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 a manner
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 conditions of your 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 a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R always have maintenance work carried out
at a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
Personal driving style
R do not depress the accelerator pedal when
starting the engine.
R do not warm up the engine with the vehicle
stationary. R
drive carefully and maintain a safe distance
from the vehicle in front.
R avoid frequent, sudden acceleration.
R change gear in good time and use each gear
only up to ⅔ofits maximum engine speed.
R switch off the engine in stationary traffic. Returning use
dvehicles
Mercedes-Ben zwill take back your
Mercedes-Ben zto dispose of it in an environ-
mentally responsible manner ,inaccordance
with the European Union (EU) End of Life
Vehicles Directive.
The End of Life Vehicles Directive applies to
vehicles of up to 3.5 tgross vehicle weight, in
accordance with national regulations. For
several years, Mercedes-Benz has been
meeting all the legal requirements for a
design which allows for recycling and reuse.
There is a network of return points and dis-
assembly plants which can recycle yourv ehi-
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-Benzh omepage
or your national hotline number. Vehicle equipment
This manual describes all the standard and
optional equipment of your vehicle available
at the time of publication of the Owner's Man-
ual. Country-specific differences are possi-
ble. Bear in mind that your vehicle may not
feature all functions described here. This also
refers to safety-related systems and func-
tions. The equipment in your vehicle may
therefore differ from that shown in the
descriptions and illustrations. All the systems
found in your vehicle are listed in the original Introduction

R
Rearward-facing child restrain tsystems
must not be fitted to the front-passenger
seat unless the front-passenger airbag has
been disabled. On the front-passenger
seat, the front-passenger airbag is disabled
if a child restrain tsystem with automatic
child seat recognition is fitted to the front-
passenger seat .The 4 PASSENGER
AIRBAG OFF indicator lamp must be con-
tinuously 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 automatic
child seat recognition, 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 possi-
ble.
R Make sure there are no heavy or sharp-
edged objects in the pockets of items of
clothing.
R Do not lean forwards, e.g. over the cover of
the driver's/front-passenger airbag, partic-
ularly when the vehicle is in motion.
R Do not put your feet on the dashboard.
R Only hold the steering wheel by the rim.
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
Risk of injury
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
Risk of injury
As mall amount of powder is released when
an airbag is deployed. The powder could
cause short-term breathing difficulties in peo-
ple with asthma or other respiratory prob-
lems.
In order to prevent 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 interior. The pow-
der does not constitute ahealth hazard and
does not indicate that there is a fire in the
vehicle. G
Risk of injury
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. Occupant safety
37Safety Z

the vehicle occupants on the side of the vehi-
cle on which the impact occurs.
The windowbags are integrated into the side
of the roo
fframe and deploy in the area
extending from the front door (A-pillar) to the
rear door (C-pillar). Windowbags
: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 deceleratio noraccelera-
tion, e.g. in a side impact
R regardless of whethe rthe front-passenger
seat is occupied
R independently of seat belt use
R if the vehicle overturns and the system
determines that windowbag deployment
can offer additional protection to that pro-
vided by the seat belt
R independently of the front airbags PRE-SAFE
®
(preventative occupant
protection)
PRE-SAFE ®
takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations.
PRE-SAFE ®
intervenes:
R in emergency braking situations, e.g. if BAS
is activated or intervenes powerfully in vehicles with DISTRONIC PLUS, BAS PLUS
or PRE-SAFE ®
Brake
R if the radar sensor system detects an immi-
nent danger of collision in certain situa-
tions (on vehicles with DISTRONIC PLUS)
R in critical situations involving driving
dynamics, e.g. if the vehicle oversteers or
understeers significantly due to physical
limits being exceeded or if the vehicle
swerves to avoid an obstacle at a speed of
over 140 km/h.
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: under
accident conditions, it adjusts the front-
passenger seat if it is in an unfavourable
position.
R vehicles with a multicontour seat or an
active multicontour seat: the air pressure
in the side bolsters on the seat cushion and
the side bolsters on the backrest is
increased.
R if the vehicle skids, the sliding sunroof/
panorama sliding sunroof and the side win-
dows 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. The air pressure in the
side bolsters on the multicontour seat/active
multicontour seat is reduced again. All set-
tings 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 releases. G
Risk of injury
When adjusting the seat, make sure that
nobody can become trapped. 40
