Thank you for choosing Mercedes-Benz.
Before you drive off, familiarise yourself with
your vehicle and read the Owner's Manual.
This will help you to obtain the maximum
pleasure from your vehicle and to avoid
endangering yourself and others.
Items of optional equipment are marked with
an asterisk *.
The equipment in your vehicle may vary,
depending on the model, the ordered items,
the country specifications and availability.
The illustrations in this Owner's Manual show
a left-hand-drive vehicle. The arrangement of
the switches, levers, stowage compartments,
etc. will differ accordingly in a right-hand-
drive vehicle.
Mercedes-Benz is constantly updating its
vehicles to the state of the art and therefore
reserves the right to introduce changes in
design, equipment and technical features at
any time. You cannot, therefore, base any
claims on the data, illustrations or descrip-
tions in this Owner's Manual.
Please consult a Mercedes-Benz Service
Centre if you have any questions.
The Owner’s Manual, Brief Instructions,
service booklet and supplements related to
vehicle equipment belong with the vehicle.

Safety notes
G
Risk of accident and injury
Always have work on the vehicle carried out
by a qualified specialist workshop. In par-
ticular, work relevant to safety or on safety-
related systems as well as maintenance
work must be carried out at a qualified spe-
cialist workshop. The workshop must have
the necessary specialist knowledge and
tools to carry out the work required.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose. G
Risk of accident and injury
Some safety systems only function when
the engine is running. You should therefore
never switch off the engine when driving.
Otherwise, the safety systems of your vehi-
cle may not function correctly and as a
result will no longer protect you and other
persons as intended. In addition, there is a
risk that you may lose control of your vehi-
cle and thus cause an accident. G
Risk of accident and injury
Work carried out incorrectly, or alterations
made to the vehicle, e.g. rerouting of cables
under coverings, could cause the safety
systems of your vehicle to stop working
properly. The safety systems would thus no
longer protect you and other persons as
intended. In addition, there is a risk that you
may lose control of your vehicle and thus
cause an accident.
All work and alterations to the vehicle, e.g.
installations or modifications, should there-
fore be carried out at a qualified specialist
workshop. G
Risk of accident
A heavy impact to the underbody, tyres or
wheels, for example when bottoming out on
rough terrain or driving over an obstacle at
high speed, could damage your vehicle. As
a result, you could cause an accident. This
also applies to vehicles which are equipped
with underbody protection.
For this reason, drive slowly over obstacles,
avoid bottoming out the vehicle in rough
terrain and, if necessary, have your vehicle
checked at a qualified specialist workshop. G
Risk of accident
If work on electronic equipment and its
software is carried out incorrectly, the
equipment could stop functioning. The
electronic systems are networked via inter-
faces. Tampering with these electronic sys-
tems could cause malfunctions in systems
which have not been modified. Such mal-
functions can seriously compromise the
vehicle’s operating safety and your own
safety as well.
Have all work on and modifications to elec-
tronic components carried out at a qualified
workshop. 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-
Benz Service Centre, it is possible 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. Introduction

Operating safety
17
It is advisable to register your vehicle with a
Mercedes-Benz Service Centre.
Inform Mercedes-Benz as soon as possible
about any change in address or vehicle own-
ership.
Correct use
Observe the following information when using
your vehicle:
R The safety notes in this manual
R The "Technical data" section in this manual
R National road traffic regulations
R National road traffic licensing regulations G
Risk of injury
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
warning stickers unless the sticker clearly
states that you may do so.
If you remove the warning stickers, you or
others could be injured by failing to recog-
nise certain dangers. Introduction
