Self Study Program 289 – Adaptive cruise control in the Audi A8

VAG SSP 289. Adaptive cruise control is a new system designed to assist drivers and offers a much wider range of functions than the conventional Tempomat.

Driver convenience is considerably enhanced, as fewer accelerator and brake pedal operations are required. Speed restrictions and safe distances are reliably observed and the flow of traffic thus better regulated.
