Driver intervention
Backing up
City Safety is temporarily deactivated when
the vehicle is backing up.
Low speed
City Safety is not activated at very low speeds
under 4 km/h (3 mph). The system will there-
fore not intervene in situations in which your
vehicle is approaching another vehicle very
slowly, such as when parking.
Active driver
Action by the driver always has priority. City
Safety will therefore not react or will react at a
later stage with a warning or intervention in
situations in which the driver is clearly steering
and operating the accelerator pedal, even if a
collision is unavoidable.
An active and aware driving style may there-
fore delay collision warnings and intervention
in order to minimize unnecessary warnings.
Other limitations
WARNING
The driver support system only issues a
warning for obstacles detected by its radar
sensor – thus, a warning may come after a
delay or not at all.
Never wait for a warning or assistance.
•
Apply the brakes when necessary.
WARNING
Warnings and brake interventions can
•
be triggered late or not at all if the traf-
fic situation or external influences pre-
vent the camera and radar unit from
properly detecting pedestrians,
cyclists, large animals or vehicles
ahead of the vehicle.
To be able to detect vehicles at night,
•
its front and rear lights must work and
illuminate clearly.
The camera and radar unit have a lim-
•
ited range for pedestrians and cyclists
– the system can provide effective
warnings and brake interventions if the
relative speed is lower than 50 km/h
(30 mph). For stationary or slow-mov-
ing vehicles, warnings and brake inter-
ventions are effective at vehicle speeds
of 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 over 70 km/h
(43 mph). At lower speeds, the warn-
ing and brake intervention for large ani-
mals is less effective.
Warnings for stationary or slow-mov-
•
ing vehicles and large animals can be
disengaged due to darkness or poor
visibility.
DRIVER SUPPORT
Warnings and brake interventions for
•
pedestrians and cyclists are disen-
gaged at vehicle speeds over 80 km/h
(50 mph).
Do not place, affix or mount anything
•
on the inside or outside of the wind-
shield, or in front of or around the cam-
era and radar unit – this could disrupt
camera-based functions.
Objects, snow, ice or dirt in the area of
•
the camera sensor can reduce the
function, disengage it completely or
give an improper function response.
