grated into the seats. Consequently, the air
bags cannot protect vehicle occupants as
they are designed to do. In addition, the func-tion of the Occupant Classification System
(OCS) could be restricted. This poses an
increased risk of injury or even fatal injury.
You should only use seat covers that have
been approved for the respective seat by
Mercedes-Benz.
Side impact air bags :deploy next to the
outer bolster of the seat backrest.
When deployed, the side impact air bag offers
additional thorax protection. However, it does
not protect the:
Rhead
Rneck
Rarms
In the event of a side impact, the side impact
air bag is deployed on the side on which the
impact occurs.
The side impact air bag on the front-
passenger side deploys under the following
conditions:
Rthe OCS system detects that the front-
passenger seat is occupied or
Rthe belt tongue is engaged in the belt
buckle of the front-passenger seat
If the belt tongue is engaged in the belt
buckle, the side impact air bag on the front-
passenger side deploys if an appropriate acci-
dent situation occurs. In this case, deploy-
ment is independent of whether the front-
passenger seat is occupied or not.
Head bags
Head bags :deploy in the area of the side
windows at the front.
When deployed, the headbag enhances the
level of protection for the head. However, it
does not protect the:
Rchest
Rarms
In the event of a side impact, the headbag is
deployed on the side on which the impact
occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a headbag may be deployed in other
accident situations (
Ypage 54).
The headbag on the front-passenger side
does not deploy under the following condi-
tions:
ROCS has detected that the front-passenger
seat is unoccupied.
Rthe front-passenger seat belt is not fas-
tened.
If the belt tongue is engaged in the belt
buckle, the headbag on the front-passenger
side deploys if an appropriate accident situa-
tion occurs. In this case, deployment is inde-
pendent of whether the front-passenger seat
is occupied or not.

Safety

If the status of the front-passenger front air
bag changes while the vehicle is in motion, an
air bag display message appears in the instru-
ment cluster (
Ypage 223). When the front-
passenger seat is occupied, always pay atten-
tion 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 jour-
ney.
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. 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:
Rthe 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
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 a child in a rearward-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
a rearward-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 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, 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.
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 loop to the shoulder belt guide on the
child restraint system. The shoulder belt strap
must be routed forwards and downwards
from the belt loop. Always observe the child
restraint system manufacturer's installation
instructions.
If OCS determines that:
Rthe front-passenger seat is unoccupied, the
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-passenger seat is occupied by a
child of up to twelve months old, in a stand-
ard child restraint system, the PASSENGER
AIR BAG OFF indicator lamp lights up after
the system self-test and remains lit. This
50Occupant safety
Safety

indicates that the front-passenger front airbag is deactivated.
But even in the case of a twelve-month-old
child, in a standard child restraint system,
the PASSENGER AIR BAG ON can light up
permanently after the system self-test. This
indicates that the front-passenger front airbag is activated. The result of the classifi-
cation is dependent on, among other fac-
tors, the child restraint system and the
child's stature. Make sure that the condi-
tions for a correct classification are met. If
the PASSENGER AIR BAG ON indicator
lamp is still lit, do not install a child restraint system on the front-passenger seat.
Rthe front-passenger seat is occupied by a
person of smaller stature (e.g. a teenager
or small adult), either the PASSENGER AIR
BAG ON or PASSENGER AIR BAG OFF indi-
cator lamp lights up and remains lit after
the system self-test depending on the
result of the classification.
-If the PASSENGER AIR BAG ON indicatorlamp lights up, move the front-passenger
seat as far back as possible.
-If the PASSENGER AIR BAG OFF indicator
lamp is lit, a person of smaller stature
should not use the front-passenger seat.
Rthe front-passenger seat is occupied by an
adult or a person of a stature correspond-
ing to that of an adult, the PASSENGER AIR BAG ON indicator lamp lights up after the
system self-test and remains lit. This indi-
cates that the front-passenger front air bag
is activated.
If children are traveling in the vehicle, be sure
to observe t
he notes on "Children in the vehi- cle" (
Ypage 57).
When OCS is malfunctioning, the red 6
restraint system warning lamp in the instru-
ment cluster and the PASSENGER AIR BAG
OFF indicator lamp light up simultaneously.
The front-passenger front air bag is deactiva-
ted in this case and does not deploy during an accident. Have the system checked by quali-
fied technicians 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 nec-
essary repair work carried out at an author-
ized 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
System (OCS) categorizes the occupant in the
front-passenger seat. Depending on that
result, the front-passenger front air bag is
either enabled 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 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.
GDANGER
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-

GWARNING
Objects between the seat surface and the
child restraint system could affect OCS oper- ation. This could result in the front-passenger
air bag not functioning as intended during an
accident. This poses an increased risk of
injury or even fatal injury.
Do not place any objects between the seat
surface and the child restraint system. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the forward-
facing child restraint system must, as far as
possible, be resting on the backrest of the
front-passenger seat. Always comply with the
child restraint system manufacturer's instal-

ently of each other in certain frontal collision
situations:
RFront air bags as well as driver's and front-
passenger knee bags
The front-passenger front air bag is activated or deactivated depending on the person on
the front-passenger seat. The front-
passenger front air bag can only deploy in an
accident if the PASSENGER AIR BAG ON indi- cator lamp is lit. Observe the information on
the PASSENGER AIR BAG indicator lamps
(
Ypage 41).
Your vehicle has two-stage front air bags.
During the first deployment stage, the front
air bag is filled with propellant gas to reduce
the risk of injuries. The front air bag is fully
deployed with the maximum amount of pro-
pellant gas if a second deployment threshold
is reached within a few milliseconds.
The activation threshold of the Emergency
Tensioning Devices and the air bag are deter-
mined by evaluating the rate of vehicle decel-
eration or acceleration which occurs at vari-
ous points in the vehicle. This process is pre- emptive in nature. Deployment should take
place in good time at the start of the collision.
The rate of vehicle deceleration or accelera-
tion and the direction of the force are essen-
tially determined by:
Rthe distribution of forces during the colli-
sion
Rthe collision angle
Rthe deformation characteristics of the vehi-
cle
Rthe characteristics of the object with which
the vehicle has collided
Factors which can only be seen and measured
after a collision has occurred do not play a
decisive role in the deployment of an air bag.
Nor do they provide an indication of air bag
deployment.
The vehicle can be deformed considerably,
without an air bag being deployed. This is the case if only parts which are relatively easily
deformed are affected and the rate of decel-
eration is not high. Conversely, air bags may be deployed even though the vehicle suffers
only minor deformation. This is the case if, for
example, very rigid vehicle parts such as lon-
gitudinal body members are hit
, and sufficient
deceleration occurs as a result.
If the restraint system control unit detects a
side impact or if the vehicle rolls over, the
applicable components of the restraint sys-
tem are activated independently of each
other depending on the apparent type of acci-
dent.
RSide impact air bag on the side of impact,
independently of the Emergency Tension-
ing Device and the use of the seat belt on
the driver's seat
The side impact air bag on the front-
passenger side deploys under the following
conditions:
-the OCS system detects that the front-
passenger seat is occupied or
-the belt tongue is engaged in the belt
buckle of the front-passenger seat
RHead bag on the side of impact, independ-
ently of the use of the seat belt and inde-

iNot all air bags are deployed in an acci-
dent. The different air bag systems work
independently of each other.
