Malfunctions and information messages
Read and observe
on page 246 first.
If, for some unknown reason, the system is not available, an appropriate mes-
sage appears in the display of the instrument cluster.
Sensor covered / dirty
If the screen in the sensor area is dirty, iced or misted, a caution to clean the
screen appears. Clean the windscreen or remove the obstacles from the sen-
sor area.
System fault
In the case of a system fault, an error message appears. Seek help from a spe-
cialist garage.
System limitation (Navigation data not available)
If the Infotainment Navigation submits no data, a message regarding the limi-
tation of the system function appears. Check whether the map documents are
up to date or whether the vehicle is currently in a location for which no naviga-
tion data are available.
Fatigue detection
The fatigue detection system (following known as system) recommends the
driver taking a break from driving when, because of the driver's steering be-
haviour, driver fatigue can be detected.
From the starting of the journey, the system evaluates the steering behaviour
at speeds 65-200 km/h. If, while driving, there have been changes in the steer-
ing behaviours that are evaluated by the system as indicating possible fatigue,
a break recommendation is issued.
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 menu

tance
in the infotainment system.
Pause recommendation
The icon appears and the following message for a few seconds in the display
of the instrument cluster and a message about the detected fatigue. An au-
dible signal is also emitted.
WARNING
■
Please take note of the general points relating to the use of assistance
systems » page 208, 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 may evaluate the driving incorrectly and thus
mistakenly recommend a break (e.g. sporty driving, adverse weather condi-
tions or poor road conditions).
■
The system is designed primarily for use on motorways.
Tyre pressure monitoring
Introduction
The tyre pressure monitoring function (following known as system) monitors
the tyre pressure while driving.
If the tyre inflation pressure changes, the warning light
lights up in the in-
strument cluster and an audible signal sounds » page 37.
The system can only function properly if the tyres have the prescribed inflation
pressure and these pressure values are stored in the system.
