Restraint system: introduction
The restraint system reduces the risk of vehi-
cle occupants coming into contact with parts of the vehicle's interior in the event of an
accident. The restraint system can also
reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system comprises:
R Seat belt system
R Air bags
R Child restraint system
R Child seat securing systems
The components of the restraint system work
in conjunction with each other. They can only deploy their protective function if, at all times,
all vehicle occupants:
R have fastened their seat belts correctly
(Y page 44)
R have adjusted their seat and head restraint
properly (Y page 89).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the cor-
rect driver's seat position (Y page 88).
You also have to make sure that an air bag can inflate properly if deployed (Y page 46).
An air bag supplements a correctly worn seat
belt. As an additional safety device, the air
bag increases the level of protection for vehi-
cle occupants in the event of an accident. For example, if, in the event of an accident, the
protection offered by the seat belt is suffi-
cient, the air bags are not deployed. When an
accident occurs, only the air bags that
increase protection in that particular accident
situation are deployed. However, seat belts
and air bags generally do not protect against objects penetrating the vehicle from the out-
side.
Information on restraint system operation
can be found under "Triggering of the Emer-
gency Tensioning Devices and air bags"
(Y page 54). 40

WARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in an accident or trigger unexpectedly, for example.
This poses an increased risk of injury or even fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the 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 for
details. USA only: for further information con- tact our Customer Assistance Center at
1-800-FOR-MERCede s (1‑800‑367 ‑6372). Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and
at regular intervals while the drive system is
running. Therefore, malfunctions can be
detected in good time.
The 6 restraint system warning lamp in
the instrument cluster lights up when the igni- tion is switched on. It goes out no later than afew seconds after the vehicle is started. The
components of the restraint system are in
operational readiness. A malfunction has occurred if the
6
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 drive system running
R lights up again while the drive system is
running G
DANGER
If the restraint system is malfunctioning, indi- vidual restraint system components may be
triggered unintentionally or might not be trig-
gered at all in the event of an accident with a high rate of vehicle deceleration. This could
affect Emergency Tensioning Devices or air
bags, for example. The vehicle's high-voltage
electrical system may also not be deactivated
as intended in the event of an accident. You
could suffer an electric shock if you touch the damaged components of the vehicle's high-
voltage electrical system. This poses an
increased risk of injury or even fatal injury.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop. Immediately switch off the ignition
and remove the SmartKey from the ignition
lock after an accident. PASSENGER AIR BAG indicator lamp

The indicator lamps display the status of the
front-passenger front air bag.
R PASSENGER AIR BAG ON lights up: 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.
R PASSENGER AIR BAG OFF lights up: the
front-passenger front air bag is deactiva-
ted. It will then not be deployed in the event of an accident.
Depending on the person in the front-
passenger seat, the front-passenger front air
bag must either be deactivated or enabled;
see the following 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
installed child restraint system, and the age and size of the child. Therefore, be sure to
observe the notes on the "Occupant Clas-
sification System (OCS)" (Y page 49) and
on "Children in the vehicle" (Y page 56).
There you will also find instructions on rear-
ward and forward-facing child restraint sys- tems on the front-passenger seat.
R All other persons: depending on the clas-
sification of the person in the front-
passenger seat, the front-passenger front
air bag is enabled 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 occu-
pants in the event of an accident or the vehi-
cle rolling over. This reduces the risk of vehi- cle occupants coming into contact with parts
of the vehicle interior or being ejected from the vehicle. Furthermore, the seat belt helps
to keep the vehicle occupant in the best posi-
tion in relation to the air bag.
The seat belt system comprises:
R Seat belts
R Emergency Tensioning Devices for the
front seat belts and the outer seat belts in
the rear
R Seat belt force limiters for the front seat
belts and the outer seat belts in the rear
If the seat belt is pulled out of the belt outlet quickly or with a jerky movement, the belt
retractor locks. The belt strap cannot be
extracted any further.
The Emergency Tensioning Device tightens
the seat belt in an accident, pulling the belt
close against the body. However it does not
pull the vehicle occupant back in the direction
of the backrest.
The Emergency Tensioning Device does not
correct an incorrect seat position or the rout- ing of an incorrectly fastened seat belt.
When triggered, a seat belt force limiter helps
to reduce the force exerted by the seat belt on
the vehicle occupant.
The seat belt force limiters for the front seats
are synchronized with the front air bags,
which absorb part of the deceleration force.
This can reduce the force exerted on the vehi- cle occupants during an accident.
! If the front-passenger seat is unoccupied,
do not insert the belt tongue into the buckle of the front-passenger seat. This may oth-
erwise lead to the triggering of the Emer-
gency Tensioning Device in the event of anaccident, which will then need to be
replaced.
Important safety notes The use of seat belts and child restraint sys-
tems is required by law in:
R all 50 states
R the U.S. territories 42
Occupant safetySafety

