Safety note
WARNING
The system may respond not at all, too
late, incorrectly, or without justification due to
limits of the system. There is a danger of acci‐
dent or damage to property. Observe the infor‐
mation on the system limits and intervene ac‐
tively if necessary.◀

▷ Pedestrians who are not detected as such
because of the viewing angle or outline.
▷ Pedestrians outside the detection range.
▷ Pedestrians less than approximately
80 cm, 32 in tall.
Functional restrictions
The function may be restricted or not available
in the following situations, for example:
▷ In thick fog, wet conditions or snow.
▷ On sharp bends.
▷ If vehicle stability control systems are de‐
activated, for example DSC OFF.

Lane Departure Warning
Principle
The Lane Departure Warning issues a warning
if the vehicle leaves its lane on a road with lane
markings.
General
Depending on the country version, the system
issues a warning at speeds between 55 km/h,
35 mph and 70 km/h, 45 mph.
When switching on the system below this
speed, a message is displayed in the instru‐
ment cluster.
Warnings are issued by means of a steering
wheel vibration. The timing of this warning may
vary depending on the current driving situa‐
tion.
The system does not issue a warning if the
driver indicates before leaving the driving lane.
Safety notes
WARNING
The system does not release you from
your personal responsibility to estimate the
course of the road and traffic situation. There
is a danger of accidents. Adapt your driving
style to the traffic conditions. Observe the traf‐
fic situation and intervene actively if the situa‐
tion warrants it. In the event of a warning, do
not move the steering wheel with unnecessary
force.◀
