System*, there is also an air quality sensor in the
climate system's air intake.

Climate (p. 204)
Interior Air Quality System* (p. 208) Perceived temperature
The climate control system regulates the climate
in the passenger compartment based on per-
ceived temperature, not actual temperature.
The selected passenger compartment tempera-
ture 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.
