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. H
Environmental note
Have defective high-voltage batteries dis-
posed of in an environmentally responsible
manner. Consult a qualified specialist work-
shop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose. 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.

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. 24
Introduction

If a child younger than 12 years old and under
1.50 m in height is travelling in the vehicle:
R always secure the child in a child restraint
system suitable for this Mercedes-Benz
vehicle. The child restraint system must be appropriate to the age, weight and size of
the child
R be sure to observe the instructions and
safety notes on the automatic front-
passenger front airbag deactivation system (Y page 54)
R always observe the instructions and safety
notes on "Children in the vehicle" in this
Owner's Manual (Y page 63) in addition
to the child restraint system manufactur-
er's installation instructions G
WARNING
Seat belts cannot protect as intended, if:
R they are damaged, have been modified, are
extremely dirty, bleached or dyed
R the seat belt buckle is damaged or
extremely dirty
R modifications have been made to the belt
tensioners, belt anchorages or inertia reels
Seat belts may sustain non-visible damage in an accident, e.g. due to glass splinters. Modi-
fied or damaged seat belts can tear or fail, for example in the event of an accident. Modified
seat belt tensioners may be deployed unin-
tentionally or fail to be deployed when
required. There is an increased risk of injury,
possibly even fatal.
Never modify safety belts, seat belt tension-
ers, seat belt anchorages and inertia reels.
Ensure that seat belts are not damaged or
worn and are clean. After an accident, have
the seat belts checked immediately at a quali- fied specialist workshop.
Mercedes-Benz recommends that you only
use seat belts which have been approved
specifically for your vehicle by Mercedes-
Benz. Any such modifications could invalidate the vehicle's general operating permit. Correct seat belt use Observe the safety notes on the seat belt
(Y
page 47).
All vehicle occupants must be wearing the
seat belt correctly before beginning the jour- ney. Also make sure that all vehicle occu-
pants are always wearing the seat belt cor-
rectly while the vehicle is in motion.
When fastening the seat belt, always make
sure that:
R the seat belt tongue is only inserted to the
belt buckle belonging to that seat.
R the seat belt is tight across your body.
Avoid wearing bulky clothing, e.g. a winter
coat.
R the seat belt is not twisted.
Only then can forces which occur be dis-
tributed across the surface of the seat belt.
R the shoulder section of the belt is always
routed across the centre of your shoulder.
The shoulder section of the seat belt should
not touch your neck nor be routed under
your arm. If possible, adjust the seat belt to
the appropriate height.
R the lap belt passes across your lap as
tightly and as low down as possible.
The lap must always be routed across your
hip joints and never across your abdomen.
This applies particularly to pregnant
women. If necessary, press the lap belt
down into your hip joints and pull tight with the shoulder section of the belt.
R the seat belt is not routed across sharp,
pointed or fragile objects.
If you have such items located on or in your
clothing, e.g. pens, keys or spectacles,
store these in a suitable place.
R only one person is using a seat belt.
Infants and children must never travel sit-
ting on the lap of a vehicle occupant. In the
event of an accident, they could be crushed 48

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 328). 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 there is no child restraint system fitted to
the front-passenger seat, the front-passenger
must sit:
R 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 does not 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.
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 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.
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 59). Occupant safety

PRE-SAFE
®
PLUS intervenes in certain situa-
tions if the radar sensor system detects an
imminent head-on or rear-end collision.
PRE-SAFE ®
PLUS takes the following meas-
ures depending on the hazardous situation
detected:
R If the radar sensor system detects that a
head-on collision is imminent, the seat
belts are pre-tensioned.
R If the radar sensor system detects that a
rear-end collision is imminent:
- the rear hazard warning lamps are acti-
vated and flash at a higher frequency.
- the brake pressure is increased if the
driver applies the brakes when the vehi-
cle is stationary.
- the seat belts are pre-tensioned.
The PRE-SAFE ®
PLUS braking application is
cancelled:
R if the accelerator pedal is depressed when
a gear is engaged
R if the risk of a collision passes or is no lon-
ger detected
R if DISTRONIC PLUS indicates an intention
to pull away
If the hazardous situation passes without
resulting in an accident, the original settings
are restored. Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on
the type and severity of the impact:
R the hazard warning lamps are activated
R the emergency lighting is activated
R the vehicle doors are unlocked
R the front side windows are lowered
R vehicles with a memory function: the elec-
trically adjustable steering wheel is raised
R the engine is switched off R

Important safety notes
Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front-passenger seat. For this reason, Mercedes-Benz strongly advises
that you install a child restraint system on a
rear seat. Children are generally better pro-
tected there.
If a child younger than 12 years old and under 1.50 m in height is travelling in the vehicle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehi-
cles. The child restraint system must be
appropriate to the age, weight and size of
the child
R be sure to observe the instructions and
safety notes in this section in addition to
the child restraint system manufacturer's
installation instructions
R always pay attention to the instructions
and safety notes on the automatic front-
passenger front airbag deactivation system
(Y page 54) G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position Por shift manual transmission into
neutral
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury. Children in the vehicle

