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.
Furthermore, the restraint system may also
reduce the forces exerted on the vehicle occu-
pants when an accident occurs.
The restraint system includes:
RSeat belt system
RAir bags
RChild restraint system
RChild seat securing system
The components of the restraint system work in
conjunction with each other. They can only offer
the intended level of protection if all vehicle
occupants:
Rare correctly wearing their seat belts.
(Ypage 43)
Radjust their seat and head restraint properly
(Ypage 91). The driver is also responsible for ensuring that
the steering wheel has been correctly posi-
tioned. Observe the information relating to the
correct driver's seat position (
Ypage 91).
Always ensure the air bag can inflate properly if
deployed (
Ypage 45).
An air bag supplements a correctly fastened
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 the protection already provided by a cor-
rectly fastened seat belt will suffice, the air bags
are not deployed. Furthermore, only the air bags that would increase the degree of protection
afforded to the vehicle occupants in the event of
an accident are deployed. 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 Emergency Ten-
sioning Devices and air bags" (
Ypage 52).
See “Children in the vehicle” for information on
children traveling with you as well as vehicle
restraint systems (
Ypage 56).
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
40Occupant safety
Safety
regular intervals while the engine is running.
Therefore, malfunctions can be detected in
good time.
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 vehicle 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 OFF indicator
lamp
PASSENGER AIR BAG OFF indicator lamp :is
part of the Occupant Classification System
(OCS). The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the front-
passenger front air bag.
If the PASSENGER AIR BAG OFF indicator
lamp:
Ris lit: the front-passenger front air bag is
deactivated. It will then not be deployed in the
event of an accident.
Ris not lit
: 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.
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 48) and on "Chil-
dren in the vehicle" (Ypage 56). 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 48). Be sure to
observe the notes on "Seat
belts“ (
Ypage 41) and "Air bags"
(Ypage 45). 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.
Occupant safety41

Always make sure that the seat-belt extenderis retracted during a journey.
The seat-belt extender for the driver and front
passenger helps you fasten your seat belt. Seat-
belt extender =is extended when the respec-
tive door is closed and the SmartKey is turned to
position 1or 2in the ignition lock.
You can also extend seat-belt extender =with

Rthe belt tongue is not engaged in the seat belt
buckle within 60 seconds.
Rthe respective door is opened.
Rthe SmartKey is turned to position 0in the
ignition lock.
Ryou release the seat backrest and fold it for-
wards.
Rthe front-passenger seat is unoccupied after
approximately five seconds.
If you press seat-belt extender button ?after
this, seat-belt extender =will not extend.
Basic illustration
XAdjust the seat (Ypage 91).
The seat backrest must be in an almost ver-
tical position.
XPull the seat belt smoothly out of seat-belt
extender =and engage belt tongue ;into
belt buckle :.
The seat belt on the driver’s seat and the
front-passenger seat may be tightened auto-
matically, see "Belt adjustment"
(
Ypage 45).
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 belts in the rear
are equipped with a special seat belt retractor.
Further information can be found under "Special
seat belt retractor" (
Ypage 57).
Automatic comfort-install feature
The front seat belts have an automatic comfort-
install feature. The automatic comfort-fit feature
reduces the retraction force of the seat belts.
The seat belts are thus routed more comfortably
for the driver and front passenger.
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.
XPress the release button in the belt buckle,
hold the belt tongue firmly and guide the belt
back.
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 when
the seat-belt extender is retracted 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 switch the seat-belt adjustment on and
off in the on-board computer (
Ypage 196).
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 occu-
pants 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 warn-
ing lamp lights up for six seconds each time the
engine is started. If, after six seconds, the driver
or front-passenger seat belt has not been fas-
tened and the doors are closed, the 7seat
belt warning lamp lights up. As soon as the driv- er's and front-passenger seat belts are fastened
or a front door is opened again, the 7seat
belt warning lamp goes out.
If the driver's seat belt is not fastened after the
engine is started, an additional warning tone will
sound. The warning tone switches off after six
seconds or once the driver's seat belt is fas-
tened.
If the vehicle's speed exceeds 15 mph
(25 km/h) once and the driver's and front-
passenger seat belts are not fastened, a warning tone sounds. A warning tone also sounds with increasing intensity for 60 seconds or until the
driver or front passenger have fastened their
seat belts.
If the driver or front passenger unfasten their
seat belts during the journey, the seat belt warn-
ing is activated again.
iMore information on the 7seat belt
warning lamp can be found under "Warning
and indicator lamps in the instrument cluster,
seat belt" (
Ypage 220).
Air bags
Introduction
The air bag installation point is identified by the
label AIR BAG.
An air bag supplements a correctly fastened
seat belt. However, it is not intended as a sub-
stitute for the seat belt. Air bags provide addi-
tional protection in the event of an accident.
Not all air bags are deployed in an accident. The
various air bag systems work independently of
each other (
Ypage 52).
There is, however, no system available today
that can completely rule out injury or death.
It is also not possible to rule out a risk of injury
caused by an air bag due to the high speed at
which the air bag must be deployed.
Important safety notes
GWARNING
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants:
Rhave fastened their seat belts correctly,
including pregnant women
Rare sitting correctly and maintain the great-
est possible distance to the air bags
Rfollow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
Occupant safety45
Safety
Z
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 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 backrest
and the head restraint position accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint sys-
tem manufacturer's installation instructions.
Occupant Classification System opera-
tion (OCS)
PASSENGER AIRBAG OFF indicator lamp :
indicates whether the front-passenger front air
bag is disabled.
XTurn the SmartKey to position 1or 2in the
ignition lock, or in vehicles with KEYLESS-GO,
press the start/stop button once or twice.
The system carries out a self-diagnosis test.
The PASSENGER AIR BAG OFF indicator lamp
must light up for about six seconds.
The PASSENGER AIR BAG OFF indicator lamp
then shows the status of the front-passenger
front air bag. If the status of the front-passenger
front air bag changes whilst the vehicle is in
motion, an air bag display message may appear
in the instrument cluster (
Ypage 204). Always
observe the PASSENGER AIR BAG OFF indicator
lamp when the front-passenger seat is occu-
pied. Make sure that the status of the front-
passenger front air bag is correct before and
during a journey.
If the PASSENGER AIRBAG OFF indicator
lamp:
Rlights up, the front-passenger front air bag is
disabled. It will then not be deployed in the
event of an accident.
Rdoes not light up, the front-passenger front
air bag is enabled. If, in the case of an acci-
dent, all deployment criteria are met, the
front-passenger front air bag is deployed.
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-
