Occupant safety
Introduction to the restraint system
The restraint system can reduce 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:
RSeat belt system
RAir bags
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:
Rhave fastened their seat belts correctly
(Ypage 38)
Rhave adjusted their seat properly
(Ypage 75).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position (
Ypage 75). You also have to make sure that an air bag can
inflate properly if deployed (
Ypage 40).
An air bag supplements a correctly worn seat
belt. As an additional safety device, the air bag
increases the level of protection for vehicle
occupants in the event of an accident. For exam-
ple, if, in the event of an accident, the protection
offered by the seat belt is sufficient, the air bags are not deployed. When an accident occurs, only
the air bags that increase protection in that par-ticular accident situation are deployed. How-
ever, seat belts and air bags generally do not
protect against objects penetrating the vehicle
from the outside.
Information on restraint system operation can
be found under "Triggering of the Emergency
Tensioning Devices and air bags" (
Ypage 46).
See "Children in the vehicle" for information on
infants and children traveling with you in the
vehicle restraint systems for infants and chil-
dren (
Ypage 49).
Important safety notes
GWARNING
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-MERCedes (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 engine is running.
Therefore, malfunctions can be detected in
good time.
Occupant safety35
Safety
Z
The6 restraint system warning lamp in the
instrument cluster lights up when the ignition is
switched on. It goes out no later than a few sec-
onds after the engine is started. The compo-
nents of the restraint system are in operational
readiness.
A malfunction has occurred if the 6restraint
system warning lamp:
Rdoes not light up after the ignition is switched
on
Rdoes not go out after a few seconds with the
engine running
Rlights up again while the engine is running
GWARNING
If restraint system is malfunctioning, restraint
system components may be triggered unin-
tentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emer- gency Tensioning Device or air bag, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.
PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lamp :and
PASSENGER AIR BAG OFF indicator lamp ;are
part of the Occupant Classification System
(OCS).
The indicator lamps display the status of the
front-passenger front air bag.
RPASSENGER 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.
RPASSENGER AIR BAG OFF lights up: the front-
passenger front air bag is deactivated. It will
then not be deployed in the event of an acci-
dent.
Depending on the person in the front-passenger
seat, the front-passenger front air bag must
either be deactivated or enabled; see the fol-
lowing points. You must make sure of this both
before and during a journey.
RChildren in a child restraint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the instal-
led child restraint system, and the age and
size of the child. Therefore, be sure to observe
the notes on the "Occupant Classification
System (OCS)" (
Ypage 42) and on "Chil-
dren in the vehicle" (Ypage 49). There you
will also find instructions on rearward and
forward-facing child restraint systems on the
front-passenger seat.
RAll other persons: depending on the classi-
fication of the person in the front-passenger
seat, the front-passenger front air bag is ena-
bled or deactivated (
Ypage 42). Be sure to
observe the notes on "Seat
belts“ (
Ypage 36) and "Air bags"
(Ypage 40). 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 occupants
in the event of an accident or the vehicle rolling
over. This reduces the risk of vehicle occupants
coming into contact with parts of the vehicle
interior or being ejected from the vehicle. Fur-
thermore, the seat belt helps to keep the vehicle
occupant in the best position in relation to the
air bag.
The seat belt system comprises:
RSeat belts
REmergency Tensioning Devices and seat belt
force limiters
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 extrac-
ted any further.

XIf necessary, pull upwards on the shoulder
section of the seat belt to tighten the belt
across your body.
In order to attach the child restraint system
securely in the vehicle, the seat belt on the front-
passenger seat is equipped with a special seat
belt retractor. Further information on the "Spe-
cial seat belt retractor" (
Ypage 49).
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. Damaged seat belts
can no longer fulfill their protective function
and must be replaced. Visit a qualified spe-
cialist workshop.

