Environmental protection
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 end-of-life
vehicle for environmentally-friendly disposal in
accordance with the European Union (EU) End-
Of-Life Vehicles Directive.
A network of vehicle take-back points and dis-
mantlers has been established for you to return
your vehicle. You can leave it at any of these
points free of charge. This makes an important
contribution to closing the recycling circle and
conserving resources.
For further information about the recycling and
disposal of end-of-life vehicles, and the take-
back conditions, please visit the national
Mercedes-Benz website for your country. 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. 26
Introduction

Have accessories retrofitted at a qualified
specialist workshop.
You could jeopardise the operating safety of
your vehicle if you use parts, tyres and wheels as
well as accessories relevant to safety that have not been approved by Mercedes-Benz. This
could lead to malfunctions in safety-relevant
systems, e.g. the brake system. Use only genu-
ine Mercedes-Benz parts or parts of equal qual- ity. Use only 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 officially approved for installation or modification only if they com-
ply 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 380) 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 the systems 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 be 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. Introduction
27 Z

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.
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, a speed bump 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
to.
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 on continuing your jour-
ney you notice that driving safety is impaired,pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult a qualified spe-
cialist workshop. Declarations of conformity

Diagnostics connection
The diagnostics connection is used for connect- ing diagnostic equipment at a qualified special-
ist workshop. G
WARNING
If you connect equipment to a diagnostics
connection in the vehicle, it may affect the
operation of vehicle systems. As a result, the operating safety of the vehicle could be affec-
ted. There is a risk of an accident.
Only connect equipment to a diagnostics con-
nection in the vehicle, which is approved for
your vehicle by Mercedes-Benz. 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. 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

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
Many of the electronic components in your vehi-
cle can store data.
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.
This includes, for example:
R operating conditions of system components,
e.g. fluid levels
R status messages concerning the vehicle and
its individual components, e.g. number of
wheel revolutions/speed, deceleration in
movement, 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
These data are 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 information is read out by employees of the service network (including the manufacturer)
using special diagnostic testers. You can obtain more information there, if required. Introduction

strap must be routed forwards and down-
wards from the vehicle belt sash guide. If nec-
essary, adjust the vehicle belt sash guide andthe front-passenger seat accordingly. Always
observe the information about suitable posi-
tioning of the child restraint system in this
Owner's Manual as well as the child restraint
system manufacturer's installation instruc-
tions.
Always observe the vehicle-specific information
for the correct positioning of the child restraint
system (Y page 62).
If the automatic front-passenger front airbag
deactivation system detects that:
R the front-passenger seat is unoccupied, the
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and
remains lit. This indicates that the front-
passenger front airbag is disabled.
R the front-passenger seat is occupied by a
child in a rearward-facing child restraint sys-
tem, the PASSENGER AIR BAG OFF indicator
lamp lights up after the system self-test and
remains lit. This indicates that the front-
passenger front airbag is disabled.
But in the case of a child in a rearward-facing
child restraint system, the PASSENGER AIR
BAG OFF indicator lamp can also go out after
the system self-test. This indicates that the
front-passenger front airbag is enabled. The
result of the classification is dependent on,
among other factors, the child restraint sys-
tem and the child's stature. It is recommen-
ded that you fit the child restraint system to a
suitable rear seat.
R the front-passenger seat is occupied by a
child in a forward-facing child restraint sys-
tem, either the PASSENGER AIR BAG OFF
indicator lamp lights up and remains lit after
the system self-test depending on the result
of the classification, or it goes out. The result of the classification is dependent on, among
other factors, the child restraint system and
the child's stature.
Move the front-passenger seat as far back as
possible. Always observe the information in
"Child restraint systems on the front-
passenger seat" (Y page 61) and in "Suita-
ble positioning of the child restraint system"
(Y page 62). Alternatively, you can fit the
child restraint system to a suitable rear seat. R
the front-passenger seat is occupied by a per-
son of smaller stature (e.g. a teenager or
small adult), the PASSENGER AIR BAG OFF
indicator lamp lights up and remains lit after
the system self-test depending on the result
of the classification or, alternatively, goes out.
- If the PASSENGER AIR BAG OFF indicator
lamp is off, move the front-passenger seat
as far back as possible. Alternatively, a per-
son with a small stature can sit on a rear
seat.
- If the PASSENGER AIR BAG OFF indicator
lamp is lit, a person with a smaller stature
should not use the front-passenger seat.
R the front-passenger seat is occupied by an
adult or a person with the stature of an adult,
the PASSENGER AIR BAG OFF indicator lamp
goes out after the system self-test. This indi-
cates that the front-passenger front airbag is enabled.
If children are travelling in the vehicle, be sure to
observe the notes on "Children in the vehicle"
(Y page 57).
If the automatic front-passenger front airbag
deactivation system is malfunctioning, the red
6 restraint system warning lamp on the
instrument cluster and the PASSENGER AIR
BAG OFF indicator lamp light up simultaneously.
The front-passenger front airbag is disabled in
this case and does not deploy during an acci-
dent. Have the automatic front-passenger front
airbag deactivation system checked and
repaired immediately at a qualified specialist
workshop. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for this purpose.
If the front-passenger seat, the seat cover or the
seat cushion are damaged, have the necessary
repair work carried out at a qualified specialist
workshop. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for this purpose.
For safety reasons, Mercedes-Benz recom-
mends that you use only a child restraint systemthat has been tested and approved by
Mercedes-Benz in combination with the auto-
matic front-passenger front airbag deactivation
system. 52
