Protection of the environment
Notes
H
Environmental note
Daimler's declared policy is one of integrated
environmental protection.
The objectives are for the natural resources
which form the basis of our existence on this
planet to be used sparingly and in amanner
which takes the requirements of both nature
and humanity into account.
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 condition sofyour vehicle
R your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
R avoid short trips as these increase fuel con-
sumption.
R make sure that the tyre pressures are
always correct.
R do not carry any unnecessary weight.
R keep an eye on the vehicle's fuel consump-
tion.
R remove roof racks once you no longer need
them.
R ar egularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R always have maintenance work carried out
at aq ualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
Personal driving style:
R do not depress the accelerator pedal when
startingt he engine.
R do not warm up the engine with the vehicle
stationary. R
drive carefully and maintain asafe distance
from the vehicle in front.
R avoid frequent, sudden acceleration.
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. Returning end-of-life vehicles
Mercedes-Benz will take back your
Mercedes-Benz to dispose of it in an environ-
mentally responsible manner, in accordance
with the European Union (EU) End of Life
Vehicles Directive.
The End of Life Vehicles Directive applies to
vehicles with agross vehicle weight of up to
3.5 t, in accordance with national regulations.
For several years, Mercedes-Benz has been
meeting all the legal requirements for a
design which allowsf or recycling and reuse.
There is anetwork of return points and dis-
assembly plants which can recycle your vehi-
cle in an environmentally responsible man-
ner. The options for recycling vehicles and
parts are constantly being developed and
improved. This means that your Mercedes-
Benz will also continue to meet even the
increased recycling quotas in the future in
good time. You can obtain further information
from your national Mercedes-Benz homepage
or your national hotline number. Vehicle equipment

Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviation sare possible. Please

Important safet
ynotes
Seat belts, together wit hthe Supplemental
Restrain tSyste m–S RS (Y page 39), are
complementary, co-ordinated restrain tsys-
tems .They reduce the risk of injury in spe-
cific, pre-defined types of accident situations
and thereby increase occupant safety. How-
ever, seat belts and airbags generally do not
protect against objectsp enetratingthe vehi-
cle from the outside.
To ensure that the restraint systems can
deliver their full potential protection, make
sure that:
R the seat and head restraint are adjusted
properly (Y page 100).
R the seat belt has been fastened properly
(Y page 47).
R the airbags can inflate unrestricted if
deployed (Y page 40).
R the steering wheel is adjusted properly
(Y page 100).
R the restraint systems have not been modi-
fied.
i An airbag increases the protection of
vehicle occupants wearing aseat belt. As
such, they are only an additional restraint
system which complements, but does not
replace, the seat belt. All vehicle occupants must wear their seat belt correctly at all
times, even if the vehicle is equipped with
airbags. The airbags are not deployed in all
types of accidents. For example, if the pro-
tective capacity of correctly fastened seat
belts is not increased by deploying the air-
bags, the airbags will not deploy.A
irbag
deploymen tonly provides increased pro-
tection if the sea tbeltisw ornc orrectly
because:
R the sea tbelt helps to keep the vehicle
occupan tinthe best position in relation
to the airbag.
R in ah ead-on collision, for example, the
seat belt prevents the vehicle occupant
from being propelled towards the point
of impact. It can thus reduce the risk of
injury.
In accidents in which an airbag is deployed,
it provides increased protection only if the
seat belt is worn correctly. G
WARNING
If service work is not carried out correctly, the
operating safety of your vehicle may be affec-
ted. This could cause you to lose control of
your vehicle and cause an accident. More-
over, the safety systems may no longer be
able to protect you or others as they are
designed to do.
Always have service work carried out at a
qualified specialist workshop. The workshop
must have the necessary specialist knowl-
edge and tools to carry out the work required.
Mercedes-Ben zrecommends that you use a
Mercedes-Benz Service Centr efor this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop. 38

