Protecting the environment
General notes
H Environmental 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: 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
always make sure that the tire pressures
are correct. R
do not carry any unnecessary weight. R
remove roof racks once you no longer need
them. R
a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals. R
always have service work carried out at a
qualified specialist workshop.
Personal driving style: R
do not depress the accelerator pedal when
starting the engine. R
do not warm up the engine when the vehicle
is stationary. R
drive carefully and maintain a safe distance
from the vehicle in front. R
avoid frequent, sudden acceleration and
braking. R
change 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 that
have been specifically approved for your vehi-
cle.
Genuine Mercedes-Benz parts are subject to
strict quality control. Every part has been spe-
cifically developed, manufactured or selected
for and adapted to Mercedes-Benz vehicles.
Therefore, only genuine Mercedes-Benz parts
should be used.
More than 300,000 different genuine
Mercedes-Benz parts are available for
Mercedes-Benz models.
All authorized Mercedes-Benz Centers maintain
a supply of genuine Mercedes-Benz parts for
necessary 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-Benz
parts ( Y
page 322).
