journeys.�It�is�part�of�the�Active�Protection�equipment�(OE�5AL)�included�in�the�basic�equipment.

A�change�in�the�driver's�driving�behavior�is�perceived�by�the�attentiveness�assistant.�In�the�event

of�increasing�inattentiveness�or�if�the�driver�is�tired,�the�alertness�assistant�shows�a�display

recommending�that�the�driver�take�a�break�as�a�Check�Control�message�in�the�central�information

display�(CID).

The�alertness�assistant�is�automatically�active�after�each�engine�start�from�a�speed�of�roughly�70km/h.

If�the�system�is�active,�a�driving�behavior�profile�is�created�at�the�beginning�of�a�journey.�The�following

criteria�are�taken�into�consideration:

• Personal�driving�style,�for�example�the�steering�behavior

• Driving�conditions,�for�example�the�time�or�journey�duration

• Breaks�during�a�long�journey

• Journey�duration.

duration�of�20�minutes).

The�break�recommendation�is�only�displayed�once�during�an�uninterrupted�journey�(except�when

"Remind�later"�is�selected).

After�a�break�a�new�break�recommendation�is�not�shown�during�the�next�45�minutes�of�the�journey.

The�system�is�reset�if�a�break�is�longer�than�50minutes�or�if�the�break�lasts�longer�than�the�last�driving

time.�The�driving�behavior�is�re-taught.