The shoulder section of the seat belt must
always be routed across the center of the
shoulder. Adjust the belt outlet if necessary.
X To raise: slide the belt outlet upwards.
The belt outlet will engage in various posi-
tions.
X To lower: hold belt outlet release ?and
slide belt outlet downwards.
X Let go of belt outlet release ?in the
desired position and make sure that the
belt outlet engages.
All seat belts except the driver's seat belt are equipped with a special seat belt retractor tosecurely fasten child restraint systems in the
vehicle. Further information can be found
under "Special seat belt retractor"
(Y page 57).
Seat belt for the center rear seat If the left-hand rear seat backrest is folded
down and back up again, the rear center seat
belt may lock. The seat belt can then not be
pulled out.
X To release the rear center seat belt: pull
the seat belt out approximately 1 in
(25 mm) at the belt outlet on the backrest
and then release it again.
The seat belt is retracted and released.
Releasing seat belts !
Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door, the door trim panel and the seat belt. Dam-
aged seat belts can no longer fulfill their
protective function and must be replaced.
Visit a qualified specialist workshop. X

Belt warning for the driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is a reminder that all vehicle
occupants must wear their seat belts. It may
light up continuously or flash. In addition,
there may be a warning tone.
Regardless of whether the driver's seat belt
has already been fastened, the 7seat belt
warning lamp lights up for six seconds each
time the drive system is started. If the front
doors are closed and the driver or front-
passenger seat belt has not been fastened,
the 7 seat belt warning lamp lights up
again after the six seconds. As soon as the
driver's and front-passenger seat belts are
fastened or a front door is opened again, the
7 seat belt warning lamp goes out.
If the driver's seat belt is not fastened after
the drive system is started, an additional
warning tone will sound. The warning tone Occupant safety

However, it does not protect the chest or
arms.
In the event of a side impact, the window cur-
tain air bag 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 window curtain air bag may be
deployed in other accident situations
(Y page 54). Occupant Classification System
(OCS)
Introduction The Occupant Classification System (OCS)
categorizes the person in the front-passenger
seat. Depending on that result, the front-
passenger front air bag is either enabled or
deactivated.
The system does not deactivate:
R the side impact air bag
R the window curtain air bag
R the Emergency Tensioning Devices
Prerequisites To be classified correctly, the front passenger
must sit:
R with the seat belt fastened correctly
R in an almost upright position with their
back against the seat backrest
R with their feet resting on the floor, if possi-
ble
If the front passenger does not observe these
conditions, OCS may produce a false classi-
fication, e.g. because the front passenger:
R transfers their weight by supporting them-
selves on a vehicle armrest
R sits in such a way that their weight is raised
from the seat cushion
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
be sure to observe the correct positioning of the child restraint system. Never place
objects under or behind the child restraint
system, e.g. cushions. 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 lie as flat as possible against the
backrest of the front-passenger seat.
The child restraint system must not touch the
roof or be subjected to a load by the head
restraint. Adjust the angle of the seat back-
rest and the head restraint position accord-
ingly.
Only then can OCS be guaranteed to function correctly. Always observe the child restraint
system manufacturer's installation instruc-
tions.

Deployment of Emergency Tensioning
Devices and air bags
Important safety notes G
WARNING
The air bag parts are hot after an air bag has
been deployed. There is a risk of injury.
Do not touch the air bag parts. Have a
deployed air bag replaced at a qualified spe-
cialist workshop as soon as possible. G
WARNING
A deployed air bag no longer offers any pro-
tection and cannot provide the intended pro-
tection in an accident. There is an increased
risk of injury.
Have the vehicle towed to a qualified special- ist workshop in order to have a deployed air
bag replaced.
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. G
WARNING
Pyrotechnic Emergency Tensioning Devices
that have been deployed are no longer opera- tional and are unable to perform their inten-
ded protective function. This poses an
increased risk of injury or even fatal injury.
Therefore, have pyrotechnic Emergency Ten-
sioning Devices which have been triggered
immediately replaced at a qualified specialist workshop.
If Emergency Tensioning Devices are trig-
gered or air bags are deployed, you will hear a
bang, and a small amount of powder may also be released. The 6restraint system warn-
ing lamp lights up.
Only in rare cases will the bang affect your
hearing. The powder that is released gener-
ally does not constitute a health hazard, but it may cause short-term breathing difficulties in
people with asthma or other respiratory prob-
lems. To avoid this, you may wish to get out of
the vehicle or open the windows as soon as it is safe to do so.
Air bags and pyrotechnic Emergency Tension-
ing Devices (ETDs) contain perchlorate mate- rial, which may require special handling and
regard for the environment. National guide-
lines must be observed during disposal. In
California, see www.dtsc.ca.gov/
HazardousWaste/Perchlorate/
index.cfm .
Method of operation During the first stage of a collision, the
restraint system control unit evaluates impor-
tant physical data relating to vehicle deceler- ation or acceleration, such as:
R duration
R direction
R intensity
Based on the evaluation of this data, the
restraint system control unit triggers the
Emergency Tensioning Devices during a fron- tal or rear collision.
An Emergency Tensioning Device can only be
triggered, if:
R the ignition is switched on
R the components of the restraint system are
operational; see "Restraint system warning
lamp" (Y page 41)
R the belt tongue is engaged in the buckle on
the respective front-passenger seat
The Emergency Tensioning Devices in the
rear compartment are triggered independ-
ently of the lock status of the seat belts.
If the restraint system control unit detects a
more severe accident, further components of the restraint system are activated independ-
ently of each other in certain frontal collision
situations: 54
