DRIVER SUPPORT

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 traffic situa-
tion or external influences mean that the cam-
era 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 interven-
tions 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.
Warnings for stationary or slow-moving vehi-
cles and large animals could be disengaged
due to darkness or poor visibility.
Warnings and brake interventions for pedes-
trians and cyclists are deactivated at vehicle
speeds exceeding 70 km/h (43 mph).
Do not place, stick or mount anything on the
outside or inside of the windscreen in front of
or around the camera and radar unit — this
can interfere with camera-dependent func-
tions.
Objects, snow, ice or dirt in the area of the
camera sensor may reduce its function, fully
deactivate it or give incorrect function
response.
NOTE
The function uses the car's camera unit,
which has some general limitations, see the
"Limitations for camera unit" section.
NOTE
The function uses the car's radar unit, which
has some general limitations, see the "Limita-
tions for radar unit" section.
