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

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

Airbags
Introduction The installation location of an airbag is iden-
tified by the AIRBAG symbol.
An airbag supplements a correctly worn seat
belt. It is not a replacement for the seat belt. The airbag offers additional protection in
applicable accident situations.
Not all airbags are deployed in an accident.
The different airbag systems work independ-
ently of each other (Y page 62).
However, no system available today can com-
pletely eliminate injuries and fatalities.
It is also not possible to completely rule out a risk of injury caused by an airbag due to the
speed at which the airbag must be deployed.
Important safety notes G
WARNING
If you deviate from the correct seat position,
the airbag cannot perform its intended pro-
tective function and can even cause addi-
tional injuries when deployed. There is an
increased risk of serious or even fatal injuries.
In order to avoid such risks, always ensure
that all vehicle occupants:
R fasten their seatbelts correctly, including
pregnant women
R are seated correctly and maintain the fur-
thest possible distance from the airbags
R observe the following notes
Always ensure that there are no objects loca-
ted between the airbag and the vehicle occu-
pant.
R Adjust the seats properly before beginning
your journey. Always make sure that the
seat is in an almost upright position. The
centre of the head restraint must support
the head at about eye level.
R Move the driver's and front-passenger
seats as far back as possible. The driver's
seat position must allow the vehicle to be
driven safely. R
Only hold the steering wheel on the out-
side. This allows the airbag to be fully
deployed.
R Always lean against the backrest while driv-
ing. Do not lean forwards or lean against
the door or side window. You may other-
wise be in the deployment area of the air-
bags.
R Always keep your feet in the footwell in
front of the seat. Do not put your feet on the
dashboard, for example. Your feet may oth-
erwise be in the deployment area of the
airbag.
R Always secure persons less than 1.50 mtall
in suitable restraint systems. Up to this
height, the seat belt cannot be worn cor-
rectly.
If a child is travelling in your vehicle, also
observe the following notes:
R Always secure children under twelve years
of age and less than 1.50 mtall in suitable
child restraint systems.
R Child restraint systems should be fitted to
the rear seats.
R Only secure a child to the front-passenger
seat when the front-passenger front airbag
is disabled, and only then in a rearward-
facing child restraint system. If the
PASSENGER AIR BAG OFF indicator lamp is
permanently lit, the front-passenger front
airbag is disabled .
R Always observe the instructions and safety
notes on the automatic front-passenger
front airbag deactivation system
(Y page 56) and on "Children in the vehi-
cle" (Y page 65) in addition to the child
restraint system manufacturer's installa-
tion instructions. Occupant safety
53Safety Z

Operation of automatic front-passenger
front airbag deactivation :
PASSENGER AIR BAG ON indicator lamp
; PASSENGER AIR BAG OFF indicator lamp
The indicator lamps inform you whether the
front-passenger front airbag is disabled or
enabled.
X Press the Start/Stop button once or twice,
or turn the key to position 1or 2in the
ignition lock.
The system carries out a self-diagnosis.
The PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps
must light up simultaneously for approx-
imately six seconds.
The indicator lamps display the status of the
front-passenger front airbag: R PASSENGER AIR BAG ON lights up: the
front-passenger front airbag is enabled. If,
in the event of an accident, all deployment
criteria are met, the front-passenger front
airbag is deployed.
R PASSENGER AIR BAG OFF lights up: the
front-passenger front airbag is disabled. It
will then not be deployed in the event of an
accident.
If the status of the front-passenger front air-
bag changes while the vehicle is in motion, an
airbag display message appears in the instru-
ment cluster (Y page 349). When the front-
passenger seat is occupied, always pay atten-
tion to the PASSENGER AIR BAG ON and
PASSENGER AIR BAG OFF indicator lamps. Be aware of the status of the front-passenger front airbag both before and during the jour-
ney.
If a person sits in the passenger seat, they
must be:
R seated with the seat belt fastened correctly
R in an almost upright position with their
back against the seat backrest
R with their feet resting on the floor, if possi-
ble
If the front passenger does not observe these
conditions, the automatic front-passenger
front airbag deactivation system may be influ-
enced, e.g. because the front passenger:
R transfers their weight by supporting them-
selves on a vehicle armrest
R sits in such a way that their weight is raised
from the seat cushion
The front-passenger front airbag may be dis-
abled by mistake as a result of these or similar actions. In this case, the PASSENGER AIR
BAG OFF indicator lamp lights up perma-
nently. The front-passenger front airbag doesnot then deploy during an accident. G
WARNING
If the PASSENGER AIRBAG OFF indicator lamp is lit, the front-passenger front airbag is disa-
bled. It will not be deployed in the event of an
accident and cannot perform its intended pro-
tective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always make sure that:
R the classification of the person in the front-
passenger seat is correct and that the front-
passenger front airbag is enabled or disa-
bled in accordance with the person in the
front-passenger seat.
R the front-passenger seat has been moved
back as far back as possible.
R the person is seated correctly. Occupant safety

