Protection of the environment
H
Environmental note
Daimler's declared policy is one of integrated
environmental protection.
The objectives are for the natural resources
which form the basis of our existence on this
planet to be used sparingly and in a manner
which takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally-responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tyre wear depend on
the following factors:
R operating conditions of your vehicle
R your personal driving style
You can influence both factors.
You should bear the following in mind:
Operating conditions
R avoid short trips as these increase fuel con-
sumption.
R make sure that the tyre pressures are
always correct.
R do not carry any unnecessary weight.
R keep an eye on the vehicle's fuel consump-
tion.
R remove roof racks once you no longer need
them.
R a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R always have maintenance work carried out
at a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
Personal driving style R
do not depress the accelerator pedal when
starting the engine.
R do not warm up the engine with the vehicle
stationary.
R drive carefully and maintain a safe distance
from the vehicle in front.
R avoid frequent, sudden acceleration.
R change gear in good time and use each gear
only up to 2
/ 3of its maximum engine speed.
R switch off the engine in stationary traffic. Returning used vehicles
Mercedes-Benz will take back your
Mercedes-Benz to dispose of it in an environ-
mentally-responsible manner, in accordance
with the European Union (EU) End of Life
Vehicles Directive.
The End of Life Vehicles Directive applies to
vehicles of up to 3.5 t gross vehicle weight, in
accordance with national regulations. For
several years, Mercedes-Benz has been
meeting all the legal requirements for a
design which allows for recycling and re-use.
There is a network of return points and dis-
assembly plants which can recycle your vehi-
cle in an environmentally-responsible man-
ner. The options for recycling vehicles and
parts are constantly being developed and
improved. This means that your Mercedes-
Benz will also continue to meet even the
increased recycling quotas in the future in
good time. You can obtain further information
from your national Mercedes-Benz homepage
or your national hotline number. Introduction

Operating safety
Safety notes
G
Risk of accident and injury
Always have work on the vehicle carried out
by a qualified specialist workshop. In particu-
lar, work relevant to safety or on safety-rela-
ted systems as well as maintenance work
must be carried out at a qualified specialist
workshop. The workshop must have the nec-
essary specialist knowledge and tools to carry
out the work required. Mercedes-Benz rec-
ommends 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 vehicle may not
function correctly and as a result will no lon-
ger protect you and other persons as inten-
ded. In addition, there is a risk that you may
lose control of your vehicle 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 sys-
tems of your vehicle to stop working properly.
The safety systems would thus no longer pro-
tect you and other persons as intended. In
addition, there is a risk that you may lose con-
trol of your vehicle and thus cause an acci-
dent.
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
If you drive over obstacles at high speed or if
the vehicle bottoms out in rough terrain, it
could cause heavy impacts to the vehicle
underbody, tyres or wheels. This could cause your vehicle to be damaged, which in turn
might lead to an accident. This also applies to
vehicles which are equipped with underbody
protection.
You should therefore drive over obstacles
slowly and prevent the vehicle from bottom-
ing out when driving off-road. If necessary,
have your vehicle inspected at a qualified spe-
cialist workshop. G
Risk of accident
If work on electronic equipment and its soft-
ware is carried out incorrectly, the equipment
could stop functioning. The electronic sys-
tems are networked via interfaces. Tampering
with these electronic systems could cause
malfunctions in systems which have not been
modified. Such malfunctions 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.
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. 18 Introduction

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 warn-
ing 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 recognise
certain dangers. Introduction
