Safety information
Warning
The system cannot serve as a substitute
for the driver’s personal judgment in as-
sessing one's physical state. An increasing
lack of alertness or fatigue may not be de-
tected or not be detected in time. There is
a risk of 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 en-
gine is started and cannot be switched off.
After travel has begun, the system monitors
certain aspects of the driver's behavior, so
that decreasing 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 time,
length of trip.
Starting at approximately 43 mph/70 km/h,
the system is active and can display a rec-
ommendation to take a break.
Break recommendation
If the driver becomes less alert or fatigued,
a message is displayed in the Control Dis-
play with the recommendation to take a
break.
A recommendation to take a break is dis-
played only once during an uninterrupted
trip.
After a break, another recommendation to
take a break cannot be displayed until after
approximately 45 minutes.
System limits
The function may be limited in the follow-
ing situations and may issue 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 dur-
ing rapid acceleration or when corner-
ing 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 af-
ter parking the vehicle, for instance in the
case of a break during longer trips on high-
ways.
PostCrash – iBrake
Concept
In the event of an accident, the system can
bring the vehicle to a halt automatically
without intervention by the driver in cer-
tain situations. This can reduce the risk of a
further collision and the consequences
thereof.
At standstill
After coming to a halt, the brake is released
automatically. Secure the vehicle against
rolling.
Harder vehicle braking
In certain situations, it can be necessary to
bring the vehicle to a halt more quickly than
the Brake Assistant allows.
To do this, quickly apply extra force to the
brake. For a brief period, the braking pres-
sure will be higher than the braking pres-
