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. re-routing 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, this equipment
could stop working. The electronic systems
are networked via interfaces. Tampering with
these electronic systems could cause mal-
functions in systems which have not been
modified. Malfunctions such as these can
seriously jeopardise the vehicle's operating
safety and therefore your own safety.
You should therefore have all work and mod-
ifications to electronic components carried
out at a qualified specialist 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

Occupant safety
Notes on occupant safety
Seat belts, together with belt tensioners, belt
force limiters and airbags, are complemen-
tary, coordinated restraint systems. They
reduce the risk of injury in specific, pre-
defined types of accident situations and
thereby increase occupant safety. However,
seat belts and airbags generally do not pro-
tect against objects penetrating the vehicle
from the outside.
To ensure that the restraint systems can
deliver their full potential protection, make
sure that:
R the seat and head restraint are adjusted
properly (Y page 64).
R the seat belt has been fastened properly
(Y page 75).
R the airbags can inflate properly if they are
deployed (Y page 37).
R the steering wheel is adjusted properly
(Y page 70).
R the restraint systems have not been modi-
fied.
i An airbag increases the protection of
vehicle occupants wearing a seat belt.
However, airbags are only an additional
restraint system which complements, but
does not replace, the seat belt. All vehicle
occupants must wear their seat belt cor-
rectly at all times, even if the vehicle is
equipped with airbags. This is because – on
the one hand – airbags are not deployed in
all types of accident, as in some situations
airbag deployment would not increase the
protection afforded to vehicle occupants,
provided they are wearing their seat belt
correctly. On the other hand, airbag deploy-
ment only provides increased protection if
the seat belt is worn correctly because: R
the seat belt helps to keep the vehicle
occupant in the best position in relation
to the airbag.
R for example, in a head-on collision, the
seat belt can more adequately prevent
the occupant from being propelled
towards the point of the impact, and is
thus better suited to prevent injury.
Therefore, in accident situations where an
airbag is deployed, it only provides protec-
tion in addition to the seat belt if the seat
belt is being worn correctly. G
Risk of accident and injury
Always have maintenance work carried out at
a qualified specialist workshop which has 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 pur-
pose.
In particular, work relevant to safety or on
safety-related systems must be carried out at
a qualified specialist workshop. If this work is
not carried out correctly, the operating safety
of your vehicle may be affected. There is a risk
of an accident and injury. G
Risk of injury
The restraint system may not work as inten-
ded if the following components have been
modified or work on these components has
not been performed correctly:
R restraint system, consisting of the seat
belts and anchorages, belt tensioners, belt
force limiters, airbags
R wiring
R networked electronic systems
Airbags or belt tensioners could then fail, e.g.
in the event of an accident in which the decel-
eration force would normally be high enough
to trigger the systems, or they could be trig-
gered unintentionally. Never carry out any
modifications on the restraint systems. 34

Risk of injury
When cleaning the steering wheel boss and
dashboard, do not use cockpit sprays or
cleaning agents containing solvents. Cleaning
agents containing solvents cause the surface
to become porous, and as a result plastic
parts may break away and be thrown around
the interior when an airbag is deployed which
may result in severe injuries.
X Wipe the dashboard and steering wheel
boss with a damp, lint-free cloth (e.g. a
microfibre cloth) and cleaning agent.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
Cleaning the COMAND display X
Before cleaning the display, make sure that
it is switched off and has cooled down.
X Clean the display surface using a commer-
cially-available microfibre cloth and TFT/
LCD display cleaner.
X Dry the display surface using a dry micro-
fibre cloth.
! For cleaning, do not use any of the fol-
lowing:
R alcohol-based solvents or petrol
R abrasive cleaning agents
R commercially-available household clean-
ing agents
These may damage the display surface. Do
not exert pressure when cleaning the dis-
play surface as this may lead to irreversible
damage.
Cleaning the seat covers !
Do not use microfibre cloths to clean gen-
uine leather, artificial leather or 204
