Modifying the engine output
! Increased power could:
R

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 output
will lead to the loss of warranty entitlements.
If the vehicle's engine output is increased:
R
tyres, suspension, brake and engine cooling
systems must be adapted to the increased
engine output
R
have the vehicle recertified
R
report changes in power output to the vehi-
cle insurers
This will otherwise lead to the invalidation of
the vehicle's general operating permit and its
insurance coverage.
If you sell the vehicle, inform the buyer of any
alterations to the vehicle's engine output. If
you do not inform the buyer, this may consti-
tute a punishable offence under national legis-
lation.
Qualified specialist workshop
A qualified specialist workshop has the neces-
sary specialist knowledge, tools and qualifica-
tions to carry out the work required on the
vehicle correctly.
This is particularly applicable to work relevant
to safety. Observe the notes in the Mainte-
nance or Service Booklet.
You should always have the following work on
your vehicle carried out at a qualified special-
ist workshop:

Mercedes-Benz Service Centre.
! Have the engine electronics and associ-
ated parts, such as control units, sensors,
actuating components or electric cables
serviced only at a qualified specialist work-
shop. Vehicle components may otherwise
wear more quickly and the vehicle's operat-
ing permit may be invalidated.
Vehicle registration
Mercedes-Benz may ask its Service Centres to
carry out technical inspections on certain vehi-
cles. This is always the case if it is possible to
improve quality or safety levels. Mercedes-
Benz can only inform you about vehicle checks
if it has your registration data.
