The shoulder section of the seat belt must
always be routed across the center of the
shoulder. Adjust the belt outlet if necessary.
X To raise: slide the belt outlet upwards.
The belt outlet will engage in various posi-
tions.
X To lower: hold belt outlet release 0043and
slide the belt outlet downwards.
X Let go of belt outlet release 0043in the
desired position and make sure that the
belt outlet engages.
All seat belts except the driver's seat belt are equipped with a special seat belt retractor tosecurely fasten child restraint systems in the
vehicle. Further information can be found
under "Special seat belt retractor"
(Y page 59).
Releasing seat belts !
Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door,
the door trim panel and the seat belt. Dam- aged seat belts can no longer fulfill their
protective function and must be replaced.
Visit a qualified specialist workshop. X

tongue 0044firmly and guide it back towards

Belt warning for the driver and front
passenger The
0076 seat belt warning lamp in the instru-
ment cluster is a reminder that all occupants must fasten their seat belts. It may light up
continuously or flash. In addition, there may
be a warning tone.
Regardless of whether the driver's seat belt
has already been fastened, the 0076seat belt
warning lamp lights up for six seconds each
time the engine is started. If, after
six seconds, the driver or front-passenger
seat belt has not been fastened and the doors are closed, the 0076seat belt warning lamp
lights up again. As soon as the driver's and
front-passenger seat belts are fastened or a
front door is opened again, the 0076seat belt
warning lamp goes out.
If the driver's seat belt is not fastened after
the engine is started, an additional warning
tone will sound. This warning tone stops after six seconds or when the driver's seat belt is
fastened.
If the vehicle's speed exceeds 15 mph
(25 km/h) once and the driver's and front-
passenger seat belts are not fastened, a
warning tone sounds. The warning tone
sounds with increasing intensity for
60 seconds or until the driver or front
passenger have fastened their seat belts.
If the driver or front passenger unfasten their seat belts during the journey, the seat belt
warning is activated again.

0076seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat
belts" (Y page 252). Occupant safety

Occupant Classification System
(OCS)
Introduction The Occupant Classification System (OCS)
categorizes the person in the front-passenger
seat. Depending on that result, the front-
passenger front air bag and front-passenger
knee bag are 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 possi-
ble
If the front passenger does not observe these conditions, OCS may produce a false classi-
fication, 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
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
be sure to observe the correct positioning of
the child restraint system. Never place
objects under or behind the child restraint
system, e.g. cushions. The entire base of the
child restraint system must always rest on the
seat cushion of the front-passenger seat. The
backrest of the forwards-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.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint
system manufacturer's installation instruc-
tions.

The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps
must light up simultaneously for approx-
imately six seconds.
The indicator lamps display the status of the
front-passenger front air bag.
R PASSENGER AIR BAG ON 0043lights up: the
front-passenger front air bag is enabled. If,
in the event of an accident, all deployment
criteria are met, the front-passenger front
air bag is deployed.

front-passenger front air bag is deactiva-
ted. It will then not be deployed in the event
of an accident. Occupant safety

General notes If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi-
cle will not be cooled. The air inside the vehi-cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore, only
deactivate the "Cooling with air-dehumidifi-
cation" function briefly.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
Condensation may drip from the underside of the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc- tion. Operating the climate control systems

Further information on holding the vehicle
stationary on uphill gradients (Y page 151).ECO start/stop function
Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is stop- ped under certain conditions.
The engine starts automatically when the
driver wants to pull away again. The ECO
start/stop function thereby helps you to
reduce the fuel consumption and emissions
of your vehicle.
Important safety notes G
WARNING
If the engine is switched off automatically and you exit the vehicle, the engine is restarted
automatically. The vehicle may begin moving. There is a risk of accident and injury.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.
General notes 0043
ECO start/stop display
If the engine has been switched off automat-
ically by the ECO start/stop function, the 00A7
symbol is shown in the multifunction
display.
The stop/start function is automatically acti-
vated each time you start the engine with the SmartKey.
AMG vehicles: the ECO start/stop function
is only available in drive program C.
Automatic engine switch-off If the vehicle is braked to a standstill in
Dor N,
the ECO start/stop function switches off the engine automatically.
The ECO start/stop function is operational
when:
R the indicator lamp in the ECO button is lit
green.
R the off-road program is deactivated.
R the outside temperature is within the range
that is suitable for the system.
R the engine is at normal operating temper-
ature.
R the set temperature for the vehicle interior
has been reached.
R the battery is sufficiently charged.
R the system detects that the windshield is
not fogged up when the air-conditioning
system is switched on.
R the hood is closed.
R the driver's door is closed and the driver's
seat belt is fastened.
i All of the vehicle's systems remain active
when the engine is stopped automatically.
i The HOLD function can also be activated
if the engine has been switched off auto-
matically. It is then not necessary to con-
tinue applying the brakes during the auto-
matic stop phase. When you depress the
accelerator pedal, the engine starts auto-
matically and the braking effect of the
HOLD function is deactivated.
i The engine can be switched off automat-
ically a maximum of four times (first stop
and three subsequent stops) in succession. Driving
