Applies to vehicles: with Audi adaptive cruise control
To display the current distance setting, briefly press the rocker switch Fig. 1.
To increase or reduce the distance by one level, briefly press the rocker switch to the right or left again. The distance between the two vehicles will be shown on the instrument cluster display.
When you draw closer to a vehicle detected in front, the adaptive cruise control matches your speed to that vehicle by applying the brakes, and then maintains a constant distance (which you can adjust in the settings). If the vehicle in front accelerates, the adaptive cruise control will also accelerate, up to the target speed you have specified.
The higher the speed, the higher the distance in metres WARNING!. We recommend you to use the setting: distance 3. You will then be following the general recommendations of automobile clubs, traffic authorities, etc.
The actual distance maintained by the adaptive cruise control can be longer or shorter, depending on the traffic situation, your current speed, and the driving style of the driver in front.
distance 1: This setting is equivalent to a distance of 28 metres at a speed of 100 km/h (time-based distance of 1 second).
distance 2: This setting is equivalent to a distance of 36 metres at a speed of 100 km/h (time-based distance of 1.3 seconds).
distance 3: This setting is equivalent to a distance of 50 metres at a speed of 100 km/h (time-based distance of 1.8 seconds).
distance 4: This setting is equivalent to a distance of 67 metres at a speed of 100 km/h (time-based distance of 2.4 seconds).
WARNING!
When setting the distance, the driver is responsible for adhering to the locally applicable laws and regulations.
Note
Distance 3 is set automatically each time the ignition is switched on. If you would prefer to have a different distance as the default setting, you can have the adaptive cruise control menu extended/activated by a qualified workshop.
