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
vehicles in some situations cannot be
detected, or they are detected later than
anticipated.
Dirty vehicles may be detected later than oth-
ers 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 or radar unit is obstructed,
City Safety may be unable to detect pedes-
trians, 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 camera and radar unit clear.
IMPORTANT
Maintenance of driver support components
must only be performed at a workshop –
an authorised Volvo workshop is recom-
mended.
17 The function is not available in all markets.
18 Electronic Stability Control
Driver intervention
Reversing
When your own car is reversing, City Safety is
temporarily deactivated.
Low speed
City Safety is not activated at very low speeds
- below 4 km/h (3 mph) - and the system
therefore 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 there-
fore delay a collision warning and intervention
in order to minimise unnecessary warnings.
DRIVER SUPPORT
Important warnings
WARNING
Driver supports only warn of obstacles
which their radar unit has detected –
hence a warning may not be given, or it
may be given with a certain delay.
Never wait for a warning or interven-
•
tion. Apply the brakes when the situa-
tion requires.
