Fatigue alert
Principle
The Fatigue Alert system can detect when the
driver is less alert using various criteria.
The Fatigue Alert break recommendation func-
tion can detect driver fatigue, e.g., during long,
monotonous trips. If necessary, the system will
recommend that you take a break. A message
will appear on the control display.
The break recommendation can be adjusted
on the control display.
Safety information
Warning
The system cannot serve as a substitute for
the driver’s personal judgment in assessing
one's physical state. An increasing lack of
alertness or fatigue may not be detected or
not be detected in time. There is a risk of
accident. Make sure that the driver is rested
and alert. Adjust driving style to traffic condi-
tions.
Break recommendation
Function
After starting a journey, the break recommen-
dation function is trained to the driver, enabling
it to detect decreasing alertness or fatigue.
This process takes the following criteria into
account:
▷
Personal driving style, e.g., steering behav-
ior.
▷ Driving conditions, e.g., the time or duration
of the drive.
▷ Depending on vehicle equipment, informa-
tion from the Driver Attention Camera.
This function activates at speeds greater than
approx. 43 mph/70 km/h and can also display
a break recommendation.
Setting break recommendation
The Distraction Warning from the Fatigue Alert
system can be turned on or off or configured.
1. Go through the menu as follows via
iDrive: Apps menu / "Vehicle" / "Driving
settings" / "Driver Assistance" / "Safety and
warnings" / "Fatigue Alert".
2. Select the desired setting.
Display
If the driver becomes less alert or fatigued, the
Fatigue Alert system displays a message on
the control display, recommending the driver to
take a break.
During the display, various settings can be se-
lected.
The system is reset approx. 45 minutes after
parking the vehicle. A break recommendation
can only be displayed again after this time has
elapsed.
System limits
The Fatigue Alert system may be limited. If
the system is limited, either no warning may
be issued or an unwarranted warning may be
issued.
The break recommendation function may be
limited in the following situations:
▷
If the time is set incorrectly.
▷ At a predominantly driven speed below ap-
prox. 43 mph/70 km/h.
▷ With a sporty driving style such as during
rapid acceleration or when cornering fast.
▷ In active driving situations such as when
changing lanes frequently.
▷ When the road condition is poor.
▷ In the event of strong side winds.
