General
Sensors detect the traffic situation in their de-
tection range.
The system issues a warning of a possible risk
of collision with vehicles at speeds above ap-
prox. 5 km/h/3 mph. The timing of these warn-
ings may vary depending on the current driving
situation.
The driver’s own driving behaviour is taken
into account in the responses of the system.
If an active driving style is detected, warnings
and brake interventions are output less fre-
quently.
Safety information
Follow the Safety Information in Chapter
“Front-collision warning”.
Display in the instrument cluster
A warning symbol is displayed when a collision
with a detected vehicle is imminent.

System limits
General
Follow the limits of the system in the chapter
“Front-collision warning”.
Detection range
The following situations may not be detected,
or only detected with a delay, for instance:
▷ Slow driving vehicle in front being ap-
proached at high speed.
▷ Vehicles suddenly cutting in or decelerating
heavily.
▷ Vehicles with unusual rear design.
▷ Two-wheeled vehicles ahead.
Upper speed limit
The system is temporarily disabled at speeds
over approx. 250 km/h, 155 mph. Once the
speed drops back below this threshold, the
system becomes responsive again according
to its settings.
Pedestrian Warning with city
braking function
Principle
The pedestrian warning with city braking func-
tion warns of the possible risk of collision with
pedestrians and cyclists at speeds that are
common in towns and cities and brakes auto-
matically if necessary.
If an accident cannot be avoided, the system
helps to reduce the collision speed.
