?
(Recirculation): Press the left side of the button to
turn the recirculation mode on. An indicator light above
the button comes on to show that it is on. The air inside
the vehicle is recirculated through the climate control
system and throughout the vehicle, not from outside.
This helps to limit the odors entering the vehicle and
maximize air conditioning performance. The recirculation
mode cannot be used while in defrost, defog, or floor
mode. If recirculation is selected while in these modes,
the indicator light flashes three times to let you know
that it is not allowed. Use this mode only when it is
needed for comfort, since window fogging occurs if
the air conditioning compressor is not engaged.

Press to cancel the auto recirculation feature. Each
time the vehicle is started, the system reverts to the auto
recirculation function.
When the weather is cool or damp, operating the system
in recirculation for extended periods of time can cause
fogging of the vehicle's windows. To clear the fog, select
either defog or defrost. Make sure the air conditioning
is on.

(Air Conditioning): Press to turn the air conditioning
on or off. A light above the button comes on while the
air conditioning is on.
When air conditioning is selected or in AUTO mode, the
system runs the air conditioning automatically to cool
and dehumidify the air entering the vehicle.
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for the
vehicle to cool down. Then keep the windows closed for
the air conditioner to work its best.
On cool, but sunny days while using manual operation
of the automatic system, use bi-level to deliver warm air
to the floor and cooler air to the instrument panel outlets.
To warm or cool the air, press
temperature setting.
In AUTO mode the system cools and dehumidifies the
air inside the vehicle. Also, the system maximizes its
performance by using recirculation as necessary.
Heating: On cold days when using manual operation
of the automatic system, choose floor mode to deliver air
to the floor outlets. To warm or cool the air delivered,
adjust the temperature to the desired setting.
To use the automatic mode, turn the knob to AUTO and
adjust the temperature by pressing
