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 Ôof its maximum engine speed.
Rswitch off the engine in stationary traffic.
Rkeep an eye on the vehicle's fuel consump-
tion.
Environmental concerns and recom-
mendations
Wherever the Operator's Manual requires you to
dispose of materials, first try to regenerate or re-
use them. Observe the relevant environmental
rules and regulations when disposing of materi-
als. In this way you will help to protect the envi-
ronment.
Genuine Mercedes-Benz parts
HEnvironmental note
Daimler AG also supplies reconditioned major
assemblies and parts which are of the same
quality as new parts. They are covered by the
same Limited Warranty entitlements as new
parts.
!Air bags and Emergency Tensioning Devi-
ces, as well as control units and sensors for
these restraint systems, may be installed in
the following areas of your vehicle:
Rdoors
Rdoor pillars
Rdoor sills
Rseats
Rcockpit
Rinstrument cluster
Rcenter console
Do not install accessories such as audio sys-
tems in these areas. Do not carry out repairs or welding. You could impair the operating
efficiency of the restraint systems.
Have aftermarket accessories installed at a
qualified specialist workshop.
You could jeopardize the operating safety of
your vehicle if you use parts, tires and wheels as
well as accessories relevant to safety which
have not been approved by Mercedes-Benz. This
could lead to malfunctions in safety-relevant
