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‐
tive every time drive-ready state is switched on
and can thus display break recommendations.
Break recommendations can also be switched
on or off and adjusted via iDrive.
Via iDrive:
1.
"CAR"
2.
"Settings"
3.
"General settings"
4.
"Attentiveness Assistant"
5.
Select the desired setting:
▷
"Standard": the break recommendation is
issued with a defined value.
▷
"Sensitive": the break recommendation is
issued earlier.
▷
"Off": no break recommendation is is‐
sued.
Display
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.
The following settings can be selected during
the display:
▷
"Do not ask again"
▷
"Places to stop"
▷
"Remind me later"
The break recommendation is repeated after
20 minutes.
After a break, another break recommendation
cannot be displayed until after approximately
45 minutes at the earliest.
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.
