The rear window lift mechanisms are operated using switches (3/85-86) in the door panels.

When the window lift mechanisms are operated from the driver's position, data is transmitted from the driver's door module (3/126) via the controller area network (CAN) to the rear electronic module (REM) (4/58) which transmits a signal to the correct relay.

There is a switch in the driver's door module (DDM) to allow for child locking, where the windows can only be operated from the driver's position. When the function is active, information is transmitted via the controller area network (CAN) to the rear electronic module (REM) to disconnect the relay. The circuit for the rear switch is then broken.

When the child lock is activated, the lighting in the rear switches goes out.
