Protection of th
eenvironment Genera
lnotes H
Environmental note
Daimler's declared policy is one of compre-
hensive 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 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 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 carr yany 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 service work carried out at a
qualified specialist workshop.
Personal drivin gstyle:
R do not depres sthe accelerator pedal when
startin gthe engine.
R do not war mupthe engin ewith 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 Ôof its maximum engine speed.
R switch off the engine in stationary traffic. Returning an end-of-life vehicle
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 with agros svehicle weight of up to
3. 5t ,ina ccordance 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 anetwor kofreturnpoint sand dis-
assembly plants which can recycle your vehi-
cle in an environmentally-responsible man-
ner. The methods employed in vehicl eand
parts recycling are constantly being devel-
ope dand improved .This means that your
Mercedes-Benz will also con tinue to meet
even the increased recycling quotas in the
future in goo dtime. You can obtain further
information from your national Mercedes-
Benz homepage or your national hotline num-
ber. Product informa
tion
Mercedes-Benz recommends that you use
genuine Mercedes-Benz parts, conversion
parts and accessories that have been
approved for the type of vehicle.
Mercedes-Benz tests genuine parts and con-
version parts and accessories that have been
specifically approved for your vehicle for their
reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to assess other parts. Therefore,
Mercedes-Benz accepts no responsibility for
the use of such parts in Mercedes-Benz vehi- Introduction

WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available with limitations, or not at all
.This coul daffect,
for example, the powe rsteering and the brake
boosting effect .You will require considerably
mor eeffort to steer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving.
Drive sensibly –save fuel Observe the fol
lowing tips to save fuel:
X The tyres should always be inflated to the
recomm ended tyr epressure.
X Remove unnecessary lo ads.
X Remov eroof carriers when they are not
needed.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X observe the service intervals in the Service
Booklet or in the service interval display.
Have all the maintenan cework carried in
accordanc ewith Daimler AG regulations.
Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic and in
hilly terrain. Short journeys
! Vehicles with adiesel particle filter: if
the vehicle is mostly driven for short dis-
tances, it is possible that malfunctions may
occur durin gthe automa ticc leaning of the
diesel particle filter. This may lead to fuel
collectin ginthe engin eoil and cause
engin efailure. Therefore, if you frequently
drive short distances, you should tak ea20

! Only refuel using supe runleaded petrol

! Premium-grade unleaded petro lwith an
octane ratin gof95R ON/85 MON ma ybe
used as atemporar ymeasur eifthe recom-
mended fuel is not available. This may
reduce engin eperforman ceand increase
fuel consumption .Asmuch as possible,
avoid driving at full throttle.
! Regular unleade dpetrol with an octane
rating of 91 RON/82.5 MON may also be
used as atemporary measure if the recom-
mended fuel is not available.
Doing so result sinnoticeably higher fuel
consumption ,and the engine power output
is noticeably reduced .Avoi dd riving at full
throt tle.
If only regular unleaded petrol with an
octane ratingof91R ON/82.5 MO Nor
lowe risa vailable ,you must have the vehi-
cle adapted to this fuel at aqualified spe-
cialist workshop.
i E10 fuel contains up to 10% bioethanol.
Your vehicle is suitabl efor use with E10
fuel. You can refuel your vehicle using E10
fuel.
Additives
! Operatin gthe engin ewith fuel additives
can cause wear in the fuel high-pressure
pump and contaminate the entire fuel sys-
tem. The repair costs are high. This does
not include additives for the removal and
prevention of residue build-up. Petrol must
only be mixed with additives recommended
by Mercedes-Benz .More information about
recommended additives can be obtained
from any Mercedes-Benz Servic eCentre. One of the major problem
swith low-grade
fuel is the creation of carbon deposits during
the process of burnin gfuel. Mercedes-Benz
recommends that you use fuel brands that
have additives.
If you use fuels without these additives for a
longer period of time, there may be abuild-up
of carbon deposits. Thes ewill form especially
on the inlet valves and in the combustion
chamber.
This could lead to engine runnin gproblems,
e.g.:
R longe rengine warm-up phase
R uneven idle
R engine noise
R misfiring
R los so fpower
In areas where petrol with the required addi-
tives is not available, carbon deposits can
build up. In this case, Mercedes-Benz recom-
mends the use of additives that have been
approved for Mercedes-Benz vehicles; see
http:/ /bevo.mer cedes-benz.com.
The quality of the fuel available in some coun-
tries may not be sufficien t.Residue could
build up as aresult. In such cases, and in
consultation with aMercedes-Ben zService
Cent re,the petrol ma ybemixed with the
additive recommended by Mercedes-Benz
(part no. A000989254510). You must
observe the notes and mixin gratios specified
on the container.
Consult aMercedes-Ben zService Cent reto
view alist of approved products. Observe the
instruc tions for use in the product descrip-
tion.
Do not mix other fuel additives with fuel. This
causes unnecessary cost sand could damage
the engi ne. Service products and capacities
