2-13 Resynchronization
After you have changed the battery in your remote
keyless entry transmitter, you will need to resynchronize
the transmitter. To do this, press the LOCK and
UNLOCK buttons together and hold for approximately
seven seconds (or until the horn chirps three times). You
will need to use this procedure if your vehicle has lost
battery power for an extended period of time.
Trunk Lid
CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even death.
CAUTION: (Continued)
CAUTION: (Continued)
If you must drive with the trunk lid open or if
electrical wiring or other cable connections must
pass through the seal between the body and
the trunk:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on VENT. That will force outside air into
your vehicle. See ªComfort Controlsº in
the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
Trunk Lock
To unlock the trunk from the outside, insert the key and
turn it clockwise.
You can also use the remote keyless entry transmitter, if
your vehicle is equipped.

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 Filter º 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. For each setting, set the temperature to a
comfortable setting. Each button has an indicator which
will glow when the button is pressed.
UPPER: This setting directs air through the
instrument panel outlets.
BI-LEVEL: This setting directs air two ways. Half
of the air is directed through the instrument panel outlets.
Most of the remaining 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 defrost and side
window vents. The air conditioning compressor will run

automatically in this setting unless the outside
temperature is below 40F (4.5C). (Even when the
compressor is running, you can control the temperature.)
DEFROST: This setting directs most of the air
through the defrost and side window vents. Some of the air
goes to the floor ducts. The air conditioning compressor will
run automatically in this setting unless the outside
temperature is below 40F (4.5C). (Even when the
compressor is running, you can control the temperature.)
Air Conditioning Compressor Button
Press the A/C button to operate the air conditioning
compressor. The indicator light on the button will flash
briefly and stay on solid to let you know your air conditioning
will come on. If the light on the A/C button turns off after
flashing has stopped your air conditioning will not come on.
Your air conditioning will not come on for two reasons:

the outside temperature is below 40F (4.5C),

or the refrigerant is too low or too high.
If the outside temperature is above 40F (4.5C) see
ªAir Conditioning Refrigerantsº in the Index.
Recirc Button
This button is used to recirculate much of the air
inside your vehicle. This setting is not available in defog.Outside Air Button
This button is used to bring in outside air.
Air Conditioning
On very hot days, open the windows long enough to let
hot inside air escape. This reduces the time the
compressor has to run, which should help fuel economy.
For quick cool
-down on very hot days, use
RECIRCULATE with the temperature knob all the way
in the blue area. If this and the A/C button pushed
setting is used for long periods of time, the air in your
vehicle may become too dry.
For normal cooling on hot days, use UPPER with the
temperature knob in the blue area. With the A/C button
pushed in and outside air 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 with the A/C button pushed in and the
outside air button pushed in. The system will bring in
outside air and direct it to your upper body, while
sending slightly warmed air to your lower body. You
may notice this temperature difference more at some
times than others.

3-4 Heating
On cold days use FLOOR and the outside air button
pushed in 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.
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.
Ventilation
For mild outside temperatures when little heating or cooling
is needed, use UPPER and outside air to direct air through
your vehicle. Your vehicle also has the flow
-through
ventilation system described later in this section.
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.
Air Conditioning with Automatic and
Auxiliary Temperature Control
(If Equipped)
With this system, you set a temperature. You can then
either let the system adjust airflow and force to maintain
the temperature, or you can manually adjust the flow
and force. The system works best if you keep your
windows closed while using it.

red) to raise the temperature. Turn it counterclockwise
(toward blue) to lower the temperature. The display will
show your selection for a few seconds, then the outside
temperature will show. If you push the knob the set
temperature will again be displayed for a few seconds,
then the outside temperature will show.
Passenger Temperature Knob
The right (PASS) knob
adjusts the air temperature
on the passenger's side so it
is warmer or cooler than the
temperature set by
the driver.
Turn the PASS knob clockwise (toward red) to raise the
temperature. Turn it counterclockwise (toward blue) to
lower the temperature. The passenger temperature will
not be shown in the display.Auto Button
For the most efficient operation you should press the
AUTO button and set the system temperature. The
system will select the best fan speed and airflow settings
to keep you comfortable. The air conditioning
compressor will run if the outside temperature is above
40
F (4.5
C). You may notice a delay of three to
four minutes before the fan comes on.
Off Button
Push the OFF button to turn the system off. The display
will show OFF and outside temperature. The system will
continue to automatically control air temperature to the
last set temperature.
Manual Control
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
desired airflow direction pushbutton. The system will
try to maintain the temperature you set using the mode
you select. The following suggestions will help the

Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.If you drive regularly in steep country, or if you're
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.

Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system
and transaxle. These parts can work hard on
mountain roads.

Know how to go down hills. The most important
thing to know is this: let your engine do some of the
slowing down. Shift to a lower gear when you go
down a steep or long hill.
CAUTION:
If you don't shift down, your brakes could get so
hot that they wouldn't work well. You would then
have poor braking or even none going down a
hill. You could crash. Shift down to let your
engine assist your brakes on a steep
downhill slope.

4-41 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.
