WARNING
If you connect equipment to a diagnostics
connection in the vehicle, it may affect the
operation of vehicle systems. As a result, the
operating safety of the vehicle could be affec-
ted. There is a risk of an accident.
Only connect equipment to a diagnostics con-
nection in the vehicle, which is approved for
your vehicle by Mercedes-Benz.
Change in the engine power output
!
Increased power could:
R
change emission levels
R
cause malfunctions
R
lead to consequential damage
The operating safety of the engine cannot be
guaranteed in all situations.
Any tampering with the engine management
system in order to increase the engine power
output will lead to the loss of implied warranty
entitlements.
If the vehicle's engine power output is
increased:
R
tyres, suspension, brake and engine cooling
systems must be adapted to the increased
engine power output.
R
have the vehicle recertified.
R
report changes in power output to the acci-
dent insurance body.
This will otherwise lead to the invalidation of the
vehicle’s general operating permit and its insur-
ance coverage.
If you sell the vehicle, inform the buyer of any
alterations to the vehicle's engine power output.
If you do not inform the buyer, this may consti-
tute a punishable offence under national legis-
lation.

Vehicle registration
Mercedes-Benz may ask its Service Centres to
carry out technical inspections on certain vehi-
cles. The quality or safety of the vehicle is
improved as a result of the inspection.
Mercedes-Benz can only inform you about vehi-
cle checks if it has your registration data.
In the following cases your vehicle may still not
be registered to you:
R
you did not purchase your vehicle at an
authorised specialist dealer.
R
your vehicle has not been inspected at a
Mercedes-Benz Service Centre.
It is advisable to register your vehicle with a
Mercedes-Benz Service Centre. Inform
Mercedes-Benz as soon as possible about any
change of address or vehicle ownership. You
can do this, for example, at a Mercedes-Benz
Service Centre.
