Interior Air Quality System* (p. 200)
Perceived temperature
The climate control system regulates the climatein the passenger compartment based on per-ceived temperature, not actual temperature.
The selected passenger compartment tempera-ture is based on the physical perception of thecurrent ambient temperature, airflow speed,humidity, sunlight in the passenger compartment,etc.
The system has a sunlight sensor that detectswhich side of the vehicle the sunlight is shiningon and adjusts the temperature accordingly. Thismeans that the temperature of the air coming outof the vents may be different for the left and rightsides, even if the temperature setting is the samefor both sides.
