Protection of the environment
15Protection of the environment
H
Environmental note
Daimler's declared policy is one of integra-
ted environmental protection.
Our objectives are to use the natural
resources which form the basis of our exis-
tenceont his planet sparingly and in aman-
ner which takes the requirements of both
nature and humanity into consideration.
You too can help to protect the environ-
ment by operating your vehicle in an envi-
ronmentally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tyre wear depend
on the following factors:
R Operating condition sofyour vehicle
R Your personal driving style
You can influence both factors.
Therefore, please bear the following in
mind:
Operating conditions
R Avoid short trips as these increase fuel
consumption.
R Make sure that the tyre pressures are
always correct. R
Do not carry any unnecessary weight in
the vehicle.
R Keep an eye on the vehicle's fuel con-
sumption.
R Remove roof racks once you no longer
need them.
R Ar egularly serviced vehicle will contrib-
ute to environmental protection. You
should therefore adhere to the service
intervals.
R Always have maintenance work carried
out at aqualified specialist workshop,
e.g. aMercedes-Benz Service Centre.
Personal driving style
R Do not depress the accelerator pedal
when startingt he engine.
R Do not warm up the engine when the
vehicle is stationary.
R Drive carefully and maintain asafe dis-
tancef rom the vehicle in front.
R Avoid frequent, sudden acceleration.
R Change gear in good time and only use
each gear for up to 2
/ 3 of its maximum
engine speed.
R Switch off the engine in stationary traffic. Returning used vehicles
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 appliesto
vehicles of up to 3.5 tgross vehicle weight, in
accordanc ewith national regulations. For
several years, Mercedes-Benz has been
meeting all the legal requirements for a
design which allowsf or recycling and re-use.
There is anetwork of return points and dis-
assembly plants which can recycle your vehi-
cle in an environmentally-responsible man-
ner. The options for recycling vehicles and
parts are constantly being developed and
improved. This means that your Mercedes-
Benz will also continue to meet even the
increased recycling quotas in the future in
good time. You can obtain further information
from your national Mercedes-Benz homepage
or your national hotline number. Introduction

Environmental note
Avoid driving at high engin espeeds, as this
increases your vehicle's consumption
unnecessarily and pollutes the environ-
ment through increased emissions. Outsid

Risk of accident
The road surface may be icy, especially in
wooded areas or on bridges, even if tem-
peratures are just above freezing point .The
vehicle could skid if you fail to adapt your
driving style. You should therefore always
adapt your driving style and speed to suit
the weather conditions.

The vehicle will use more fuel than usual in
the following situations:
R at very low temperatures
R in urban traffic
R on short trips
R in mountainous terrain
The consumption figures have been deter-
mined according to EU Directive
