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

possible to the maximum permissible nose-
weight. Do not use anoseweight of less than 50kg, otherwise the trailer ma
ycome
loose.
Not ethat the payload and the rea raxle load
are reduce dbythe actual payload.
i Chec kthe tyr epressures when towin ga
trailer. You will find the values in the tyre
pressure table in the fuel filler flap of the
vehicle (Y page 399).
You will find installation dimensions and loads
in the "Technical data" section
(Y page 432).
The maximum permissible trailer drawbar
noseweight on the ball coupling is 140 kg.

erwise damage the tyres and cause an acci-
dent.
! Always maintain adistance of at least
30 cm between the vehicle and the high-
pressure cleaner nozzle. Information about
the correc tdistanc eisavailable from the
equipment manufacturer.
Move the high-pressure cleane rnozzle
around when cleanin gyour vehicle.
Do not aim directly at any of the following:
R tyres
R door gaps, roof gaps, join tsetc.
R electrical components
R battery
R connectors
R lights
R seals
R trim elements
R ven tilation slots
Damaged seals or electrical components
can lead to leaks or failures.
Cleanin gthe paintwork !
Do not affix:
R stickers
R films
R magnetic plate sorsimilar items
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit aqualified spe-
cialist workshop. X
Remove impurities immediately, where
possible, whils tavoiding rubbing to ohard.
X Soak insect remains with insect remover
and rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse
off the treated areas afterwards.
X Remove coolant, brake fluid, tree resin,
oils, fuels and greases by rubbing gently
with acloth soaked in petroleum ether or
lighter fluid.
X Use tar remover to remov etar stains.
X Use silicone remover to remove wax.
Care and treatment of mat tpaintwork !
Never polis hthe vehicle or the light alloy
wheels. Polishin gmakes the paintwork
shiny.
! The following may cause the paint to
become shiny and thus reduce the matt
effect:
R Vigorous rubbing with unsuitable mate-
rials.
R Frequent use of car washes.
R Washing the vehicle in direct sunlight.
! Never use paint cleaner, buffing or pol-
ishing products, or glos spreserver, e.g.
wax .These product sare onl ysuitable for
high-glos ssurfaces. Thei ruse on vehicles
wit hm att finish leads to considerable sur-
face damage (shiny, spotted areas).
Always have paintwork repairs performed
at aq ualified specialist workshop, e.g. a
Mercedes-Ben zService Centre.
! Do not use wash programs with ahot wax
treatmen tunder any circumstances.
Observe thes enotes if your vehicle has a
clea rmatt finish. This will help you to avoid
damage to the paintwork due to incorrect
treatment.
Thes enotes also apply to light-alloy wheels
with aclear matt finish. 368
