Function
The system is switched on every time drive-
ready state is switched on.
After commencement of the journey, the system
adapts to the driver so that an decrease in atten‐
tion or fatigue can be detected.
This process considers the following criteria:
▷ Personal driving style, for example, steering.
▷ Driving conditions, for example, time of day,
duration of journey.
The system is active from approx. 70 km/h,
43 mph and can also display a recommendation
to take a break.
Recommendation to take a break
Adjusting
The attentiveness assistant is automatically ac‐

2. "Settings"
3. "General settings"
4. "Attentiveness Assistant"

▷ "Standard": the break recommendation is
issued with a defined value.
▷ "Sensitive": the break recommendation is
issued earlier.
▷ "Off": no break recommendation is is‐
sued.

If the driver's attention drops or he/she becomes
tired, a message is shown on the Control Display
with the recommendation to take a break.

System limits
The system may have limited functionality in sit‐
uations such as the following and an incorrect
warning, or no warning at all, may be output:
▷ If the time is set incorrectly.
▷ When the speed is predominantly below ap‐
prox. 70 km/h, 43 mph.
▷ If a sporty driving style is adopted, for exam‐
ple sharp acceleration or fast cornering.
▷ In active driving situations, for example fre‐
quent lane changes.
▷ In poor road conditions.
▷ In strong crosswinds.
The system is reset approximately 45 minutes
after the vehicle is stopped, for example when
taking a break during a long motorway journey.
