The "since start" or "since reset" display screen for the average speed can be activated via the system selection button (S110s3) and scroll forwards and backwards button (S110s1) on the multifunction steering wheel.

The following information is required: 

• Travel time: calculated internally in the instrument cluster (A1).
• Mileage: calculated from the four wheel speeds. The wheel speeds are transmitted as a message on the engine compartment CAN from the ESP, SPS and BAS control module (N47-5) to the instrument cluster (A1).

It is normal for different values to be displayed in "since start" (short-distance memory) display screen and in the "since reset" (long-distance memory) display screen as both displays access different data records. The "Since start" display (short-distance memory) reacts much more sensitively to the current driving situation than the "Since reset" display (long-distance memory).
