- for small vehicles, such as motorcycles
- 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)
- when the power steering works at reduced power - e.g. during cooling due to overheating (see section "Speed-dependent steering force").
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.
Note
The function uses the car's camera unit, which has some general limitations, see the "Limitations for camera unit" section.
Note
The function uses the car's radar unit, which has some general limitations, see the section "Limitations for radar unit".
In addition to the camera and radar unit, the function uses the car's rear-facing radar, which has certain general imitations that a driver should be aware of - see supplementary information in the section "Limitations for BLIS".
