Protection of th
eenvironment Notes
H
Environmental note
Daimler's declared polic yisone of integrated
environmental protection.
The objectives are for the natural resources
which form the basis of our existence on this
plane ttobeu sed sparingl yand in amanner
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 shoul dbear the following in mind:
Operating conditions
R avoid short trips as these increase fuel con-
sumption.
R mak esure 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 ar egularly serviced vehicle will contribute
to environmental protec tion. You should
therefor eadhere to the service inter vals.
R always have maintenance work carried out
at aq ualified specialist workshop ,e.g. a
Mercedes-Benz Service Centre.
Personal driving style
R do not depress the accelerator pedal when
starti ngthe engine.
R do not warm up the engine with the vehicle
stationary. R
drive carefully and maintain asafe 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
/ 3 of 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 tgros svehicle weight, in
accordance with national regulations. For
sever alyears, Mercedes-Benz has been
meeting all the lega lrequirements for a
design which allows for recycling and reuse.
There is anetwor kofreturnpoint sand dis-
ass embly plants which can recycle your vehi-
cle in an environmentally-responsibl eman-
ner. The options for recyclin gvehicles and
part sare constantly being developed and
improved. This means that your Mercedes-
Benz will als ocontinue to meet even the
inc reased recyclin gquotas in the future in
good time. You can obtain further information
from your national Mercedes -Ben zh omepage
or your national hotlin enumber. Vehicle equipment
This manual describes all the standard and
optional equipment of your vehicle available
at the time of publication of the Owner's Man-
ual. Country-specific differences are possi-
ble. Bear in mind that your vehicle may not
feature all functions described here. This also
refers to safety-related systems and func-
tions. The equipment in your vehicle may

Important safet
ynotes
Seat belts, together with belt tensioners, belt
forc elimiter sand airbags, are complemen-
tary, coordi nated restraint systems. They
reduce the risk of injur yinspecific ,pre-
define dtypes of accident situa tions and
thereby increase occupan tsafety. However,
seat belts and airbags generally do not pro-
tec tagainst objec tspenetratin gthe vehicle
from the outside.
To ensur ethat the restraint system scan
deliver their full potential protection, make
sure that:
R the seat and head restraint are adjusted
properly (Y page 92).
R the seat belt has been fastened properly
(Y page 41)
R the airbags can inflate unrestricted if
deployed (Y page 34)
R the steering wheel is adjusted properly
(Y page 92)
R the restraint systems have not been modi-
fied.
i An airbag increases the protection of
vehicle occupant swearing aseat belt. As
such they are only an additional restraint
system which complemen ts,b ut does not
replace, the seat belt. All vehicle occupants
must wear their seat belt correctly at all
times, even if the vehicle is equipped with
airbags. Airbags are not deployed in all
types of accidents, e.g. in situations where
airbag deployment would not increase the protection afforded by
acorrectly worn
seat belt. Airbag deployment only provides
increased protection if the seat belt is worn
correctly, because:
R the seat belt helps to keep the vehicle
occupan tinthe best position in relation
to the airbag
R for example, in ahead-on collision ,the
seat belt can mor eadequately 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
airba gisd eployed, it only provides protec-
tion in addition to the seat belt if the seat
belt is being worn correctly. G
Risk of accident and inju
ry
Always have maintenance work carried out at
aq ualified specialist workshop which has the
necessary specialist knowledg eand tool sto
carry out the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for thi spur-
pose.
In particular, work relevant to safety or on
safety-related systems must be carried out at
aq ualified specialist workshop .Ifthis wor kis
not carried out correctly, the operating safety
of your vehicl emay be affected. There is arisk
of an accident and injury. G
Risk of injury
The restrain tsystem may not work as inten-
ded if the following components have been
modified or work on thes ecomponents 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 coul dthen fail, e.g.
in the even tofanaccident in which the decel-
eratio nforc ew ould normally be high enough
to trigger the systems, or they coul dbetrig- 32
