MANUAL HEATING AND AIR CONDITIONING SYSTEM
(IF EQUIPPED)
1.Fan speed adjustment:Controls the volume of air circulated in the
vehicle.
2.Temperature selection:Controls the temperature of the airflow in
the vehicle.
3.Air flow selections:Controls the direction of the airflow in the
vehicle. See the following for a brief description on each control.
MAX A/C:Distributes recirculated air through the instrument panel
vents and center console vents (if equipped) to cool the vehicle. This
re-cooling of the interior air is more economical and efficient.
Recirculated air may also help reduce undesirable odors from entering
the vehicle. The temperature selection control will not adjust airflow
temperature when in MAX A/C mode.
:Distributes outside air through the instrument panel vents and
center console vents (if equipped).
