Comfort Controls
This section tells you how to make your air system work
for you. With these systems, you can control the
ventilation and heating in your vehicle. Your vehicle
also has the flow
-through ventilation system described
later in this section.
Standard Climate Control System
Fan Knob
The left knob selects the force of air you want.
Turn the knob clockwise to increase fan speed and
counterclockwise to decrease fan speed. To turn the fan
off, turn the mode knob all the way counterclockwise to
off. In any other setting, the fan will run continuously.
Temperature Knob
The center knob changes the temperature of the air
coming through the system. Turn this knob toward red
(clockwise) for warmer air. Turn it toward blue
(counterclockwise) for cooler air.
Mode Knob
The right knob has several settings to control the
direction of airflow. For each setting, select the
temperature that is comfortable.
VENT: This setting brings in outside air and directs
it through the instrument panel outlets.

Temperature Knob
The center knob changes the temperature of the air
coming through the system. Turn this knob toward red
(clockwise) for warmer air. Turn it toward blue
(counterclockwise) for cooler air.
Mode Knob
The right knob has several settings to control the
direction of airflow. For each setting, select the
temperature that is comfortable.
MAX: For maximum cooling use this setting to
recirculate much of the air inside your vehicle and send
it through the instrument panel outlets. The air
conditioning compressor will run automatically in this
setting when it is needed to help cool the air in the
vehicle. Operation in this mode during periods of high
humidity and cool outside temperatures may result in
increased window fogging. If window fogging is
experienced, select the defrost mode.
VENT: This setting brings in outside air and
directs it through the instrument panel outlets.
BI-LEVEL: This setting brings in outside air and
directs it two ways. Some air is directed through the
instrument panel outlets. Most of the air is directed
through the floor ducts and a little to the defrost and side
window vents.
FLOOR: This setting sends most of the air
through the ducts near the floor. The rest comes out of
the defroster and side window vents.
DEFOG: This setting allows half of the air to go
to the floor ducts and half to the defroster and side
window vents.
DEFROST: This setting directs most of the air
through the defroster and side window vents. Some of
the air goes to the floor ducts. The air conditioning
compressor will run automatically in this setting when it
is needed to help dry the air in the vehicle. The indicator
light will also be on in the setting.
Air Conditioning Compressor Button
Press the A/C button to operate the air conditioner
compressor. The indicator light above the button will
glow when the air conditioning compressor is running.
You don't have to press the button to run the compressor
in max or defrost.

3-5
It is normal for the A/C indicator light to come on while
in DEFROST.
Running the compressor will help reduce vehicle
interior fogging.
Air Conditioning (If Equipped)
On very hot days, open the windows long enough to
let hot, inside air escape. This reduces the time it takes
for your vehicle to cook down, which should help
fuel economy.
For quick cool down on very hot days, use max with the
temperature knob all the way in the blue area. If this
setting is used for long periods of time, the air in your
vehicle may become too dry. The best cool down
happens if you start in one of the other modes and then
switch to max.
For normal cooling on hot days, use vent with the
temperature knob in the blue area and the A/C button
pushed in. The system will bring in outside air and cool it.
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use bi
-level with the temperature knob in the
middle and the A/C button pushed in. The system will
bring in outside air and direct slightly warmer air to
your lower body. You may notice this temperature
difference more at some times than others.
Heating
On cold days, use floor with the temperature knob all
the way in the red area. The system will bring in outside
air, heat it and send it to the floor ducts.
Your vehicle has heat ducts that are directed toward
the rear seat. Keep the area under the front seats clear
of obstructions so the heated air can reach the rear
seat passengers.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (
-18
C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See ªEngine Coolant
Heaterº in the Index.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows. To defrost the windows quickly, use
DEFROST with the temperature knob all the way in
the red area. To warm passengers while keeping the
windows clean, use DEFOG.
