The air conditioning operates in MAX A/C and when the A/C control is
depressed. However, the air conditioning will only function if the outside
temperature is about 4ÉC (40ÉF) 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.
Under normal 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.
²MAX A/C-Uses recirculated air to cool the vehicle. MAX A/C is noisier
than A/C modes but more economical and will cool the inside of the
vehicle faster. In this mode, the air conditioning will automatically
engage if the outside temperature is about 4ÉC (40ÉF) or higher and
the
A/CA/C indicator will automatically light. 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/CA/C control in order to cool the vehicle below the
outside temperature.
²OFF-Outside air is shut out and the fan will not operate. For short
periods of time only, use this mode to reduce undesirable odors from
entering the vehicle.
²
(Panel and floor)-Distributes outside air through the instrument
panel registers and the front and rear floor ducts. Heating and air
conditioning capabilities are provided in this mode. Push the
A/CA/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 front and rear floor ducts will be slightly
warmer than the air sent to the instrument panel registers.
²
(Floor)-Allows for maximum heating by distributing outside air
through the front and rear floor ducts. Heating and air conditioning
capabilities are provided in this mode. Push the

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 front and rear floor ducts will be slightly warmer than the air sent
to the windshield defroster ducts. If the outside temperature is about
4ÉC (40ÉF) or higher, the air conditioner will automatically dehumidify
the air to reduce fogging.
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 4ÉC (40ÉF) or higher, the air
conditioner will automatically dehumidify the air to reduce fogging.
However, the indicator will not light unless the A/C control is selected.
Cooling your vehicle with outside air
Cooling your vehicle with air conditioned outside air is quieter but less
economical than using air conditioned recirculated air. It also has less
cooling capacity and is not recommended for high outside temperatures.
In order to cool your vehicle using outside air:
1. Turn the mode selector to
(panel),(panel and floor) or
(floor).
2. Press the
A/C(A/C) selector. The indicator light on the A/C selector
will illuminate.
3. Turn the temperature control knob counterclockwise to COOL.
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.

Rear seat heating
Rear seat heating is provided through the floor ducts located under the
front seats. Airflow and temperature to the rear seating are regulated by
the main climate control system.
The rear passenger compartment air conditioning system (if equipped)
should be set to OFF, if rear heating is desired.
Operating tips
²In humid weather, selectbefore driving. This will reduce fogging
on your windshield. After a few minutes, select any desired position.
²To reduce humidity buildup inside the vehicle, don't drive with the
climate control system in the OFF position.
²Don't put objects under the front seat that will interfere with the
airflow to the second row seat floor ducts.

²Remove any snow, ice or leaves
from the air intake area (at the
bottom of the windshield under
the hood).
²If your vehicle has been parked with the windows closed during hot
weather, the air conditioner will do a much faster job of cooling if you
drive for two or three minutes with the windows open. This will force
most of the hot, stale air out of the vehicle. Then operate your air
conditioner as you would normally.
²When placing objects on top of your instrument panel, be careful to
not place them over the defroster outlets. These objects can block
airflow and reduce your ability to see through your windshield. Also,
avoid placing small objects on top of your instrument panel. These
objects can fall down into the defroster outlets and block airflow and
possibly damage your climate control system.
²If the air conditioner works well in MAX A/C, but not in any other
mode when the A/C control is selected, this may indicate that the
odor and particulate air filter (if equipped) needs to be replaced.
Do not place objects on top of the instrument panel, as these
objects may become projectiles in a collision or sudden stop.
Rear passenger compartment air conditioning system (if equipped)
This system allows the rear seat occupants to adjust their air
conditioning comfort level.

Turning the Rear A/C off:
To turn the Rear A/C off, turn the Rear Fan Control on the main climate
control system to OFF, or
turn the Rear Fan Control on the main climate control system to Rear
A/C and turn the Rear A/C Fan Control to 0.
For maximum cooling for the front seat passengers, set the rear fan
switch to the OFF (0) position.
Please note that the rear passenger air conditioning system is
designed for air conditioning purposes only, and does not heat the
rear compartment. Rear compartment heating is provided by the
underseat floor ducts. Refer to Rear Seat Heating.

Fan speed ()
When AUTOMATIC is pressed, fan
speed is adjusted automatically for
existing conditions. You can override
fan speed at any time. To control
fan speed manually, use the
thumbwheel to cancel automatic fan
speed operation. Rotate the
thumbwheel up for higher fan speed
or down for lower fan speed.
The display will show
to indicate
manual fan operation.
To return to automatic fan operation, press AUTOMATIC.
Manual override controls
The override controls allow you to:
²manually control where the airflow is directed
²manually control the air conditioning operation
²manually select between outside or recirculated air during air
conditioning operation
The air conditioning can operate in all modes except OFF. It will also
operate only when required when AUTOMATIC has been selected.
However, the air conditioning will only function if the outside
temperature is about 4ÉC (40ÉF) or higher.

Cooling your vehicle with outside air using override controls
Cooling your vehicle with air conditioned outside air using just the A/C
override control is quieter but less economical than using both the A/C
and the MAX control. It also has less cooling capacity and is not
recommended for high outside temperatures.
In order to cool your vehicle with outside air using the override controls:
1. Select the override control
(panel),(panel and floor) or

2. Press the
A/C(A/C) control. The indicator light on theA/C(A/C)
