Fig. 179 In the instrument cluster display: Driver Alert System
First read and observe the introductory information and safety warningsThe Driver Alert System determines the driving behaviour at the beginning of a journey and uses it to evaluate the tiredness of the driver. This is compared to the behaviour of the driver while actually driving. If the system detects that the driver may be tired, it warns the driver with an acoustic warning signal and a message in the instrument cluster display . The message in the instrument cluster display appears for about five seconds and may be repeated once. The last displayed message is saved by the system.
The message in the instrument cluster display can be switched off by pressing the button on the windscreen wiper lever or the button on the multifunction steering wheel . The message can be displayed again in the instrument cluster display using the multifunction display .
Functional limitations
The driving behaviour can be evaluated only when the speed is above 65 km/h (40 mph) up to approximately 200 km/h (125 mph).
Switching on and off
The Driver Alert System can be activated or deactivated using the button and the and Driver assistance function buttons in the infotainment system .
Function limitations
The Driver Alert System has system-related limitations. The following conditions can limit the function of the Driver Alert System, or prevent it from working altogether:
The Driver Alert System is reset if the vehicle is stationary for longer than 15 minutes, the ignition is switched off, or the driver has unfastened his or her seat belt and opened the door.
The Driver Alert System is automatically reset in case of long slow drives (speed less than 65 km/h (40 mph)). If the speed is increased, the system evaluates the driving behaviour again.
