System limits
Be alert
Due to system limitations, warnings may
be not be issued at all, or may be issued late or
improperly. Therefore, always be alert and
ready to intervene; otherwise, there is the dan‐
ger of an accident occurring.◀
Detection range
The system's detection capabilities are limited.
This may result in the warning not being is‐
sued or being issued late.
For example, the following situations may not
be detected:
▷ Slow moving vehicles when you approach
them at high speed.
▷ Vehicles that suddenly swerve in front of
you or sharply decelerating vehicles.
▷ Vehicles with an unusual rear appearance.
▷ Two-wheeled vehicles ahead of you.
▷ Pedestrians.
Functional limitations
The system may not be fully functional in the
following situations:
▷ In heavy fog, rain, sprayed water or snow‐
fall.
▷ In tight curves.
▷ If the driving stability control systems are
limited or deactivated, for example, DSC
OFF.
▷ If the camera in the mirror or the radar sen‐
sor is dirty or obscured.
▷ During calibration of the camera immedi‐
ately after vehicle shipment.
▷ If there is constant dimming because of
oncoming light, for example, from the sun
low in the sky.
Prewarning sensitivity
Depending on the set prewarning time, this
may result in increased false warnings.
Pedestrian warning
Depending on how the vehicle is equipped, the
function warns of an imminent collision with
pedestrians during daytime or nighttime.
The function is subdivided into the following
systems:
▷ During daytime: Pedestrian warning with
city braking function, refer to page
118
▷ At night: Night vision, refer to page 120
