Perceived temperature
The climate control system regulates the cli- mate in the passenger compartment basedon perceived temperature, not actual tem-perature.
The selected passenger compartment tem- perature is based on the physical perception ofthe current ambient temperature, airflowspeed, humidity, sunlight in the passengercompartment, etc. The system has a sunlight sensor that detects which side of the vehicle the sunlight is shin-ing on and adjusts the temperature accord-ingly. This means that the temperature of theair coming out of the vents may be differentfor the left and right sides, even if the tem-perature setting is the same for both sides.
