Active cruise control with Stop&Go function: Introduction
The following text describes the Active Cruise Control with Stop&Go function (optional equipment 5DF).
The Active Cruise Control with Stop&Go function has been available since 2007. The Stop&Go function expands the familiar Active Cruise Control feature by the following functions:
- Distance and cruise control up to a standstill through engine or brake intervention
- Automatic driving off from a standstill after a short immobilization period (1 to 3 seconds)
- adaptive Dynamic Brake Control (F0x, F1x)
The set speed can be selected from 30 km/h to 180 km/h: in convenient steps of 10 or fine steps of 1. The set speed is displayed on the instrument panel (or alternatively on the Head-Up Display). Furthermore, it is also possible to choose between 4 distances.
