Additional Information

- Pressing the "Auto REST" and "Auto REAR" buttons briefly starts automatic mode on the left and right.
- The sensor for measuring humidity in the cabin is located at the base of the rearview mirror. Additional sensors are also located here (e.g. light sensor).
- The servo motors for the temperature mixing flaps each actuate a cold and hot flap for the front and rear (linked).
Example: Cold flap OPEN max = Hot flap CLOSED max

- Engine speed/DFI control unit/CAN drive/gateway/CAN MMI/front OAU
- The humidity is measured by a sensor integrated in the rain-light-moisture sensor (located at the base of the rearview mirror). In addition to humidity, this sensor also records dew point temperature, the temperature of the windshield, sun intensity on the left and right and the angle of incidence.
