Convenience closing function with lock switch
Driver/passenger door
Actuation of the left front door lock switch (CF) (S86/1)/right front door lock switch (CF) (S87/1) triggers the central locking lock function. If the lock switch is pressed for longer than 1 s the left front door control module (N69/1)/right front door control module (N69/2) transmits the command for convenience closing to the CAN bus. The command is transferred as long as the lock switch is actuated. The overhead control panel control module (N70) actuates the sliding/pop-up roof convenience closing function.

The door control modules actuate the power window convenience closing function.

Convenience closing function with trunk lid lock switch
In this case the trunk lid lock switch (CF) (S88/2) is actuated and the CAN message for convenience closing is transmitted by the PSE control module (combined) (A37).

Convenience opening
The convenience opening function is accomplished by actuation of the lock switch. In addition the seat ventilation function (special equipment) is switched on for 5 minutes.
