The multifunction steering wheel (MFL) serves to increase active driving safety in road traffic in combination with the instrument cluster. The driver can concentrate on the traffic without distraction when controlling and operating various systems.

Function requirements:

C. 15R On
No undervoltage or overvoltage

Function

The MFL allows the driver to operate and query all multimedia services (e.g. radio).

The following systems also can be operated via the MFL:

Interior illumination (IBL) (e.g. OFF delay times)
Exterior lights (ABL) (e.g. OFF delay times, daytime running lamps)
Trip computer (TRIP)
Active service system (ASSYST)
Tire pressure loss warning (RDW) (for code (477) Tire pressure loss warning)
Distronic (autonomous intelligent cruise control) (DTR) (only in active state, no operation) (for code (219) Distronic (DTR))
Telematic Alarm Identification on Demand (emergency call system) (TELE AID) (only ) (for code (359) TELE AID emergency call system)

The system selected by the user is displayed in the upper multifunction display of the instrument cluster. The left fanfare horn and the right fanfare horn can also be operated using the fanfare horn system button and the fanfare horn system button on the MFL, below the impact plate.

The TRIP includes a "last mode" function. When you switch to this system, the last selected submenu is displayed; in the others systems the user is guided to a defined entrance level.
