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. On-board diagnostics interface
G
WARNING
If you connect equipment to the on-board
diagnostics interface, 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 accident. Do not connect any equipment to the on-
board diagnostics interface.
G
WARNING
Loose equipment or equipment cables which
are connected to the on-board diagnostics
interface can obstruct the area around the
pedals.  The 
equipment or the cables could get
between the pedals in the event of sudden
braking or acceleration. You may then no
longer be able to brake, operate the clutch or
accelerate as intended. There is a risk of
accident.
Do not attach any equipment or cables in the
driver footwell.
Connecting equipment to the on-board
diagnostics interface can lead to emissions
monitoring information being reset. This may
lead to the vehicle failing to meet the
requirements at the next special emissions
test or main inspection.
If the engine is switched off and equipment
which is connected to the on-board
diagnostics interface is used, the starter
battery may discharge.
The on-board diagnostics interface is only
intended for the connection of diagnostic
equipment at a qualified specialist workshop. Qualified specialist workshop
An authorized Mercedes-Benz Center is a
qualified specialist workshop. It has the
necessary specialist knowledge, tools and
qualifications to correctly carry out the work
required  on 
your vehicle. This is especially the
case for work relevant to safety.
Observe the notes in the Maintenance
Booklet.
Always have the following work carried out at
an authorized Mercedes-Benz Center:
