DRIVER SUPPORT
||
WARNING
The function is supplementary driver sup-
•
port intended to facilitate driving and
make it safer – it cannot handle all situa-
tions in all traffic, weather and road condi-
tions.
The driver is advised to read all sections
•
in the Owner's Manual that relate to this
function to learn about factors such as its
limitations and what the driver should be
aware of before using the system.
Driver support functions are not a substi-
•
tute for the driver's attention and judge-
ment. The driver is always responsible for
ensuring the car is driven in a safe man-
ner, at the appropriate speed, with an
appropriate distance to other vehicles,
and in accordance with current traffic
rules and regulations.

Limitations of City Safety
64
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
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.
65
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
