Attentiveness assistant
The system can detect decreasing alertness or
fatigue of the driver during long, monotonous
trips, e.g., on highways. In this situation, it is
recommended that the driver takes a break.
Safety information
The system does not release from the
personal responsibility to correctly assess
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 acci‐
dent. Make sure that the driver is rested and
alert. Adjust the driving style to the traffic con‐
The system is activated each time the engine

After travel has begun, the system monitors
certain aspects of the driver's behavior, so that

This procedure takes the following criteria into
Personal driving style, e.g., steering behav‐
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 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, e.g., and will either output an incor‐
rect 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.
The system is reset approx. 45 minutes after
parking the vehicle, e.g., in the case of a break
during longer trips on highways.
Post Crash — iBrake
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.
Harder vehicle braking
It can be necessary to bring the vehicle in cer‐
tain situations to a halt quicker.
Here, a higher braking pressure must be gen‐
erated for a short period when pressing the
brake pedal than during automatic braking.
This interrupts automatic braking.
Interrupting automatic braking
It can be necessary to interrupt automatic
braking in certain situations, for example for an
evasive maneuver.
