regular intervals while the engine is running.
Therefore, malfunctions can be detected in
good time.
The u restraint system warning lamp in the
instrument cluster lights up when the ignition is
switched on. It goes out no later than a few sec-
onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
A malfunction has occurred if the u restraint
system warning lamp: R
does not light up after the ignition is switched
on R
does not go out after a few seconds with the
engine running R
lights up again while the engine is running
G WARNING
If restraint system is malfunctioning, restraint
system components may be triggered unin-
tentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emer-
gency Tensioning Device or air bag, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.
PASSENGER AIR BAG OFF indicator
lamp
PASSENGER AIR BAG OFF indicator lamp C is
part of the Occupant Classification System
(OCS). The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the front-
passenger front air bag.
If the PASSENGER AIR BAG OFF indicator
lamp: R
is lit : the front-passenger front air bag is
deactivated. It will then not be deployed in the
event of an accident. R
is not lit : 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.
Depending on the person in the front-passenger
seat, the front-passenger front air bag must
either be deactivated or enabled; see the fol-
lowing points. You must make sure of this both
before and during a journey. R
Children in a child restraint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the instal-
led child restraint system, and the age and
size of the child. Therefore, be sure to observe
the notes on the "Occupant Classification
System (OCS)" ( Y
page 49) and on "Chil-
dren in the vehicle" ( Y
page 58). There you
will also find instructions on rearward and
forward-facing child restraint systems on the
front-passenger seat. R
All other persons: depending on the classi-
fication of the person in the front-passenger
seat, the front-passenger front air bag is ena-
bled or deactivated ( Y
page 49). Be sure to
observe the notes on "Seat
belts“ ( Y
page 42) and "Air bags"
( Y
page 46). There you can also find infor-
mation on the correct seat position.
Seat belts
Introduction Seat belts are the most effective means of
restricting the movement of vehicle occupants
in the event of an accident or the vehicle rolling
over. This reduces the risk of vehicle occupants
coming into contact with parts of the vehicle
interior or being ejected from the vehicle. Fur-
thermore, the seat belt helps to keep the vehicle
occupant in the best position in relation to the
air bag.42
Occupant safety
Safety

PASSENGER AIRBAG OFF indicator lamp C
indicates whether the front-passenger front air
bag is disabled. X
Turn the SmartKey to position 1 or 2 in the
ignition lock, or in vehicles with KEYLESS-GO,
press the start/stop button once or twice.
The system carries out a self-diagnosis test.
The PASSENGER AIR BAG OFF indicator lamp
must light up for about six seconds.
The PASSENGER AIR BAG OFF indicator lamp
then shows the status of the front-passenger
front air bag. If the status of the front-passenger
front air bag changes whilst the vehicle is in
motion, an air bag display message may appear
in the instrument cluster ( Y
page 219). Always
observe the PASSENGER AIR BAG OFF indicator
lamp when the front-passenger seat is occu-
pied. Make sure that the status of the front-
passenger front air bag is correct before and
during a journey.
If the PASSENGER AIRBAG OFF indicator
lamp: R
lights up , the front-passenger front air bag is
disabled. It will then not be deployed in the
event of an accident. R
does not light up , the front-passenger front
air bag is enabled. If, in the case of an acci-
dent, all deployment criteria are met, the
front-passenger front air bag is deployed.
G WARNING
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. 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 ensure that: R
the classification of the person in the front-
passenger seat is correct and the front-
passenger front air bag 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 air bag is correct.
G WARNING
If you secure a child in a child restraint system
on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
off, the front-passenger front air bag can
deploy in the event of 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.
G WARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too
close to the dashboard, the child could, in the
event of an accident: R
come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example R
be struck by the air bag if the PASSENGER
AIR BAG OFF indicator lamp is off
This poses an increased risk of injury or even
fatal injury.
Move the front-passenger seat as far back as
possible. Always make sure that the shoulder
belt strap is correctly routed from the vehicle
belt sash guide 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 sash guide. If nec-
essary, adjust the vehicle belt sash guide and
the front-passenger seat accordingly. Always
observe the child restraint system manufac-
turer's installation instructions.50
Occupant safety
Safety

If OCS detects that: R
the front-passenger seat is not occupied, the
PASSENGER AIR BAG OFF indicator lamp
lights up continuously after the system's self-
diagnosis test. This indicates that the front-
passenger front air bag is deactivated. R
the front-passenger seat is occupied by a
child aged up to twelve months in a standard
child restraint system, the PASSENGER AIR
BAG OFF indicator lamp lights up continu-
ously after the system's self-diagnosis test.
This indicates that the front-passenger front
air bag is deactivated.
In the case of a twelve-month-old child in a
standard child restraint system, the
PASSENGER AIR BAG OFF indicator lamp may
go out after the system's self-diagnosis test.
This indicates that the front-passenger front
air bag is activated. Categorization is depend-
ent on the type of child restraint system and
the stature of the child, for example. In this
case, always install the child restraint system
on a suitable rear seat. R
the front-passenger seat is occupied by a per-
son of smaller stature (e.g. a teenager or a
small adult), the PASSENGER AIR BAG OFF
indicator lamp lights up continuously or goes
off after the system's self-diagnosis test
depending on the categorization. -
If the PASSENGER AIR BAG OFF indicator
lamp is off, position the front-passenger
seat as far back as possible. Alternatively, a
person of smaller stature can sit on a rear
seat. -
If the PASSENGER AIR BAG OFF indicator
lamp lights up, a person of smaller stature
should not sit on the front-passenger seat. R
the front-passenger seat is occupied by an
adult or a person of an appropriate size, the
PASSENGER AIR BAG OFF indicator lamp
goes out after the system's self-diagnosis
test. This indicates that the front-passenger
front air bag is activated.
If children are traveling in the vehicle, be sure to
observe the notes on "Children in the vehicle"
( Y
page 58).
If the OCS is malfunctioning, both the red u
restraint system warning lamp in the instrument
cluster and the PASSENGER AIR BAG OFF indi-
cator lamp light up simultaneously. In this case,
the front-passenger air bag is deactivated and
does not deploy during an accident. Ha ve
the
system checked by qualified technicians as soon as possible. Consult an authorized
Mercedes-Benz Center. Only have the front-
passenger seat repaired at an authorized
Mercedes-Benz Center.
If the front-passenger seat, the seat cover or the
seat cushion are 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's air bag deploys, this does not
mean that the front-passenger front air bag will
also deploy. The Occupant Classification Sys-
tem (OCS) categorizes the occupant on the
front-passenger seat. Depending on the result,
the front-passenger air bag is activated or deac-
tivated.
System self-test
G DANGER
If the PASSENGER AIR BAG OFF indicator
lamp does not light up during the system self-
test, then the system is malfunctioning. The
front-passenger front air bag might be trig-
gered unintentionally or might not be trig-
gered at all in the event of an accident with
high deceleration. 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 a child restraint system
on the front-passenger seat. Have the Occu-
pant Classification System (OCS) checked
and repaired immediately at a qualified spe-
cialist workshop.
G WARNING
If the PASSENGER AIR BAG OFF indicator
lamp remains lit after the system self-test, the
front-passenger front air bag is disabled. It will
not be deployed in the event of an accident. In
this case, the front-passenger front air bag
cannot perform its intended protective func-
tion, e.g. when a person is seated in the front-
passenger seat.
That person could, for example, come into
contact with the vehicle's interior, especially
if the person is sitting too close to the dash-Occupant safety 51
