Head-up display for Distance Alert[1]
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.
For this to be possible, however, the Show Driver Support function must be activated under Settings in the center display's menus (see "Head-up display" for instructions).
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
