Fatigue alert
Principle
The system can detect decreasing alertness or
fatigue of the driver during long, monotonous
trips, for instance on highways. In this situa-
tion, it is recommended that the driver takes a
break.
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 ac-
cident. Make sure that the driver is rested
and alert. Adjust driving style to traffic condi-
tions.
Function
The system is switched on each time the en-
gine is started and cannot be switched off.
After start of the trip, the system monitors cer-
tain aspects of the driver's behavior, so that
decreasing alertness or fatigue can be de-
tected.
This procedure takes the following criteria into
account:
▷ Personal driving style, for instance steering
behavior.
▷ Driving conditions, for instance time, length
of trip.
Starting at approximately 43 mph/70 km/h, the
system is active and can display a break rec-
ommendation.
Break recommendation
If the driver becomes less alert or fatigued, a
message is displayed in the Control Display
with the recommendation to take a break.
A break recommendation is displayed only
once during an uninterrupted trip.
After a break, another break recommendation
cannot be displayed until after approximately
45 minutes.
System limits
The function may be limited in the following
situations and may issue an incorrect warning
or no warning at all:
▷ When the time is set incorrectly.
▷ When the vehicle speed is mainly below
about 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.
The system is reset approx. 45 minutes after
parking the vehicle, for instance in the case of
a break during longer trips on highways.
PostCrash – iBrake
Principle
In the event of an accident, the system can
bring the vehicle to a halt automatically without
intervention by the driver in certain situations.
This can reduce the risk of a further collision
and the consequences thereof.
