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.
Partially or fully hidden traffic signs, e.g. 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Out-of-date map material in the Infotainment system.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 .
WARNING
Driving when the fuel level is too low can lead to the vehicle coming to a standstill in traffic,
potentially causing accidents and serious injuries.
When the fuel level is too low, the fuel supply to the engine could be irregular, especially when
driving up or down hills and inclines.
The steering, all driver assist systems and brake support systems stop working if the engine sputters
or goes off due to fuel shortage or irregular fuel supply.
Always fill the tank when it is still 1/4 full. This reduces the risk of running out of fuel and breaking
down.
NOTICE
Do not run the tank empty. The irregular fuel supply can cause misfiring and allow unburnt fuel to
enter the exhaust system. The catalytic converter or particulate filter could be damaged as a result.
The small arrow next to the petrol pump symbol in the fuel gauge shows you the side of the vehicle
on which the tank flap is located.
Coolant temperature display

First read and observe the introductory information and safety warnings⇒Introduction
Cold area. The engine has not yet reached operating temperature. Avoid high engine revs and
heavy engine loads until the engine is warm.
Normal area.
Warning area. The temperature may also rise to the hot area when the engine is working hard,
especially at high ambient temperatures.
Coolant
The indicator lamp lights up and the central warning lamp flashes red.
The coolant level is not correct or there is a fault in the coolant system.
Do not drive on!
Stop the vehicle, switch off the engine and allow it to cool down.
Check the coolant level ⇒ Coolant .
Seek expert assistance if the warning lamp does not go out although the coolant level is adequate.
Service interval display
Fig. 19 In the instrument cluster display: display example for a due service event (illustration).
First read and observe the introductory information and safety warnings⇒Introduction
The service event displays are shown on the instrument cluster ⇒ Fig. 19 and in the Infotainment
system.
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.
In vehicles with flexible oil change service, the service intervals are calculated on an individual basis.
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 :
Inspection now!
Oil service now!
Oil service and inspection now!
