Brake force display
The concept▷During normal brake application, the outer
brake lights light up.▷During heavy brake application, the inner
brake lights light up in addition.
Attentiveness assistant
The concept The system can detect increasing lack of alert‐
ness or fatigue of the driver during long, mo‐
notonous journeys, e.g., on highways. In this
situation, it is recommended that the driver
takes 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, e.g., steering behav‐
ior.▷Driving conditions, e.g., 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.
After a break, another recommendation to take
a break cannot be displayed until after approxi‐
mately 45 minutes.
System limits
The function may be limited in the following
situations, for instance, and will either output
an incorrect warning or no warning at all:
▷When the clock 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 surface is poor.▷In the event of strong side winds.Seite 113SafetyControls113
