With the exception of the fuel tank flap the vehicle can be locked or unlocked centrally with the interior central locking and ATA function display switch (N72/1s6)  . Theanti-theft alarm (ATA)  is not activated or deactivated.

The command to unlock or lock is sent via CAN by operating the interior switch. The PSE control module (combined functions) (A37)  receives this command and locks or unlocks pneumatically. The interior switch is enabled by the locking and unlocking functions of central locking via CAN.

When locking  with the interior central locking switch (N72/1s6)  the signals from the door contact switches are evaluated.
