General notes
HEnvironmental note
Daimler's declared policy is one of

The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and inamanner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an
environmentally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected
by these factors:
Roperating conditionsofyour vehicle
Ryour personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
Ravoid short trips as these increase fuel
consumption.
Ralways make sure that the tire pressures
are correct.
Rdo not carry any unnecessary weight.
Rremove roof racks once you no longer need
them.
Raregularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
Ralways have service work carried out at a
qualified specialist workshop.
Personal driving style:
Rdo not depress the accelerator pedal when
startingthe engine.
Rdo not warm up the engine when the vehicle
is stationary.
Rdrive carefully and maintainasafe distance
from the vehicle in front.
Ravoid frequent, sudden acceleration and
braking.
Rchange gear in good time and use each gear
only up toof its maximum engine speed.
Rswitch off the engine in stationary traffic.
Rkeep an eye on the vehicle's fuel
consumption.
Environmental concerns and
recommendations
Wherever the operating instructions require
you to dispose of materials, first try to
regenerate or re-use them. Observe the
relevant environmental rules and regulations
when disposing of materials. In this way you
will help to protect the environment.
Product information

genuine Mercedes-Benz parts, conversion
parts and accessories that have been
approved for your vehicle.
Mercedes-Benz tests genuine parts as well as
conversion 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
vehicles. This is also the case, even if they
have been independently or officially
approved. The use of non-approved parts
could affect your vehicle's operating safety.
Genuine Mercedes-Benz parts, approved
conversion parts and accessories are
available from any authorized Mercedes-Benz
Center. Here, you will receive advice about
permissible technical modifications, and the
parts will be professionally installed.
