Limitations For Steering Assistance; Upon Risk Of Rear-End Collision - Volvo V90 Owner's Manual

DRIVER SUPPORT

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.

NOTE
The function uses the car's combined Camera
and Radar unit, which has certain general lim-
itations – see the sections "Limitations for
Camera Unit" and "Limitations for Radar Unit"
respectively.
In addition to the camera and radar unit, the func-
tion 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".
