CONTROLS
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
instance:
▷ 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.
Upper speed limit
If the vehicle speed exceeds approx.
155 mph/250 km/h, the system is deactivated
temporarily. When the vehicle slows down to be‐
low this speed, the system is reactivated.
System limits of the sensors
Additional information:
▷ Cameras, refer to page 35.
▷ Radar sensors, refer to page 36.
Functional limitations
The system may be limited in the following situa‐
tions:

Safety
Online Edition for Part no. 01405A37CC6 - VI/21
▷ In tight curves.
▷ If the driving stability control systems are lim‐
ited or deactivated, for instance DSC OFF.
▷ Up to 10 seconds after the start of the engine
via the Start/Stop button.
Warning sensitivity
The more sensitive the warning settings are, for
example the warning time, the more warnings are
displayed. Therefore, there may also be an ex‐
cess of premature or unjustified warnings and re‐
actions.
Evasion Assistant
Principle
The Evasion Assistant supports the driver in
making evasive maneuvers in certain situations,
such as when obstacles or persons suddenly ap‐
pear.
General information
The system issues a warning and intervenes to
support the driver if a lateral evasive maneuver is
possible. Sensors monitor and detect the clear‐
ance around the vehicle. If the system identifies
space alongside the vehicle, it supports an eva‐
sive maneuver begun by the driver by safely pro‐
viding targeted supporting steering movements.
Safety information
Warning
The system cannot serve as a substitute for the
driver's personal judgment in assessing visibility
and traffic situation. There is a risk of accident.
Adjust driving style to traffic conditions. Watch
traffic closely and actively intervene where ap‐
propriate.
