Safety information
WARNING
The system can react incorrectly or not
at all due to the system limits. There is a risk of
accidents or risk of property damage. Observe

E.g., the following situations may not be de‐
tected:

▷ Pedestrians having a body size less than
32 in/80 cm.

not be available in the following situations:
▷ In heavy fog, rain, sprayed water or snow‐
fall.
▷ In tight curves.
▷ If the driving stability control systems are
deactivated, for instance DSC OFF.
▷ If the field of view of the camera or the
windshield are dirty or covered.
▷ Up to 10 seconds after the start of the en‐
gine via the Start/Stop button.

Lane departure warning
The concept
Starting at a specific speed, this system alerts
you when the vehicle on streets with lane
markings is about to leave the lane. This
speed, depending on the country version, is
between 35 mph/55 km/h and
45 mph/70 km/h.
When switching on the system below this
speed, a message is displayed in the instru‐
ment cluster.
The steering wheel begins vibrating gently in
the event of warnings. The time of the warning
may vary depending on the current driving sit‐
uation.
The system does not provide a warning if the
turn signal is set before leaving the lane.
Safety information
WARNING
The system does not release the driver
from the personal responsibility to correctly
assess route and traffic situation. There is a
risk of an accident. Adjust the driving style to
the traffic conditions. Watch traffic closely and
actively intervene in the respective situations.
In the event of a warning, do not unnecessarily
jerk the steering wheel.◀
