Component Identification:

The multifunction steering wheel, used in combination with the instrument cluster (A1), serves to increase active driving safety in road traffic.
The driver can concentrate on the traffic without distraction when controlling and operating various vehicle components. The multifunction steering wheel allows the driver to operate and query the following systems:
^ Radio and navigation systems
^ Interior lights
^ Trip computer
^ ASSYST
^ Distronic
^ Telematics
^ Telephone
^ Steering wheel gear shift
^ Tire pressure loss warning

Function requirements:
^ Circuit 15 ON

Only systems and functions with which the vehicle is equipped are displayed. If a system is not installed, it is "skipped" when the system selection button (S110s3) on the left multifunction steering wheel button group (S110) is pressed.

The system selected by the user is displayed on the multifunction display (A1p13) in the instrument cluster (A1). In addition, the fanfare horns (H2) can be actuated by means of the impact plate of the multifunction steering wheel.

Only the trip computer has a last-mode function. When the user switches to this system, the basic display is not shown; instead, the system displays the submenu that was last selected.
