remains lit. This indicates that the front-passenger front air bag is deactivated.
RThe front-passenger seat is occupied by achild of up to twelve months old, in a standardchild restraint system, the PASSENGER AIRBAG OFF indicator lamp lights up after thesystem self-test and remains lit. This indi-cates that the front-passenger front air bag isdeactivated.
But even in the case of a twelve-month-oldchild, in a standard child restraint system, thePASSENGER AIR BAG OFF indicator lamp cango out after the system self-test. This indi-cates that the front-passenger front air bag isactivated. The result of the classification isdependent on, among other factors, the childrestraint system and the child's stature. It isrecommended that you install the childrestraint system on a suitable rear seat.
RThe front-passenger seat is occupied by aperson of smaller stature (e.g. a teenager orsmall adult), the PASSENGER AIR BAG OFFindicator lamp lights up and remains lit afterthe system self-test depending on the resultof the classification or, alternatively, goes out.
-If the PASSENGER AIR BAG OFF indicatorlamp is off, move the front-passenger seatas far back as possible. Alternatively, a per-son of smaller stature can sit on a rear seat.
-If the PASSENGER AIR BAG OFF indicatorlamp is lit, a person of smaller statureshould not use the front-passenger seat.
RThe front-passenger seat is occupied by anadult or a person of adult stature, thePASSENGER AIR BAG OFF indicator lampgoes out after the system self-test. This indi-cates that the front-passenger front air bag isactivated.
If children are traveling in the vehicle, be sure toobserve the notes on "Children in the vehicle"(Ypage 59).
When the Occupant Classification System(OCS) is malfunctioning, the red urestraintsystem warning lamp on the instrument clusterand the PASSENGER AIR BAG OFF indicatorlamp light up simultaneously. The front-passenger front air bag is deactivated in thiscase and does not deploy during an accident.Have the Occupant Classification System (OCS)checked and repaired immediately at a qualifiedspecialist workshop. Mercedes-Benz recom-mends that you use an authorized Mercedes-Benz Center for this purpose.
If the front-passenger seat, the seat cover or theseat cushion are damaged, have the necessaryrepair work carried out at a qualified specialistworkshop. Mercedes-Benz recommends thatyou use an authorized Mercedes-Benz Centerfor this purpose.
For safety reasons, Mercedes-Benz recom-mends that you only use seat accessories thathave been approved by Mercedes-Benz.
If the driver's air bag deploys, this does notmean that the front-passenger front air bag willalso deploy. The Occupant Classification Sys-tem (OCS) categorizes the occupant on thefront-passenger seat. Depending on that result,the front-passenger front air bag is either ena-bled or deactivated.
Self-check
GDANGER
If the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps do
not both light up during the self-test, the sys-
tem is malfunctioning. The front-passenger
front air bag might be triggered unintention-
ally or might not be triggered 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.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp remains lit after the self-test, the front-
passenger front air bag is deactivated. 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-

GWARNING
The front-passenger front air bag does not deploy during an accident.
There is an increased risk of injury.
XPull over and stop the vehicle safely as soon as possible, payingattention to road and traffic conditions.
XSecure the vehicle against rolling away (Ypage 152).
XSwitch the ignition off.
XHave the occupant on the front-passenger seat get out of the vehi-cle.

Ra self-diagnosis is carried out. The PASSENGER AIR BAG OFF andPASSENGER AIR BAG ON indicator lamps must light up simulta-neously for approximately six seconds.
Rthe PASSENGER AIR BAG OFF indicator lamp must then light upand remain lit after the self-diagnosis. If the indicator lamp is on,OCS (Occupant Classification System) has disabled the front-passenger front air bag (Ypage 51)

XWait for a period of at least 60 seconds until the necessary systemchecks have been completed.
XMake sure that the display messages do not appear in the multi-function display.
If these conditions are fulfilled, the front-passenger seat can be occu-pied again. Whether the PASSENGER AIR BAG OFF indicator lampremains lit or goes out depends on how OCS classifies the occupant.
If the conditions are not fulfilled, the system is not operating correctly.
