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 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
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
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. G
WARNING
Airbag functionality can only be assured if the
following
parts are not covered and no badges
or stickers are attached to them:
R padded steering wheel boss
R kneebag cover below the steering column
R front-passenger airbag cover
R outer side of front seat bolsters
R side trim next to the rear seat backrest
R roof frame cover between the front A-pillar
and the C-pillar in the rear compartment G
WARNING
When an airbag deploys, a small amount of
powder is released. The powder may cause
short-term breathing difficulties to persons
suffering from asthma or other pulmonary
conditions. In order to prevent potential breathing diffi-
culties, 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 powder does not constitute a
health hazard and does not indicate that there
is a fire in the vehicle. G
WARNING
The airbag parts are hot after the airbag has
been deployed. Do not touch them as you
could burn yourself.
Have the airbags replaced at a qualified spe-
cialist workshop. Otherwise, occupants are
not protected by the airbags in the event of
another accident.
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. The 6 SRS warning lamp
lights up.
The airbag installation locations are identified
by the AIRBAG symbol.
Front airbags !
Do not place heavy objects on the front-
passenger seat. The system may then
detect

that the seat is occupied and if there
is an accident, the restraint systems on the
front-passenger side could be deployed.
Have restraint systems that have been trig-
gered replaced. Occupant safety

deploy correctly and would fail to provide the
intended protection in the event of an acci-
dent. Appropriate seat covers can be
obtained,
for example, from a Mercedes-Benz
Service Centre. Front sidebags : and rear sidebags
;
deploy next to the outer seat cushions.
When

deployed, the sidebags offer additional
protection of the thorax for occupants on the
front seats as well as also of the pelvis for the
vehicle occupants on the side of the vehicle
on which the impact occurs. However, they
do not protect the:
R head
R neck
R arms
The sidebags are deployed:
R on the side on which an impact occurs
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 independently of the use of the seat belt
R independently of the front airbags
R independently of the belt tensioners
If the vehicle overturns, the sidebags are gen-
erally not deployed. Sidebags are deployed if
the system detects high vehicle deceleration
or acceleration in a lateral direction and
determines that sidebag deployment can
offer additional protection to that provided by
the seat belt. Windowbags
Windowbags
: enhance the level of protec-
tion for the head (but not chest or arms), of
the

vehicle occupants on the side of the vehi-
cle on which the impact occurs.
Windowbags : are integrated into the side
of the roof frame and deployed in the area
from the A-pillar to the C-pillar.
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

WARNING
When adjusting the seat, make sure that
nobody can become trapped.
! 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. Occupant safety

PRE-SAFE
®
takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations.
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:
X Move the backrest or seat back slightly, but
only when the vehicle is stationary.
The belt pretensioning is reduced and the
locking mechanism is released.

a convenience function integrated into PRE-
SAFE

(Y page 47). Seat belts
Important safety notes G
WARNING
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
— on no 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 — not across your abdo-
men. If necessary, push the seat belt
slightly downwards and adjust it by pulling
it in the direction the seat belt retracts.
R Do not route the seat belt strap over sharp
or fragile objects. Please make sure that
such objects are not on or in your clothing,
e.g. spectacles, pens or keys etc. The seat
belt strap could become damaged and tear
during an accident and you or other vehicle
occupants could be injured.
R Only one person should use each seat belt
at any one time. Children must never travel
sitting on the lap of another occupant. The
child will not be secured in the event of an
accident, heavy braking or sudden change
of direction. This may result in the child or
other occupants being seriously or fatally
injured.
R Persons under 1.50 m tall cannot wear the
seat belts correctly. For this reason secure
persons less than 1.50 m tall in specially
designed, suitable restraint systems.
R Children under 1.50 m tall and younger
than twelve years of age cannot wear the
seat belts correctly. For this reason secure
them in special suitable child restraint sys-
tems installed on a suitable seat. Additional
information can be found in the Operating
Instructions in the chapter "Safety", "Chil-
dren in the Vehicle". Observe the installa-46

Important safety notes G
WARNING
Activate the child-proof locks for the rear
doors and the override switch for the rear
windows when children are travelling in the
vehicle. Otherwise, the children could open
doors or side windows while the vehicle is in
motion and injure themselves or others. G
WARNING
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system. They could injure them-
selves

on parts of the vehicle. They could also
be seriously or even fatally injured by pro-
longed exposure to extreme heat or cold.
Do not expose the child restraint system to
direct sunlight. Parts of the child restraint sys-
tem could heat up and the child could burn
herself/himself on them. If a child opens a door, the child or other per-
sons could be injured as a result. They could
get

out and injure themselves or be injured by
a passing vehicle.
Observe the general notes on the HOLD func-
tion, which can be found under the same key-
word.
