Initial fan speed control for cooling/heating

▶

Cooling start control
When the intake temperature sensor indicates over 35°C, the driver might feel uncomfortable

by the air flow from the vent. Therefore, at the initial operation stage, the hot air is discharged to the

windshield (DEF mode) for about 5 seconds.

-

Heating start control

When the engine coolant temperature is low or the wind temperature is not warmed up sufficiently,

the driver might feel uncomfortable by the air flow from the vent. Therefore, the fan speed is set to the

1st stage and the cool air is sent to the windshield until the coolant temperature increases to the

proper level (DEF mode). As the engine coolant temperature goes up, the mode is changed to

Defrost & Foot mode or AUTO mode to increase the speed of blower motor. This control is cancelled
when the output value of the water temperature sensor is approximately 62℃. However, the

control time must not exceed 10 minutes.

(4) Air source control

The air source selection is made by the intake actuator. The driver can see the air source mode through

the switch's indicator and the LCD display.

mode is switched

between the fresh air and recirculation alternatively each time the switch is pressed.

Auto control

▶

In auto mode, the basic setting for the air source is fresh air. When the ambient temperature is high

during cooling,

the air source is changed from fresh air to recirculation to lower the temperature.

Control by vehicle speed (heating)

▶

The air source selection is controlled in accordance with the vehicle speed while driving. Operating

conditions and control process are as follows:

AUTO mode

When the vehicle speed is 45 km/h or lower in fresh air mode, the air source door is open 30% of its

maximum opening. If the vehicle speed is 65 km/h or more, then

the air source door is completely open.

However, the ambient temperature should be 0°C or less, coolant temperature 62°C or less

and the electric fan 7.5V or higher.
