Airflow Mode Automatic Control
• The climate control unit uses the present opening angle of the air mi actuator and the control condition of the
A/C compressor to determine the airflow mode. When the A/C compressor is in OFF mode, the climate control
unit varies the determined value of airflow mode according to the temperature signals received from the
evaporator temperature sensor.

Correction
Ambient temperature correction (European (L.H.D. U.K.) specs.)
• To improve windshield and front door glass from fogging, airflow mode is fied at HEAT/DEF when the ambient
temperature is low. However, ambient temperature correction does not operate when the temperature is set at
MAX COLD. (temperature setting dial is turned to the left)
Coolant temperature correction
• To prevent uncomfortable draughts of cold air blowing around the driver’s feet soon after the engine is started
in winter, airflow mode is switched from DEFROSTER to HEAT/DEF to HEAT mode to match the rise in engine
coolant temperature. This control only operates when the passenger compartment temperature is below 13° ° ° ° C
{55° ° ° ° F}, or when the passenger compartment temperature is below 23° ° ° ° C {73° ° ° ° F} and sunlight intensity is
comparatively low.
