System limits
Information
WARNING
The system can react incorrectly or not
at all due to the system limits. There is risk of
accidents or risk of property damage. Observe
the system limits and actively interfere if
needed.◀
Detection range
The system's detection potential is limited.
Thus a system reaction might not come or
might come late.
E. g. the following situations may not be de‐
tected:
▷ 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.
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, depending on the vehicle equipment
version, the field of view of the camera in
the mirror or the radar sensor is dirty or ob‐
scured.
▷ Up to 10 seconds after the start of the en‐
gine, via the Start/Stop button.
▷ During calibration of the camera immedi‐
ately after vehicle delivery.

▷ If there are constant blinding effects be‐
cause of oncoming light, e. g., from the sun
low in the sky.
Warning sensitivity
The more sensitive the warning settings are,
for example the warning time, the more warn‐
ings are displayed. However, there may also be
an excess of false warnings.
Collision warning with
braking function
The concept
The system can help prevent accidents. If an
accident cannot be prevented, the system will
help reduce the collision speed.
The system sounds a warning before an immi‐
nent collision and actuates brakes independ‐
ently if needed.
The automatic braking intervention is executed
with limited braking force and for a brief period
only.
If the vehicle is equipped with Active Cruise
Control with Stop & Go, the front-end collision
warning is controlled via the cruise control ra‐
dar sensor.
The front-end collision warning is available
even if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally, the collision warning and braking
are delayed in order to avoid false system re‐
actions.
General information
The system issues a two-phase warning of a
possible danger of collision with vehicles at
speeds above approx. 3 mph/5 km/h. Time of
warnings may vary with the current driving sit‐
uation.
