Volvo V90 TWIN ENGINE Owner's Manual page 307

NOTE
The higher the speed the longer the cal-
•
culated distance in metres for a given
time interval.
Only use the time intervals permitted by
•
local traffic regulations.
The set time window is also used by the
•
adaptive cruise control and Pilot Assist
functions.
WARNING
Only use a time window that suits the
•
current traffic conditions.
The driver should be aware that short
•
time windows limit the amount of time
available to react and take action in an
unexpected traffic situation.

Limitations of Distance Warning
The Distance Warning function may have limita-
tions in certain situations.
WARNING
The Distance Warning function is supple-
•
mentary driver support intended to facili-
tate driving and make it safer – it cannot
handle all situations in all traffic, weather
and road conditions.
The vehicle's size may affect the ability to
•
detect, e.g. motorcycles, which could
mean that the warning lamp illuminates at
a shorter time window than set or that the
warning is temporarily absent.
Extremely high speeds can cause the
•
lamp to illuminate at a shorter time win-
dow than that set due to limitations in
radar unit range.
Distance Warning is not a substitute for
•
the driver's attention and judgement. The
driver is always responsible for ensuring
the car is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

NOTE
The function uses the car's radar unit, which
has some general limitations, see the section
"Limitations for radar unit".
