DISTRONIC PLUS displays in the speedometer
When you switch on DISTRONIC PLUS, triangle 2 shows the stored speed.
For design reasons, the speed displayed
in the speedometer may differ slightly from
the speed set for DISTRONIC PLUS.
If DISTRONIC PLUS detects a vehicle in front, the speedometer dial lights up between speed of the vehicle in front 1 and stored speed 2.
