In the E-Class, the standard THERMATIC automatic climate control regulates the temperature you set. It is equipped with a combination filter and ventilation switch and allows separate settings for the driver and front passenger.

The THERMOTRONIC luxury automatic climate control system is available as an option (also with combination filter and air recirculation switch) and divides the interior of the E-Class into four individually controlled temperature zones. A computer processes large amounts of sensor data to achieve this, for example, measurement of the degree of sunlight entering the car. A 4-quadrant solar sensor controls the air flow and temperature for each of the four zones in the interior depending on the sunlight’s angle of incidence. A multifunction sensor also monitors the air humidity and the level of pollution in the outside air. Where necessary, recirculation mode is activated automatically.
