manually increase or decrease the fan speed.
Keep pressing the up or down arrow on this switch until
the desired fan speed appears on the display.
Pressing the arrows will delete AUTO from the digital
display. The fan graphics with the fan speed bars will
be shown. To increase the fan speed so that more
air flows into the vehicle, press the up arrow on the fan
switch. To decrease the fan speed and airflow, press
the down arrow. The AUTO button must be pressed to

(Outside Air): Press this button to turn the
outside air mode on or off. When this mode is on,
outside air will circulate throughout your vehicle.
When the button is pressed, an indicator light in the
button will come on to let you know that it is activated.
The outside air mode can be used with all modes,
but cannot be used with the recirculation mode.
When in the AUTO mode, the system automatically
selects outside air instead of recirculation, as required,
to control the temperature in the vehicle. By pressing
outside air, the system will lock into the outside air
mode. Any adjustment to the air intake must then be
made manually. Outside air should be used when trying
to defrost or defog windows to help reduce moisture
inside of the vehicle.
If you are in city traffic, your vehicle is stopped and idling,
or the weather is hot, the system may switch from the
outside air mode to the recirculation mode. To prevent
the air inside of your vehicle from becoming stale, be sure
to return to the outside air mode periodically.
