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.
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 lid:

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.
Remote Trunk Release
Press the remote trunk release button, located on the
driver's door, to release the trunk lid.
Make sure the remote trunk release lockout feature is
not activated. Also, the remote trunk release will only
work when either the ignition is off, the parking brake is
engaged or the vehicle speed is less than 2 mph (3 km/h).

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: Use 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.
UPPER: In this position 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.
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.
FLOOR: In this position most of the airflow
comes through the floor outlet. The rest of the air comes
through the windshield and side window vents. Set the
center knob to the desired temperature.

3-3
DEFOG: This position divides the airflow
between the floor outlets and the windshield defroster
vent. The air conditioning compressor will run
automatically in this position when it is needed to help
dry the air in the vehicle.
FRONT DEFROSTER: This position directs
most of the airflow through the window defroster vent.
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 Button
: 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 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 UPPER 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, open 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 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.

3-5 Rear Window Defogger
The rear window defogger
uses a warming grid to
remove fog from the
rear window.
Press the defogger button. The indicator light will glow.
The rear window defogger will turn itself off after about
ten 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 UPPER 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. Recirculation of the air is automatic
in MAX A/C.

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.

4-40
4. Reapply the regular brakes. Then apply your parking
brake and shift into PARK (P) for an automatic
transaxle or REVERSE (R) for a manual transaxle.
5. Release the regular brakes.
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 belt, 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.
Towing a Trailer (2.4L L4 Engine)
Your vehicle is neither designed nor intended to tow a
trailer if it is equipped with a 2.4L L4 (Code T) engine.

If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for about
10 minutes. If the warning doesn't come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there's still no sign of steam, idle the engine for
three minutes while you're parked. If you still have the
warning, turn off the engine and get everyone out of
the vehicle until it cools down.
You may decide not to lift the hood but to get service
help right away.Cooling System
When you decide it's safe to lift the hood, here's what
you'll see:
A. Coolant Surge Tank with Pressure Cap
B. Electric Engine Cooling Fans

5-11
CAUTION:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can injure you. Keep hands, clothing and tools
away from any underhood electric fan.
If the coolant inside the coolant surge tank is boiling,
don't do anything else until it cools down.
When the engine is cold, the coolant level should be at
or above FULL COLD. If it isn't, you may have a leak
in the radiator hoses, heater hoses, radiator, water pump
or somewhere else in the cooling system.
CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don't touch them. If you
do, you can be burned.
Don't run the engine if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage from running your engine
without coolant isn't covered by your warranty.
