Special case: Driver door
If the driver door is not closed when the ATA is activated, the rear SAM control unit recognizes this state and stores the information "Driver door open" on the Control Area Network bus, class B (interior compartment) (CAN-B).
When the driver door is closed, it remains unlocked so that a transmitter key cannot be unintentionally locked in the vehicle. The ATA is activated and the information "Driver door open" is stored.

The windows and the tilting/sliding roof with code (414) Power glass tilting/sliding roof can be opened and closed with the transmitter key via the convenience opening/closing function.
On this convenience function the ATA can be in the activation phase or is already in the armed state The alarm is deactivated for the duration of the convenience function so that the motions of the windows and tilting/sliding roof do not trigger an alarm. After the convenience opening/closing function the ATA is reset to the same status as before the function
