Protecting the environment
General notes
HEnvironmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
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 environmen-
tally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected
by these factors:
Roperating conditions of your 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 con-
sumption.
Ralways make sure that the tire pressures
are correct.
Rdo not carry any unnecessary weight.
Rremove roof racks once you no longer need
them.
Ra regularly 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
starting the engine.
Rdo not warm up the engine when the vehicle
is stationary.
Rdrive carefully and maintain a safe distance
from the vehicle in front.
Ravoid frequent, sudden acceleration and
braking.
Rchange gear in good time and use each gear
only up to

systems, e.g. the brake system. Use only genu-ine Mercedes-Benz parts or parts of equal qual-ity. Only use tires, wheels and accessories thathave been specifically approved for your vehi-cle.
Genuine Mercedes-Benz parts are subject tostrict quality control. Every part has been spe-cifically developed, manufactured or selectedfor and adapted to Mercedes-Benz vehicles.Therefore, only genuine Mercedes-Benz partsshould be used.
More than 300,000 different genuineMercedes-Benz parts are available forMercedes-Benz models.
All authorized Mercedes-Benz Centers maintaina supply of genuine Mercedes-Benz parts fornecessary service and repair work. In addition,strategically located parts delivery centers pro-vide quick and reliable parts service.
Always specify the vehicle identification number(VIN) when ordering genuine Mercedes-Benzparts (Ypage 318).
