The system uses a radar sensor in the front 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 pre-set is attained. If heavier braking is required, the driver has to actively intervene. If the vehicle in front continues to slow down, adaptive cruise control will keep on reducing your speed, right down to a halt if necessary. When the road ahead is free again, the car automatically returns to your chosen cruising speed between 30 to 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
Cruise control automatically regulates the speed of your vehicle for added driver comfort and safety on longer journeys.
