—When travelling at speeds of more than approximately 200 km/h(around 125 mph).
—Roads with bends.
—Road works.
—Poor roads.
—Adverse weather conditions.
—Sporty driving style.
—Driving with a trailer.
—The driver is distracted.
The Driver Alert System is reset in the following situations:
—The ignition is switched off.
—The driver seat belt is unfastened and the driver door is open.
—The vehicle has been stationary for longer than approximately 15 minutes.
The Driver Alert System is reset automatically if you drive slowly at a speed less than approx. 60 km/h(around
37 mph) for a long period. If the speed is increased, the system evaluates the driving behaviour again.
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 “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”.
● Observe 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 system fault, proceed to a qualified workshop immediately to have the system
checked.
Dynamic Road Sign Display
Dynamic Road Sign Display uses a camera in the base of the interior mirror to monitor standard road signs and
informs the driver of any detected speed limits, overtaking restrictions and danger signs. Within the limits of the
system, the system also displays additional signs, e.g. temporary restrictions or restrictions in wet or foggy
conditions. In some cases, the system can also display the current speed limits on non-signposted routes.
The Dynamic Road Sign Display is always active when the ignition is switched on.
Displays
In addition to speed limits and overtaking restrictions, Dynamic Road Sign Display also detects the road sign which
indicates that all restrictions have been lifted on motorways and main roads in Germany. In all other countries in
which the system is operated, the current speed limit is displayed instead.
The road signs detected by the Dynamic Road Sign Display system are displayed on the instrument cluster depending
