Perceived temperature
The climate control system regulates the climate in the passenger compartment based on perceived temperature, not actual temperature.
The selected passenger compartment temperature is based on the physical perception of the current ambient temperature, airflow speed, humidity, sunlight in the passenger compartment, etc.
The system has a sunlight sensor that detects which side of the vehicle the sunlight is shining on and adjusts the temperature accordingly. This means that the temperature of the air coming out of the vents may be different for the left and right sides, even if the temperature setting is the same for both sides.
