Protection of the environment
17Protection of the environment
H
Environmental not
e
DaimlerChrysler's declared policy is one of
integrated environmental protection.
The objectives are for the natural resource s
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 condition s
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. Yo u
should therefore adhere to the service
intervals.
R Always have maintenance work carrie d
out at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
Personal driving style
R Do not depress the accelerator peda l
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 eac h
gear only up to 2
/ 3of its maximum engine
speed.
R Switch off the engine in stationary traffic. Returning used vehicle
s
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

Seat belts, together with belt tensioners, belt
force limiters and airbags, are coordinate d
restraint systems. They reduce the risk of
injury in critical driving situations and thereby
increase your driving safety. However, seat
belts and airbags are generally unable to pre-
vent injuries caused by 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 86)
R the seat belt has been fastened properl y
( Y page 98)
R the airbags can inflate properly if they ar e
deployed (Y page 49)
R the steering wheel is adjusted properl y
( Y page 92)
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, bu tdoes 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 situation
s
airbag deployment would not increase th e
protection afforded to vehicle occupants,
provided they are wearing their seat belt
correctly.
On the other hand, airbag deployment only
provides increased protection if the seat
belt is worn correctly, because:
R the seat belt helps to keep the vehicl e
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 propelle d
towards the force of the impact, and is
thus better suited to prevent injury
Thus, in accident situations where an air-
bag is deployed, it only provides protection
in addition to the seat belt if the seat belt
is being worn correctly. G
Risk of injury
The restraint system may not work as inten-
ded if the following components have bee n
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 wirin g
R networked electronic system s
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
carry out any modifications on the restraint
systems. Never tamper with electronic
components and their software. G
Risk of accident and injury
Always have maintenance work carried ou t
at a qualified specialist workshop whic h
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. Safety
