Limitations for steering assistance upon risk of head-on collision

In certain situations the function may have limited functionality and fail to intervene in the following cases, for example:
  • for small vehicles, such as motorcycles
  • on roads where the lane does not have clear lane markings
  • if the majority of the car has steered into the adjacent lane
  • 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.


The function uses the car's camera unit, which has some general limitations, see the "Limitations for camera unit" section.


The function uses the car's radar unit, which has some general limitations, see the section "Limitations for radar unit".
