Ready for warning: The indicator lamp lights up when the system is fully functional. You will be warned if you are about to cross the lane markings detected by the system.
Not ready for warning: The indicator lamp lights up when the system is switched on. However, you will not be warned if you cross the lane markings. This can have the following causes:- There is only one or no lane marking.
- The system cannot detect the lane markings (e.g. due to snow, dirt, wet conditions or adverse light).
- There are more than two lane markings in the lane you are driving in (e.g. in roadwork sections).
- The vehicle's speed is below 65 km/h, the speed at which the lane assist system is activated.
- The lane is narrower than 2.5 m or wider than 5 m.
- The bend is too tight.
Driver messages in the instrument cluster display
Should the lane assist be deactivated automatically, the indicator lamp in the instrument cluster display will go out and one of the following messages will appear:
Audi lane assist not available: currently no sensor vision
This message is displayed when the camera is no longer functional after the system has continuously failed to detect the lane markings. This can have the following causes:
- The outside of the camera window Fig. 2 is dirty or frosted. Remove dirt or ice from this area of the windscreen.
- The inside of the camera window is misted up. In this case, please wait for the camera window to demist before switching on the lane assist system again.
- Due to the conditions (e.g. snow-covered road) the system has not been able to detect the lane markings for a long period. Do not switch the lane assist system on again before the lane markings are discernible.
Audi lane assist currently not available
A temporary error is preventing the lane assist system from fully functioning. Try switching on the lane assist system again later.
