Self Study Program 995303 – Adaptive Cruise Control in the Audi A8L

VAG SSP 995303. Adaptive Cruise Control is a new system designed to make driving easier and safer. This new system restricts speed and monitors the distance of the vehicle in front. Driver convenience is improved because fewer accelerator and brake pedal operations are required.
