Warning function
If you leave the lane
If you leave the lane and if a lane boundary
has been detected, the steering wheel vibrates
in accordance with the steering wheel vibration
setting.
In addition, the indicator light flashes
green.
When the turn signal is switched on in the cor-
responding direction before changing the lane,
a warning is not issued.
Steering intervention
Depending on vehicle equipment and national-
market version: The Lane Departure Warning
system may intervene with an active steer-
ing intervention in addition to vibration if
you cross a lane marking at speeds up to
130 mph/210 km/h. The system supports the
driver in keeping the vehicle within the lane.
The steering intervention can be noticed on
the steering wheel and can be manually over-
ridden at any time.
When steering intervention is active,
the indicator light flashes green.
For instance, the steering intervention will be
suppressed in the following situations:
▷ With hard accelerating or braking.
▷ When flashing.
▷ With hazard warning system switched on.
▷ In driving situation with high driving dynam-
ics.
▷ While Dynamic Stability Control regulates
driving stability.
▷ While Dynamic Stability Control is limited.
▷ Immediately following a steering interven-
tion by the vehicle systems.

Warning signal
Depending on national-market version: An
acoustic warning will sound if the Lane Depar-
ture Warning system performs multiple active
steering interventions within 3 minutes and
the driver does not operate the steering wheel
themselves during the steering intervention(s).
A short warning signal will sound at the second
steering intervention. Beginning with the third
steering intervention, a continuous warning will
sound.
In addition, a Check Control message is dis-
played.
The warning tone and Check Control message
advise the driver to pay closer attention to their
lane.
The extended warning tone stops when the
steering wheel is moved manually.
With trailer towing
No steering intervention is performed if the
Lane Departure Warning is activated and the
trailer power socket is occupied or trailer tow-
ing is activated, e.g., when using a trailer.
If using a rear carrier, e.g., rear bicycle rack, on
the trailer hitch, this restriction does not apply
when trailer towing is activated on the control
display.
Additional information:

The warning or active steering intervention will
be canceled in the following situations, for ex-
ample:
▷ Automatically after a few seconds.
▷ When returning to your own lane.
▷ With hard accelerating or braking.
