Climate Control










System Description




i-Dual Climate Control System
This system automatically controls the temperature and the vent mode for the driver and passenger's sides depending on the angle of the sun and the direction of the vehicle. The system receives information such as date, time, longitude, and latitude from the navigation system, and it determines the irradiate strength of the sun from the sunlight sensor.

In the event that the navigation system malfunctions, or when driving in areas where the navigation cannot determine the vehicle position (non-coverage areas, tunnels, etc.), the climate control system will operate the same as one in a vehicle without navigation.
