Safety information
WARNING
The system does not relieve from per‐
sonal responsibility to 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 accident. Make sure
that the driver is rested and alert. Adjust driv‐
ing style to traffic conditions.◀
Function
The system is activated each time the engine
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 de‐
tected.
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 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.
