Trunk
To unlock the trunk from the outside, insert the key and
turn the trunk lock cylinder or use the remote keyless
entry transmitter (if equipped).
When closing the trunk, close from the center to ensure
it fully latches.
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.
CAUTION: (Continued)
CAUTION: (Continued)
Turn the fan on your heating or cooling
system to its highest speed with the setting
on any airflow selection except MAX. 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 (If Equipped)
Pull upward on the remote
release handle, located on
the floor near the left side of
the driver's seat, to release
the trunk lid.

Temperature Knob
The center knob changes the temperature of the air
coming through the system. Turn this knob toward red
(clockwise) for warmer air. Turn it toward blue
(counterclockwise) for cooler air.
Mode Knob
The right knob has several settings to control the
direction of airflow. For each setting, select the
temperature that is comfortable.
MAX: For maximum cooling use this setting to
recirculate much of the air inside your vehicle and send
it through the instrument panel outlets. The air
conditioning compressor will run automatically in this
setting when it is needed to help cool the air in the
vehicle. Operation in this mode during periods of high
humidity and cool outside temperatures may result in
increased window fogging. If window fogging is
experienced, select the defrost mode.
VENT: This setting brings in outside air and
directs it through the instrument panel outlets.
BI-LEVEL: This setting brings in outside air and
directs it two ways. Some air is directed through the
instrument panel outlets. Most of the 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 defroster and side
window vents.
DEFROST: This setting directs most of the air
through the defroster and side window vents. Some of
the air goes to the floor ducts. The air conditioning
compressor will run automatically in this setting when it
is needed to help dry the air in the vehicle. The indicator
light will also be on in the setting.
Air Conditioning Compressor Button
Press the A/C button to operate the air conditioner
compressor. The indicator light above the button will
glow when the air conditioning compressor is running.
You don't have to press the button to run the compressor
in max or defrost.
Page 140 of 357
3-5
It is normal for the A/C indicator light to come on while
in DEFROST.
Running the compressor will help reduce vehicle
interior fogging.
Air Conditioning (If Equipped)
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 cook down, which should help
fuel economy.
For quick cool down on very hot days, use max with the
temperature knob all the way in the blue area. If this
setting is used for long periods of time, the air in your
vehicle may become too dry. The best cool down
happens if you start in one of the other modes and then
switch to max.
For normal cooling on hot days, use vent with the
temperature knob in the blue area and the A/C 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 and the A/C button pushed in. The system will
bring in outside air and direct slightly warmer air to
your lower body. You may notice this temperature
difference more at some times than others.
Heating
On cold days, use floor 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.
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 (0F (
-18C) 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.
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.

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.
CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have to
do all the work of slowing down. They 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. Always have your engine
running and your vehicle in gear when you
go downhill.
Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine
and transaxle, and you can climb the hill better.
Stay in your own lane when driving on two
-lane
roads in hills or mountains. Don't swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.
As you go over the top of a hill, be alert. There could be
something in your lane, like a stalled car or an accident.
You may see highway signs on mountains that warn of
special problems. Examples are long grades, passing or
no
-passing zones, a falling rocks area or winding
roads. Be alert to these and take appropriate action.

4-42 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 (Except Models with
2.4L L4 Engine and 4
-Speed
Automatic Transaxle)
Do not tow a trailer if your vehicle is:
equipped with a 2.2L L4 (Code 4) engine or
equipped with a manual transaxle or a three
-speed
automatic transaxle.

A. Coolant Surge Tank with Pressure Cap
B. Electric Engine Cooling Fan
Page 220 of 357
5-12
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
the FULL COLD mark. 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.
Page 221 of 357
5-13
NOTICE:
When adding coolant, it is important that you
use only DEX
-COOL (silicate-free) coolant.
If coolant other than DEX-COOL is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the
use of coolant other than DEX
-COOL is not
covered by your new vehicle warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fan is running. If the
engine is overheating, the fan should be running. If it
isn't, your vehicle needs service.
How to Add Coolant to the Coolant
Surge Tank
If you haven't found a problem yet, but the coolant level
isn't at the FULL COLD mark, add a 50/50 mixture of
clean, drinkable water and DEX
-COOL coolant at
the coolant surge tank, but be sure the cooling system,
including the coolant surge tank pressure cap, is cool
before you do it. See ªEngine Coolantº in the Index for
more information.
