Limitations of steering assistance during collision risks from oncoming traffic

Updated 2020-03-19

The function may have limited functionality in certain situations and not intervene, e.g.:

for smaller vehicles such as motorcycles
on roads that do not have clear lane markings
if more than half of your vehicle has moved 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").

Functionality may also be reduced in other situations, such as:

road work
winter driving conditions
narrow roads
poor road surfaces
a very sporty driving style
bad weather with reduced visibility.

In these demanding driving conditions, the function may not be able to properly assist the driver. In these situations, it is recommended that it is turned off.

Note

The function uses the vehicle's combined camera and radar unit, which has certain general limitations; see sections "Camera limitations" and "Radar sensor limitations".
