Protection of the environment
General notes
H
Environmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
Our objectives are to use the natural resour-
ces which form the basis of our existence on
this planet sparingly and in a manner which
takes the requirements of both nature and
humanity into consideration.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally-responsible manner.
Energy consumption and the rate of engine,
transmission, brake and tyre wear depend on
the following factors:
R operating conditions of your vehicle
R your personal driving style
You can influence both factors. Therefore,
please bear the following in mind:
Operating conditions:
R observe the correct tyre pressure.
R do not carry any unnecessary weight in the
vehicle
R remove the roof rack once you no longer
need it.
R a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R all maintenance work should be carried out
at a qualified specialist workshop.
Personal driving style:
R drive carefully and maintain a safe distance
from the vehicle in front.
R avoid frequent, sudden acceleration and
braking.
R monitor the vehicle's energy consumption. H
Environmental note
Have defective high-voltage batteries dis-
posed of in an environmentally responsible
manner. Consult a qualified specialist work- shop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose.
Returning an end-of-life vehicle
EU countries only:
Mercedes-Benz will take back your old vehicle to dispose of it in an environmentally-responsible
manner in accordance with the European Union
(EU) End of Life Vehicles Directive.
There is a network of return points and disas-
sembly plants available. You can return your
vehicle to these plants free of charge. This
makes a valuable contribution to the recycling
process and the conservation of resources.
For further information on recycling old vehi-
cles, recovery and the terms of the policy, visit
the Mercedes-Benz homepage. Genuine Mercedes-Benz parts
H
Environmental note
Daimler AG also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. For these, the same war-
ranty applies as for new parts.
! Airbags and seat belt tensioners, as well as
control units and sensors for these restraint
systems, may be installed in the following
areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R dashboard
R instrument cluster
R centre 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 accessories retrofitted at a qualified
specialist workshop. Introduction
19 Z

You could jeopardise the operating safety of
your vehicle if you use parts, tyres 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
systems, e.g. the brake system. Only use genu- ine Mercedes-Benz parts or parts of equal qual-
ity. Only use tyres, wheels and accessories that
have been specifically approved for your vehi-
cle.
Mercedes-Benz tests genuine parts and conver-
sion parts and accessories that have been spe-
cifically approved for your vehicle for their reli-
ability, safety and suitability. Despite ongoing
market research, Mercedes-Benz is unable to
assess other parts. Mercedes-Benz therefore
accepts no responsibility for the use of such
parts in Mercedes-Benz vehicles, even if they
have been officially approved or independently
approved by a testing centre.
In Germany, certain parts are only officially
approved for installation or modification if they
comply with legal requirements. This also
applies to some other countries. All genuine
Mercedes-Benz parts meet the approval
requirements. The use of non-approved parts
may invalidate the vehicle's general operating
permit.
This is the case:
R if they cause a change of the vehicle type from
that for which the vehicle's general operating
permit was granted
R if other road users could be endangered
R if the noise levels are adversely affected
Always specify the vehicle identification number (VIN) (Y page 281) when ordering genuine
Mercedes-Benz parts. Owner's Manual
Vehicle equipment
This Owner's Manual describes all models and
all standard and optional equipment available
for your vehicle at the time of publication of the
Owner's Manual. Country-specific differences
are possible. Note that your vehicle may not be
fitted with all features described. This is also the case for systems and functions relevant to
safety. Therefore, the equipment on your vehiclemay differ from that in the descriptions and
illustrations. The original purchase contract documentation
for your vehicle contains a list of all of the sys-
tems in your vehicle.
Should you have any questions concerning
equipment and operation, please consult a
Mercedes-Benz Service Centre.
The Owner's Manual and Service Booklet are
important documents and should kept in the
vehicle. Operating safety
Important safety notes
Important safety notes G
WARNING
If you do not have the prescribed service/
maintenance work or necessary repairs car-
ried out, this could result in malfunctions or
system failures. There is a risk of an accident.
Always have the prescribed service/mainte-
nance work as well as necessary repairs car-
ried out at a qualified specialist workshop. G
WARNING
Modifications to electronic components, their software as well as wiring could affect their
function and/or the operation of other net-
worked components. This could in particular
also be the case for systems relevant to
safety. They might not function properly any-
more and/or jeopardise the operational
safety of the vehicle. There is an increased
risk of an accident and injury.
Do not attempt to modify the wiring as well as
electronic components or their software.
Always have work on electrical and electronic components carried out at a qualified special-
ist workshop.
! There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
kerb or an unpaved road
R you drive too fast over an obstacle, e.g. a
kerb or a pothole in the road
R a heavy object strikes the underbody or
