i-Dual Climate Control System (With navigation system)
WARNING: This page is about a different car, the 2008 Acura TL and 2007 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.
This system automatically controls the temperature and the vent mode of the air direction to the driver and passenger's side depending on the angle of the sun, and the direction of the vehicle. It calculates information such as date, time, longitude, and latitude from the navigation system, as well as the irradiate strength of the sun from the sunlight sensor, to determine the appropriate mode position and temperature to be directed to each side.
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 a vehicle without navigation.
