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.
Even if the vehicle is not equipped with head-up display, a warning light will be displayed on the windshield and glow steadily if the time interval to the vehicle ahead is shorter than the set time interval.
Note
Visual warnings on the windshield may be difficult to notice in cases of strong sunlight, reflections, extreme light contrasts, or if the driver is wearing sunglasses or is not looking straight ahead.
Note
Distance Alert is deactivated while Adaptive Cruise Control (ACC2) or Pilot Assist is active.
Warning
Distance Alert only reacts of the time interval to the vehicle ahead is shorter than the preset value – vehicle speed is not affected.
