Limitations of City Safety

The City Safety 19 function may have limita-
tions in certain situations.
Surroundings
Low objects
Low-hanging objects, e.g. a flag/pennant for
projecting load, or accessories such as auxili-
ary lamps and bull bars that are higher than
the bonnet 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 situa-
tions, the anti-lock brakes and the stability
20
control ESC are designed to give the best
possible braking force with maintained stabil-
ity.
Oncoming light
The visual warning signal in the windscreen
may be difficult to notice in the event of strong
sunlight, 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.
19 The function is not available in all markets.
20 Electronic Stability Control

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.
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.
