WARNING
If you connect equipment to the 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 accident.
Do not connect any equipment to the diag-
nostics connection. G
WARNING
Loose equipment or equipment cables that
are connected to the diagnostics connection
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. As a result, the movement of the
pedals may be impaired. There is a risk of
accident.
Do not attach any equipment or cables in the
driver footwell.
! If the engine is switched off and equip-
ment 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 emis-
sions monitoring information being reset.
This may lead to the vehicle failing to meet
the requirements of the nex temissions test
during the main inspection. Qualified specialist workshop
Aq ualified specialist workshop has the nec-
essary specialist knowledge, tools and quali-
fications to correctl ycarry out the work required on your vehicle
.This is especially the
case for work relevant to safety.
Observe the information in the Service Book-
let.
Always have the following work carried out at
a qualified specialist workshop:
R work relevant to safety
R service and maintenance work
R repair work
R alterations, installation work and modifica-
tions
R work on electronic components
Mercedes-Ben zrecommends that you use a
Mercedes-Benz Service Centre. Vehicle registration
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-
BenzS ervice Centre, it is possible that your
vehicle is not registered in your name with
Mercedes-Benz. Mercedes-Benz can only
infor myou about vehicle checks if it has your
registration data.
It is advisable to register your vehicle with a
Mercedes-Benz Service Centre.

WARNING
Various warning stickers are affixed to your
vehicle. Their purpose is to draw your atten-
tion, and the attention of others, to various
dangers. Therefore, do not remove any warn-
ing stickers unless the sticker clearly states
that you may do so. 22
Introduction

If you remove the warning stickers, you or
others could be injured by failing to recognise
certain dangers.
When driving yourv ehicle observe the follow-
ing information:
R the safety notes in this manual
R the "Technical data" section in this manual
R traffic rules and regulations
R laws and safety standards pertaining to
moto rvehicles Implied warranty
! Observe the notes in these Operating
Instructions about the correct operation of
your vehicle as well as about possible dam-
age to the vehicle. Damage to your vehicle
that arises from culpable contravention of
these instructions is not covered by the
Mercedes-Benzi mplied warranty of
Daimler AG. Data stored in the vehicle
Fault data
Components critical for vehicle operation are
equipped with fault data memories as stand-
ard. There are also data storage devices
which record the technical reactions of vehi-
cle components to certain driving situations
(e.g. airbag deployment or ESP ®
interven-
tion).
This data is used exclusively to:
R assist in the rectificatio noffaults and
defects
R help Mercedes-Ben zoptimise and develop
vehicle functions
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced by Mercedes-
Benz, this technical information can be read
out from the fault memory. This is performed
by authorised employees of the Mercedes- Ben
zservice network using special diagnos-
tic computers.
After a fault has been rectified, the informa-
tion is deleted from the memory. Other mem-
ory data is constantly overwritten. Other devices that store data
Depending on the equipment level, your vehi-
cle may feature communications and/or
entertainment systems (e.g. navigation devi-
ces, telephone systems). These allow you to
save and edit data required for the operation
of the respective device.
Further information on operation (e.g. on
deleting data) can be found in the separate
operating instructions. Introduction
