The air intake control button is used to switch
the air intake between the OUTSIDE AIR
mode and RECIRCULATED AIR mode.
With the button in the OUTSIDE AIR mode,
the OUTSIDE AIR mode indicator light will
come on and the system will take fresh out-
side air into the vehicle.
If quick circulation of cooled air is desired,
push the air int
ake control button for RECIR-
CULATED AIR. The RECIRCULATED AIR
mode indicator light will come on. For normal use, it is best to keep the air in-
take control button set to OUTSIDE AIR
mode. If recirculated air is used during heat-
ing, the windows will fog up more easily.
If the engine coolant temperature becomes
extremely high, the RECIRCULATED AIR
mode is automatically selected. This is not
a malfunction. When the engine coolant
temperature is lowered, the previous mode
resumes.
