The camera and radar unit's field of view
The camera's field of vision is limited, which is
why pedestrians, large animals, cyclists and vehi-
cles in some situations cannot be detected, or
they are detected later than anticipated.
Dirty vehicles may be detected later than others
and if it is dark, motorcycles may be detected late
or not at all.
If a text message in the driver display indicates
that the camera and radar unit is obstructed, City
Safety may be unable to detect pedestrians, large
animals, cyclists, vehicles or road lines ahead of
the car. This means that the functionality of City
Safety may be reduced.
However, an error message is not shown in all
situations where the windscreen sensors are
obstructed. The driver must therefore take care to
keep the area of windscreen in front of the cam-
era and radar unit clear.
IMPORTANT
Maintenance of driver support components
may only be performed at a workshop
Driver intervention
Reversing
When your own car is reversing, City Safety is
temporarily deactivated.
An authorised Volvo workshop is recommended.

Low speed
City Safety is not activated at very low speeds -
below 4 km/h (3 mph) - and the system there-
fore does not intervene in situations where your
car is approaching a vehicle ahead very slowly,
e.g. when parking.
Active driver
Driver commands are always prioritised, which is
why City Safety does not intervene or postpone
warning/intervention in situations where the
driver is steering and accelerating in a decisive
manner, even if a collision is unavoidable.
Active and aware driving behaviour can therefore
delay a collision warning and intervention in order
to minimise unnecessary warnings.

WARNING
Warnings and brake interventions could
•
be implemented late or not at all if a traf-
fic situation or external influences mean
that the camera and radar unit cannot
detect pedestrians, cyclists, large animals
or vehicles correctly.
For vehicles to be detected at night, their
•
headlamps and rear lamp cluster must be
switched on and shining clearly.
The camera and radar unit has a limited
•
range for pedestrians and cyclists. The
system can provide effective warnings
and brake interventions as long as the
relative speed is below 50 km/h
(30 mph). For stationary or slow-moving
vehicles, warnings and brake interven-
tions are effective at vehicle speeds up to
70 km/h (43 mph). Speed reduction for
large animals is less than 15 km/h
(9 mph) and can be achieved at vehicle
speeds above 70 km/h (43 mph). The
warning and brake intervention for large
animals is less effective at lower speeds.
