Limitations Of Distance Warning - Volvo XC 90 Owner's Manual

DRIVER SUPPORT

Limitations of Distance Warning*

The Distance warning (Distance Alert) function
may have limitations in certain situations.
NOTE
Strong sunlight, reflections or strong varia-
tions in light intensity, as well as wearing sun-
glasses, could mean that the warning light in
the windscreen cannot be seen.
Poor weather or winding roads could affect
the radar unit's capacity to detect vehicles in
front.
The size of other vehicles could also affect
detection capacity, e.g. motorcycles. This
could mean that the warning lamp illuminates
at a shorter distance than the setting or that
the warning is temporarily absent.
Extremely high speeds can also cause the
lamp to illuminate at a shorter distance than
that set due to limitations in sensor range.
NOTE
The function uses the car's radar unit, which
has some general limitations, see the "Limita-
tions for radar unit" section.

City Safety
City Safety uses visual and acoustic signals to
alert the driver of any pedestrians, cyclists and
vehicles that appear - the car brakes automati-
cally unless the driver himself acts within a rea-
sonable time.
Location of the radar unit.
City Safety can prevent a collision or reduce colli-
sion speed.
City Safety is an aid to assist a driver who is at
risk of colliding with a pedestrian, cyclist or vehi-
cle.
The City Safety function can help the driver to
avoid a collision when driving in queues, e.g.
when changes in the traffic ahead, combined with
a lapse in attention, could lead to an incident.
