In vehicles equipped with a head-up display, a symbol will be displayed on the windshield as long as the time interval to the vehicle ahead is shorter than the set time interval. However, the Show Driver Support function must be activated under Settings in the vehicle's menu system.

Distance Alert is active at speeds above 30 km/h (20 mph) and only reacts for vehicles ahead moving in the same direction as your vehicle. No distance information is provided for oncoming, slow-moving or stationary vehicles.
