Distance Warning symbol on the windscreen with head-up display.
In cars equipped with head-up display, a symbol is shown on the windscreen for as long as the time interval to the vehicle ahead is shorter than the preset value. However, this assumes that the Show Driver Support function is activated via the settings in the car's menu system.
Distance warning is active at speeds above 30 km/h (20 mph) and only reacts to the vehicle ahead travelling in the same direction. No distance information is provided for oncoming, slow or stationary vehicles.
Warning light for Distance Warning on the windscreen.
Even if the car is not equipped with a head-up display, a warning light appears on the windscreen and shines steadily if the time interval to the vehicle in front is shorter than a preset value.
Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if the driver is not looking straight ahead may make the visual warning signal in the windscreen difficult to recognise.
Distance warning is deactivated during the time the adaptive cruise control (ACCAdaptive Cruise Control) or Pilot Assist is active.
Distance warning only reacts if the time window to the vehicle ahead is shorter than the preset value – the speed of the driver's vehicle is not affected.
