17. Temperature Gauge
If the pointer rises to theH(red) mark, the instrument
cluster will sound a chime. Pull over and stop the vehicle.
Idle the vehicle with the air conditioner turned off until
the pointer drops back into the normal range. If the
pointer remains on theH(red) mark, turn the engine off
immediately and call for service.
There are steps that you can take to slow down an
impending overheat condition. If your air conditioning is
on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to Floor and
the Fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.18. Cruise Indicator Light — If Equipped
This indicator shows that the Speed Control
System is ON.
19. Cruise SET Indicator Light — If Equipped
This indicator shows that the Speed Control System is
SET.
20. Transmission Range Indicator
This display indicator shows the automatic transmission
gear selection.
21. Odometer/Trip Odometer Reset Button
Press this button to change the display from odometer to
either of the two trip odometer settings. Trip A or Trip B
will appear when in the trip odometer mode. Push in and
hold the button for two seconds to reset the trip odometer
to 0 mi (0 km). The odometer must be in Trip mode to
reset.

CLIMATE CONTROLS
Climate Controls
The Climate Control System allows you to balance the
temperature, amount, and direction of air circulating
throughout the vehicle. The controls are located on the
instrument panel, below the radio.The air conditioning system of your vehicle contains
R-134a, a refrigerant that does not deplete the ozone layer
in the upper atmosphere.
The controls are as follows:
Mode Control (Air Direction)
The mode control allows you to
choose from several patterns of air
distribution. You can select either
a primary mode, as identified by
the symbols, or a blend of two of
these modes. The closer the con-
trol is to a particular mode, the
more air distribution you receive
from that mode.
Panel
Air is directed through the outlets in the instrument
panel. These outlets can be adjusted to direct air
flow.

Bi-Level
Air is directed through the panel and floor outlets.
NOTE:There is a difference in temperature between the
upper and lower outlets for added comfort. The warmer
air goes to the floor outlets. This feature gives improved
comfort during sunny but cool conditions.
Floor
Air is directed through the floor outlets and side
window demister outlets with a small amount
through the defrost outlet.
Mix
Air is directed through the floor, defrost and side
window demister outlets. This setting works best in
cold or snowy conditions that require extra heat at
the windshield. This setting is good for maintaining
comfort while reducing moisture on the windshield.Defrost
Air is directed through the windshield and side
window demister outlets. Use this mode with
maximum fan and temperature settings for best wind-
shield and side window defrosting.
NOTE:The air conditioning compressor operates in
both Mix and Defrost or a blend of these modes even if
the Air Conditioning Snowflake button is not pressed.
This dehumidifies the air to help dry the windshield. To
improve fuel economy, use these modes only when
necessary.
Air Outlets
The airflow from each of the instrument panel outlets can
be adjusted for direction and turned on or off to control
air flow.
228 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE:For maximum airflow to the rear seat passen-
gers, the center instrument panel outlets can be aimed, so
that the left center outlet is directed toward the right rear
passenger and the right center outlet is directed toward
the left rear passenger.
Fan Control
Use this control to regulate the
amount of air forced through the
system in any mode you select.
The fan speed increases as you
move the control from left (OFF)
to right.
Temperature Control
Use this control to regulate the
temperature of the air inside the
passenger compartment. The blue
area of the scale indicates cooler
temperatures while the red area
indicates warmer temperatures.
NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser: located in front of the radiator, for an accumula-
tion of dirt or insects. Clean with a gentle water spray
from behind the radiator and through the condenser.
Fabric front fascia protectors may reduce air flow to the
condenser, reducing air conditioning performance.

Circulation Control
Use this button to choose between
outside air intake or recirculation
of the air inside the vehicle. A
lamp will illuminate when you
are in recirculate mode. Only use
the recirculate mode to tempo-
rarily block out any outside odors,
smoke, or dust and to cool the
interior rapidly upon initial start
up in very hot or humid weather.
NOTE:Continuous use of the recirculate mode may
make the inside air stuffy and window fogging may
occur. Extended use of this mode is not recommended.
In cold or damp weather, the use of the Recirculate
position will cause windows to fog on the inside because
of moisture build up inside the vehicle. For maximum
defogging, select the Outside Air position.NOTE:Recirculation Mode will not operate in floor, mix
or defrost modes.
Air Conditioning
Normal
Use this button to engage the Air
Conditioning. A lamp will illumi-
nate when the Air Conditioning
System is engaged. Once the air
conditioning is engaged, use a
combination of the mode control,
fan speed control, and tempera-
ture control to achieve your de-
sired interior temperature.
NOTE:The air conditioning compressor will not engage
until the engine has been running for about 10 seconds.

Towing Tips — Automatic Transmission
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. Refer to the “Main-
tenance Schedule” in Section 8 for transmission fluid
change intervals.
NOTE:Check the automatic transmission fluid level
before towing.
Towing Tips — Electronic Speed Control (If
Equipped)

Don’t use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Towing Tips — Cooling System
To reduce the potential for engine and transmission
overheating, take the following actions:
City Driving
When stopped for short periods of time, put transmission
in NEUTRAL but do not increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
refer to Cooling System Operating information in the
Maintenance section of this manual for more informa-
tion.
328 STARTING AND OPERATING

HAZARD WARNING FLASHER
The flasher switch is located on the instrument
panel, below the radio. Depress the switch and
both cluster indicators and all front and rear
directional signals will flash. Depress the
switch again to turn Hazard Warning Flashers off.
Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is disabled
and is creating a safety hazard for other motorists.
If it is necessary to leave the vehicle to go for service, the
flasher system will continue to operate with the ignition
key removed and the vehicle locked.
NOTE:With extended use, the flasher may wear down
your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways — Slow down.
•In city traffic — While stopped, put the transmission in
NEUTRAL, but do not increase engine idle speed.
If the pointer rises to theH(red) mark, the instrument
cluster will sound a chime. When safe, pull over and stop
the vehicle with the engine at idle. Turn off the air
conditioning and wait until the pointer drops back into
the normal range. If the pointer remains on theH(red)
mark for more than a minute, turn the engine off imme-
diately and call for service.
NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
