Limitations for steering assistance
upon risk of rear-end collision
In certain situations the function may have lim-
ited functionality and fail to intervene in the fol-
lowing cases, for example:
•
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-exis-
tent 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 overheat-
ing (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 func-
tion.
