Product information
Mercedes-Benz recommends that you use
genuine Mercedes-Benz parts, conversion
parts and accessories that have been
approved for your vehicle.
Mercedes-Benz
tests genuine parts as well as
conversion parts and accessories that have
been specifically approved for your vehicle for
their reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to assess other parts. Therefore,
Mercedes-Benz accepts no responsibility for
the use of such parts in Mercedes-Benz
vehicles. This is also the case, even if they
have been independently or officially
approved. The use of non-approved parts
could affect your vehicle's operating safety.
Genuine Mercedes-Benz parts, approved
conversion parts and accessories are
available from any authorized Mercedes-Benz
Center. Here, you will receive advice about
permissible technical modifications, and the
parts will be professionally installed. Printed Operator's Manual
The
printed Operator's Manual (including any
Supplements) must be observed.
There is no electronic update to the Digital

Important safety notes
G
WARNING
Work improperly carried out on electronic
components and associated software could
cause
them to cease functioning. Because the
vehicle's electronic components are
interconnected, any modifications made may
produce an undesired effect on other
systems. Electronic malfunctions could
seriously impair the operating safety of your
vehicle.
Contact an authorized Mercedes-Benz Center
for repairs or modifications to electronic
components.
Other improper work or modifications on the
vehicle could also have a negative impact on
the operating safety of the vehicle.
Some safety systems only function when the
engine is running. You should therefore never
turn off the engine while driving. G
WARNING
Heavy blows against the vehicle underbody or
tires/wheels may cause serious damage and
impair the operating safety of your vehicle.
Such blows can be caused, for example, by
running over an obstacle, road debris or a
pothole.
If you feel a sudden significant vibration or
ride
disturbance, or you suspect that damage
to your vehicle has occurred:
R turn on your hazard warning flashers.
R slow down carefully.
R drive with caution to an area which is a safe
distance from the road.
Inspect the vehicle underbody and tires/
wheels for possible damage. If the vehicle
appears unsafe, have it towed to the nearest
authorized Mercedes-Benz Center or other qualified maintenance or repair facility for
further inspection or repairs.

conditions: 1) These devices may not cause
harmful interference, and 2) These devices
must accept any interference received,
including interference that may cause
undesired operation. Changes or
modifications not expressly approved by the

G
WARNING
If you connect equipment to the on-board
diagnostics connection, it can affect the
operation of the vehicle systems. This can
impair the operating safety of your vehicle
while driving. There is a risk of an accident.
Do not connect any equipment to the on-
board diagnostics connection. G

Loose equipment or equipment cables which
are connected to the on-board diagnostics
connection can obstruct the area around the
pedals. The equipment or the cables could
come between the pedals in the event of Introduction
23 Z

sudden braking or acceleration. This may
affect the function of the pedals. There is a
risk of an accident.
Do
not attach any equipment or cables in the
driver's footwell.
! If the engine is switched off and
equipment on the diagnostics connection
is used, the starter battery may discharge.
The diagnostics connection is only intended
for the connection of diagnostic equipment at
a qualified specialist workshop.
Connecting equipment to the diagnostics
connection can, for example, lead to
emissions monitoring information being
reset. This may lead to the vehicle failing to
meet the requirements of the next emissions
test during the main inspection. Qualified specialist workshop

qualified specialist workshop. It has the
necessary specialist knowledge, tools and
qualifications to correctly carry out the work
required
