This mode keeps outside air from entering the
vehicle. It can be used to reduce outside air
and prevent odors from entering your vehicle.
Recirculation may also help cool the air inside your
vehicle more quickly once the temperature inside
the vehicle is less than the outside temperature.
The recirculation mode cannot be used with floor,
defrost, or defogging modes. If you try to select
recirculation in one of those modes, the indicator
light will flash three times and turn off. The air
conditioning compressor will also come on when
this mode is activated. While in recirculation mode
the windows may fog when the weather is cold and
damp. To clear the fog, select either the defog or
defrost mode and increase the fan speed.
Recirculation mode can be turned off by pressing
the button again, or turning off the engine.
Temperature Control: Rotate the thumbwheels
up or down to increase or decrease the
temperature on the driver's side or the passenger
side to the vehicle for the dual zone system.
