MERCEDES-BENZ C-Class COUPE 2017 CL205 Workshop Manual

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:are integrated into
the side of the roof frame and deployed in the
area from the A-pillartot he 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 aside 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 providedbyt he
seat belt, awindow curtain air bag may be
deployed in other accident situations
(
Ypage 53).
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 enable dordeactivated.
The system does not deactivate:
Rthe side impact air bag
Rthe window curtain air bag
Rthe Emergency Tensioning Devices
Prerequisites
To be classified correctly, the front passenger
must sit:
Rwith the seat belt fastened correctly
Rin an almos tupright positionw ith their back
against the seat backrest
Rwith their feet resting on the floor, if possible
If the front passenger does not observe these
conditions, OCS may produce afalse classifica-
tion, e.g. because the front passenger:
Rtransfers their weight by supporting them-
selves on avehicle armrest
Rsits in such away that their weight is raised
from the seat cushion
If it is absolutely necessary to install achild
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. Full yretract the seat cushio nlength.
The entire base of the child restraint system
must always rest on the seat cushio nofthe
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 aload by the head
restraint. Adjust the angle of the seat backrest
and the head restraint positiona ccordingly.
Only then can OCS be guaranteed to function
correctly. Alway sobserve the child restraint sys-
tem manufacturer's installation and operating
instructions.

The indicator lamps inform you whether the
front-passenger front air bag is deactivated or
enabled.
XPress the Start/Stop button once or twice, or
turn the SmartKey to position1or 2in 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.
RPASSENGER AIR BAG ON lights 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.
RPASSENGER 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 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 (
Ypage 229). When the front-passenger
seat is occupied, alwaysp ay attention to the
PASSENGER AIR BAG ON and PASSENGER AIR
BAG OFF indicator lamps. Be aware of the status
of the front-passenger front air bag both before
and during the journey.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag is
disabled. It will not be deployed in the event of
an accident and cannot perform its intended
protective function. Aperson in the front-
passenger seat could then ,for example, come
into contact with the vehicle's interior, espe-
cially if the person is sittin gtoo close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
alwayse nsure that:
Rthe classification of the person in the front-
passenger seat is correcta nd the front-
passenger front air bag is enabled or disa-
bled in accordanc ewith the person in the
front-passenger seat
Rthe front-passenger seat has been moved
back as far back as possible.
Rthe person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front air bag is correct.
GWARNING
If you secure achild in arearward-facing child
restraint system on the front-passenger seat
and the PASSENGER AIR BAG ON indicator
lamp is lit up, the front-passenger front air bag may deploy in an accident .The child could be
struck by the air bag. This poses an increased
risk of injury or even fatal injury.
Make sure that the front-passenger front air
bag has been disabled. The PASSENGER AIR
BAG OFF indicator lamp must be lit.
If the PASSENGER AIR BAG OFF indicator lamp
remains off and/or the PASSENGER AIR BAG
ON indicator lamp lights up, do not install arear-
ward-facing child restraint system on the front-
passenger seat. You can find more information
on OCS under "Problems with the Occupant
Classification System" (
Ypage 53).
GWARNING
If you secure achild in aforward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too close to the dashboard, in the event of an
accident ,the child could:
Rcome into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
Rbe struck by the air bag if the PASSENGER
AIR BAG ON is lit up
This poses an increased risk of injury or even fatal injury.
Always move the front-passenger seat as far
back as possible and fully retrac tthe seat
cushion length. Always make sure that the
shoulder belt strap is correctly routed from
the vehicle belt sash guide to the shoulder

Safety

belt guide on the child restraint system. The
shoulder belt strap must be routed forwards
and downwards from the vehicle belt sash
guide. If necessary, adjust the vehicle belt
sash guide and the front-passenger seat
accordingly. Always observe the child
restraint system manufacturer's installation
instructions.
If OCS determines that:
Rthe front-passenger seat is unoccupied, the
PASSENGER AIR BAGO FF indicator lamp
lights up after the system self-test and
remains lit. This indicates that the front-
passenger fronta ir bag is deactivated.
Rthe front-passenger seat is occupied by a
child of up to twelve months old, in astandard
child restraint system, the PASSENGER AIR
BAGO FF indicator lamp lights up after the
system self-test and remains lit. This indi-
cates that the front-passenger fronta ir bag is
deactivated.
But even in the case of atwelve-month-old
child, in astandard child restraint system, the
PASSENGER AIR BAGONc an light up perma-
nently after the system self-test. This indi-
cates that the front-passenger fronta ir bag is
activated. The result of the classification is
dependen ton, among other factors, the child
restraint system and the child's stature. It is
recommended that you install the child
restraint system on asuitable rear seat.
Rthe front-passenger seat is occupied by aper-
son of smaller stature (e.g. ateenager or
small adult), either the PASSENGER AIR BAG
ON or PASSENGER AIR BAGO FF indicator
lamp lights up and remains lit after the system
self-test dependin gonthe result of the clas-
sification.
-If the PASSENGER AIR BAGONi ndicator
lamp lights up, move the front-passenger
seat as far back as possible. Alternatively, a
person of smaller stature can sit on arear
seat.
-If the PASSENGER AIR BAGO FF indicator
lamp is lit, aperson of smaller stature
should not use the front-passenger seat.
Rthe front-passenger seat is occupied by an
adult or aperson of adult stature, the
PASSENGER AIR BAGONi ndicator lamp
lights up after the system self-test and remains lit. This indicates that the front-
passenger fronta
ir bag is activated.
If children are traveling in the vehicle, be sure to
observe the notes on "Children in the vehicle"
(
Ypage 57).
When OCS is malfunctioning, the red 6
restraint system warning lamp in the instrument
cluster and the PASSENGER AIR BAGO FF indi-
cator lamp light up simultaneously. The front-
passenger fronta ir bag is deactivated in this
case and does not deploy during an accident.
Have the system checked by qualified techni-
cians as soon as possible. Consult an authorized
Mercedes-Benz Center .The front-passenger
seat should only be repaired at an authorized
Mercedes-Benz Center.
If the front-passenger seat, the seat cover or the seat cushion is damaged, have the necessary
repair work carried out at an authorized
Mercedes-Benz Center.
For safety reasons ,Mercedes-Benz recom-
mends that you only use seat accessories that
have been approved by Mercedes-Benz.
If the driver'sa ir bag deploys, this does not
mean that the front-passenger fronta ir bag will
also deploy. The Occupant Classification Sys-
tem (OCS) categorizes the occupant in the front-
passenger seat. Depending on that result, the
front-passenger fronta ir bag is either enabled or
deactivated.
System self-test
GDANGER
If both the PASSENGER AIR BAGO FF and
PASSENGER AIR BAGONi ndicator lamps do
not light up during the system self-test, the
system is malfunctioning. The front-
passenger fronta ir bag might be triggered
unintentionally or might not be triggered at all
in the event of an accidentw ith high deceler-
ation. This poses an increased risk of injury or
even fatal injury.
In this case the front-passenger seat may not
be used. Do not install achild restraint system
on the front-passenger seat. Have the Occu-
pant Classification System (OCS) checked
and repaired immediately at aqualified spe-
cialist workshop.
