WARNING
Modifications to the restraint systems could
result in them not functioning properly any
more. The restraint systems could then no
longer protect vehicle occupants as they are designed to do and could fail in the event of an
accident or activate unexpectedly, for exam-
ple. There is an increased risk of injury.
Never modify parts of the restraint systems.
Do not attempt to modify the wiring as well as
electronic components or their software.
If it is necessary to modify an air bag system to accommodate a person with disabilities, con-tact an authorized Mercedes-Benz center.
USA only: for further information contact our
Customer Assistance Center at
1-800-FOR-MERCedes (1800-367-6372).
In this section, you will learn the most impor- tant facts about the restraint system compo-
nents of the vehicle.
The restraint system consists of:
R Seat belts
R Child restraint systems
R LATCH-type (ISOFIX) child seat securing
system
Additional protection is provided by:
R SRS (Supplemental Restraint System)
R Air bag system components with:
- PASSENGER AIR BAG OFF indicator lamp
- Front-passenger seat with Occupant
Classification System (OCS)
Although the systems are independent, their
protective functions work in conjunction with each other. Not all air bags are always
deployed in an accident.
i For information on infants and children
traveling with you in the vehicle restraint
systems for infants and children, see "Chil-
dren in the vehicle" (Y page 56). SRS (Supplemental Restraint System)
Introduction Supplemental Restraint System (SRS) with:
R The 0075 SRS warning lamp
R Air bags
R Air bag control unit (with crash sensors) 40
Occupant safetySafety

R
do not lean your head or chest close to the
steering wheel or dashboard.
R only hold the steering wheel on the outside.
Placing hands and arms inside the rim can
increase the risk and potential severity of
hand/arm injury if the driver front air bag
inflates.
R adjust the front-passenger seat as far back
as possible from the dashboard when the
seat is occupied.
R occupants, especially children, should
never place their bodies or lean their heads
in the area of the door where the side
impact air bag inflates. This could result in
serious or fatal injuries should the side
impact air bag be deployed. Always sit as
upright as possible, wear the seat belt prop-
erly and use an appropriately sized infant
restraint, toddler restraint or booster seat
recommended for the size and weight of the
child.
Failure to follow these instructions can result in severe injuries to you or other occupants.
If you sell your vehicle, it is important that you
make the buyer aware of this safety informa-
tion. Be sure to give the buyer this Operator's
Manual.
If the air bags are deployed, you will hear a
bang, and a small amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard and does not indicate that there is a fire in the vehicle. The dust might cause
some temporary breathing difficulty for peo-
ple with asthma or other breathing trouble. To avoid this, you may wish to get out of the
vehicle as soon as it is safe to do so. You can
also open the window to allow fresh air to
enter the vehicle interior. The 0075SRS warn-
ing lamp lights up.
The air bag installation locations are identi-
fied by the AIR BAG symbol.
The air bags are deployed if the air bag control
unit detects the need for deployment. Only in the event of such a situation will the air bags
provide their supplemental protection.
If the driver and front passenger do not wear their seat belts, it is not possible for the air
bags to provide their supplemental protec-
tion.
In the event of other types of impacts and
impacts below air bag deployment thresh-
olds, the air bags will not deploy. The driver
and passenger will then be protected to the
extent possible by a properly fastened seat
belt. A properly fastened seat belt is also nee- ded to provide the best possible protection in
a rollover.
Air bags provide additional protection; they
are not, however, a substitute for seat belts.
All vehicle occupants must fasten their seat
belts regardless of whether your vehicle is
equipped with air bags or not.
It is important for your safety and that of your
passenger to have deployed air bags replaced and to have any malfunctioning air bags
repaired. This will help to make sure the air
bags continue to perform their protective
function for the vehicle occupants in the
event of a crash.
i After an air bag has been deployed, have
the vehicle towed to the nearest qualified
specialist workshop, even if your vehicle is
ready to drive.

Occupant safetySafety

The side impact air bag on the front-
passenger side will deploy if the front-
passenger seat belt is fastened, regardless of whether the front-passenger seat is occupied
or not.
The side impact air bag on the front-
passenger side does not deploy under the fol-
lowing conditions:
R OCS has detected that the front-passenger
seat is unoccupied.
R the front-passenger seat belt is not fas-
tened.
Window curtain air bags Window curtain air bags
0043enhance the level
of protection for the head, but not chest or
arms, of the vehicle occupants on the side of the vehicle on which the impact occurs.
Window curtain air bags 0043are integrated
into the side of the roof frame and deployed in the area from the A-pillar to the C-pillar.
Window curtain air bags are deployed:
R at the start of an accident with a high rate of
lateral vehicle deceleration or acceleration,
e.g. in a side impact
R on the side on which an impact occurs
R on the driver's side and passenger side, in
the event of a vehicle rollover and if the
system determines that air bag deployment
can offer the vehicle occupants additional
protection to that provided by the seat belt
R independently of the use of the seat belt R
regardless of whether the front-passenger
seat is occupied
R independently of the front air bags
Window curtain air bags 0043will not deploy in
the event of impacts which do not exceed the
system's preset deployment thresholds for
vehicle acceleration/deceleration. You will
then be protected by the fastened seat belt. Occupant Classification System

