Switching on and off
You can switch the Driver Alert System on
and off in the
Assist systems
menu in the Info-
tainment system. When the vehicle’s drive
system is activated, the Driver Alert System is
always activated too → page 31.
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:
— Speeds less than 60 km/h (37 mph).
— Speeds of more than 200 km/h (125 mph).
— Twisting roads.
— 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 follow-
ing 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 15 minutes.
The Driver Alert System is automatically reset
in the event of an extended period of slow
driving (speed less than 60 km/h (37 mph)). If
the speed is increased again, the system
evaluates the driving behaviour once more.
WARNING
The intelligent technology used in the Driv-
er 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. During a long trip, plan regu-
lar 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 lim-
itations”.
·
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 instru-
ment cluster display and respond ac-
cording to the commands.
The Driver Alert System has been de-
veloped 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
Please refer to at the start of the chap-
Dynamic Road Sign Display uses a cam-
era 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 system limits, the system also
displays an additional sign to indicate,
for example, temporary restrictions. In
some cases, the system can also display
the current speed limits on non-signpos-
ted routes.
The Dynamic Road Sign Display is always ac-
tive when the ignition is switched on. Addi-
tional signs are displayed as a generic addi-
Instrument cluster
