Protection of the environment
15Protection of the environment
H
Environmental note
Daimler's declared policy is one of integra-
ted 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 environ-
ment by operating your vehicle in an envi-
ronmentally-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
consumption.
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 con-
sumption.
R remove roof racks once you no longer
need them.
R a regularly serviced vehicle will contrib-
ute 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 vehi-
cle stationary.
R drive carefully and maintain a safe dis-
tance 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

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

Occupant safety
36 Occupant safety
Notes on occupant safety
Seat belts, together with belt tensioners, belt
force limiters and airbags, are coordinated
restraint systems. They reduce the risk of
injury in defined 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, you
should ensure that:
R the seat and head restraint are adjusted
properly (Y page 63)
R the seat belt has been fastened properly
(Y page 72)
R the airbags can inflate properly if they are
deployed (Y page 39)
R the steering wheel is adjusted properly
(Y page 69)
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 force 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
purpose.
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 oper-
ating safety of your vehicle may be affec-
ted. 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
deceleration force would normally be high
enough to trigger the systems, or they
could be triggered unintentionally. Never Safety
