Trunk
CAUTION:
It can be dangerous to drive with the trunk 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 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 door key
and turn it. You can also press the car symbol on your
remote keyless entry transmitter.
Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft
-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition and transaxle. And remember to lock the doors.

2-52 Trunk Convenience Net (If Equipped)
Your vehicle may have a convenience net. You'll see it
on the back wall of the trunk.
Put small loads, like grocery bags, behind the net. It can
help keep them from falling over during sharp turns or
quick starts and stops.
The net isn't for larger, heavier loads. Store those in the
trunk as far forward as you can.
You can unhook the net so that it will lie flat when
you're not using it.
Ashtrays and Lighter
The center front ashtray is located just below the
instrument panel's comfort controls at the front of the
console, behind the front compartment storage door. To
remove the ashtray, open the storage door. Then open
the small black door, lift up on the ashtray and pull
it out.
The rear ashtray is located within a small door at the
rear of the console. Push on the right side of the door.
The ashtray will then rotate to the right for usage. You
can only access the ashtray by pushing on the door's
right side. To remove the ashtray, push down on the
snuffer located in the middle of the ashtray and lift
it out.
NOTICE:
Don't put papers and other things that burn into
your ashtrays. If you do, cigarettes or other
smoking materials could set them on fire,
causing damage.
To use the lighter, just push it in all the way and let go.
When it's ready, it will pop back by itself.
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.

2-65 Low Traction Light
This light will also come
on when the Traction
Control System is limiting
wheel spin.
You may feel or hear the system working, but this is
normal. Slippery road conditions may exist if the low
traction light comes on, so adjust your driving
accordingly. The light will stay on for a few seconds
after the traction control system stops limiting wheel
spin. See ªTraction Control Systemº in the Index.
The low traction light also comes on briefly when you
turn the ignition key to RUN. If the light doesn't come
on then, have it fixed so it will be there to tell you when
the Traction Control System is active.
Engine Coolant Temperature Light
This light tells you that your
engine coolant has
overheated or your radiator
cooling fan is not working.
The light will come on briefly when your ignition is
turned on to show you that it is working.
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 ªProblems on the Roadº section of this manual
shows what to do. See ªEngine Overheatingº
in the Index.

2-66 Engine Coolant Temperature Gage
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 ªProblems on the Roadº section of this manual
shows what to do. See ªEngine Overheatingº
in the Index.
Low Coolant Warning Light
If the LOW COOLANT
light comes on, your system
is low on coolant and the
engine may overheat. See
ªEngine Coolantº in the
Index and have your vehicle
serviced as soon as you can.
The light will come on briefly when your ignition is
turned on to show you that it is working properly.
Low Tire Light
The low tire inflation
monitor system can alert
you to a large change in the
pressure in one tire.

Heating
On cold days, use HTR with the temperature knob and
lever 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 VENT to direct outside 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 FRONT with
the temperature knob all the way in the red area.
For maximum defroster performance, set both driver and
passenger temperature controls to the warmest setting.
To warm passengers while keeping the windows clear,
use BLEND.
Dual Automatic ComforTemp Climate
Control (If Equipped)
With this system, you set a temperature. You can then
either let the system automatically control airflow
direction and force to maintain the temperature, or you
can manually adjust it. The system works best if you
keep your windows closed while using it.
Automatic Control
For the most efficient operation, you should set the
system temperature and press AUTO. 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
C). You may
notice a delay of two to three minutes before the fan
comes on at start up in cool weather.

Temperature Control
The TEMP switch sets the temperature for the entire
system when the light on the DUAL button isn't lit. If
the DUAL button light is lit, this master temperature
control sets the temperature for the driver only. Press the
up arrow to raise the temperature and press the down
arrow to lower the temperature. The display will show
your selection for a few seconds, then the outside
temperature will be displayed. If you push the AUTO
button, the system will control the fan speed and airflow.
Passenger's Temperature Control
The PASSENGER CONTROL buttons with the arrows
adjust the temperature on the passenger's side so it is
warmer or cooler than the temperature set by the driver.
Push the DUAL button so that the indicator light is lit.
Press the right arrow button to raise the temperature.
Press the left arrow button to lower the temperature. The
display will not show the passenger's temperature, only
that of the driver. Indicators in the passenger control
section will show passenger temperature relative to the
driver's set temperature.

