dicated side.
2
White line: road lane marking detected.

dashed lane markings.
With some equipment levels, a display is also
shown on the Head-up Display → page 21.
The following indicator lamps light up, de-
pending on the driving situation:
System is active and ready to per-
form control intervention.
System intervention (corrective
steering intervention).
If no warning lamp lights up, the system is
not ready to intervene on either side (passive
system status) or is switched off.
If the comfort drive function (Travel
Assist) is actively performing a control
operation, there is no steering intervention
and the lane keeping system is not displayed.
Driver intervention prompt
If there is no steering activity, the system
prompts you to drive in the middle of the
lane by means of acoustic warnings and
a display on the instrument cluster.
If you do not react, the system will switch to
passive state.
Depending on the vehicle equipment, Emer-
gency Assist will be activated if Emergency
Assist is switched on in the Infotainment sys-
tem.
Independently of steering activity, you will be
additionally requested to drive in the middle
of the lane again with a display on the instru-
ment cluster display and with acoustic warn-
ings if the corrective steering intervention
takes place for an extended time.
Steering wheel vibration
The following situations can lead to vibration
of the steering wheel:
— The system can no longer detect a lane
during a major steering intervention.
You can also select the option
Vibration
or
Steer-
ing wheel vibration
in the Assist systems menu of
the Infotainment system. In this case, the
steering wheel will vibrate if the vehicle
drives over a detected road lane marking
when the lane keeping system is active.