Seat belt adjustment
The seat-belt adjustment is an integral part of
the PRE-SAFE®convenience function. This func-
tion adjusts the driver's and front-passenger
seat belt to the upper body of the occupants.
The belt strap is tightened slightly when:
Rthe belt tongue is engaged in the buckle and
Rthe ignition is switched on
The seat-belt adjustment will apply a certain
retraction force if any slack is detected between
the vehicle occupant and the seat belt. Do not
hold on to the seat belt tightly while it is adjust-
ing.
You can activate and deactivate the seat-belt
adjustment function using the multimedia sys-
tem. Information on activating and deactivating
the seat-belt adjustment function can be found
in the Digital Operator's Manual.
Belt warning for the driver and front
passenger
The 7 seat belt warning lamp in the instru-
ment cluster is a reminder that all occupants
must fasten their seat belts. It may light up con- tinuously 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 warn-

Prerequisites
To be classified correctly, the front passenger
must sit:
Rwith the seat belt fastened correctly
Rin an almost upright position with their back
against the seat backrest
Rwith their feet resting on the floor, if possible
If the front passenger does not observe these
conditions, OCS may produce a false classifica-
tion, e.g. because the front passenger:
Rtransfers their weight by supporting them-
selves on a vehicle armrest
Rsits in such a way that their weight is raised
from the seat cushion
If you 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.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint sys-
tem manufacturer's installation instructions.

:PASSENGER AIR BAG ON indicator lamp
;PASSENGER AIR BAG OFF indicator lamp
The indicator lamps inform you whether the
front-passenger front air bag is deactivated or
enabled.
XPress the Start/Stop button once or twice, or turn the SmartKey to position 1or 2in the
ignition lock.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul-
taneously for approximately six seconds. The indicator lamps display the status of the
front-passenger front air bag.
RPASSENGER 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.
RPASSENGER AIR BAG OFF lights up: the front-
passenger front air bag is deactivated. It will
then not be deployed in the event of an acci-
dent.
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 instrument clus- ter (
Ypage 175). When the front-passenger
seat is occupied, always pay attention 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 journey.
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.

continue to perform their protective function for
the vehicle occupants in the event of a crash.
GWARNING
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.
An electric motor is used by PRE-SAFE
®to trig-
ger the tightening of the seat belt in hazardous
situations. This procedure is reversible.
If Emergency Tensioning Devices are triggered
or air bags are deployed, you will hear a bang,
and a small amount of powder may also be
released. The 6restraint system warning
lamp lights up.
Only in rare cases will the bang affect your hear-
ing. The powder that is released generally does
not constitute a health hazard, but it may cause
short-term breathing difficulties in people with
asthma or other respiratory problems. 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 Tensioning
Devices (ETDs) contain perchlorate material,
which may require special handling and regard
for the environment. National guidelines 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 important physi-
cal data relating to vehicle deceleration or accel-
eration, such as:
Rduration
Rdirection
Rintensity
Based on the evaluation of this data, the
restraint system control unit triggers the Emer-
gency Tensioning Devices during a frontal or
rear collision. An Emergency Tensioning Device can only be
triggered, if:
Rthe ignition is switched on
Rthe components of the restraint system are
operational; see "Restraint system warning
lamp" (
Ypage 35)
Rthe belt tongue has engaged in the belt buckle
of the respective seat
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:
RFront air bags as well as driver's and front-
passenger knee bags
RSide impact air bag and window curtain air
bag, if the system determines that deploy-
ment can offer additional protection to that
provided by the seat belt
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 indicator lamp is lit.
Observe the information on the PASSENGER AIR
BAG indicator lamps (
Ypage 36).
Your vehicle has two-stage front air bags. During the fi
rst 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 propellant gas if a sec-
ond deployment threshold is reached within a
few milliseconds.
The activation threshold of the Emergency Ten-
sioning Devices and the air bag are determined
by evaluating the rate of vehicle deceleration or
acceleration which occurs at various 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 acceleration
and the direction of the force are essentially
determined by:
Rthe distribution of forces during the collision
Rthe collision angle
Rthe deformation characteristics of the vehicle
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 deci-
sive role in the deployment of an air bag, Nor do
