The air conditioning can operate in all modes. However, the air
conditioning will only function if the outside temperature is about 6ÉC
(43ÉF) or higher.
Since the air conditioner removes considerable moisture from the air
during operation, it is normal if clear water drips on the ground under
the air conditioner drain while the system is working and even after you
have stopped the vehicle.
²
MAX A/C-Uses recirculated air to cool the vehicle. MAX A/C is noisier
than A/C but more economical and will cool the inside of the vehicle
faster. Airflow will be from the instrument panel registers. This mode
can also be used to prevent undesirable odors from entering the vehicle.
²(Panel)-Distributes outside air through the instrument panel
registers. Heating and air conditioning capabilities are provided in this
mode. Push the A/C control in order to cool the vehicle below the
outside temperature. For added customer comfort, the system will
allow some airflow through the floor ducts in this mode.
²OFF (O)-Outside air is shut out and the fan will not operate. For short
periods of time only, use this mode to prevent undesirable odors from
entering the vehicle.
²
(Panel and floor)-Distributes outside air through the instrument
panel registers and the floor ducts. Heating and air conditioning
capabilities are provided in this mode. Push the A/C control in order
to cool the vehicle below the outside temperature. For added
customer comfort, when the temperature control knob is anywhere in
between the full hot and full cold positions, the air distributed through
the floor ducts will be slightly warmer than the air sent to the
instrument panel registers.
²
(Floor)-Distributes outside air through the floor ducts. Heating
and air conditioning capabilities are provided in this mode. Push the
A/C control in order to cool the vehicle below the outside temperature.
²(Floor and defrost)-Distributes outside air through the
windshield defroster ducts and the floor ducts. Heating and air
conditioning capabilities are provided in this mode. For added
customer comfort, when the temperature control knob is anywhere in
between the full hot and full cold positions, the air distributed through
the floor ducts will be slightly warmer than the air sent to the
windshield defrost ducts. If the outside temperature is about 6ÉC
(43ÉF) or higher, the air conditioner will automatically dehumidify the
air to reduce fogging. (Note that the A/C indicator does not illuminate
when this mode is selected.)

²(Defrost)-Distributes outside air through the windshield
defroster ducts. It can be used to clear ice or fog from the windshield.
If the outside temperature is about 6ÉC (43ÉF) or higher, the air
conditioner will automatically dehumidify the air to reduce fogging.
(Note that the A/C indicator does not illuminate when this mode is
selected.) For added customer comfort, the system will allow some
airflow through the floor ducts in this mode.
Cooling your vehicle with outside air
Cooling your vehicle with air conditioned outside air is quieter but less
economical than using recirculated air. It also has less cooling capacity.
In order to cool your vehicle using outside air:
1. Turn the mode selector to
,or.
2. Press the
A/C. (The indicator light will illuminate.)
3. Turn the temperature control knob to the left.
4. Turn the fan speed control to the position of your choice.
During periods of high humidity, vapor may be emitted from the air
outlets when using the A/C system with outside air. This can be
corrected by using MAX A/C to cool the vehicle.
²A/C control
This control is used to manually enable or disable the operation of the
air conditioning in all modes except
and.
When manual A/C is selected (ON) the indicator will be lit. When manual
A/C is selected (OFF) the indicator will not be lit.
In
and, if the outside temperature is about 6ÉC (43ÉF) or
higher, the air conditioner will automatically dehumidify the air to reduce
fogging. However, the A/C indicator will not illuminate.
²Defrost control
Refer toRear Window Defroster.

Operating tips
²In humid weather conditions, place the climate control system in
before driving. This will reduce fogging on your windshield. Once the
windshield has been cleared, operate the climate control system as
desired.
²To reduce humidity buildup inside the vehicle in cold weather
conditions, don't drive with the climate control system in the OFF or
MAX A/C position.
²To reduce humidity buildup inside the vehicle in warm weather
conditions, don't drive with the climate control system in the OFF
position.
²Under normal weather conditions, your vehicle's climate control
system should be left in any position other than MAX A/C or OFF
when the vehicle is parked. This allows the vehicle to ªbreatheº
through the outside air inlet duct.
²Under snowy or dirty weather conditions, your vehicle's climate
control system should be left in the OFF position when the vehicle is
parked. This allows the climate control system to be free from
contamination of outside pollutants.
²If your vehicle has been parked with the windows closed during warm
weather conditions, the air conditioner will perform more efficiently in
cooling the vehicle if driven for two or three minutes with the
windows open. This will force most of the hot, stale air out of the
vehicle. Once the vehicle has been ªaired outº, operate the climate
control system as desired.
²Do not place objects under the front seat that will interfere with the
airflow to the rear seats.
²Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
²Do not place objects over the defroster outlets. These objects can
block airflow and reduce your ability to see through your windshield.
Avoid placing small objects on top of the instrument panel. These
objects may fall down into the defroster outlets and block airflow, in
addition to damaging the climate control system.

To aid in side window defogging/demisting in cold weather conditions:
1. Select
2. Set the temperature control to full heat
3. Set the fan speed to High
4. Direct the outer panel vents towards the side windows
5. To increase airflow to the outer panel vents, close the central panel
vents.
Do not place objects on top of the instrument panel, as these
objects may become projectiles in a collision or sudden stop.
Dual Electronic Automatic Temperature Control (DEATC) system
(if equipped)
The Dual Electronic Automatic Temperature Control (DEATC) system
will maintain a selected temperature and automatically control air flow.
You can override the automatic operation with any of the override
controls.
The dual temperature zone feature allows the driver and front passenger
to set their own independent temperature set points for individual
comfort. The system uses common controls for air distribution and fan
speed for both driver and passenger.

When in AUTO mode and the weather is cool, the DEATC directs the
majority of the airflow to the floor area. The system will allow some
airflow out the windshield defroster ducts and the demister outlets to
reduce window fogging. Additionally, if the engine is not warm enough to
provide heat, the fan will operate at a low speed and the airflow will be
directed to the windshield or to the floor. The fan speed will start to
increase and the airflow location will change to the floor area.
When in AUTO mode, the DEATC system automatically controls the air
conditioning operation, the fan speed, the airflow direction and
determines whether outside or recirculated air is required.
If unusual conditions exist (i.e.-window fogging, etc.), the manual
override controls allow you to select airflow locations as necessary. To
return to full automatic control, press the AUTO control.
Single/dual electronic temperature zone