The amber light indicates the same temperature as
set for the driver.

The red lights indicate a warmer temperature than
that of the driver.
The blue lights indicate a cooler temperature than
that of the driver.
Manual Control
If you prefer to manually control the heating, cooling
and ventilation in your vehicle, you can select airflow
direction, fan speed, outside or recirculated air and air
compressor operation with the following buttons:
AIR FLOW: This control has several settings to control
the direction of airflow when the system is not in AUTO.
To access the various modes available, continue to press
the AIR FLOW rocker button up or down until the
desired mode appears in the display:

WINDSHIELD/FLOOR: This setting directs half
of the air to the floor ducts and half to the defroster
and side window vents.

MID/FLOOR: This setting directs half of the air
through the instrument panel outlets. Most of the
remaining air is directed through the floor ducts and
a little to the defroster and side window vents.

MID: This setting directs air through the instrument
panel outlets.

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.

3-6
FRONT: This setting brings in outside air and
directs most of the air through the defrost vent. Some of
the air also goes to the floor ducts and the side window
defogger outlets. The indicator on the button will light
and WINDSHIELD will be lit in the display. The air
conditioning compressor will run automatically in
this setting unless the outside temperature is below
40
F (4
C).
VENT: This pushbutton turns the air conditioning
compressor on and off. The indicator is lit when the
compressor is turned off. Recirculation is not permitted
when the compressor is off. The system will try to
control the temperature automatically, but without
the compressor.
VENT is not permitted in FRONT defrost mode. If the
VENT button is pushed while in FRONT defrost mode,
the indicator will light for one second and then turn off.
RECIRC: This setting recirculates much of the air
inside your vehicle. This setting is not permitted in
FRONT defrost mode and is only permitted in WINDSHIELD/FLOOR mode if the compressor is
turned on. The indicator light will be lit when
recirculation is engaged, but will light for one second
and then turn off if selected when not permitted.
Heating (Engine Coolant Heater)
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.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows. To defrost the windows quickly, press the
FRONT button; set the temperature to 90
F (32
C),
select high fan speed and turn the DUAL button off. To
warm passengers while keeping the windows clear, push
the AIR FLOW button until WINDSHIELD/FLOOR
appears in the display. Select fan speed for comfort and
windshield clearing performance.

3-24 Backglass Antenna
Your AM-FM antenna is integrated with your rear
window defogger, located in the rear window. Be sure
that the inside surface of the rear window is not
scratched and that the lines on the glass are not
damaged. If the inside surface is damaged, it could
interfere with radio reception. Also, for proper radio
reception, the antenna connector at the top
-center of the
rear window needs to be properly attached to the post on
the glass.
NOTICE:
Do not try to clear frost or other material from
the inside of the rear window with a razor blade
or anything else that is sharp. This may damage
the rear defogger grid and affect your radio's
ability to pick up stations clearly. The repairs
wouldn't be covered by your warranty.
Because this antenna is built into your rear window,
there is a reduced risk of damage caused by car washes
and vandals.
If you choose to add a cellular telephone to your vehicle,
and the antenna needs to be attached to the glass, be sure
that you do not damage the grid lines for the AM
-FM
antenna. There is enough space between the lines to
attach a cellular telephone antenna without interfering
with radio reception.
On cars equipped with the rear window defogger and
built
-in antenna, the defogger grid serves as a radio
antenna. Do not apply aftermarket glass tinting to the
back glass. The metallic film in some tinting materials
will interfere with or distort the incoming radio
reception. Care must be taken when cleaning the rear
window because breaks in the resistive material heating
element will adversely affect radio performance and
defogger performance. See your dealer for details.
