Diagnostics connection  
&
If the charge level is low, charge the bat-  
tery, e.g. by driving a considerable dis-  
tance.  
WARNING Risk of accident due to objects  
in the driver's footwell  
The diagnostics connection is a technical inter-  
face in the vehicle. It is used, for example, in the  
context of repair and maintenance work or for  
reading out vehicle data by a specialist workshop.  
Diagnostic devices should therefore only be con-  
nected by a qualiꢀed specialist workshop.  
Objects in the driver's footwell may impede  
pedal travel or block a depressed pedal.  
Please also note the information about the 12 V  
battery and short-distance trips in the "Driving  
and Parking" chapter (/ page 147).  
This jeopardizes the operating and road safety  
of the vehicle.  
#
Stow all objects in the vehicle securely  
so that they cannot get into the driver's  
&
WARNING Risk of accident due to con-  
necting devices to the diagnostics con-  
nection  
footwell.  
#
Always install the ꢂoor mats securely  
and as prescribed in order to ensure that  
there is always suꢃcient room for the  
pedals.  
If you connect devices to the diagnostics con-  
nection of the vehicle, the function of vehicle  
systems and operating safety may be  
impaired.  
#
Do not use loose ꢂoor mats and do not  
place ꢂoor mats on top of one another.  
#
For safety reasons, we recommend that  
you only use and connect products  
approved by your authorized Mercedes-  
Benz Center.

NOTE Battery discharging from using devi-  
ces connected to the diagnostics connec-  
tion  
Using devices at the diagnostics connection  
drains the battery.
