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

G
Risk of accident and injury
All work on the vehicle and, in particular,
work relevant to safety or on safety-relate d
systems must be carried out at a qualified
specialist workshop. The specialist work-
shop 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 no longer protect you and other
persons as intended. In addition, there is
the danger 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 cable s
under coverings, could cause the safet y
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 the danger
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
If you drive over obstacles at high speed or
if the vehicle bottoms out in rough terrain,
it could cause heavy impacts to the vehicl e
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 wit h
underbody protection .
You should therefore drive over obstacles
slowly and prevent the vehicle from bot-
toming out when driving off-road. If neces-
sary, have your vehicle inspected at a
qualified specialist workshop. G
Risk of accident
If work on electronic equipment and its
software is carried out incorrectly, this
equipment could stop working. The elec- tronic systems are networked via interfa-
ces. Tampering with these electronic sys-
tems could cause malfunctions in systems
which have not been modified. Malfunc-
tions such as these can seriously jeopard -
ise the vehicle's operating safety and
therefore your own safety.
You should thus have all work and modifi-
cations 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. 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

When the belt tensioners are triggered, you
will hear a bang, which will not cause any
harm to your hearing, and a small amount of
powder may also be released. The =warn-
ing lamp lights up. G
Risk of injury
If the seat belt tensioners have been trig -
gered, they provide no additional protec -
tion in the event of another accident.
Therefore, have belt tensioners which have
been triggered replaced at a qualified spe-
cialist workshop .
Comply with safety regulations when dis-
posing of belt tensioners. Any Mercedes-
Benz Service Centre can provide details of
these regulations.
Airbag s Airbag deployment slows down and restricts
the movement of the vehicle occupant.
When the airbags are triggered, you will hear

Risk of injury
Airbags provide additional protection; they
are not, however, a substitute for the sea t
belts.
Observe the following notes to reduce the
risk of serious or even fatal injury if an air-
bag is deployed:
R Vehicle occupants — in particular preg-
nant woman — must wear their seat belt
correctly at all times and lean back
against their backrest, which should be
positioned as close to the vertical as pos-
sible. The head restraint must support
the back of the seat occupant's head at
about eye level.
R Always secure children less tha n
1.50 mtall or under 12 years of age in
suitable child restraint systems.
R All vehicle occupants must select a sea t
position that is as far away from the air-
bag as possible. The driver's seat posi-
tion must allow the vehicle to be driven
safely. The driver's chest should be as far
away from the middle of the driver's fron t
airbag cover as possible. R
Move the front-passenger seat as far
back as possible, in particular, if a child
is secured in a child restraint system on
the seat.
R Vehicle occupants – in particular, chil-
dren – must not lean their head into the
area of the window in which the sidebag/
windowbag is deployed.
R Rearward-facing child restraint systems
must not be fitted to the front-passenger
seat unless the front-passenger front air-
bag has been disabled. On the front-
passenger seat, the front-passenger
front airbag is only deactivated if a child
restraint system with automatic child
seat recognition is fitted to the front-
passenger seat *.The 5 PASSENGER
AIRBAG OFF warning lamp must be li t
constantly .
If either the rearward-facing child
restraint system or the front-passenger
seat* of your vehicle does not have auto-
matic child seat recognition, childre n
must be secured in a child restraint sys-
tem on a suitable seat in the rear. If you
secure a forward-facing child restraint
system to the front-passenger seat, you Safety
