Mercedes-Benz Actros, Operating Instructions Manual

#
Always steer the vehicle paying atten‐
tion to the traffic situation.
If, when driving with the Lane Keeping function
activated, the conditions for active steering by
the function are no longer fulfilled, for example if
no lane markings are detected or present, the
system changes to passive mode automatically.
This is signalled to the driver by means of a warn‐
ing tone and a red event window in the instru‐
ment cluster. When the conditions are met again,
the system changes back to active mode auto‐
matically.
Status display
The driver is shown the current status of the sys‐
tem by the Ø indicator lamp in the instrument
cluster.
Example: Lane Keeping status display
Status display 1 differentiates between the fol‐
lowing system statuses:
R
No display - function switched off
R
Flashing grey - the system is malfunctioning.
The function has been deactivated automati‐
cally.
-
If the problem continues after an ignition
cycle, have the system checked at a quali‐
fied specialist workshop.
R
Lit up grey - the function is switched on but
passive
-
No lane markings detected
-
Lane too narrow or too wide
-
Bend too tight
-
Change of lane detected
-

-
Driver intervention detected
-

ity
R
Lit up blue - the function is switched on and
active
Active Drive Assist is deactivated automatically if
it malfunctions. The instrument cluster then dis‐
plays the red event window Take control of steer-
ing immediately .
Hands On
The function requires that the driver always has
their hands on the steering wheel so that they
can correct the course or intervene to correct the
lane at any time.
If the driver is inactive for a period of 15 seconds,
a yellow event window with the Ø warning
symbol is shown in the instrument cluster.
After 30 seconds of inactivity, a red event win‐
dow with the Ø warning symbol is shown and
a warning tone sounds which increases in inten‐
sity with time.
After 60 seconds of inactivity, an aggressive
warning tone sounds and the Lane Keeping func‐
tion changes to passive mode. The Ø status
display in the instrument cluster is then shown in
grey.
The warning tone sounds until the driver puts
their hands back on the steering wheel (at least
five seconds).
If Lane Keeping function is switched to passive
three times within one ignition cycle due to driver
inactivity, it is deactivated. The instrument cluster
then shows the yellow Highway-Pilot unavailable
event window. If you scroll down using the steer‐
ing wheel buttons, the Observe notes on taking
control of steering Act. Drive Assist deact. for
ignition sequence text is displayed.
If none of the described visual or acoustic warn‐
ings are issued despite the driver remaining inac‐
tive, the system must be checked at a qualified
specialist workshop. In this case, pay particular
attention and keep your hands on the steering
wheel at all times.
Driver intervention
System steering interventions can always be
overridden by the driver.
In the event of abrupt steering interventions by
the driver, e.g. swerving manoeuvres or operating
the turn signal indicator, the function switches to
passive mode for a brief period.
Setting the target lane position
The driver has the option of moving the target
lane position, to which the system steers the
vehicle, by 5% of the lane width from the centre
of the lane to the left or right.
