Functions
The multifunction steering wheel (MFL), in combination with the multifunction display (A1p13) of the instrument cluster (A1), serves to enhance active driving safety in road traffic. The driver can concentrate on the traffic without distraction when controlling and operating various vehicle components. The MFL allows the driver to operate and call up the systems and their submenus: The number of menus is dependent on the vehicle equipment level. e. :
^ Cellular telephone
^ Audio
^ Navigation
^ Vehicle and setting configuration
^ Fault and warning messages (if applicable)
^ Tire pressure monitor

The selected system is displayed in the multifunction display of the instrument cluster.

The fanfare horns are operated via the impact plate of the multifunction steering wheel.

When changing to another system, the start screen of the selected system is always displayed and not the submenu last selected in this system.

Left multifunction steering wheel button group
The left multifunction steering wheel button group contains the system selection button (S110s3), OK button (S110s6) and the scroll forward/back button (S110s1). Each of the systems can be called with the system selection button. It is possible here to "scroll" forward and backward from system to system. It is also possible to "scroll" forward and backward with the scroll forward and backward button within a system, i.e. additional submenus can be called up. The OK button can be used to accept the selection.

Right multifunction steering wheel button group
The right multifunction steering wheel button group contains the accept/terminate phone call button (S111s3), and the buttons + and - for setting of specific functions and volume control (S111s1). A telephone call can be accepted or terminated with the accept/ terminate phone call button.

The buttons + and - for setting specific functions and volume control can be used to adjust the volume of the currently active system.

VCS [SBS] on button
The VCS [SBS] on button can be used to activate the voice control system (VCS [SBS]). An acoustic signal is emitted after activation has taken place.

"Back" and SBS off button
The "Back" and SBS off button is used to deactivate the voice control system.

Signal transmission
The signals are read in via the steering LIN by the steering column module (N80) and transferred to the chassis CAN.

Steering wheel gear shift
The following functions are possible using the left steering wheel gear shifter and right steering wheel gear shift
^ Preselection of shift range.
^ Shifting into a gear from which the vehicle can be easily accelerated or decelerated.
^ Direct shifting of all forward gears.

Transfer of shift signals
The left steering wheel gear shifter and right steering wheel gear shifter are read in via the steering LIN by the steering column module. The steering column module transfers the "Upshift" or "Shift down" signal to the chassis CAN. The ETC [EGS] control unit (N15/3) actuates the gear change.

Gear shifts which would lead to impermissibly high or low motor speeds are not carried out.
