System limitation
The system displays a message about system limitation in the following cases.
▶
The map documents are not up to date.
▶
The vehicle is located in an area for which no map documents are present.
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.
The system evaluates the steering behaviour at speeds of 60-200 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 menu
tance.
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

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.

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
strument cluster and an audible signal
The system can only function properly if the tyres have the prescribed inflation
pressure and these pressure values are stored in the system.
Always save the tyre pressure values in the system if one of the following
events occurs.
Change of tyre pressure values.
▶
Change one or more wheels.
▶
Change in position of a wheel on the vehicle.
▶
▶
The warning light in the instrument cluster.

Having the correct tyre inflation pressure is always the driver's responsi-
■
bility. Tyre pressure should be checked regularly
The system cannot warn in case of very rapid tyre inflation pressure loss,
■
e.g. in case of sudden tyre damage.
Before storing the pressures, the tyres must be inflated to the specified
■
inflation pressure
» page
289. If the wrong pressure valuesare stored, the
system may not issue any warnings, even if the tyre pressure is too low.
CAUTION
To ensure proper system function, the tyre pressure values must be stored ev-
ery 10,000 km or 1x a year.
