GRisk of injury
Tampering with electronic components and
their software could cause these to stop
working. Due to the networked structure of
the electronics, systems could be affected
that should not be altered in any way. Mal-
functions in the electronics could consider-
ably jeopardise the operating safety of your
vehicle.
All maintenance work should be carried out
at a qualified specialist workshop.
DaimlerChrysler recommends that you use
a Mercedes-Benz Service Centre for this
purpose, as these centres have the neces-
sary specialist knowledge and tools to carry
out the work required. In particular, all work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop.
Other work carried out incorrectly or modifi-
cations to the vehicle may also jeopardise
operating safety.
Some safety systems only function while
the engine is running. Therefore, do not
switch off the engine when driving.
Registering your vehicle
Mercedes-Benz may ask its Service
Centres to carry out technical inspections
on certain vehicles to improve their quality
or safety.
If you did not purchase your vehicle from
an authorised specialist dealer and your
vehicle has never been inspected at a
Mercedes-Benz Service Centre, it is possi-
ble that your vehicle is not registered in
your name with Mercedes-Benz.
Mercedes-Benz can only inform you about
vehicle checks if it has your registration
data.
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.
Digital speedometer and total dis-
tance recorder
Do not attempt to modify the electroni-
cally stored total distance reading for the
vehicle by tampering with the electronics.
If the total distance reading has been al-
tered and you subsequently sell the ve-
hicle but do not inform the buyer, this may
constitute a punishable offence under lo-
cal legislation.
Changing the engine power output
Any tampering with the electronic engine
management system in order to increase
the engine power output will lead to the in-
validation of the vehicle’s general operat-
ing permit and its insurance cover as well
as to the loss of guarantee and warranty
rights.
Changes in power output require the ve-
hicle to be recertified and must be re-
ported to the vehicle insurers. Tyres, sus-
pension, brakes and cooling systems must
be adapted to the increased engine power
output.
Tampering with the electronic engine man-
agement system will change emission lev-
els and the operating safety of the engine
cannot always be guaranteed. Increased
power could cause malfunctions and con-
sequential damage to other assemblies.
If the power output of the vehicle’s engine
has been modified and you subsequently
sell the vehicle but do not inform the
