General Information

At speeds above approximately 40 mph (65 km/h), this function measures the distance to the vehicle ahead as time. If the distance falls below the warning threshold and remains there, the system will warn you of the hazard with the indicator light.

The display only appears if the Driver assistance display is selected in the trip computer and the adaptive cruise control is not actively controlling the vehicle.

• Detected vehicle driving ahead
• Use the markings to help you estimate the distance to an obstacle. Each marking represents approximately one second.
• Set warning threshold. Depending on the settings, the display will be colored from the bottom to the top.
• If the actual distance is smaller than the set distance, you will be informed about the danger.

Adjusting the Distance Warning

You can turn the distance warning on or off in the MMI, or adjust it to your preference. The settings depend on the vehicle equipment.

Messages

If a malfunction is displayed, the distance warning functions may be unavailable or limited.

A message indicating the cause and possible solution may appear. The weather conditions may be too poor or a sensor may be covered. Clean the area in front of the sensors and try to turn the system on again later.

If the malfunction remains, drive to an authorized Audi dealer or Audi Service Facility immediately to have the malfunction corrected.

Warning

Observe the safety precautions and note the limits of the assist systems, sensors, and cameras.

Tips

• The driver is always responsible for adhering to the regulations applicable in the country where the vehicle is being operated.
• You may briefly fall below the warning threshold when passing or quickly approaching a vehicle driving ahead. No warning is given in this situation.
• A warning is only given if you remain below the warning threshold for an extended period of time.
