Depending on that result, the front-passenger

GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenge rfront air bag is
disabled. It wil lnot be deploye dinthe event of
an accident and cannot perform its intended
protective function. Apersonint he front-
passenger seat coul dthen, for example, come
into contact with the vehicle's interior, espe-
cially if the personiss itting too close to the
dashboard. This posesani ncreased risk of
injury or even fatal injury.
When the front-passenge rseat is occupied,
alway sensure that:
Rthe classification of the personint he front-
passenger seat is correct and the front-
passenger front air bag is enabled or disa-
bledina ccordance with the personint he
front-passenge rseat
Rthe front-passenge rseat has been moved
back as far back as possible.
Rthe personiss eated 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-passenge rseat
and the PASSENGER AIR BAG OFF indicator
lamp is off, the front-passenge rfront air bag
can deploy in the event of an accident. The
child coul dbestruck by the air bag .This poses
an increased risk of injury or even fatal injury.
Make sure that the front-passenge rfront air
bag has been deactivated. The PASSENGER
AIR BAG OFF indicator lamp must be lit.
NEVER use arearward-facing child restraint
on aseat protected by an ACTIVE FRONT AIR-
BAG in front of it; DEATH or SERIOUS INJURY
to the child can occur.
If the PASSENGER AIR BAG OFF indicator lamp
stays off, do not instal larearward-facing child
restraint system on the front-passenge rseat.
You can find more information on OCS under
"Problems with the Occupant Classification Sys-
tem" (
Ypage4 9).
GWARNING
If you secure achild in aforward-facing child
restraint system on the front-passenge rseat
and you position the front-passenge rseat 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 OFF indicator lamp is off
This poses an increased risk of injury or even fatal injury.
Move the front-passenge rseat as far back as
possible.A lways make sure that the shoulder
belts trap is correctly routed from the vehicle
beltg uide to the shoulderb eltguide on the
child restraint system. The shoulderb eltstrap
must be routed forwards and downwards
from the vehicleb eltguide. Always observe
the child restraint system manufacturer's
installation instructions.
If OCS determines that:
RThe front-passenge rseat is unoccupied,t he
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and
remains lit. This indicates that the front-
passenger front air bag is deactivated.
RThe front-passenge rseat is occupied by a
child of up to twelve months old, in astandard
child restraint system, the PASSENGER AIR
BAG OFF indicator lamp lights up after the
system self-test and remains lit. This indi-
cates that the front-passenge rfront air bag is
deactivated.
But even in the case of atwelve-month-old
child ,inas tandard child restraint system, the
PASSENGER AIR BAG OFF indicator lamp can
go out after the system self-test. This indi-
cates that the front-passenge rfront air bag is
activated. The result of the classification is
dependent on, among other factors, the child
restraint system and the child's stature. Make
sure that the conditions for acorrect classi-
ficatio nare met. If the PASSENGER AIR BAG
OFF indicator lamp remains off, do not install
ac hild restraint system on the front-
pa

ssenger seat.

RThe front-passenger seat is occupied by a
person of smaller stature (e.g.ateenager or
small adult), the PASSENGER AIR BAG OFF
indicator lamp lights up and remains lit after
the system self-test depending on the result
of the classification or, alternatively, goes out.
-If the PASSENGER AIR BAG OFF indicator
lamp is off, move the front-passenger seat
as far back as possible.
-If the PASSENGER AIR BAG OFF 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 BAG OFF indicator lamp
goes out after the system self-test. This indi-
cates 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"
(
Ypage 53).
When the Occupant Classification System
(OCS) is malfunctioning, the red 6restraint
system warning lamp on the instrument cluster
and the PASSENGER AIR BAG OFF indicator
lamp light up simultaneously. The front-
passenger front air bag is deactivated in this
case and does not deploy during an accident.
Have the Occupant Classification System (OCS)
checked and repaired immediately at aqualified
specialist 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 the seat cushion are damaged, have the necessary
repair work carried out at aqualified specialist
workshop. Mercedes-Benz recommends that
you use an authorized Mercedes-Benz Center
for this purpose.
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. Dependin gonthat result,
the front-passenger front air bag is either ena-
bled or deactivated.
System self-test
GDANGER
If both the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps do
not light up during the system self-test, the
system is malfunctioning. The front-
passenger front air bag might be triggered
unintentionally or might not be triggered at all
in the event of an accident with 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.
GWARNING
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 aperson 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 sittin gtoo close to the dash-
board. 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 person is seated properly with acor-
rectly fastened seatbelt
Rthe front-passenger seat has been moved
as far back as possible

Metho dofoperation
During the firs tstag eofac ollision, the restraint
system control uni tevaluates important physi-
cal data relating to vehicle deceleration or accel-
eration, such as:
Rduration
Rdirection
Rintensity
Base dont he evaluation of this data, the
restraint system control uni ttriggers the Emer-
gency Tensioning Devices during afrontalo r
rearc ollision. An Emergency Tensioning Device can only be
triggered, if:
Rthe ignition is switched on
Rthe components of the restraint system are
operational

by evaluating the rate of vehicle deceleration or
acceleration which occurs at variousp oints in
the vehicle .Thisp rocess is pre-emptive in
nature. Deployment shoul dtake place in good

The rate of vehicle deceleration or acceleration
and the direction of the force are essentially
