Audi Q3: Predictive control

Applies to: vehicles with adaptive cruise assist and predictive control

General information

With predictive control, efficiency assist adapts the speed set in the adaptive cruise control 1 fig. 97 based on detected speed limits and the upcoming route. Once the system no longer detects any relevant conditions ahead, adaptive cruise control will accelerate back up to the last speed set by the driver. After switching on the ignition, the availability of predictive control is indicated by a message when the adaptive cruise assist is first activated.

Incident symbols indicate the situation to which predictive control is reacting.

Requirements

  • Predictive control is switched on in the MMI.
  • The adaptive cruise assist must be actively regulating.
  • The system can only react to speed limits that are 15 mph (20 km/h) or higher.
  • The map content of the navigation system must be updated regularly in order for the system to work without restrictions.

Overriding control

The driver can override the predictive control based on the route ahead at any time by pressing the accelerator pedal. If the system changes the vehicle speed to adapt to speed limits, you can change the speed using the lever fig. 100.

Situation symbols

Depending on vehicle equipment, the following symbols may be shown. The symbols indicate the situation to which the predictive control is responding.

Some detail symbols will only be displayed in the Driver assistance display.

Messages

If and a message with Predictive control is displayed when there is a malfunction, the efficiency assist functions are unavailable or limited.

A message that indicates the cause and possible solution may appear with some displays. 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 authorized 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.
  • Pay attention to traffic and the area around your vehicle when predictive control is switched on. The driver is always responsible for assessing the traffic situation.
  • The system does not consider "right of way" rules and does not respond to traffic lights, so lack of driver attention in these situations can increase the risk of an accident.
  • The speed when driving through curves may be different from what you as a driver would do or may not be suitable for the weather and road conditions. If necessary, apply the brakes and reduce the selected speed to be maintained in the Adjustment to curves along route setting to reduce the risk of an accident.

Tips

  • Predictive control can exceed or drop below the maximum permitted speed. The driver is responsible for adhering to the permitted speed limit.
  • The traffic signs on the road always take priority over the display. The driver is always responsible for adhering to the regulations applicable in the country where the vehicle is being operated.
  • The system only detects traffic signs that specify a speed limit.
  • The display in the instrument cluster is based on the units of measurement used for speed in the country where the vehicle is being operated. As a result, a display of 50 in the instrument cluster can mean either mph or km/h, depending on the country.
  • If a speed limit is detected, the marking of the set speed limit will be adjusted even if the adaptive cruise assist is not actively regulating.
  • Control by the system depends on which adaptive cruise assist driving program is set or on the selected Audi drive select mode.
  • After switching on the ignition and first driving onto a freeway or similar road without a speed limit, the system will regulate the speed to 80 mph (130 km/h)1). Then the system adjusts to the last speed set by the driver.
  • There is no adaptation to speed limits when driving through highway interchanges and when driving on or off the expressway.
  • The system can fail to provide control or the control may be faulty if the values from the camera-based traffic sign recognition are incorrect or the navigation system map data is outdated.
  • Except for the road network, which is recorded in the navigation system's map information, certain functions may not be available.
  • When route guidance is switched on, the system adapts to the route provided by the navigation system. Driving without route guidance or leaving a route can result in faulty control.
