Comfort Controls
This section tells you how to make your air system work
for you.
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 selects the force of air you want. Turn the
knob clockwise to increase fan speed or counterclockwise
to decrease fan speed. To turn the fan off (which will also
turn the climate control system off), turn the knob all the
way counterclockwise. In any other setting, the fan will
run continuously with the ignition on. The fan must be
on to run the air conditioning compressor.
Temperature Knob
The center knob controls the temperature of the air
coming through the system. Turn it counterclockwise
toward the blue area for cooler air. Turn it clockwise
toward the red area for warmer air.
Mode Knob
The right knob selects the location of where the air will
enter the vehicle. The available modes are the following:
(Vent): In this position most of the air comes
through the instrument panel outlets. A small amount of
air comes through the floor outlets.

3-3
(Bi-Level): In this position the air comes
through the instrument panel outlets and through
the floor outlets.
(Floor): In this position most of the air comes
through the floor outlets. The rest of the air comes
through the windshield and side window outlets.
(Defog): This position divides the air between
the floor outlets and the windshield defroster outlet.
The air conditioning compressor will run automatically
in this position when it is needed to help dry the air in
the vehicle.
(Defrost): This position directs most of the
air through the windshield defroster outlet. Some of
the air goes to the floor outlets. The air conditioning
compressor will run automatically in this position when
it is needed to help dry the air in the vehicle.
Mode Buttons
A/C (Air Conditioning): Press A/C to operate the
air conditioner compressor. The indicator light will glow
when the button is pressed to indicate that the air
conditioning system is operating.
(Outside Air): Press this button to allow the
circulation of outside air in the vehicle. The indicator
light on the button will glow when pressed. Outside air
is available in all modes including OFF. Outside air is the
default setting and is automatically activated in defog and
defrost or when turning the climate control system on or
turning the ignition switch from OFF to ON.
Pressing this button will cancel recirculation.
(Recirculation): Press this button to limit the
amount of outside air entering your vehicle. This is also
helpful when you are trying to limit odors entering your
vehicle. The indicator light on the button will glow
when it is pressed. Recirculation is available in all
modes, except defog and defrost.
Pressing this button will cancel outside air.
It is not recommended to use recirculation in the floor
mode with heat. It is useful to quickly cool the vehicle
on hot days.

3-4 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, after the vehicle has
started to cool down, use the vent mode with the
temperature knob in the blue area and the A/C button
pressed. 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.
For quicker cool
-down on very hot days, use the vent
mode with the temperature knob all the way in the blue
area and the A/C button pressed. Begin with the outside
air button pressed for a few minutes, or until the vehicle
begins to feel cool. Then press the recirculation button. If
the recirculation setting is used for long periods of time,
the air in your vehicle may become too dry.
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 button pressed. The system will
bring in outside air and direct slightly warmer air to
your lower body.
Heating
On cold days, use floor mode and outside air 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 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 in your engine and heating
system that is used to provide heat. See ªEngine Coolant
Heaterº in the Index.

3-5 Defogging and Defrosting Windows
Your system has two settings 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 defrost and adjust the
fan to the highest speed. To warm passengers while
keeping the front window clean, use defog.
When you switch to defog or defrost modes your system
will automatically move from recirculation into outside
air. When you move the mode knob back into vent or
bi
-level modes, the system will move back into
recirculation. When the vehicle is turned off and back
on, the system will default to outside air automatically.
If you select recirculation while in vent, bi
-level or
floor modes, humid air can recirculate inside the vehicle
and allow moisture to form on the windows. If this
happens, select either the defog or defrost mode.
Recirculation mode in cold weather should be used only
for outside odor control so that fog formation on the
windows is reduced.Your vehicle is equipped with side window defogger
vents. The side window defogger outlets 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. For additional airflow to the
side windows, aim the side outlets toward the windows
and close the center outlets.
Recirculation will not operate in defog or defrost. This
is done to prevent recirculation of humid inside air and
allow the system to work properly. The system will
automatically default to outside air when defog or
defrost modes are selected.

3-6 Rear Window Defogger
The rear window defogger
button is located on the
lower right corner of the
control panel.
The rear window defogger uses a warming grid to
remove fog from the rear window.
Press the defogger button to turn the system on. The
indicator light will glow. The rear window defogger will
turn itself off after about 10 minutes the first time the
button is pressed, and 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.
The rear window defogger is designed to clear the center
of the window first.
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 vent mode to direct outside air
through your vehicle. Your vehicle also has the
flow
-through ventilation system.
Your vehicle's flow
-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
fan is running.

4-40 Driving On Grades
NOTICE:
Do not tow on steep continuous grades exceeding
6 miles (9.6 km). Extended, higher than normal
engine and transaxle temperatures may result
and damage your vehicle. Frequent stops are
very important to allow the engine and transaxle
to cool.
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don't shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around 45 mph (70 km/h) to reduce the
possibility of engine and transaxle overheating.
Pay attention to the engine coolant gage. If the indicator
is in the red area, turn off the air conditioning to reduce
engine load. See ªEngine Overheatingº in the Index.
Parking on Hills
CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People can
be injured, and both your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on a hill, here's
how to do it:
1. Apply your regular brakes, but don't shift into
PARK (P) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking
brake and shift into PARK (P).
5. Release the regular brakes.

7-32 Fuel System Inspection
Inspect the complete fuel system for damage or leaks.
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
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.
