Protecting 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 am anner
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 condition sofy our vehicleR
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
ar egularly 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
startin gt he engine.R
do not warm up the engine when the vehicle
is stationary. R
drive carefully and maintain as afe 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

If ac hild younger than twelve years old and
under 5ft( 1.5 0m)inh eight is travelin gint he
vehicle: R
always secur et he child in ac hild restraint
system suitable for this Mercedes-Ben zv ehi-
cle. The child restraint system must be appro-
priat etot he age, weight and size of the child.R
always observe the instructions and safety
notes on "Children in the vehicle"
( Y
page 53) in addition to the child restraint
system manufacturer' si nstallation and oper-
atin gi nstructionsR
always observe the instructions and safety
notes on the "Occupant classification system
(OCS)" ( Y
page 45)
G WARNING
The seat belts may not perform their intended
protective function if: R
the ya re damaged, modified, extremely
dirty, bleache dord yedR
the seat belt buckle is damaged or

anchorage sori nertia reels have been modi-
fied.

Safety Z

The system does not deactivate: R
the side impact air bag R
the headbag R
the Emergency Tensionin gD evices
Requirements 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 restin gont he floor, if possible
If the front passenger does not observe these
conditions, OCS may produce af alse classifica-
tion, e.g. because the front passenger: R
transfers their weight by supporting them-
selves on av ehicle armrestR
sits in such aw ay that their weight is raised
from the seat cushion
If you install ac hild restraint system on the
front-passenger seat, be sure to observe the
correc tp ositionin goft he child restraint system.
Never place object su nder or behind the child
restraint system, e.g. ac ushion. The entir eb ase
of the child restraint system must alway sr est on
the seat cushion of the front-passenger seat.
The backrest of the forward-facing child
restraint system must lie as flat as possible
against the backrest of the front-passenger
seat.
The child restraint system must not touch the
roof or be subjected to al oad by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint sys-
tem manufacturer's installation and operating
instructions. Occupant Classification System opera-

PASSENGER AIR BAG ON indicator lamp D
PASSENGER AIR BAG OFF indicator lamp
The indicator lamps inform you whether the
front-passenger front air bag is deactivated or
enabled. X
Press the Start/Stop button once or twice, or
turn the SmartKey to position G or H in the
ignition lock.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul-
taneously for approximately six seconds.
The indicator lamps display the status of the
front-passenger front air bag. R
PASSENGER AIR BAG ON lights up for 60 sec-
onds, subsequently both indicator lamps are
off (PASSENGER AIR BAG ON and OFF): the
front-passenger front air bag is able to deploy
in the event of an accident. R
PASSENGER AIR BAG OFF lights up: the front-
passenger front air bag is deactivated. It will
then not be deployed in the event of an acci-
dent.
If the PASSENGER AIR BAG ON indicator lamp is
off, only the PASSENGER AIR BAG OFF indicator
lamp shows the status of the front-passenger
front air bag. The PASSENGER AIR BAG OFF
indicator lamp may be lit continuously or be off.
If the status of the front-passenger front air bag
changes while the vehicle is in motion ,ana ir bag
display message appears in the instrument clus-
ter ( Y
page 187). When the front-passenger
seat is occupied, alway sp ay attention to the
PASSENGER AIR BAG OFF indicator lamp. Be
aware of the status of the front-passenger front
air bag both before and during the journey.46

Safety

Problem
Possible causes/consequences and P Solutions
The PASSENGER AIR
BAG OFF indicator lamp
lights up and remains lit,
even though the front-
passenger seat is occu-
pied by an adult or ap er-
son of as tature corre-
sponding to that of an
adult. The classification of the person on the front-passenger seat is incor-
rect. X
Make sure the condition sf or ac orrect classification of the person
on the front-passenger seat are met ( Y
page 46).X
If the PASSENGER AIR BAG OFF indicator lamp remains lit, the front-
passenger seat may not be used. X
Have OCS checked as soon as possible at an authorized Mercedes-
Benz Center.
The PASSENGER AIR
BAG OFF indicator lamp
does not light up and/or
does not stay on.
The front-passenger seat
is: R
unoccupied R
occupied by the
weight of ac hild up to
twelve months old in a
child restraint system OCS is malfunctioning. X
Make sure there is nothin gb etween the seat cushion and the child
seat. X
Make sure that the entire base of the child restraint system rests on
the seat cushion of the front-passenger seat. The backrest of the
forward-facing child restraint system must lie as flat as possible
against the backrest of the front-passenger seat. If necessary,
adjust the position of the front-passenger seat. X
When installing the child restraint system, make sure that the seat
belt is tight. Do not pull the seat belt tight using the front-passenger
seat adjustment .T his could result in the seat belt and the child
restraint system being pulled too tightly. X
Check for correct installation of the child restraint system.
Make sure that the head restraint does not apply al oad to the child
restraint system. If necessary, adjust the head restraint accord-
ingly. X
Make sure that no object sa re applying additional weight onto the
seat. X
If the PASSENGER AIR BAG OFF indicator lamp remains off and/or
the PASSENGER AIR BAG ON indicator lamp lights up, do not install
ac hild restraint system on the front-passenger seat. X
Have OCS checked as soon as possible at an authorized Mercedes-
Benz Center.
