Introduction
Fig. 1 On the display of the instrument cluster: Driver Alert
System symbol.
The Driver Alert System informs the driver if their driving shows signs of tiredness.
The Driver Alert System determines the driving behaviour at the beginning of a journey and uses it to evaluate the
tiredness of the driver. The Driver Alert System is constantly compared to the behaviour of the driver while actually
driving. If the system detects driver fatigue, an acoustic warning signal will sound and a symbol will be displayed on
the instrument cluster display together with a supplementary text message → Fig. 1. The message on the instrument
cluster display appears for about 5 seconds and may be repeated once. The last displayed message is saved by the
system.
Function conditions
The driving behaviour can be evaluated only when the speed is above 60 km/h(around 37 mph) up to approximately
200 km/h (around 125 mph).
WARNING
The intelligent technology used in the Driver Alert System cannot overcome the laws of physics, and functions only
within the limits of the system. Do not let the extra convenience afforded by the Driver Alert System tempt you into
taking any risks when driving – this can cause accidents. During a long trip, plan regular and sufficient breaks.
● The driver is responsible at all times for their fitness to drive.
● Never drive a vehicle when you are tired.
● The system cannot always detect the driver's level of alertness. Observe the information in the section on
function limitations.
● In certain situations, the system may wrongly interpret intentional driving manoeuvres as a lack of alertness from
the driver.
● No urgent warning will be given in the event of the phenomenon known as microsleep!
● Follow the information in the instrument cluster display, and respond according to the commands.
The Driver Alert System has been developed for use only while driving on motorways and good
roads.
If there is a fault in the system, go to a suitably qualified workshop and have the system
checked.
