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-respon-sible manner in accordance with the Euro-
pean Union (EU) End of Life Vehicles Direc-
tive.
There is a network of return points and dis-
assembly 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 22
Introduction

Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint sys-
tems.
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
which have not been approved by Mercedes- Benz. This could lead to malfunctions in
safety-relevant systems, e.g. the brake sys-
tem. Only use genuine Mercedes-Benz parts
or parts of equal quality. Only use tyres,
wheels and accessories that have been spe-
cifically approved for your vehicle.
Mercedes-Benz tests genuine parts and con-
version parts and accessories that have been
specifically approved for your vehicle for their reliability, 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 gen- uine 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 num- ber (VIN) (Y page 396) when ordering genu-
ine 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 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 documenta-
tion for your vehicle contains a list of all of 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 kept in the
vehicle. Operating safety

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 res-
cue card contains, in a compact form, the
most important information about your vehi-
cle, e.g. the routing of the electric cables.
You can find more information under http:// portal.aftersales.i.daimler.com/public/

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 compo-
nents, e.g. fluid levels
R the vehicle's status messages and those of
its individual components, e.g. number of
wheel revolutions/speed, deceleration in
movement, lateral acceleration, accelera-
tor pedal position
R malfunctions and defects in important sys-
tem components, e.g. lights, brakes
R vehicle reactions and operating conditions
in special driving situations, e.g. airbag
deployment, intervention of stability con-
trol systems
R ambient conditions, e.g. outside tempera-
ture
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 mem- ory 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
service network (including the manufacturer)
using special diagnostic testers. You can
obtain more information there, if required.
After a fault has been rectified, the informa-
tion is deleted from the fault memory or is
continually overwritten.
When operating the vehicle, situations are
conceivable in which this technical data, in

In the event of a side impact, the sidebag is
deployed on the side on which the impact
occurs.
Vehicles with the automatic front-passenger
airbag deactivation system: the sidebag on
the front-passenger side deploys under the
following conditions:
R an occupant is detected on the front-
passenger seat or
R the belt tongue is engaged in the belt
buckle of the front-passenger seat
If the belt tongue is engaged in the belt
buckle, the sidebag on the front-passenger
side deploys if an appropriate accident situa- tion occurs. In this case, deployment is inde- pendent of whether the front-passenger seat
is occupied or not.
Windowbags Windowbags
:are integrated into the side
of the roof frame and deploy in the area from
the A-pillar to the C-pillar.
When deployed, the windowbag enhances the level of protection for the head. However, it
does not protect the chest or arms.
In the event of a side impact, the windowbag
is deployed on the side on which the impact
occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a windowbag may be deployed in
other accident situations (Y page 55). Automatic front-passenger front air-
bag deactivation
Introduction In order to recognise a child restraint system
on the front-passenger seat, the automatic
front-passenger front airbag deactivation sys- tem categorises the person in the front-
passenger seat. Depending on that result, the
front-passenger front airbag is either enabled or disabled. If a rearward-facing child
restraint system is fitted to the front-
passenger seat, the PASSENGER AIR BAG
OFF indicator lamp must light up after the
system self-test and remain lit. The front-
passenger front airbag is disabled.
The system does not disable:
R the sidebag
R the windowbag
R the seat belt tensioner
Make sure that your vehicle is equipped with
the automatic front-passenger front airbag
deactivation system (Y page 61). If this is
not the case, always install a child restraint
system on a suitable rear seat (Y page 62).
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
be sure to observe the correct positioning of
the child restraint system. Never place
objects under or behind the child restraint
system, e.g. a cushion. Fully retract the seat
cushion length. The entire base of the child
restraint system must always rest on the seat
cushion of the front-passenger seat. The
backrest of the forward-facing child restraint system must, as far as possible, be resting onthe backrest of the front-passenger seat. The
child restraint system must not touch the roof or be put under strain by the head restraint.
Adjust the angle of the seat backrest and the
head restraint position accordingly. Only then is the correct function of the automatic front- passenger front airbag deactivation system
guaranteed. Always observe the information
on suitable positioning of the child restraint
system (Y page 62) in addition to the child Occupant safety
