Perceived temperature
The climate system regulates passenger com-partment temperature based on the perceivedtemperature, not on the actual one.
The selected passenger compartment tempera-ture is based on a physical perception relating tothe current ambient temperature, air flow, humid-ity, sunlight in the passenger compartment, etc.
The system's sunlight sensor monitors the side ofthe car where sunlight is entering the passengercompartment. This means that the actual tem-perature may differ between the right and leftsides of the compartment, even if the tempera-ture setting is the same for both sides.
