Steering Assistance Upon Risk Of Run-Off 382; Steering Assistance Level In The Event Of A Run-Off Risk - Volvo XC90 TWIN ENGINE Owner's Manual

DRIVER SUPPORT
Steering assistance upon risk of
run-off
The subfunction's task is to help the driver
reduce the risk of the car accidentally leaving the
road by actively steering the car back onto the
road.
The function is active within the speed range
65-140 km/h (40-87 mph) on roads with clearly
visible lane markings/lines.
A camera scans the edges of the road and the
painted side markings. If the car is about to leave
the side of the road, the car is steered back onto
the road and if the steering intervention is not
enough to avoid run-off, the brakes are also acti-
vated.
However, the function does not intervene with
either steering assistance or brake intervention if
the direction indicators are used. And if the func-
tion detects that the driver is actively driving the
car, activation of the function will be delayed.
After automatic engagement, the driver display
indicates that this has occurred via a text mes-
sage:
•
Collision avoidance assistance
Automatic intervention
382
WARNING
•
The "Steering assistance at risk of lane
departure" subfunction is supplementary
driver support intended to improve driving
safety – it cannot handle all situations in
all traffic, weather and road conditions.
•
The function cannot detect barriers, rails
or similar obstacles at the side of the
road.
•
"Steering assistance at risk of lane
departure" is not a substitute for the driv-
er's attention and judgement. The driver
is always responsible for ensuring the car
is driven in a safe manner, at the appro-
priate speed, with an appropriate distance
to other vehicles, and in accordance with
current traffic rules and regulations.
