AIRFLOW MODE CONTROL OPERATION

Airflow Mode Automatic Control

Front
• The front climate control unit determines the front
mode actuator opening angle based on the target
temperature.
Rear
• When the rear control switch is off, the rear airflow mode control determines the rear mode actuator opening
angle using the target temperature for the rear which is calculated by the front climate control unit based on the
set temperature which has been set using the driver-side temperature setting dial.
• When the rear control switch is on, the rear airflow
mode control determines the rear mode actuator
opening angle using the rear target temperature
which is calculated by the front climate control
unit based on the set temperature which has
been set using the rear temperature setting dial.

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.
