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

Information on driving
Check the tyre pressures when the vehicle is
heavily laden and, if necessary, adjust.
While driving, pay attention to vibrations,
noises and unusual handling charac teristics,
e.g .pulling to one side .This ma yindicate that
the wheels or tyres are damaged. If you sus-
pect that atyre is defective, reduce your
speed immediately. Stop the vehicle as soon
as possibl etocheckthe wheels and tyres for
damage. Hidden tyr edamage could also be
causing the unusual handling characteristics.
If you find no signs of damage, have the tyres
and wheel schecked at aqualified specialist
workshop.
When parking your vehicle, make sure that
the tyres do not get deformed by the kerb or 396
