- if the majority of the car has steered into the adjacent lane
- on roads/in lanes with unclear or non-existent lane markings
- outside the speed range 60-140 km/h (37-87 mph)

Other demanding situations can include:
- road works
- winter road conditions
- narrow roads
- poor road surface
- a very “sporty” driving style
- poor weather with reduced visibility.
In these demanding situations, the function may have difficulty helping the driver correctly. In such cases it is recommended to switch off this function.
This function uses the car's camera and radar units, which have certain general limitations.
