SYSTEM DESCRIPTION

1. GENERAL

(a) The air conditioning system has the following features:

The optional multi-zone automatic climate control system (controlled by the neural network) is available on this vehicle. When the 4-ZONE switch is ON, the temperature, airflow mode and airflow volume of each of the 4 seats (driver, front passenger, rear left, rear right) is automatically adjusted.

As a standard, the front seat independent temperature climate control system (controlled by the neural network) is in this vehicle. A non-sliding type film damper is used to provide independent airflow volume for the right and left side of the vehicle.

The multi-zone automatic climate control system has a 4-ZONE switch, and the front seat independent temperature climate control system has a DUAL switch.

The registers on the center pillars help improve airflow to the rear seats.

For vehicles with the rear cooler, there are roof and roof side air ducts, and independent temperature and airflow mode adjustments are automatically performed.

The rear cooler unit has a rear seat independent temperature climate control system, an odor filter for the air purification function, and a cool box.

For the long body VIP specification, an infrared ray sensor unit is installed. The infrared ray sensor unit detects the body temperature of the rear seat passenger, compares the body temperature to a specified setting, and attempts to decrease the temperature difference.

The Positive Temperature Coefficient (PTC) heater system contains a PTC heater that heats the air that has passed through the heater core to ensure the proper heater performance.

A compact, lightweight, and highly efficient straight flow (full-path flow) aluminum heater core is used.

The micro dust and pollen filter control is used to remove pollen in the area around the upper areas of the driver and front passenger seats.

The air conditioning amplifier is equipped with a self diagnosis function. If there is a malfunction in the system, it stores the DTCs (Diagnostic Trouble Codes) in its memory.
