Limitations for steering assistance upon risk of head-on collision

Updated 19/03/2020

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.

Note

The function uses the car's combined Camera and Radar unit, which has certain general limitations – see the sections "Limitations for Camera Unit" and "Limitations for Radar Unit" respectively.
