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.
Fuel 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 avoid short trips, as these increase fuel
consumption.
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 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 Ôof its maximum engine speed.
R switch off the engine in stationary traffic.
R monitor the vehicle's fuel consumption. 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. 24
Genuine Mercedes-Benz partsIntroduction

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 emission or noise levels are adversely
affected
Always specify the vehicle identification number (VIN) (Y page 336) when ordering genuine
Mercedes-Benz parts. Owner's Manual
Vehicle equipment
i This Owner's Manual describes all models
and all standard and optional equipment
available for your vehicle at the time of pub-
lication of the Owner's Manual. Country-spe-
cific 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 vehicle may 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
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
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is a risk of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact 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. Operating safety
25Introduction
Z

Always have work on electrical and electronic
components carried out at a qualified special-ist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
! 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
parts of the chassis
In situations like this, the body, the under-
body, chassis parts, wheels or tyres could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the strain they are designed for.
If the underbody panelling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody panelling. If these materials
come in contact with hot parts of the exhaust
system, they can catch fire.
In such situations, have the vehicle checked
and repaired immediately at a qualified spe-
cialist workshop. If, upon continuing your
journey, you notice that driving safety is
impaired, pull over and stop the vehicle imme- diately, paying attention to road and traffic
conditions. In such cases, consult a qualified
specialist workshop. Declarations of conformity
Wireless vehicle components The following information applies to all compo-
nents of the vehicle and the information sys-
tems and communication devices integrated
into the vehicle which receive and/or transmit
radio waves:
The components of this vehicle that receive
and/or transmit radio waves are compliant with
the basic requirements and all other relevant
conditions of Directive 1999/5/EC. You can
obtain further information from any Mercedes-
Benz Service Centre. Electromagnetic compatibility The electromagnetic compatibility of the vehicle
components has been checked and certified
according to the currently valid version of Reg-
ulation ECE-R 10. Diagnostics connection
The diagnostics connection is only intended for the connection of diagnostic equipment at a
qualified specialist workshop. G
WARNING
If you connect equipment to a diagnostics
connection in the vehicle, it can affect the
operation of the vehicle systems. This may
affect the operating safety of the vehicle.
There is a risk of an accident.
Do not connect any equipment to a diagnos-
tics connection in the vehicle. G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor-mats on top of one another.
! If the engine is switched off and equipment
on the diagnostics connection is used, the
starter battery may discharge.
Connecting equipment to the diagnostics con-
nection can lead to emissions monitoring infor-
mation being reset, for example. This may lead
to the vehicle failing to meet the requirements of
the next emissions test during the main inspec- tion. 26
Operating safetyIntroduction

Qualified specialist workshop
A qualified specialist workshop has the neces-
sary special skills, tools and qualifications to
correctly carry out any necessary work on your
vehicle. This particularly applies to work rele-
vant to safety.
Observe the notes in the Service Booklet.
Always have the following work carried out at a
qualified specialist workshop:
R work relevant to safety
R service and maintenance work
R repair work
R modifications, installations and conversions
R work on electronic components
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre. Vehicle registration
Mercedes-Benz may ask its Service Centres to
carry out technical inspections on certain vehi-
cles. The quality or safety of the vehicle is
improved as a result of the inspection.
Mercedes-Benz can only inform you about vehi-
cle checks if it has your registration data.
It is possible that your vehicle has not yet been
registered in your name in the following cases:
R if your vehicle was not purchased at an
authorised specialist dealer.
R if your vehicle has not yet been examined at a
Mercedes-Benz Service Centre.
It is advisable to register your vehicle with a
Mercedes-Benz Service Centre.
Inform Mercedes-Benz as soon as possible
about any change in address or vehicle owner-
ship. You can do this at a Mercedes-Benz Ser-
vice Centre, for example. Correct use
If you remove any warning stickers, you or oth-
ers could fail to recognise certain dangers.
Leave warning stickers in position.
Observe the following information when driving your vehicle:
R the safety notes in this manual
R the vehicle technical data R
traffic rules and regulations
R laws and safety standards pertaining to motor
vehicles Implied warranty
! Follow the instructions in this manual about
the proper operation of your vehicle as well as
about possible vehicle damage. Damage to
your vehicle that arises from culpable contra- ventions against these instructions are not
covered either by Mercedes-Benz implied
warranty or by the New or Used-Vehicle War-
ranty. QR code for rescue card
The QR code is secured in the fuel filler flap and
on the opposite side on the B-pillar. In the event
of an accident, rescue services can use the QR
code to quickly find the appropriate rescue card for your vehicle. The current rescue card con-
tains, in a compact form, the most important
information about your vehicle, e.g. the routing
of the electric cables.
You can find more information under http://
portal.aftersales.i.daimler.com/public/
content/asportal/en/communication/
informationen_fuer/QRCode.html. Data stored in the vehicle
A wide range of electronic components in your
vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about:
R the vehicle's operating state
R events
R faults
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
These include, for example:
R operating conditions of system components,
e.g. fluid levels
R the vehicle's status messages and those of its
individual components, e.g. number of wheelrevolutions/speed, deceleration in move- Data stored in the vehicle

ment, lateral acceleration, accelerator pedal
position
R malfunctions and defects in important system
components, e.g. lights, brakes
R vehicle reactions and operating conditions in
special driving situations, e.g. airbag deploy-
ment, intervention of stability control sys-
tems
R ambient conditions, e.g. outside temperature
This data is of an exclusively technical nature
and can be used to:
R assist in detecting and rectifying faults and
defects
R analyse vehicle functions, e.g. after an acci-
dent
R optimise vehicle functions
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data memory and fault data memory.
Services include, for example:
R repair services
R service processes
R warranty events
R quality assurance
The vehicle is read out by employees of the ser- vice network (including the manufacturer) using
special diagnostic testers. You can obtain more
information there, if required.
After a fault has been rectified, the information
is deleted from the fault memory or is continu-
ally overwritten.
When operating the vehicle, situations are con-
ceivable in which this technical data, in connec- tion with other information (if necessary, after
consultation with an authorised expert), could
be traced to a person.
Examples include:
R accident reports
R damage to the vehicle
R witness statements
Further additional functions that have been con- tractually agreed upon with the customer allow
certain vehicle data to be conveyed by the vehi-
cle as well. The additional functions include, for example, vehicle location in case of an emer-
gency. Copyright information
