Limitations of City Safety
The City Safety function may have limitations in
certain situations.
Surroundings
Low objects
Low-hanging objects, e.g. a flag/pennant for pro-
jecting load, or accessories such as auxiliary
lamps and bull bars that are higher than the bon-
net limit the function.
Skidding
On slippery road surfaces the braking distance is
extended, which may reduce the capacity of City
Safety to avoid a collision. In such situations, the
anti-lock brakes and the stability control ESC
55
will give the best possible braking force with
maintained stability.
Oncoming light
The visual warning signal in the windscreen may
be difficult to notice in the event of strong sun-
light, reflections, when sunglasses are being
worn or if the driver is not looking straight ahead.
Heat
In the event of high passenger compartment
temperature caused by e.g. strong sunlight, the
visual warning signal in the windscreen may be
temporarily disengaged.
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 and replacement of City Safety
components must only be performed by a
workshop - an authorised Volvo workshop is
recommended.
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 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.
