Microwave Sensors: Notes
The microwave sensors monitor the vehicle interior. Movement is detected if the reflection (echo) of the microwaves changes. The sensitivity of the microwave sensors is adapted for different conditions (e.g. vehicle model, installation location of microwave sensors).
Two of the microwave sensors are installed on the inner door panel of the driver's door and front-passenger door. The other two additional microwave sensors are installed on the inside of the B-pillars.
