cool and dehumidify the air inside your
vehicle. The air conditioning compressor will also run
when you select the FRONT defrost mode and outside
temperatures are approximately 40
F (4
C) or
higher. When in AUTO mode, air conditioning will
automatically be used as needed to maintain the selected
temperature setting.AUTO (Automatic Control): Press the AUTO
button for automatic control of the air delivery mode,
fan speed, air conditioning and recirculation. Whenever
AUTO is pressed, the display will show the current
settings for five seconds before returning the display to
exterior temperature and AUTO.
The fan speed and mode of airflow delivery will vary as
the system maintains the selected temperature setting.
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 is hot
enough outside, the air inlet mode will automatically
switch to recirculation.
To find you comfort zone for the automatic settings,
start with a temperature setting of 75
F (24
C) and
allow about 20 minutes for the system to regulate.
Then turn the TEMP knobs 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.
