be detected in time. There is risk of an acci‐
dent. Make sure that the driver is rested and
alert. Adjust the driving style to the traffic con‐
ditions.◀

Safety
After travel has begun, the system is trained
about the driver, so that decreasing alertness
or fatigue can be detected.
This procedure takes the following criteria into
account:
▷ Personal driving style, for example, steer‐
ing behavior.
▷ Driving conditions, for example, 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, 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.
