Trunk
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.
Trunk Lock Release
To unlock the trunk from the outside, insert the door key
and turn it clockwise.
Remote Trunk Release
The TRUNK release button
is on the instrument panel
to the left of the steering
column. The transaxle
must be in PARK (P) or
NEUTRAL (N).
If the remote trunk release button does not open the
trunk, make sure the remote trunk release lockout switch
in the glove box is in the on position.

NOTICE:
Don't put papers or other flammable objects
into your ashtrays. Hot cigarettes or other
smoking materials could ignite them, causing
a damaging fire.
To use a lighter, push the center all the way in and let it
go. When it is ready, the center will pop back by itself.
Pull out the entire unit to use it.
NOTICE:
Don't hold a cigarette lighter in with your hand
while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overheat, damaging the
lighter and the heating element.
Sun Visors
Illuminated Visor Vanity Mirrors
(If Equipped)
When you open the cover to either the passenger's or
driver's visor vanity mirror, the lamps will turn on. The
brightness of the lamp can be adjusted by sliding the
switch up or down.
Dual Sun Visors
Each sun visor has two parts, so that both the windshield
and door glass can be shaded at the same time. To use
the dual sun visors, flip the first visor down and turn
toward the window. Then, flip the second visor down
toward the windshield.

2-64 Engine Coolant Temperature
Warning Light
This light will tell you
that your engine coolant
has overheated or your
radiator cooling fans are
not working.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn the engine off as soon as possible.
See ªEngine Overheatingº in the Index.
Engine Coolant Temperature Gage
(If Equipped)
If your vehicle is equipped
with the gage cluster, you
have a gage that shows the
engine coolant temperature.
If the gage pointer moves
into the red area, your
engine is too hot!
That reading means the same thing as the warning light.
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
The engine coolant temperature gage indicates the
coolant temperature in degrees Fahrenheit. The
Canadian instrument panels indicate the coolant
temperature in degrees Celsius.
See ªEngine Overheatingº in the Index.

Comfort Controls
This section describes how to operate your climate
control system. Your climate control system uses
ozone
-friendly R-134a refrigerant.
With these systems, you can control the heating, cooling
and ventilation in your vehicle. Your vehicle also has a
flow
-through ventilation system described later in
this section.
Electronic Touch Climate Control
C±43±0376±S
If your vehicle has this climate control system, the
following information tells you how it works.Fan Button
The FAN control is used to select the speed of the
blower fan and the force of air you want. There are four
speeds to choose from. Moving the lever between LOW
and HIGH will decrease or increase the fan speed. The
fan will be off when the system is off.
Temperature Lever
This lever adjusts the temperature of the air coming
through the system. Move the TEMPERATURE lever to
change the temperature of the air coming through your
outlets. Move the lever between COOL and WARM to
lower or raise the temperature.
Mode Controls
The buttons on your system allow you to choose
settings to deliver air through the lower, middle or
windshield outlets.
RECIRC: Press this button to limit the amount of
outside air entering your vehicle. This is helpful when
you are trying to cool the interior of the vehicle quickly,
or limit the amount of outside air entering your vehicle.
To turn off RECIRC, press the button again. If you
select FRONT defrost or BLEND while RECIRC is
selected, the system will automatically turn off RECIRC
to prevent fogging.

On sunny days, when the air is moderately warm or
cool, use BI
-LEV to deliver warm air to the floor and
cooler air to the middle instrument panel outlets. On
days like these, the sun may adequately warm your
upper body, but your lower body may not be warm
enough. To warm or cool the air delivered, adjust the
TEMPERATURE lever.
The amount of fresh air entering the vehicle is limited
when RECIRC is selected. This is helpful when you are
trying to cool the air in your vehicle or limit the air
entering the vehicle.
If your vehicle has the Dual Automatic Comfortemp
system and it is set for AUTO, on very hot days, the
system will automatically enter the RECIRC mode and
the temperature door will be positioned at the full cold
position for maximum cooling. If the system is not in
the AUTO mode, RECIRC should be selected to provide
maximum cooling. You can choose the extreme comfort
setting of 60
F (16
C), but the system will not cool any
faster by choosing the extreme comfort setting.
When the air conditioner is on, you may sometimes
notice slight changes in your vehicle's engine speed and
power. This is normal because the system is designed to
cycle the compressor on and off to keep the
desired temperature.Heating
If your vehicle has the electronic touch system, on
cold days, use HTR with the TEMPERATURE lever
toward WARM.
If your vehicle has the Dual Automatic Comfortemp
system, and on cold days, if the AUTO mode is selected,
the system will automatically direct the air toward the
floor and the temperature door will be positioned at the
full hot position. You can choose the extreme comfort
setting of 90
F (32
C) but the system will not warm up
any faster by selecting the extreme comfort setting. If
the outside temperature is cold, the fan will be delayed
to avoid blowing cold air. Pushing the FAN, AIR FLOW
or FRONT buttons will override this delay, turn off the
AUTO mode and change the fan speed.
With each system, outside air will be brought in and sent
through the floor outlets. The heater works best if you
keep your windows closed while using it.

3-8 Defogging and Defrosting
If you have the electronic touch system, adjust the
TEMPERATURE lever toward WARM and the FAN
lever toward HIGH.
If you have the Dual Automatic Comfortemp system,
use the FRONT button to defog or defrost the
windshield. By choosing this button, the airflow will be
directed at the windshield. Adjust your comfort level by
pressing the TEMP up or down arrow. The fan speed
will be controlled by the system. You can change the fan
speed by pressing the top of the FAN button to increase
speed, and the bottom of the button to decrease speed.
To reduce the chance of fogging your windows in cold
weather, using the electronic touch system, select HTR
to supply air through the floor outlets. Then move the
FAN lever to HIGH for a few moments before driving
away. This will blow moist air from the intake outlets
toward the floor, not the windshield. If you have the
Dual Automatic Comfortemp system, the AUTO setting
will do this for you. Manual operation of the automatic
comfortemp system in the FLOOR mode will also
supply air through the floor outlets.
Rear Window Defogger
C±43±0375±S
The lines you see on the
rear window warm the
glass. Press this button to
start warming your window.
After 10 minutes it will turn off by itself, or pressing the
button during the heating cycle will turn it off. If you
need additional warming time, push the button again.
The system will then operate for five minutes before
going off by itself.

3-10 Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use VENT (on the electronic touch
system or manual operation on the Dual Automatic
Comfortemp system) to direct outside air through your
vehicle. Air will flow through the middle instrument
panel outlets.
Your vehicle's flow
-through ventilation system supplies
outside air into the vehicle when it's moving. When the
vehicle is not moving, you can get outside air to flow
through by selecting any air choice (except the rear
window defogger) and any fan speed.
H±43±0384±N
Adjust the direction of
airflow by moving the
louvered vents.
H±43±0385±P
If you have the rear passenger comfortemp option,
you can adjust the direction of the airflow to the rear
seating area.

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 then shift to PARK (P).
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 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.
