The Driver Alert System informs the driver if their driving shows signs of tiredness.
Fig. 13 On the instrument cluster display: Driver Alert System symbol.
Function and operation
The Driver Alert System determines the driving behaviour of the driver at the start of a journey and
uses this to calculate a fatigue assessment. This is continuously compared with the current
behaviour of the driver while driving. If the system detects that the driver may be tired, an acoustic
warning signal will sound and a symbol Fig. 13will be displayed on the instrument cluster display
as a visual indication in combination with a supplementary text message. The message in the
instrument cluster display is displayed for about five seconds and may be repeated once. The last
displayed message is saved by the system.
The message on the instrument cluster display can be switched off by pressing the
button on the wiper lever or the button on the multifunction steering wheel Operating the
instrument clustere can be displayed again on the instrument cluster display using the
multifunction display W
Function conditions
The driving behaviour can be evaluated only when the speed is above 60 km/h (37 mph) up to
approximately 200 km/h (125 mph).
Switching on and off
The Driver Alert System can be activated and deactivated in the vehicle settings in the Infotainment
system Vehicle settings menu
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 below 60 km/h (37 mph).
Speeds above 200 km/h (125 mph).
Twisting roads.
Poor roads.
Adverse weather conditions.
Dynamic Road Sign Display (Sign Assist)
Fig. 14 On the instrument cluster display: examples of recognised speed limits and overtaking
restrictions with accompanying additional signs.
First read and observe the introductoryinformation and safety warnings
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 or overtaking restrictions. Within the limits
of the system, the system also displays additional signs, e.g. temporary restrictions, signs related to
towing a trailer Trailer towingor restrictions in wet weather conditions. In some cases, the
system can also display the current speed limits on non-signposted routes.
Displays
In addition to speed limits and overtaking restrictions, Dynamic Road Sign Display also detects the
sign which indicates that all restrictions have been lifted on motorways and main roads in Germany.
In all other countries, the currently valid speed limit is displayed instead.
The road signs detected by Dynamic Road Sign Display are displayed on the instrument cluster
Fig. 14and in some cases also on the Infotainment system, depending on which version is
installed in the vehicle. In some equipment levels, a display is also shown on the Head-up Display

Switching on and off
Continuous display of road signs in the instrument cluster can be activated and deactivated in the
vehicle settings in the Infotainment system.
After validation and evaluation of the information from the camera, the Infotainment system and
the current vehicle data, the activated Dynamic Road Sign Display shows up to three valid road signs
Fig. 14 with the accompanying additional signs:
1st position:The road sign that currently applies for the driver is shown on the left-hand side of the
display, e.g. a speed limit of 130 km/h (80 mph) Fig. 14.2nd position:Road signs that do not
always apply (e.g. 100 km/h (60 mph) in wet) are shown in second place.Additional sign:if the
windscreen wiper is active while the vehicle is in motion, the now valid road sign with the additional
In wet sign, for example, will be moved left to the first position.3rd position:Further road signs that
do not always apply will be displayed in the third position, e.g. overtaking not permitted at certain
times Fig. 14.
Speed warning
If the Dynamic Road Sign Display detects that an applicable speed limit has been exceeded, it can
issue an acoustic warning signal and display a message on the instrument cluster display.
The speed warning can be set or completely deactivated in the vehicle settings in the Infotainment
system Vehicle settings menu km/h (3 mph)
within a range between 0 km/h (mph) and 15 km/h (9 mph) above the permitted maximum speed.
Trailer mode
In vehicles with a factory-fitted towing bracket and a trailer with an electrical connection to the
vehicle, the display of road signs that may apply to the vehicle when towing a trailer, e.g. applicable
speed limits and no-overtaking signs, can be activated or deactivated in the vehicle settings in the
Infotainment system Vehicle settings menu
In trailer mode, the speed warning function display can be adjusted to the type of trailer or to legal
requirements. The settings can be adjusted in increments of 10 km/h (5 mph) within a range
between 60 km/h (40 mph) and 130 km/h (80 mph). If a higher speed is set than is permitted for
driving with a trailer in the country in which you are currently travelling, Dynamic Road Sign Display
automatically issues a warning at the usual speed limit, e.g. at 80 km/h (50 mph) in Germany.
If the speed warning for the trailer is deactivated, Dynamic Road Sign Display issues warnings as if
the vehicle was being driven without a trailer.
Function limitations
Dynamic Road Sign Display is subject to system-related limitations. The following conditions can
restrict the function of Dynamic Road Sign Display, or prevent it from working altogether:
Poor visibility, e.g. snow, rain, fog or heavy spray.
Glare, e.g. due to oncoming traffic or sunlight.
High speeds.
Covered or dirty camera.
Road signs that are located outside of the camera's field of view.
by trees, snow, dirt or other vehicles.
Road signs that do not correspond to the standard design.
Damaged or bent traffic signs.
Variable road signs on gantries (changeable road sign display using LEDs or other light sources).
Out-of-date map material in the Infotainment system.
Stickers on vehicles that show road signs, e.g. speed restrictions on trucks.
WARNING
The intelligent technology used by the Dynamic Road Sign Display cannot overcome the laws of
physics, and functions only within the limits of the system. Do not let the extra convenience afforded
by the Dynamic Road Sign Display system tempt you into taking any risks when driving. The system is
not a substitute for the full concentration of the driver.
Always adapt your speed and driving style to suit visibility, weather, road and traffic conditions.
Poor visibility, darkness, snow, rain and fog can cause road signs not to be displayed or to be
incorrectly displayed by the system.
If the camera's field of view is dirty, covered or damaged, the function of the Dynamic Road Sign
Display system may be impaired.
WARNING
Driving recommendations and traffic symbols displayed by the Dynamic Road Sign Display system
may differ from the current traffic situation.
Not all road signs can be recognised by the system and displayed correctly.
Road signs on the road and traffic regulations have priority over the recommendations and displays
provided by the Dynamic Road Sign Display system.
NOTICE
Availability of the Dynamic Road Sign Display function is limited in waypoint mode (waypoint
navigation) of the Infotainment system.
Some settings can be saved in the user accounts of the personalisation function and can therefore
change automatically when the user account is changed Personalisation

Versions and displays can vary as different versions of the instrument cluster and Infotainment
system are available.
In vehicles with fixed oil change service, services take place at predefined service intervals.
Technical progress has made it possible to considerably reduce servicing requirements. An oil change
service must only be carried out when required by the vehicle. The individual conditions in which the
vehicle is used and the driver's personal driving style are taken into account. The service reminder is
displayed 30 days before the service is due. The distance is rounded to the nearest 100 km and the
remaining time is rounded to full days.
Service alert
If a service or inspection is due soon, a service alert will appear the next time the ignition is switched
on.
The number of kilometres or amount of time shown correspond to the maximum number of
kilometres or maximum time that can still be driven before the next service.
Service event
In the event of a due service or a due inspection, a signal tone will be given when the ignition is
switched on and the spanner symbol will be displayed for several seconds on the instrument
cluster display. One of the following displays will also appear Fig. 19
