Road Sign Information (Rsi)* Limitations - Volvo XC 90 Owner's Manual

Sensus Navigation
The Sensus Navigation system provides speed
limit-related information:
•
If a speed limit changes indirectly such as
when a sign indicating the end of an
expressway, highway or other limited access
road is detected.
•
If a previously detected speed limit is no
longer considered to apply and no new
speed limit signs have been detected.
Signs for school zones or children at
play
If warning signs for a school
zone or children at play are
included in the Sensus
Navigation system's map data-
base, this symbol will appear in
the instrument panel when a
sign of this type has been
detected.
