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 Introduction

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 effect 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.
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 visi-
ble. Components damaged in this way can
unexpectedly fail or, in the case of an acci-
dent, no longer withstand the strain they
are designed for. If the underbody panelling is damaged,
combustible 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 specialist workshop. If, upon con-
tinuing your journey, you notice that driving
safety is impaired, pull over and stop the
vehicle immediately, paying attention to
road and traffic conditions. In such cases,
visit a qualified specialist workshop. Declarations of conformity
Wireless vehicle components The following information applies to all com-
ponents of the vehicle and the information
systems and communication devices integra-
ted 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 rel-
evant conditions of Directive 1999/5/EC.
You can obtain further information from any
Mercedes-Benz Service Centre.
Electromagnetic compatibility The electromagnetic compatibility of the vehi-
cle components has been checked and certi- fied according to the currently valid version of Regulation ECE-R 10. Diagnostics connection
The diagnostics connection is only intended
for the connection of diagnostic equipment at a qualified specialist workshop. Introduction

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 contraventions against these
instructions are not covered either by
Mercedes-Benz implied warranty or by the
New or Used-Vehicle Warranty. 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 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 recognising 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
It is read by employees of the service network (including manufacturers) using special diag-
nostic testers. More detailed information is
obtained from it, 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
connection with other information (if neces-
sary, under 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
contractually agreed upon with the customer
allow certain vehicle data to be conveyed by
the vehicle as well. The additional functions
include, for example, vehicle location in case of an emergency. Introduction

passenger seat. The
4PASSENGER
AIRBAG OFF indicator lamp must be con-
tinuously lit.
If you secure a forward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible.
R make sure there are no heavy or sharp-
edged objects in the pockets of clothing.
R do not lean forwards, e.g. over the cover of
the driver's/front-passenger front airbag,
particularly when the vehicle is in motion.
R do not put your feet on the dashboard.
R only hold the steering wheel on the outside.
This allows the airbag to be fully deployed.
You could be injured if the airbag is
deployed and you are holding the inside of
the steering wheel.
R do not lean on the doors from inside the
vehicle.
R make sure that there are no people, ani-
mals or objects between the vehicle occu-
pants and the area where the airbags are
deployed.
R do not place any objects between the seat
backrest and the door.
R do not hang any hard objects, for example,
coat hangers, on the grab handles or coat
hooks.
R do not attach accessories, e.g. cup holders,
to the doors.
It is not possible to rule out a risk of injury
being caused by an airbag, due to the high
speed at which the airbag must be deployed. G
WARNING
If you modify the airbag covers or affix
objects, e.g. stickers to them, the airbags may
no longer function as intended. There is an
increased risk of injury.
Never modify the airbag covers and do not
affix any objects to them.
The airbag installation locations are identified
by the AIRBAG symbol. G
WARNING
Unsuitable seat covers may obstruct or even
prevent deployment of the airbags integrated into the seats. The airbags may then fail to
protect the vehicle occupants as intended.
Operation of the automatic child seat recog-
nition may also be impaired. There is an
increased risk of injury, possibly even fatal.
Use only seat covers which have been specif-
ically approved for the respective seat by
Mercedes-Benz.
You should only use seat covers that have
been approved for your vehicle by Mercedes-
Benz. The seat covers must have a special
tear seam for sidebags. Otherwise, the side-
bags cannot deploy correctly and therefore
cannot provide the intended protection in the event of an accident. G
WARNING
After the driver's airbag has been deployed,
the airbag parts are hot. There is a risk of
injury.
Do not touch the airbag parts. Have deployed airbags replaced immediately at a qualified
specialist workshop.
Airbag deployment slows down and restricts
the movement of the vehicle occupants.
If the airbags are deployed, you will hear a
bang, and a small amount of powder may also be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard and does not indicate that thereis a fire in the vehicle. The powder may cause
short-term breathing difficulties to persons
suffering from asthma or other pulmonary
conditions. In order to prevent potential
breathing difficulties, you should leave the
vehicle as soon as it is safe to do so. You can also open the window to allow fresh air to
enter the vehicle interior. The 6SRS warn-
ing lamp lights up.
i After an airbag has been deployed, have
the vehicle towed to the nearest qualified Occupant safety
53Safety Z

Have roll bars checked immediately at a quali-
fied specialist workshop. G
WARNING
If you place objects or clothing on the roll bar covers, these could impair roll bar extension.
The roll bars may then not protect the vehicle occupants as intended. In addition, objects
could endanger the vehicle occupants when
the roll bar is extending. This poses an
increased risk of injury or even fatal injury.
Ensure that the movement area of the roll bar covers is kept clear. Always stow all objects in
the vehicle correctly. The roll bars are located in the rear area of the
vehicle under the two outer rear compart-
ment trim covers.
The roll bars are extended automatically if
systems detect that the vehicle is in danger of
overturning. The two rear compartment trim
covers are opened and the roll bars are exten- ded within fractions of a second.
Once the roll bars are extended, you can no
longer lower them. An open roof can no lon-
ger be closed. In this case, visit the nearest
qualified specialist workshop. PRE-SAFE

R in critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely
R on vehicles with DISTRONIC PLUS: if
BAS PLUS brakes hard or the radar sensor
system detects an imminent danger of col- lision in certain situations
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the seat belts are pre-tensioned.
R if the vehicle skids, the side windows are
closed so that only a small gap remains.
R the front-passenger seat is adjusted if it is
in an unfavourable position.
R Vehicles with a multicontour seat or
active multicontour seat: the air pres-
sure in the side bolsters of the backrest is
increased.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pre-tensioning. All settings made by
PRE-SAFE ®
can then be reversed. 56
