Diagnostics connection

The diagnostics connection is a technical inter‐
face in the vehicle. It is used, for example, within
the scope of repair and maintenance work or for
reading out vehicle data by a specialist work‐
shop. Diagnostic devices should therefore only
be connected by a qualified specialist workshop.
& WARNING Risk of accident due to con‐
necting devices to the diagnostics con‐
nection
If you connect devices to the diagnostics
connection of the vehicle, the function of
vehicle systems and operating safety may be
impaired.
For safety reasons, we recommend that
#
you only use and connect products
approved by your authorized Mercedes-
Benz Center.
& WARNING Risk of accident due to
objects in the driver's footwell
Objects in the driver's footwell may impede
pedal travel or block a depressed pedal.
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
footwell.
Always install the floor mats securely
#
and as prescribed in order to ensure
that there is always sufficient room for
the pedals.
Do not use loose floor mats and do not
#
place floor mats on top of one another.

connection
