Fatigue detection system
The fatigue detection system (hereinafter simply the system) advises the driv-
er to take a break from driving when driver fatigue can be detected based on
the driver's steering behaviour.
The system evaluates the steering behaviour at speeds of 65-200 km/h.
Conditions under which a break from driving is detected by the system
▶
The vehicle is stopped and the ignition switched off.
▶
The vehicle is stopped, the seat belt removed and the driver's door opened.
▶
The vehicle is stopped for more than 15 minutes.
If none of these conditions are met or if the driving style is not changed, the
system recommends a driving break again after 15 minutes.
The system can be activated/deactivated in Infotainment menu

WARNING
■
The general information relating to the use of assistance systems must be
observed » page 169, in section Introduction.
■
For the driving ability is always the driver's responsibility. Never drive if
you feel tired.
■
The system may not detect all cases where a break is needed.
■
Therefore, take regular, sufficient breaks during long trips.
■
There will be no system warning during the so-called micro-sleep.
Note
■
In some situations, the system can evaluate the steering behaviour incorrect-
ly and therefore falsely display a break recommendation.
■
The system is designed primarily for use on motorways.
