Adaptive Cruise Control

Adaptive cruise control keeps a set gap to the car ahead using front radar, and it is fussier than regular cruise about weather and sensor cleanliness. When it drops out or refuses to engage, the dashboard usually shows a specific message rather than a generic light. This section covers what those messages mean, why the system disables itself in fog, snow, and heavy spray, and how a covered or misaligned radar changes the way your car brakes and accelerates. You will learn the difference between a temporary block and a stored fault, how radar calibration works after a windshield or bumper repair, and simple checks that fix the majority of complaints before they reach a workshop.
