Comfort Controls
With this system, you can control the ventilation
and heating in your vehicle. Your vehicle also has
the flow
-through ventilation system described later
in this section.
Climate Control System with
Air Conditioning
Fan Knob
The left knob regulates the fan speed. To select the force
of air you want, turn the knob. The fan is always
running unless the fan knob is moved to OFF.Temperature Knob
The center knob regulates the temperature of the air
coming through the system.
Mode Knob
The right knob changes the functions of your system.
MAX (Maximum): Use this mode for
maximum cooling. This setting recirculates much of
the air inside your vehicle. It maximizes your air
conditioner's performance and your vehicle's fuel
economy. The air conditioning compressor will run
automatically in this position when it is needed to
help dry the air in the vehicle.
(Vent): In this mode most of the airflow comes
through the instrument panel outlets. A small amount of
air comes through the floor vents. Set the center knob to
the desired temperature for comfort.
(Bi-Level): In this position the airflow
comes through the instrument panel outlets and
through the floor outlets. Set the center knob to the
desired temperature.

3-3
(Floor): In this mode most of the airflow comes
through the floor outlets. The rest of the air comes
through the windshield and side window vents. Set the
center knob to the desired temperature for comfort.
(Defog): This mode divides the airflow between
the floor outlets and the windshield defroster vent. The
air conditioning compressor will run automatically in
this mode when it is needed to help dry the air in
the vehicle.
(Front Defroster): This mode directs most of the
airflow through the windshield defroster vent. Some of
the air goes to the floor outlets. The air conditioning
compressor will run automatically in this mode when it
is needed to help dry the air in the vehicle.
Mode Button
A/C (Air Conditioning): Press A/C to operate the
air conditioning. The indicator light above the button
will glow when the button is pressed to indicate that the
air conditioning system has been turned on. The fan
knob must be set to a speed for the air conditioning
to operate.
Air Conditioning
The air conditioner and heater work best if you keep
your windows closed while using them. Your vehicle
also has the flow
-through ventilation system described
later in this section.
For normal cooling on hot days, use the vent mode with
the temperature knob in the blue area and the A/C
indicator light glowing. The system will bring in outside
air and cool it.
On very hot days, begin by opening the windows long
enough to let hot inside air escape. This reduces the time
it takes for your vehicle to cool down, which should
help fuel economy.
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 mode with the temperature knob in
the middle and the A/C indicator light glowing. The
system will bring in outside air and direct slightly
warmer air to your lower body.

3-4 Heating
On cold days, use floor mode 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 outlets.
Your vehicle has heat ducts that are directed toward
the rear seat. Keep the area under the front seats
clear of objects 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 in your engine and heating
system that is used to provide heat. See ªEngine Coolant
Heaterº in the Index.
Defogging and Defrosting Windows
Your system has two modes for clearing the front and
side windows. For each setting, adjust the temperature
control as desired.
To defrost the front window quickly, turn the
temperature knob all the way in the red area. Use front
defroster and adjust the fan to the highest speed. To
warm passengers while keeping the front window clean,
use defog.
Your vehicle is equipped with side window defogger
vents. The side window defogger vents are located on
the outside of the side instrument panel vents. To defrost
the side windows, turn the temperature knob all the way
in the red area. Use floor mode and adjust the fan to the
highest speed.
To defog the side windows while using air conditioning,
use bi
-level mode and adjust the fan to the highest speed
and press the A/C button so that the indicator light is
glowing. For added airflow to the side windows, aim
the side vents toward the windows and close the
center vents.

3-5 Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The button is located
near the center of the
instrument panel.
Press the defogger button. The indicator light above the
button will glow. The rear window defogger will turn
itself off after about 10 minutes after the first time the
button is pressed, and after five minutes each additional
time the button is pressed. You can turn the defogger off
by pressing the button again or turning off the ignition.
Do not attach a temporary vehicle license across the
defogger grid on the rear window.
NOTICE:
Don't use a razor blade or anything else sharp on
the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn't be covered by your warranty.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use the vent mode to direct outside
air through your vehicle. Your vehicle also has the
flow
-through ventilation system which supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
is running. Recirculation of the air is automatic in
MAX A/C.

7-20 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.
Throttle System Inspection
Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts as
needed. Replace any components that have high effort
or excessive wear. Do not lubricate accelerator and
cruise control cables.
Brake System Inspection
(Except GT Series)
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. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including
drums, wheel cylinders, calipers, parking brake, etc.
The parking brake is self
-adjusting and no manual
adjustment is required. You may need to have your
brakes inspected more often if your driving habits or
conditions result in frequent braking.
Brake System Inspection (GT Series Only)
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. You may need to
have your brakes inspected more often if your driving
habits or conditions result in frequent braking.
