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.

Engine Coolant Temperature Light
h -
TEMP
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.
In “Problems
on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.
Engine Coolant Temperature Gage
.. 1. TEMP
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.
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.

Comfort Controls
Manual Single Zone Climate Control
COMFORT CONTROL II
With this system, you can control the heating, cooling
and ventilation in your vehicle, The system works best if
you keep your windows closed while using it.
Fan Knob
The left knob selects the amount of air you want. To turn
the fan off, turn the knob to
OFF.
If the airflow seems very low when the fan knob is turned
to
the highest setting, regardless of the mode setting, your
passenger compartment air filter may need to be replaced. See “Maintenance Schedule”
in the Index.
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:
MAX: This setting recirculates much of the air inside
your vehicle and sends it through the instrument panel
outlets. The air conditioning compressor will run
automatically
in this setting unless the outside
temperature is below
40°F (4°C). (Even when the
compressor is running,
you can control the temperature.)
NORM: This setting brings in outside air and sends
it through the instrument panel outlets. The air
conditioning compressor will run automatically in
this setting unless the outside temperature
is below
40°F (4°C). (Even when the compressor is running,
you can control the temperature.)

BI-LEV This setting brings in outside air and directs
it two ways. Half of the air is directed through the
instrument panel outlets. Most of the remaining air
is
directed through the floor ducts and a little to the defrost
and side window vents. The air conditioning compressor
will run automatically in this setting unless the outside
temperature is below
40°F (4°C).
VENT This setting brings in outside air and directs it
through the instrument panel outlets.
HTR: This setting sends most of the air through the
ducts near
the floor. The rest comes out of the defroster
and side window vents.
BLEND: This setting allows half of the air to go to the
floor ducts and half to the defroster and side window
vents. The air conditioning compressor will run
automatically in this setting unless the outside
temperature is below
40 OF (4 O C) .
FRONT This setting directs most of the air
through
the defroster and side window vents. Some of
the air also goes to the floor ducts. The air conditioning
compressor will run automatically
in this setting unless
the outside temperature is below
40°F (4°C).
Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time for the
vehicle to cool down.
For a 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.
For normal cooling on hot days, use NORM with the
temperature knob in the blue area. 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-LEV and set the temperature knob to a
comfortable setting. The system will bring in outside air
and direct it
to your upper body, while sending slightly
warmed air to your lower body.
You may notice this
temperature difference more at some times than others.

Heating
On cold days, use HTR 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.
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 O C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See “Engine Coolant
Heater” 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.
To warm passengers while keeping the windows
clear, use
BLEND.
Dual ComforTemp Climate Control
(If Equipped)
I_ .
With this system, the driver and passenger can maintain
separate temperatures. The system works best if you
keep your windows closed while using it.
Fan Control
The left knob labeled FAN controls the fan speed selection.
If the airflow seems very low when the fan knob is turned
to the highest setting regardless
of the mode setting, your
passenger compartment air filter may need to be replaced. See “Maintenance Schedule’’ in the Index.
Driver’s Temperature Knob
The center knob sets the temperature for the driver’s
outlets.
Turn the knob toward red (clockwise) for warmer
air. Turn it toward blue (counterclockwise) for cooler air.

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 following four
ATR FLOW up and down arrows
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.

0 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.
WFRONT 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 lights 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.
RECIRC: This setting recirculates much of the air
inside your ve.hicle. 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.
