of damage to property. Actively intervene as
warranted. Refer to the information in this Own‐
er's Manual regarding the scope of the sys‐
tem's operation and limitations.
Detection range
The system's detection capability is limited.
Only objects that are detected by the system are
taken into account.
Thus, a system reaction might not come or
might come late.
The following situations may not be detected, for
example:
▷ Slow moving vehicles when you approach
them at high speed.
▷ Vehicles that suddenly swerve in front of you,
or strongly decelerating vehicles.
▷ Vehicles with an unusual rear view.
▷ Two-wheeled vehicles ahead of you.

▷ If the driving stability control systems are lim‐
ited or deactivated, for instance DSC OFF.

Intersection collision
warning
Principle
The system may prevent some accidents with
cross traffic at intersections and junctions. In the
event of an accident, the system may reduce im‐
pact speed.
The system sounds a warning in the city speed
range before an imminent collision and activates
brakes independently, if needed.
General information
Sensors detect the traffic situation.
Vehicles that cross your driving direction can be
detected by the system as soon as these vehi‐
cles enter into the detection range of the system.
At intersections and junctions, a warning is is‐
sued when a danger of collision with crossing
traffic is detected.
The system issues a two-phase warning of a
possible risk of collision with vehicles at speeds
above approx. 6 mph/10 km/h. The timing of
warnings may vary with the current driving situa‐
tion.
The Driver Attention Camera in the instrument
cluster captures the driver's field of vision. Addi‐
tionally, the system checks for visual impair‐
ments. Field of vision and visibility also affect the
timing of the warnings.
