Comfort Controls
Air Conditioning with Electronic Controls
With this system, you can control the heating, cooling
and ventilation in your vehicle. The system works best if
you keep your windows closed while using it.Fan Knob
The left knob selects the force of air you want. To turn
the fan off, turn the knob to OFF. The fan must be on to
run the air conditioning compressor.
If the airflow seems very low when the fan knob is turned
to the highest setting, regardless of the mode setting, your
passenger compartment air filter (if equipped) may need to
be replaced. See ªMaintenance Scheduleº and ªPassenger
Compartment Air Filterº in the Index.
Temperature Knob
The right knob changes the temperature of the air
coming through the system. Turn this knob clockwise
(toward red) for warmer air. Turn it counterclockwise
(toward blue) for cooler air.
Mode Push Buttons
The upper row of push buttons control the direction of
airflow. Each button has an indicator which will glow
when the button is pressed.
UPPER: This setting directs air through the
instrument panel outlets.

3-7 Manual Control of the Automatic System
If you prefer to manually control the heating, cooling
and ventilation in your vehicle, set the system to the
temperature and fan speed you want. Next, push the mode
button to select your desired airflow direction. The system
will try to maintain the temperature you set using the
mode you select. The following suggestions will help the
system run more efficiently in manual mode.
Fan Button
: The button below the display is used to manually
select the force of air you want. The display will show
the fan speed. Fan control is no longer automatic, but
the system remains in auto temperature control.
If the airflow seems very low when the fan knob is
turned to the highest setting regardless of the mode
setting, your passenger compartment air filter (if
equipped) may need to be replaced. See ªMaintenance
Scheduleº in the Index.
A/C Button
Press the A/C button to turn the compressor on and off.
AUTO will then be extinguished, but system will
maintain auto air delivery and auto blower.Econ Button
If your vehicle is equipped
with this button, you can
turn the compressor on
and off.
Press the ECON button to turn the compressor on
and off. The indicator light is illuminated when the
compressor is off. AUTO will be not be illuminated, but
the system will maintain automatic air delivery and
blower control. The system will attempt to control the
temperature without the help of the compressor.

4-40 When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you're
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don't overfill),
engine oil, drive belts, cooling system and brake system.
Each of these is covered in this manual, and the Index
will help you find them quickly. If you're trailering, it's
a good idea to review this information before you
start your trip.
Check periodically to see that all hitch nuts and
bolts are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See ªEngine Overheatingº
in the Index.

5. Hold the air box cover and air duct assembly up in
position while removing the air filter element from
the air box.
6. To install the air cleaner/filter, reverse the steps.Be sure the tabs on the cover are inserted into the
air box slots.
Refer to the Maintenance Schedule to determine when to
replace the air filter.
See ªScheduled Maintenance Servicesº in the Index.

6-19
CAUTION:
Operating the engine with the air cleaner/filter
off can cause you or others to be burned. The air
cleaner not only cleans the air, it stops flame if
the engine backfires. If it isn't there, and the
engine backfires, you could be burned. Don't
drive with it off, and be careful working on the
engine with the air cleaner/filter off.
NOTICE:
If the air cleaner/filter is off, a backfire can cause
a damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner/filter in place when
you're driving.
Passenger Compartment Air Filter
(If Equipped)
The passenger compartment air filter is located
underneath the hood just below the windshield wiper
arm on the passenger's side of the vehicle (underneath
the air inlet grille).
The filter traps most of the pollen from air entering the
module. Like your engine's air cleaner/filter, it may
need to be changed periodically. For information on how
often to change the passenger compartment air filter, see
ªMaintenance Scheduleº in the Index.

6-20
To change the passenger compartment air filter, use the
following steps:
1. Turn off the ignition when the windshield wipers are
in the up position.
2. Raise the hood.
3. Disconnect the windshield washer pump hose from
the fender rail and air inlet grille.
4. Reposition the hood weatherstrip from the right side
of the vehicle (peel back halfway to center).
5. Remove the air inlet grille retainers.
6. Remove the air inlet grille.
7. Remove the air deflector grille in the compartment.
8. Remove the passenger compartment air filter.
9. Then reverse the steps to install the new air filter.Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches 90F (32C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of
these conditions, change the fluid and filter at
100,000 miles (166 000 km).
See ªScheduled Maintenance Servicesº in the Index.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at the dealership service department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading on the dipstick.

2. Push it back in all the way, wait three seconds and
then pull it back out again.
3. Check both sides of the dipstick, and read the
lower level. The fluid level must be in the
cross
-hatched area.
4. If the fluid level is in the acceptable range, push the
dipstick back in all the way.
How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use. See ªRecommended
Fluids and Lubricantsº in the Index.If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross
-hatched area
on the dipstick.
1. Pull out the dipstick.
2. Using a long
-neck funnel, add enough fluid at the
dipstick hole to bring it to the proper level.
It doesn't take much fluid, generally less than
one pint (0.5 L). Don't overfill.
NOTICE:
We recommend you use only fluid labeled
DEXRON-III, because fluid with that label is
made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON
-III
is not covered by your new vehicle warranty.
3. After adding fluid, recheck the fluid level as
described under ªHow to Check.º
4. When the correct fluid level is obtained, push the
dipstick back in all the way.
