• The climate control unit determines the airflow mode based on the current air mix actuator opening angle and A/C compressor operating status. During A/C OFF mode, determined value used for the airflow mode is changed according to the temperature signals input from the evaporator temperature sensor.

Ambient temperature correction
• To improve windshield and door glass from fogging, airflow mode is fixed at HEAT/DEF when the ambient temperature is low. However, ambient temperature correction does not operate when the temperature is set at MAX COLD.
Engine coolant temperature correction (Warm-up correction)
• Switches the airflow mode after the engine is started in winter in accordance with the increase in engine coolant temperature to prevent discomfort caused by cold air blown towards the feet. The engine coolant temperature correction is performed only when the cabin temperature is 13 °C {55 °F} or less, or the cabin temperature is 23 °C {73 °F} or less and sunlight intensity is relatively low.
• The airflow modes can be switched by operating the MODE switch.