WARNING
If the 00730074 indicator lamp illuminates
when an adult or someone larger than a small individual is in the front-passenger seat, havethe front passenger reposition himself or her-
self in the seat until the 00730074indicator
lamp goes out.
In the event of a collision, the air bag control
unit will not allow front-passenger front air
bag deployment when the OCS has classified
the front-passenger seat occupant as weigh-
ing as much as or less than a typical 12-
month-old child in a standard child restraint or if the front-passenger seat is classified as
being empty.
When the OCS senses that the front-
passenger seat occupant is classified as
being up to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 00730074indicator lamp will
illuminate when the engine is started and
remain illuminated, indicating that the front-
passenger front air bag is deactivated.
When the OCS senses that the front-
passenger seat is classified as being empty,
the 00730074 indicator lamp will illuminate
when the engine is started and remain illumi-
nated, indicating that the front-passenger

being heavier than the weight of a typical 12-
month-old child seated in a standard child
restraint or as being a small individual (such
as a young teenager or a small adult), the
00730074 indicator lamp will illuminate for
approximately 6 seconds when the engine is
started and then, depending on occupant
weight sensor readings from the front-
passenger seat, remain illuminated or go out. With the 00730074 indicator lamp illumina-
ted, the front-passenger front air bag is deac-
tivated. With the 00730074indicator lamp
out, the front-passenger front air bag is acti-
vated.
When the OCS senses that the front-
passenger seat occupant is classified as an
adult or someone larger than a small individ-
ual, the 00730074 indicator lamp will illumi-
nate for approximately 6 seconds when the
engine is started and then go out, indicating
that the front-passenger front air bag is acti-
vated.
If the 00730074 indicator lamp is illuminated,
the front-passenger front air bag is deactiva-
ted and will not be deployed.
If the 00730074 indicator lamp is not illumi-
nated, the front-passenger front air bag is
activated and will be deployed:
R in the event of certain frontal impacts
R if impact exceeds a preset deployment
threshold
R independently of the side impact air bags
If the front-passenger front air bag is
deployed, the rate of inflation will be influ-
enced by:
R the rate of relevant vehicle deceleration as
assessed by the air bag control unit
R the front passenger's weight category as
identified by OCS G
WARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus, we strongly recommend that children be placed in the rear seats whenever possible.
Regardless of seating position, children 12
years old and under must be seated and prop- erly secured in an appropriate infant restraint,
toddler restraint, or booster seat recommen-
ded for the size and weight of the child.
The infant or child restraint must be properly
secured with the vehicle's seat belt, the seat
belt and Top Tether strap, or lower anchors
and Top Tether strap, fully in accordance with the child seat manufacturer's instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following impor-
tant information when circumstances require you to place a child in the front-passenger
seat:
R Your vehicle is equipped with air bag tech-
nology designed to deactivate the front-
passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropriate
child restraint on the front-passenger seat.
R A child in a rear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology installed in your vehicle. The only means to eliminate
this risk completely is never to place a child
in a rear-facing child restraint in the front-
passenger seat. We therefore strongly rec- ommend that you always place a child in a
rear-facing child restraint on the rear seat.
R If you install a rear-facing child restraint on
the front-passenger seat, make sure the
00730074 indicator lamp is illuminated,
indicating that the front-passenger front air bag is deactivated. Should the 0073007448
Occupant safetySafety

indicator lamp not illuminate or go out while
the restraint is installed, please check
installation. Periodically check the
00730074 indicator lamp while driving to
make sure that the 00730074indicator
lamp is illuminated. If the 00730074indi-
cator lamp goes out or remains out, do not transport a child on the front-passenger
seat until the system has been repaired.
A child in a rear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger front air bag inflates.
R If you place a child in a forward-facing child
restraint on the front-passenger seat:
- move the seat as far back as possible
- use the proper child restraint recommen-
ded for the age, size and weight of the
child
- secure child restraint with the vehicle's
seat belt according to the child seat man-
ufacturer's instructions
R For children larger than the typical 12-
month-old child, the front-passenger front
air bag may or may not be activated. G
WARNING
If the red 0075SRS warning lamp in the
instrument cluster and the 00730074indica-
tor lamp light up simultaneously, the OCS is
malfunctioning. The front passenger front air
bag will be deactivated in this case. Have the system checked by qualified technicians as
soon as possible. Contact an authorized
Mercedes-Benz Center.
Only have the seat repaired or replaced at an
authorized Mercedes-Benz Center.
In order to ensure proper operation of the air
bag system and OCS:
R Sit with the seat belt properly fastened in a
position that is as upright as possible with
your back against the seat backrest.
R When seated, a passenger should not posi-
tion him/herself in such a way as to cause the passenger's weight to be lifted from the seat cushion as this may result in the OCS
being unable to correctly approximate the
passenger's weight category.
R Read and observe all warnings in this chap-
ter. 0043
PASSENGER AIR BAG OFF indicator lamp
If the SmartKey is removed from the ignition
lock or is in position 0, PASSENGER AIR BAG
OFF indicator lamp 0043does not light up.
The Occupant Classification System (OCS)
categorizes the occupant on the front-
passenger seat using a weight sensor.
The front-passenger front air bag is deactiva-
ted automatically for certain weight catego-
ries.
The PASSENGER AIR BAG OFF indicator lamp
shows you the current status.
The system does not deactivate:
R the side impact air bag
R the window curtain air bag
R the Emergency Tensioning Devices
To be classified correctly, the front passenger
must sit:
R with the seat belt fastened correctly
R in a position that is as upright as possible
with their back against the seat backrest
R with their feet on the floor
The OCS weight sensor reading is affected if
the occupant's weight is transferred, e.g. by
leaning on the armrest.
