Protection of the environment
General notes
H Environmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that 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 tire wear are affected
by these 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
always make sure that the tire pressures
are correct. R
do not carry any unnecessary weight. 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 service work 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
Important safety notes The use of seat belt s and child restrain t systems
is require d by law in:R
all 50 state sR
th e U.S. territoriesR
th e Distric t of ColumbiaR
all Canadian province s
Even wher e this is no t require d by law, all vehicl e
occupant s should correctl y faste n their seat
belt s before starting th e journey.
G WARNIN G
If th e seat belt is incorrectl y fastened, it can -
no t protect as intended. Furthermore , an
incorrectl y fastene d seat belt can caus e addi-
tional injury, for example, in an accident, dur-
ing braking or when abruptl y changing direc-
tion . This poses an increased ris k of injury or
eve n fatal injury.
Mak e sur e that all vehicl e occupant s are
seated properly wit h a correctl y fastene d seat
belt .
G WARNIN G
The seat belt does no t offer th e intended level
of protection if you have no t moved th e back-
res t to an almost vertical position . When brak -
ing or in th e event of an accident, you could
slide underneat h th e seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased ris k of injury or eve n fatal
injury.
Adjus t th e seat properly before beginning
your journey. Always ensur e that th e backrest
is in an almost vertical position and that th e
shoulder section of your seat belt is routed
across th e center of your shoulder .
G WARNIN G
Objects next to th e fron t seat that bloc k th e
belt buckle or th e moving belt anchorage on
th e fron t seat impair th e function of th e Emer-
gency Tensioning Devices. The Emergency
Tensioning Devices may no t function as inten -
ded and th e seat belt may no longer provide
th e intended protection . This poses an
increased ris k of injury or eve n fatal injury. Before starting th e journey, mak e sur e that
there are no objects aroun d th e belt buckle or
between th e fron t seat and door .
G WARNIN G
Person s under 5 ft (1.50 m) in height canno t
faste n th e seat belt correctl y without an addi-
tional suitable restrain t system. If th e seat
belt is incorrectl y fastened, it canno t protect
as intended. Furthermore , an incorrectl y fas -
tene d seat belt can caus e additional injury, for
example, in an accident, during braking or an
abrup t chang e of direction . This poses an
increased ris k of injury or eve n fatal injury.
Fo r this reason , always secure person s under
5 ft (1.50 m) in height in suitable restrain t
systems .
If a child younger than twelve years old and
under 5 ft (1.5 0 m) in height is traveling in the
vehicle: R
always secure the child in a child restraint
system suitable for this Mercedes-Benz vehi-
cle. The child restraint system must be appro-
priate to the age, weight and size of the child R
always observe the instructions and safety
notes on the belt bags for the outer seat belts
in the rear ( Y
page 48) R
always observe the instructions and safety
notes on "Children in the vehicle"
( Y
page 61) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions R
be sure to observe the instructions and safety
notes on the "Occupant classification system
(OCS)" ( Y
page 53)
G WARNING
The seat belts may not perform their intended
protective function if: R
they are damaged, modified, extremely
dirty, bleach or dyed R
the seat belt buckle is damaged or
extremely dirty R
the Emergency Tensioning Devices, belt
anchorages or inertia reels have been modi-
fiedOccupant safety 47
Safety Z
The side impact air bag on the front-passenger
side (front) deploys under the following condi-
tions: R
the OCS system detects that the front-
passenger seat is occupied or R
the belt tongue is engaged in the belt buckle
of the front-passenger seat
If the belt tongue is engaged in the belt buckle,
the side impact air bag on the front-passenger
side deploys if an appropriate accident situation
occurs. In this case, deployment is independent
of whether the front-passenger seat is occupied
or not.
Window curtain air bags
Window curtain air bags C are integrated into
the side of the roof frame and deployed in the
area from the A-pillar to the C-pillar.
When deployed, the window curtain air bag
enhances the level of protection for the head.
However, it does not protect the chest or arms.
In the event of a side impact, the window curtain
air bag is deployed on the side on which the
impact occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a window curtain air bag may be
deployed in other accident situations
( Y
page 57).
Cushion air bags
i Observe the "Important safety notes" sec-
tion ( Y
page 50).
The rear reclining seat is equipped with a cush-
ion air bag. If the seat backrest is reclined, the
cushion air bag can provide additional occupant
protection in the event of frontal collision situa-
tions. When triggered, the cushion air bag
deploys under the seat cushion. This helps pre- vent the occupant from slipping off the seat
cushion.
G WARNING
If a child restraint system is installed and the
seat backrest is reclined too far backwards,
the cushion air bag may deploy by mistake in
the event of an accident. There is an increased
risk of injury.
When using a child restraint system, always
ensure that the seat is correctly adjusted and
that the backrest is almost vertical.
If you install a child restraint system on the rear
reclining seat, always observe: R
the instructions and safety notes in "Children
in the vehicle" ( Y
page 61) R
the child restraint system manufacturer's
installation instructions
Occupant Classification System
(OCS)
Introduction The Occupant Classification System (OCS) cat-
egorizes the person in the front-passenger seat.
Depending on that result, the front-passenger
front air bag is either enabled or deactivated.
The system does not deactivate: R
the side impact air bag R
the window curtain air bag R
the Emergency Tensioning Devices
Prerequisites To be classified correctly, 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 possible
If the front passenger does not observe these
conditions, OCS may produce a false classifica-
tion, 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 cushionOccupant safety 53
