Active Protection
General information
The Active Protection safety package consists
of systems that are independent of each other:
▷ Attentiveness assistant.
▷ PreCrash
▷ PostCrash
Attentiveness assistant
The concept
The system can detect increasing lack of alert‐
ness or fatigue of the driver during long, mo‐
notonous journeys, for example, on highways.
In this situation, it is recommended that the
driver take a break.
Note
Personal responsibility
The system cannot act as a substitute for
the personal assessment of one's physical
state and may not detect an increasing lack of
alertness or fatigue or may not detect it cor‐
rectly. Therefore, make sure that the driver is
rested and alert; otherwise, risks may be de‐
tected too late and an accident be caused as a
result.◀
Function
The system is activated each time the engine
is started and cannot be switched off.
After travel has begun, the system is trained
about the driver, so that increasing lack of
alertness or fatigue can be detected.
This procedure takes the following criteria into
account:
▷ Personal driving style, for example, steer‐
ing behavior.
▷ Driving conditions, for example, length of
trip.
Starting at approximately 43 mph/70 km/h, the
system is active and can display a recommen‐
dation to take a break.
Break recommendation
If the driver becomes increasingly less alert or
fatigued, a message is displayed in the Control
Display with the recommendation to take a
break.
A recommendation to take a break is displayed
only once during an uninterrupted trip.
