ing to the traffic behind. This can reduce the risk
of a rear-end collision.

▷ During heavy brake application, the top brake
lights additionally light up.
Active Protection
General information
The Active Protection safety package consists of
systems that are independent of each other:
▷ Alertness assistant.
▷ PreCrash.
▷ PostCrash.
Alertness assistant
Concept
The system can detect decreasing alertness or
fatigue of the driver during long, monotonous
trips, for instance on highways. In this situation, 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 an accident. Make
sure that the driver is rested and alert. Adjust
driving style to traffic conditions.
Function
The system is switched on each time the engine
is started and cannot be switched off.
After travel has begun, the system monitors cer‐
tain aspects of the driver's behavior, so that de‐
creasing alertness or fatigue can be detected.
This procedure takes the following criteria into
account:
▷ Personal driving style, for instance steering
behavior.
▷ Driving conditions, for instance length of trip.
Starting at approximately 43 mph/70 km/h, the
system is active and can display a recommenda‐
tion to take a break.
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 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.
