Protection of the environment
General notes
HEnvironmental 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 Ô of 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
HEnvironmental 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

GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
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.
! There is a risk of damage to the vehicle if:
R the vehicle makes contact with the
ground, e.g. on a high kerb or a loose
road surface
R you drive too quickly over an obstacle,
e.g. a kerb or a pothole
R a heavy object hits the underbody or
chassis component
In these or similar situations, the vehicle
body, the underbody, chassis components,
wheels or tyres could be damaged even if
this is not visible. Components that have
been damaged in this way can unexpect-
edly fail or no longer be able to assimilate
the loads occurring in the event of an acci-
dent.
If the underbody panelling is damaged,
flammable material, such as leaves, grass
or twigs, could collect between the under-
body and underbody panelling. These
materials could ignite if they remain in con-
tact with hot components of the exhaust
system for an extended period.
Have the vehicle checked and repaired
immediately at a qualified specialist work-
shop. If you become aware when continu-
ing the journey that driving safety has been
effected, stop as soon as possible in
accordance with the traffic conditions. In
such cases, consult 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.
GWARNING
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.
Introduction23ZProCarManuals.com

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 processesRwarranties
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.

OFF indicator lamp must be continuously
lit.
If the front-passenger seat of your vehicle
does not have automatic child seat recog-
nition, or your rearward-facing child
restraint system does not have a trans-
ponder for automatic child seat recogni-
tion, children must be secured in a child
restraint system on a suitable seat in the
rear. 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, e.g. 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.GWARNING
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.GWARNING
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.
GWARNING
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 occupant.
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 there
is 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 6 SRS warn-
ing lamp lights up.
The airbag installation locations are identified
by the AIRBAG symbol.
i After an airbag has been deployed, have
the vehicle towed to the nearest qualified
specialist workshop, even if your vehicle
can still be driven.
Occupant safety43SafetyZProCarManuals.com

Windowbags are deployed:
R at the start of an accident with a high rate
of lateral vehicle deceleration or accelera-
tion, e.g. in a side impact
R on the side on which an impact occurs
R on the driver's and the front passenger's
side if the vehicle overturns and the system
determines that deployment can offer addi-
tional protection to that provided by the
seat belt
R independently of the use of the seat belt
R regardless of whether the front-passenger
seat is occupied
R independently of the front airbags
PRE-SAFE ®
(anticipatory occupant
protection)
! Make sure that there are no objects in the
footwell or behind the seats when moving
the seat back. There is a risk that the seats
and/or the objects could be damaged.
PRE-SAFE ®
takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations. Although your vehicle is equipped
with a PRE-SAFE ®
system, the possibility of
injury in the event of an accident cannot be
ruled out.
Always adapt your driving style to suit the
prevailing road and weather conditions and
maintain a safe distance from the vehicle in
front. Drive carefully.
PRE-SAFE ®
intervenes:
R when BAS activates, e.g. in emergency
braking situations.
R when adaptive Brake Assist intervenes
powerfully on vehicles with DISTRONIC
PLUS.
R in critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely.
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R vehicles with the memory function: the
front-passenger seat is adjusted if it is in an
unfavourable position.
R if the vehicle skids, the panorama sliding
sunroof and the side windows are closed so
that only a small gap remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning. All settings made by
PRE-SAFE ®
can then be reversed.
If the seat belts are not released:XMove the backrest or seat back slightly, but
only when the vehicle is stationary.
Seat belt pretensioning is reduced and the
locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. More
information about seat-belt adjustment can
be found under "Seat-belt adjustment"
( Y page 48).
Seat belts
Important safety notes
GWARNING
A seat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, cannot provide the intended
level of protection. Under certain circumstan-
ces, this could cause severe or even fatal inju-
ries in the event of an accident.
Therefore, make sure that all occupants — in
particular, pregnant women — wear their seat
belts correctly at all times.
R The seat belt must fit snugly on your body
and must not be twisted.Therefore, avoid
wearing bulky clothing, e.g. a winter coat.
The shoulder section of the belt must be
routed across the centre of your shoulder

Belt tensioners, belt force limitersGWARNING
Pyrotechnic seat belt tensioners that have
been deployed are no longer operational and
are unable to perform their intended protec-
tive function. This poses an increased risk of
injury or even fatal injury.
Therefore, have pyrotechnic belt tensioners
which have been triggered immediately
replaced at a qualified specialist workshop.
! If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckle on the front-passenger seat.
Otherwise, the belt tensioner could be trig-
gered in the event of an accident.
i Vehicles with PRE-SAFE ®
: belt tensioners
that are triggered by an electric motor can
be deployed as often as desired and do not
need to be replaced.
The front seat belts and the outer seat belts
in the rear are equipped with belt tensioners
and belt force limiters.
The belt tensioners tighten the seat belts in
an accident, pulling them close against the
body.
Belt tensioners do not correct incorrect seat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
The belt tensioners can only be activated
when:
R the ignition is switched on
R the restraint systems are operational; see
" 6 SRS warning lamp"( Y page 41)
R the belt tongue is engaged in the buckle on
each of the front seat belts.
The belt tensioners on the outside seats in the
rear compartment are triggered independ-
ently of the lock status of the seat belts.
The belt tensioners are triggered depending
on the type and severity of an accident:
R if, in the event of a head-on or rear-end col-
lision the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of the impact
R if, in the event of a side impact, on the side
opposite the impact the vehicle deceler-
ates or accelerates rapidly in a lateral direc-
tion
R in certain situations where the vehicle over-
turns and the system determines that it can
provide additional protection
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 there
is 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 6 SRS warn-
ing lamp lights up.
If the seat belt is also fitted with a belt force
limiter and this is triggered, the force exerted
by the seat belt on the vehicle occupant is
reduced.
The belt force limiters on the front seats are
synchronised with the front airbags, which
take on a part of the deceleration force. This
results in the load being distributed over a
greater area.
Children in the vehicle
Child restraint systems
Important safety notes
GWARNING
To reduce the risk of serious or even fatal
injury to the child in the event of a sudden
change in direction, braking or an accident:
R Children less than 1.50 m tall and under
twelve years of age must always be secured
