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 lower left side of the
instrument panel, to release
the trunk lid.
Make sure the lockout feature is not activated. Also, the
remote trunk release will only work when the gearshift
lever is in PARK (P) or NEUTRAL (N).
Remote Trunk Release Lockout
Your remote trunk release is equipped with a lockout
feature to help prevent unauthorized entry into the trunk
when leaving the vehicle unattended. The switch is
located on the inside of the trunk lid, mounted to the
trunk lid latch.

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
To block out glare, you can swing down the visors. You
can also swing them to the side.
Visor Vanity Mirror
Lift the cover to expose the vanity mirror.
Illuminated Visor Vanity Mirror
(If Equipped)
This mirror is located on the passenger's side visor.
When you lift the cover, the light will turn on.
Accessory Power Outlet
The accessory power outlet
is located to the right of
the ashtray.
You can use it to plug in additional electrical
accessories. Be sure to follow the proper installation
instructions that are included with any electrical
accessory you install. The accessory power outlet is
protected by a fuse and has a maximum current level.

2-54 Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves into the
red area, the light comes on
and you hear a chime, your
engine is too hot! 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.
In ªProblems on the Road,º this manual shows what to
do. See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
This light comes on
briefly when you turn
your ignition on.
If this light comes on and stays on and you hear a chime,
the vehicle should promptly be pulled off the road and
the coolant level checked.
See ªEngine Coolantº in the Index. If there are visible
signs of steam, see ªEngine Overheatingº in the Index
before opening the hood. Have your vehicle serviced as
soon as you can.

Comfort Controls
This section tells you how to make your air system work
for you. The climate control system with air
conditioning uses ozone
-friendly R-134a refrigerant.
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 selects the force of air you want. Turn the
knob clockwise to increase fan speed and
counterclockwise to decrease fan speed. To turn the fan
off (which will also turn the climate control system off),
turn the knob all the way counterclockwise. In any other
setting, the fan will run continuously. The fan must be
on to run the air conditioning compressor.
Temperature Knob
The center knob regulates the temperature of the air
coming through the system.
Mode Knob
The right control knob changes the functions of
the system.
VENT : In this position most of the air comes
through the instrument panel outlets. A small amount of
air comes through the floor outlets. Set the center
control knob to the temperature desired.

3-4 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.
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 button pushed in. The system
will bring in outside air and direct slightly warmer air to
your lower body.
For quick cool
-down on very hot days, use VENT with
the temperature knob all the way in the blue area and the
A/C and recirculation buttons pressed. If this setting is
used for long periods of time, the air in your vehicle
may become too dry.
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.
Heating
On cold days, use FLOOR and the OUTSIDE AIR
button 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 outlets.
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 (0
F (
-18
C) or lower). An engine coolant
heater warms the coolant your engine and heating
system uses to provide heat. See ªEngine Coolant
Heaterº in the Index.

3-6 Rear Window Defogger (If Equipped)
The rear window defogger
uses a warming grid to
remove fog from the
rear window.
Press the defogger switch. The indicator light will glow.
The rear window defogger will turn itself off after about
10 minutes after the first time the button is pressed, and
after 5 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 VENT 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.

4-38 Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need
additional wiring. Check with your dealer. The arrows
on your instrument panel will flash whenever you signal
a turn or lane change. Properly hooked up, the trailer
lamps will also flash, telling other drivers you're about
to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind you
are seeing your signal when they are not. It's important
to check occasionally to be sure the trailer bulbs are
still working.
Driving On Grades
NOTICE:
Do not tow on steep continuous grades exceeding
6 miles (9.6 km). Extended, higher than normal
engine and transaxle temperatures may result
and damage your vehicle. Frequent stops are
very important to allow the engine and transaxle
to cool.
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don't shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around 45 mph (70 km/h) to reduce the
possibility of engine and transaxle overheating.
Pay attention to the engine coolant gage. If the indicator
is in the red area, turn off the air conditioning to reduce
engine load (see ªEngine Overheatingº in the Index).
