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.

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.
WARNING
Warnings and brake interventions
•
could be implemented late or not at all
if a traffic situation or external influ-
ences mean that the camera and radar
unit cannot detect pedestrians,
cyclists, large animals or vehicles cor-
rectly.
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 interventions as long as the
relative speed is below 50 km/h
(30 mph). For stationary or slow-mov-
ing vehicles, warnings and brake inter-
ventions are effective at vehicle speeds
up to 70 km/h (43 mph). Speed reduc-
tion 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 inter-
vention for large animals is less effec-
tive at lower speeds.
Warnings for stationary or slow-mov-
•
ing vehicles as well as large animals
