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.
•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 restricted to instrument panel registers. This
mode can also be used to prevent undesirable odors from entering the
vehicle. When placed in MAX A/C, the A/C indicator will be
illuminated and cannot be manually disabled.
•
(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.
•OFF (0)-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.
•
(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.
•
(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.
•
(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 6°C (43°F) 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.)

•(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 6°C (43°F) 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
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.
•A/C control
This control is used to manually enable or disable the operation of the
air conditioning in all modes except
,and MAX A/C.
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 6°C (43°F) or
higher, the air conditioner will automatically dehumidify the air to reduce
fogging. However, the A/C indicator will not illuminate.
When placed in MAX A/C, the A/C indicator will illuminate automatically
and cannot be manually disabled.

Operating tips
•In 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.
•To 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.
•To reduce humidity buildup inside the vehicle in warm weather
conditions, don’t drive with the climate control system in the OFF
position.
•Under 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“breathe”
through the outside air inlet duct.
•Under 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.
•If 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“aired out”, operate the climate
control system as desired.
•Do not place objects under the front seat that will interfere with the
airflow to the rear seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
•Do 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.

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.
If unusual conditions exist (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.
