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.

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 
 
  

RNING 
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.

First read and observe the introductory information and safety warnings
The service event displays are shown on the instrument cluster Fig. 19and 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.  

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!

you may find that system settings (time, date, personal convenience settings and programming) and 
user accounts have been changed or deleted. Check and correct the settings as necessary once the 
12-volt vehicle battery has been sufficiently charged.

 needle may move further in a clockwise direction under high engine 
loads and at high outside temperatures. This is no cause for concern unless the indicator lamp 
in the instrument cluster display is lit up or flashing Engine oil 
Adapting the display areas to the driving situation 
Choose the three possible instruments corresponding to your individual driving style and the driving 
situation. 
 
WARNING 
Accidents and injuries can occur if the driver is distracted. Operating the Infotainment system can 
distract you from the road. 
Always drive carefully and responsibly. 
 
NOTICE 
When starting from cold, avoid high engine speeds, driving at full throttle and over-loading the 
engine. 
 
Due to the principle of performance determination used in the vehicle, the physical accuracy of the 
displayed values is not guaranteed. 
Lap timer 
First read and observe the introductoryinformation and safety warnings
The lap timer provides you with the option of timing your own laps manually in the vehicle on a race 
track, storing the times and comparing them with previously measured best times.