Make sure, both before and during the jour-
ney, that the status of the front-passenger
front airbag is correct. G
WARNING
If you secure a child on the co-driver's seat in a rearward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The child could be struck by the airbag. There is an
increased risk of injury, possibly even fatal.
In this case, always ensure that the co-driver's
airbag is disabled. The PASSENGER AIRBAG
OFF indicator lamp must light up.
If the PASSENGER AIR BAG OFF indicator
lamp remains off and/or the PASSENGER AIR BAG ON indicator lamp lights up, do not install
a rearward-facing child restraint system on
the front-passenger seat. Further information can be found under "Problems with the auto-matic front-passenger front airbag deactiva-
tion system" (Y page 61). G
WARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too close to the dashboard, in the event of an
accident, the child could:
R come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
R be struck by the airbag if the PASSENGER
AIR BAG ON indicator lamp is lit
This poses an increased risk of injury or even fatal injury.
Always move the front-passenger seat as far
back as possible and fully retract the seat
cushion length. Always make sure that the
shoulder belt strap is correctly routed from
the vehicle belt outlet to the shoulder belt
guide on the child restraint system. The shoul-
der belt strap must be routed forwards and
downwards from the vehicle belt outlet. If
necessary, adjust the vehicle belt outlet and the 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.
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
system, the PASSENGER AIR BAG OFF indi-
cator 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, the PASSENGER AIR
BAG ON indicator lamp can light up after
the system self-test and remain lit. This
indicates that the front-passenger front air- bag is enabled. The result of the classifica-tion is dependent on, among other factors,
the child restraint system and the child's
build. It is recommended 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 ON or
PASSENGER AIR BAG OFF indicator lamp
lights up and remains lit after the system
self-test depending on the result of the
classification. The result of the classifica-
tion is dependent on, among other factors, the child restraint system and the child's
build.
Move the front-passenger seat as far back
as possible. Always observe the informa-
tion in "Child restraint systems on the front- passenger seat" (Y page 69) and in "Suit-
able positioning of the child restraint sys-
tem" (Y page 71). Alternatively, you can 58

WARNING
If you secure a child on the co-driver's seat in a rearward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The childcould be struck by the airbag. There is an
increased risk of injury, possibly even fatal.
In this case, always ensure that the co-driver's
airbag is disabled. The PASSENGER AIRBAG
OFF indicator lamp must light up.
NEVER use a rearward facing child restraint
on a seat protected by an ACTIVE AIRBAG in
front of it; DEATH or SERIOUS INJURY to the
CHILD can occur.
If the PASSENGER AIR BAG ON indicator lamp
is lit, the front-passenger front airbag is ena-
bled (Y page 48). Vehicles without the automatic front-
passenger front airbag deactivation
system If the front-passenger seat of your vehicle is
not equipped with the automatic front-
passenger front airbag deactivation system,
this is indicated by a special sticker. The
sticker is affixed to the side of the dashboard
on the front-passenger side. The sticker is
visible when you open the front-passenger
door.
Always fit the rearward-facing restraint sys-
tem to a suitable rear seat in this case
(Y page 71).
Observe the following information under
"Rearward-facing child restraint system" and
"Forward-facing child restraint system" as
well as information on the suitable position-
ing of the child restraint system
(Y page 71).
Rearward-facing child restraint system If it is absolutely necessary to fit a rearward-
facing child restraint system to the front-
passenger seat, always make sure that the
front-passenger front airbag is disabled. Only
if the PASSENGER AIR BAG OFF indicator
lamp is lit continuously (Y page 48)is the
front-passenger front airbag disabled.
Always observe the information on suitable
positioning of the child restraint system
(Y page 71) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions. 70
