Engine Exhaust
CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can't see or
smell. It can cause unconsciousness and death.
You might have exhaust coming in if:

Your exhaust system sounds strange
or different.

Your vehicle gets rusty underneath.

Your vehicle was damaged in a collision.

Your vehicle was damaged when driving over
high points on the road or over road debris.

Repairs weren't done correctly.

Your vehicle or exhaust system had been
modified improperly.
If you ever suspect exhaust is coming into
your vehicle:

Drive it only with all the windows down to
blow out any CO; and

Have your vehicle fixed immediately.
Running Your Engine While
You're Parked
It's better not to park with the engine running. But if you
ever have to, here are some things to know.
CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
ªEngine Exhaust.º
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even
if the fan is at the highest setting. One place
this can happen is a garage. Exhaust
-- with
CO
-- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be a blizzard.
See ªBlizzardº in the Index.

Comfort Controls
Dual ComforTemp
Climate Control
With this system, the driver and passenger can maintain
separate temperatures in their seating areas. The system
works best if you keep your windows closed while using it.
FAN:
Turn the knob clockwise toward HI to increase fan
speed and counterclockwise toward LO to decrease
fan speed. The fan must be turned on for the air
conditioning compressor to operate.
If the airflow seems very low when the fan is adjusted
to the highest setting regardless of the mode setting,
your passenger compartment air filter may need to be
replaced. See ªMaintenance Scheduleº or ªPassenger
Compartment Air Filterº in the Index.
OFF: To turn off the fan, turn the knob all the way
counterclockwise to off.
DRIVER (Driver's Side Temperature):
The lever on the left adjusts the air temperature on the
driver's side outlets independent of the temperature set by
the passenger. Slide the lever up to raise the temperature.
Slide the lever down to lower the temperature.
PASSENGER (Passenger's Side Temperature):
The lever on the right adjusts the air temperature on the
passenger's side independent of the temperature set by
the driver. Slide the lever up to raise the temperature.
Slide the lever down to lower the temperature.

3-4 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.
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, air conditioning and temperature.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 switch 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. The air conditioning compressor
will run automatically in this setting unless the outside
temperature is below 40
F (4
C).
MID/FLOOR (Instrument Panel/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 (Instrument Panel): 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. When in this setting and the
RECIRC setting, the windows can fog up. See
ªRecirculationº in the Index.

3-5
FAN: Press the up arrow to increase fan speed and
the down arrow to decrease fan speed. The fan must be
turned on for the air conditioning compressor to operate.
TEMP (Temperature): The TEMP switch sets the
temperature for the entire cabin when the light on the
DUAL light button isn't lit. When the DUAL button
light is lit, the TEMP switch sets the temperature for
the driver's side 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.
VENT: This setting 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 briefly and then turn off.RECIRC (Recirculation): 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 air conditioning
compressor is turned on. The indicator light will be lit
when recirculation is engaged, but will light briefly and
then turn off if selected when not permitted.
Operating the climate control system in the RECIRC
mode may cause fogging of the vehicle's windows when
the weather is cold and damp. To clear the fog, switch
the system to either WINDSHIELD/FLOOR or
WINDSHIELD mode and increase the fan speed. To
avoid refogging of the windows, operate the system with
RECIRC off.
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 seen on the
display. The air conditioning compressor will run
automatically in this setting unless the outside
temperature is below 40
F (4
C).

3-7 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.
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 levers 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 VENT with the
temperature levers 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 levers 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.
Defogging and Defrosting
If you have the Dual Comfortemp Climate Control, your
system has two settings for clearing the front and side
windows. To defrost the windows quickly, turn the mode
knob to the defrost setting and turn 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.
If you have the Dual Automatic Comfortemp Climate
Control, 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.

3-8 Rear Window Defogger
Dual ComforTemp

Climate ControlDual Automatic
ComforTemp

Climate Control
The rear window defogger uses a warming grid to
remove fog from the rear window. Press the button to
turn the rear defogger on. It will turn off after about
15 minutes. If you turn it on again, the rear defogger
will only run for about seven and a half minutes before
turning off. You can also turn it off by pressing the
button again.
NOTICE:
Do not attach anything like a temporary vehicle
license or decal across the defogger grid.
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.