WARNING
Modifications to or work performe dincor-
rectly on the following parts can result in the
restraint systems not functioning as intended:
R the restraint system, consisting of seat
belts and their anchorage points, beltt en-
sioners, belt forc elimiters and airbags
R the wiring
R networked electronic systems
Airbags and belt tensioners could fail to
deploy or be triggered in an acciden tdespite
the deceleration forc ebeing sufficien ttotrig-
ger the systems, or could be triggered unin-
tentionally. For this reason, never make any
modifications to the restraint systems.
Therefore, you must not tamper with elec-
tronic components or their software. SRS (Supplemental Restraint System)
Introduction SRS consist
sof:
R the 6 SRS warning lamp
R airbags
R airbag control unit (with crash sensors)
R belt tensioners
R belt force limiters
SRS reduces the risk of occupant scoming
into contact with the vehicle's interior in the
event of an accident .Itcan also reduce the
effect of the forces to which occupant sare
subjected during an accident.
SRS warning lamp SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 6 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than afew seconds
after the engine is started. G
WARNING
If SRS is malfunctioning, individual systems
may be activated unintentionally or may not
be triggered in the event of an accident with
ah igh rate of vehicle deceleration.
Am alfunction has occurred if:
R the 6 SRS warning lamp does not light
up when the ignition is switched on.
R the engine is runnin gand the 6SRS
warning lamp does not go out after afew
seconds.
R the engine is runnin gand the 6SRS
warning lamp lights up again.
In this case, have SRS checked immediately
at aq ualified specialist workshop. Mercedes-
Benz recommends that you use aMercedes-
Benz Service Centre for this purpose.
In particular, work relevant to safety or on
safety-related systems must be carried out at
aq ualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags During the first stage of
acollision, the airbag
control unit evaluates important physical
data relating to vehicle deceleration or accel-
eration, such as:
R duration
R direction
R magnitude
Based on the evaluation of this data, the air-
bag control unit pre-emptively triggers the
belt tensioners in the first stage.
i The belt tensioners can only be triggered
if the seat belt tongues are correctly
engaged in the seat belt buckles.
If there is an even higher rate of vehicle decel-
eration or acceleration in alongitudinal direc-
tion, the front airbags are also deployed.
Your vehicle has adaptive, two-stage front air-
bags. The airbag control unit evaluates vehi-
cle deceleration or acceleration in the event
of ac ollision. In the first deployment stage, Occupant safety

WARNING
If you wish to use seat covers, Mercedes-Benz
recommends that, for safety reasons, you
only use seat covers that have been approved
for Mercedes-Benz vehicles.
The seat covers must have aspecial tear seam
for sidebags/pelvisbags. Otherwise, the side-
bag/pelvisbag cannot deploy correctly and
would fail to provide the intended protection
in the event of an accident. Appropriate seat
covers can be obtained, for example, from a
Mercedes-Benz Service Centre.
When deployed, the sidebags offer additional
protection for the thorax of the vehicle occu-
pants on the side of the vehicle on which the
impact occurs. However, they do not protect
the:

WARNING
Only use headr estraint covers which have
been tested and approved by Mercedes-Benz
for yourv ehicle model.
The use of non-approved head restraint cov-
ers may preven tNECK-PRO head restraints
from triggering properly. Consequently, the
NECK-PRO head restraints cannot provide the
intended level of protection.
Consult aMercedes-Benz Service Centre
regarding availability.
If the NECK-PRO head restraint shave been
triggered in an accident, reset the NECK-PRO
head restraint sonthe driver’s and front-
passenger seat (Y page 46). Otherwise, the
additional protection will not be available in
the event of another rear-en dcollision. You
can recognise when NECK-PRO head
restraint shave been triggered by the fact that
they have moved forwards and can no longer
be adjusted. Resetting triggered NECK-PRO head
restraints
Following arear-en dcollision, Mercedes-
Benz recommends that you have NECK-PRO
head restraint schecked at aqualified spe-
cialist workshop, e.g. aMercedes-Benz
Service Centre.
i Resetting the NECK-PRO head restraints
requires alot of strength. If you have diffi-
culty resetting the NECK-PRO head
restraints, have this work carried out at a
qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre. Example: Coupé

