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. This function recommends
taking a break as necessary. 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, injury, and property damage. Make
sure that the driver is rested and alert. Adjust
driving style to traffic conditions.
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:
Apps menu / "Vehicle" / "Driving
settings" / "Driver Assistance" / "Safety and
warnings" / "Fatigue Alert".
2. Select the desired setting.
Despite this function being off, some driver as-
sistance systems may issue break recommen-
dations.
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.
