The system uses a radar sensor in the central air intake to monitor the road up to 200 m ahead. If you approach another vehicle that is travelling slower than your selected cruising speed, the system slows the engine or gently applies the brakes. This continues until the distance that you have preset is maintained. If heavier braking is required, the driver has to actively intervene. When the vehicle in front decelerates further, adaptive cruise control will continue to reduce your speed – even down to a halt. When the road ahead is free once more, the car automatically returns to your chosen cruising speed between 30 and 210 km/h. If selected by the driver, the integrated Stop & Go function automatically applies the brakes and then drives off again in congested traffic. For added safety, the integrated Porsche Active Safe (PAS) visually and audibly warns the driver that intervention is necessary in the event of a sudden decrease in distance and briefly tugs on the brakes. It can also intervene in the braking process and apply increased braking pressure according to the situation through to all-out emergency braking, if required.
Cruise control automatically regulates the speed of your vehicle for added driver comfort and safety on longer journeys.
