Driver alert system (interval recommendation) Turning on and off Depending on the vehicle and radio version, the Driver Alert System can be activated or deactiva- ted through the radio system with the button OR by through the settings button . Simply touch the function button Car → page 28. Please refer to at the start of the chapter on page 15. Operating limitations The alertness detection system has system limi- tations. The following conditions may cause the alertness detection system to operate only in a limited way or not to operate altogether: – Speeds below 60 km/h. Fig. 17 On the instrument cluster display: driver alert system icon. – Speeds above 200 km/h. – Curvy stretches.
The driver alert system warns the driver when his driving attitude indicates tired- ness. – Roads in poor condition. – Unfavourable climate conditions. – When the driver is too inattentive. Under the following conditions the driver alert system gets reset: Depending on the vehicle version, the driver alert system indicator may not be available. – Ignition is turned off. Function and operation The driver alert system warns the driver when his driving attitude indicates tiredness. – Driver's safety belt is loose and the driver door is open. – The vehicle is standing still for over 15 mi- nutes.
The driver alert system senses the driving behav- iour at the beginning of a trip and from this de- rives possible weariness indications. This is con- stantly compared to the actual driving behaviour. Should the system detect signs of fatigue of the driver, it sounds a “gong” alarm and displays a visual warning with an icon → Fig. 17 on the dis- play of the instrument cluster together with a supplementary text message. The text message on the instrument cluster display is displayed for about 5 seconds and, if necessary, is repeated once. The last message is saved by the system.
When driving over a longer period at low speed (less than 60 km/h), the assessment is automati- cally reset by the system. When driving faster later on, the driving behaviour is recalculated. WARNING The intelligent alertness detection technology is not able to overcome physical limitations and operates only within the limitations of the sys- tem. The higher level of convenience provided by the alertness detection system should not encourage the driver to take risks. When driv- ing over longer distances take regular and long enough breaks.
The message on the instrument cluster display can be turned off by pressing the button on the wipers lever or the button on the mul- tifunction steering wheel → page 27. The mes- sage on the instrument cluster display may be accessed again through the multifunction indica- tor → page 23. ● The driver is ultimately always responsible for his driving capacity. ● Never drive a vehicle when tired. ● The system does not recognize a low level of alertness under all circumstances. Observe the information provided in section “Opera- tional limitations” → page 24. Operating conditions Driving behaviour is only assessed at speeds be- tween 60km/h and approximately 200km/h.