securing systems checked in a qualified spe-
cialist workshop before fitting a child restraint
system again.
Securing systems for the child restraint sys-
tem are: R the seat belt system
R the ISOFIX securing rings
R the Top Tether anchorages
If it is absolutely necessary to carry a child on
the front-passenger seat, be sure to observe
the information on "Child restraint systems
on the front-passenger seat" (Y page 66).
Observe the warning labels in the vehicle inte-
rior and on the child restraint system.
i It is advisable to use Mercedes-Benz care
products to clean child restraint systems
recommended by Mercedes-Benz. You can obtain information about this at any
Mercedes-Benz Service Centre. ISOFIX child seat securing system
G
WARNING
ISOFIX child restraint systems do not offer
sufficient protective effect for children whose weight is greater than 22 kg who are securedusing the safety belt integrated in the child
restraint system. The child could, for example, not be restrained correctly in the event of an
accident. This poses an increased risk of
injury or even fatal injury.
If the child weighs more than 22 kg, only use
ISOFIX child restraint systems with which the child is also secured with the vehicle seat belt. Also secure the child restraint system with the
Top Tether belt, if available.
When fitting a child restraint system, be sure to observe the manufacturer's installation
instructions and the instructions for correct
use of the child restraint system
(Y page 68). Before every trip, make sure that the ISOFIX
child restraint system is engaged correctly in
both ISOFIX securing rings.
! When fitting the child restraint system,
make sure that the seat belt for the centre
seat does not get trapped. Otherwise, the
seat belt could be damaged. :
ISOFIX securing rings
Vehicles with rear seat armrest: adjust the
rear seat armrest so that ISOFIX securing
rings :for the ISOFIX child restraint system
are accessible.
X Install the ISOFIX child restraint system on
both ISOFIX securing rings :.
ISOFIX is a standardised securing system for specially designed child restraint systems on
the rear seats. ISOFIX securing rings :for
two ISOFIX child restraint systems are fitted
on the left and right of the rear seats.
Secure child restraint systems without an
ISOFIX child seat securing system using the
seat belts in the vehicle. When fitting a child
restraint system, be sure to observe the man-
ufacturer's installation and operating instruc-
tions and the instructions for correct use of
the child restraint system (Y page 68). Top Tether
Introduction Top Tether provides an additional connection
between the child restraint system secured
with ISOFIX and the vehicle. It helps reduce
the risk of injury even further. If the child Children in the vehicle

Always observe the information on suitable
positioning of the child restraint system
(Y page 68) in addition to the child restraint
system manufacturer's installation and oper- ating instructions.
Forward-facing child restraint system If it is absolutely necessary to fit a forward-
facing child restraint system to the front-
passenger seat, always move the front-
passenger seat as far back as possible. Fully
retract the seat cushion length. The entire
base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the child
restraint system must, as far as possible, be
resting on the backrest of the front-
passenger seat. The child restraint system
must not touch the roof or be put under strain
by the head restraint. Adjust the angle of the seat backrest and the head restraint position
accordingly. Always make sure that the shoul- der belt strap is correctly routed from the
vehicle belt outlet to the shoulder belt guide
on the child restraint system. The shoulder
belt strap must be routed forwards and down-
wards from the vehicle belt outlet. If neces-
sary, adjust the vehicle belt outlet and the
front-passenger seat accordingly.
Always observe the information on suitable
positioning of the child restraint system
(Y page 68) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions. Suitable positioning of the child
restraint system
Introduction Only child restraint systems which are
approved in accordance with the ECE stand-
ard ECE R44 are permitted for use in the vehi- cle.
For certain child restraint systems in weight
categories II or III, this can mean that the area
of use is restricted. The maximum size setting of the child restraint system is not possible
due to possible contact with the roof.
"Universal" category child restraint systems
can be recognised by their orange approval
label and the text "Universal".
Example: approval label on the child restraint sys-
tem
"Universal" category child restraint systems
can be used on the seats indicated with U, UF
or IUF according to the tables "Suitability of
the seats for attaching belt-secured child
restraint systems" or "Suitability of the seats
for attaching an ISOFIX child restraint sys-
tem".
Semi-universal child restraint systems are
indicated by the text "Semi-universal" on the
approval label. These can be used if the vehi- cle and the seat are listed in the child restraintsystem manufacturer's vehicle model list. For
more information, contact the child restraint
system manufacturer or visit their website.

X Move the front-passenger seat as far back
as possible and fully retract the seat cush-
ion length.
X Move the backrest to an almost vertical
position.
The entire base of the child restraint sys-
tem must always rest on the seat cushion of the front-passenger seat. The backrest of
the forward-facing child restraint system
must, as far as possible, be resting on the
backrest of the front-passenger seat. The
child restraint system must not touch the
roof or be put under strain by the head
restraint. Adjust the angle of the seat back- rest and the head restraint position accord-
ingly. Also observe the child restraint sys-
tem manufacturer's installation instruc-
tions.
X Move the seat cushion angle to the highest,
most vertical position.
Suitability of the seats for attaching
belt-secured child restraint systems If you use a baby car seat of category 0 or 0+
or a rearward-facing child restraint system of category I on a rear seat, you must adjust the
driver's or front-passenger seat so that the
seat does not touch the child restraint sys-
tem.
If you use a forward-facing child restraint sys-
tem from category I, you must, where possi- ble, dismantle the head restraint of the
respective seat (Y page 122). The backrest of
the child restraint system must, as far as pos- sible, lie flat against the backrest of the seat.
Always observe the notes in the "Child
restraint system" section (Y page 64) and the
child restraint system manufacturer's instal-
lation instructions.
When you remove the child restraint system,
you must immediately replace the head
