Lane departure warning
Concept
The lane departure warning alerts when the vehi‐
cle is about to run off the road or exit the lane.
General information
This camera-based system warns starting at a
minimum speed.
The minimum speed is country-specific and is
displayed in the menu for the intelligent Safety
systems.
Warnings are issued by means of a steering
wheel vibration. The severity of the steering
wheel vibration can be adjusted.
The system does not provide a warning if the
turn signal is set before leaving the lane.
If in the speed range up to 130 mph/210 km/h a
lane marking is crossed, the system intervenes
with a brief active steering intervention in addi‐
tion to vibrating. The system thus helps keep the
vehicle in the lane.
Safety information
Warning
The system cannot serve as a substitute for the
driver’s personal judgment in assessing road
and traffic safety. There is a risk of accident.
Adjust driving style to traffic conditions. Watch
traffic closely and actively intervene where ap‐
propriate. Do not jerk the steering wheel in re‐
sponse to a warning.
Warning
Indicators and warnings cannot serve as a sub‐
stitute for the driver’s personal judgment. Due
to its limits, the system may not issue warnings
or reactions, or these may be issued late or in a
manner that is not consistent with their normal
use. There is a risk of accident. Adjust driving
style to traffic conditions. Watch traffic closely
and actively intervene where appropriate.
Functional requirements
The camera must detect the lane markings for
the lane departure warning to be active.
