The warning distance setting should there-
fore only be used in exceptional cases, such as
when a more dynamic driving style is preferred.
WARNING
• No automatic system can guarantee
100% correct function in all situations.
You should therefore never test use of
City Safety in the direction of people, ani-
mals or vehicles – this could lead to
severe damage, serious personal injury or
even death.

City Safety warns the driver if there is a
risk of collision, but the function cannot
reduce the driver's reaction time.

City Safety can detect most vehicles that are sta-
tionary or are moving in the same direction as
your vehicle. In some cases, it can also detect
oncoming vehicles and crossing traffic.
For City Safety to be able to detect a vehicle in
the dark, its headlights and taillights must be on
and clearly visible.
Cyclists
Optimal examples of what City Safety would interpret to
be a cyclist: clear body and bicycle shapes.
For optimal performance, the system's function
for cyclist detection needs the clearest possible
information about the contours of the bicycle and
of the cyclist's head, arm, shoulders, legs, torso
