Sporty driving style.
Towing a heavy/long 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 opened.
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 driving at slow
speeds (speed less than 60 km/h (37 mph)). When the speed is increased again, the system
evaluates the driving behaviour once more.

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. 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
Function limitations section.
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 act 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, go to a qualified workshop and have the system checked.

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⇒Introduction 
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 towing  or 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. 14  and 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
⇒ Instrument cluster .

valid map data is loaded in the Infotainment system. OR: the vehicle is located in an area that is not
covered by the map stored in the Infotainment system.No data availableDynamic Road Sign Display
is not supported in the country in which you are currently travelling.
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.

Display of road signs
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 . The settings can be adjusted in increments of 5 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.

Please note that the sensors in the door handles can be activated by a powerful jet of water or
steam if a valid vehicle key is simultaneously within the operating range. If at least one window is
open and sensor surfaces on the door handles are continuously activated, all windows will close. All
windows could open if the jet of water or steam is moved away from the door handle sensors briefly
and then moved back again ⇒  .

It may not be possible to lock or unlock the vehicle using the Keyless Access if the 12-volt vehicle
battery or button cell in the vehicle key is weak or discharged. The vehicle can be locked or unlocked
manually ⇒  .

If there is no valid vehicle key in the vehicle or if it is not detected, a corresponding message will be
shown on the instrument cluster display. This may occur if the vehicle key is exposed to interference
from another radio signal or is covered by another item, e.g. an aluminium case ⇒ Starting and
stopping the engine .
Anti-theft alarm
Depending on the vehicle equipment level, the vehicle may have an anti-theft alarm.
The anti-theft alarm is activated automatically when the vehicle is locked using the vehicle key.
The anti-theft alarm outputs acoustic and visual warning signals for up to five minutes.
When does the system trigger an alarm?
If a door is opened.
If the bonnet is opened.
If the boot lid is opened.
If the ignition is switched on with a valid vehicle key. (The alarm may sound briefly.)
If the 12-volt vehicle battery is disconnected.
If there is movement inside the vehicle (in vehicles with interior monitoring) ⇒ Interior monitoring
system and anti-tow alarm .
If the vehicle is lifted or towed (vehicles with anti-tow alarm) ⇒ Interior monitoring system and anti-
tow alarm .
If the vehicle is transported on a car ferry or by rail (vehicles with anti-tow alarm or interior
monitoring) ⇒ Interior monitoring system and anti-tow alarm .
If a trailer that is connected to the anti-theft alarm system is removed ⇒ Trailer towing .
Switching off the alarm
Unlock the vehicle using the unlocking button on the vehicle key.

Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Boot lid cannot be opened or closed
Check whether the boot lid is blocked by an obstacle. The boot lid can be moved by hand. You will
need to use increased force for this.
The drive switches off automatically in order to prevent overheating if the boot lid is operated too
frequently in a short space of time. Until the drive has cooled down, the boot lid can be opened and
closed by hand using more force than usual.
When you tow a trailer, the electrical boot lid can only be opened and closed on the boot lid
⇒ Trailer towing .
The boot lid must be closed by hand if the 12-volt vehicle battery or fuse is disconnected or faulty.
All turn signals flash four times
The vehicle key used last is still in the vehicle.
Boot lid is stiff
At outside temperatures below freezing point, the opening mechanism cannot always lift the
partially opened boot lid automatically. In this case, guide the boot lid further up by hand.