X Repeat this procedure for the second
NECK-PRO head restraint. Seat belts
Important safety notes Seat belts are the most effective means of
restraining the movemen
tofvehicle occu-
pants in the event of an accident. This
reduces the risk of vehicle occupant scoming
into contact with parts of the vehicle interior. G
WARNING
As eat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, cannot perform its intended
protective function .Under certain circum-
stances, this could cause severe or even fatal
injuries in the event of an accident.
Make sure that all occupant s–inparticular,
pregnan twome n–w ear their seat belt cor-
rectly at all times.
R The seat belt must fit snugly on your body
and must no tbetwisted. Therefore, avoid 46

gbulky clothing, e.g .awinter coat.
The shoulde rbelt section must be routed
across the centre of your shoulder –onno
account across your neck or under your
arm –and pulled tight against your upper
body .The lap belt must always pass across
your lap as low down as possible, i.e. over
your hip joints–n ot across your abdomen.
If necessary, push down the belt strap
slightly and then retighten it in the roll-up
direction.
R Do not route the belt strap across sharp
edges or fragile objects, especially if these
are located on or in your clothing, e.g. spec-
tacles, pens, keys, etc. The seat belt strap
could be damaged and tear in an accident,
and you or other vehicle occupant scould
be injured.
R Only one person should use each seat belt
at any one time. Children must never travel
sittin gont he lap of other occupants. It
would not be possible to restrain the child
in the event of asudden change in direc-
tion, braking or an accident .This could
result in severe or even fatal injuries to the
child and other occupants.
R Persons less than 1.50 mtall cannot wear
the seat belts correctly. For this reason,
secure persons less than 1.50 mtall in spe-
cially designed ,suitable restraint systems.
R Children less than 1.50 mtall or unde r12
years of age canno twear the seat belts
properly. Therefore, they should alway sbe
secured in asuitable child restraint system
on asuitable vehicle seat. You can find
more information under "Children in the
vehicle" in the "Safety" section of the Own-
er's Manual. Follow the manufacturer's
installation instructions when fitting achild
restraint system.
R Do not secure any objects with aseat belt
if the seat belt is also being used by one of
the vehicle's occupants. G
WARNING
The seat belt does not offer the intended level
of protection unless the backrest is almost
vertical. Under certain circumstances, this
could cause severe or even fatal injuries in the
event of an accident.
Befor estarting ajourney, make sure that the
seat is properly adjusted and that the back-
rest is almost vertical. G
WARNING
Ad irtyord amaged seat belt or aseat belt that
has been subjected to aload in an accident
or which has been modified no longer offers
the intended level of protection. Under certain
circumstances, this could cause sever eor
even fatal injuries in the even tofanaccident.
For this reason, check regularly that the seat
belts are not damaged or dirty.

Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centr efor this pur-
pose.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat belts which have
been approved by Mercedes-Benz for your
vehicle.
Fastening seat belts The seat-belt extender for the driver and front

ment seat belts is only available for certain
countries.
Belt tensioners, belt force limiters The seat belts are fitted with belt tensioners.
The belt tensionerst ighten the seat belts in
an accident, pulling them close against the
body.
Belt tensionersdon ot correct incorrects eat
positions or incorrectly fastened seat belts.
Belt tensionersdon ot pull vehicle occupants
back towards the backrest.
If the seat belt is also fitted with abelt force
limiter and this is triggered, the force exerted
by the seat belt on the vehicle occupant is
reduced.
The belt force limiters for the front seats are
synchronised with the front airbags. These
take on apart of the deceleration force. Thus,
the force exerted on the occupant is distrib-
uted over agreater area.
The belt tensionersc an only be activated
when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 39).

R if, in the event of ahead-on or rear-en dcol-
lision, the vehicle decelerates or acceler-
ates rapidly in alongitudinal direction dur-
ing the initial stages of the impact
R if, in the event of aside impact, on the side
opposite the impact the vehicle deceler-
ates or accelerates rapidly in alateral direc-
tion
R Cabriolet: in certain situation sifthe vehicle
overturns and the system determines that
it can provide additional protection.
If the airbags are deployed, you will hear a
bang, and asmall 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. The 6SRS warning lamp
lights up. G
WARNING
If the seat belt tensioners have been trig-
gered, they provide no additional protection
in the event of another accident. Therefore,
have belt tensioners which have been trig-
gered replaced at aqualified specialist work-
shop.
Comply with safety regulations when dispos-
ing of belt tensioners .Any Mercedes-Benz
Service Centr ecan provide details of these
regulations.
! 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. 50
