Occupant safety
43In particular, work relevant to safety or on
safety-related
systems must be carried out
at a qualified specialist workshop. If this
work is not carried out correctly, the oper-
ating safety of your vehicle may be affec-
ted. There is a risk of an accident and injury. SRS (Supplemental Restraint System)
The SRS reduces the risk of occupants com-
ing into contact with the vehicle's interior in
the event of an accident. It can also reduce
the forces to which occupants are exposed
during an accident.
The SRS consists of:
R 1 warning lamp
R belt tensioners
R belt force limiters
R Airbags
1 warning lamp The SRS functions are checked regularly
when you turn on the ignition and when the
engine

is running. Malfunctions can therefore
be detected in good time. The 1 warning lamp in the instrument
cluster

lights up when the ignition is switched
on. It goes out no later than a few seconds
after the engine is started. G
Risk of injury
If SRS is malfunctioning, individual systems
may be activated unintentionally or not be
triggered in the event of an accident with
heavy braking.
A malfunction has occurred if the 1
warning lamp:
R does

not light up when you switch on the
ignition
R does not go out after the engine has been
running for a few seconds
R lights up again once the engine is running
In this case, have SRS checked immedi-
ately at a qualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags In the event of a collision, the sensor in the
airbag

control unit evaluates important phys-
ical data such as duration, direction and force
of the vehicle deceleration or acceleration.
Based on the evaluation of this data and depending on the vehicle's rate of longitudi-
nal deceleration in a collision, in the first
stage the airbag control unit pre-emptively
triggers the belt tensioners.
i
The

front belt tensioners can only be trig-
gered if the belt tongue is correctly
engaged in the seat belt buckle.
The front airbags are only deployed if there is
an even higher rate of vehicle deceleration in
a longitudinal direction.
Vehicles fitted with adaptive, dual-stage front
airbags: when the first deployment threshold
is reached, the front airbag is filled with
enough gas to reduce the risk of injuries. The
front airbag is only fully inflated if a second
threshold is reached within a few millisec-
onds due to the control unit having detected
further deceleration.
Criteria for triggering belt tensioners and
airbags
In the first stage of a collision, the airbag con-
trol unit evaluates the duration and direction
of vehicle acceleration or deceleration in
order to determine whether it is necessary to
trigger the belt tensioner and/or airbag.
The belt tensioner and airbag triggering
thresholds are variable and are adapted to the
rate of deceleration of the vehicle. This proc- Safety

ess is pre-emptive in nature as the airbag
must
be deployed during – and not at the end
of – the collision.
i Airbags are not deployed in all types of
accidents. They are controlled by complex
sensor technology and evaluation logic.
This process is pre-emptive in nature as
airbag deployment must take place during
the impact and must be adapted to provide
calculated, additional protection for the
vehicle occupants. Not all airbags are
deployed in an accident.
The different airbag systems work inde-
pendently of each other. However, the
deployment of each individual system will
depend on the type of accident determined
by the control system in the first stages of
the collision (head-on collision, side impact
and overturn) and the extent of the acci-
dent (in particular, the vehicle's rate of
deceleration or acceleration).
The rate of vehicle deceleration or accelera-
tion and the direction of the force are basi-
cally determined by:
R the distribution of forces during the colli-
sion
R the collision angle R
the deformation characteristics of the vehi-
cle
R the characteristics of the object with which
the vehicle has collided, e.g. the other vehi-
cle
Factors which can only be seen and measured
after the collision has taken place do not play
a decisive role in the deployment of an airbag,
nor do they provide an indication of it.
The vehicle may be deformed significantly,
e. g. on the bonnet or the wing, without an
airbag being deployed. This happens if only
parts which are relatively easily deformed are
affected and the necessary deceleration does
not occur. Conversely, airbags may be
deployed even though the vehicle suffers only
minor deformations. This is the case if, for
example, very rigid vehicle parts such as lon-
gitudinal body members are affected and suf-
ficient deceleration occurs as a result.
Belt tensioners, belt force limiters The front seat belts and the outer seat belts
in

the rear are equipped with belt tensioners.
! Do not engage the seat belt tongue in the
buckle on the front-passenger seat if the
seat is not occupied. Otherwise the belt tensioner could be activated in an emer-
gency.
If the seat belt is also equipped with a belt
force limiter, the force exerted by the seat
belt on the seat occupant is reduced.
Belt tensioners tighten the seat belts in an
accident,

pulling them close against the body.
i Belt tensioners do not correct incorrect
seat positions or incorrectly fastened seat
belts.
Belt tensioners do not pull occupants back
towards the backrest.
The front belt force limiters are synchronised
with the front airbags, which spread the
forces exerted by the belt force limiters on
the occupant over a greater area.
When the ignition is switched on, the belt ten-
sioner is triggered:
R only if the restraint systems are operational
(the 1 warning lamp lights up after the
ignition is switched on and goes out once
the engine is running)(Y page 43)
R for each three-point seat belt in the front of
the vehicle when the belt tongue is
engaged in the buckle

sion if the vehicle decelerates or acceler- Safety

ates rapidly in a longitudinal direction
during the initial stages of the collision
R In certain situations if the vehicle over-
turns, if the system determines that it can
provide additional protection
When the belt tensioners are triggered, you
will hear a bang, which will not cause any
harm to your hearing, and a small amount of
powder
may also be released. The 1 warn-
ing lamp lights up. G
Risk of injury
If the seat belt tensioners have been trig-
gered, they provide no additional protec-
tion in the event of another accident.
Therefore,

have belt tensioners which have
been triggered replaced at a qualified spe-
cialist workshop.
Comply with safety regulations when dis-
posing of belt tensioners. Any Mercedes-
Benz Service Centre can provide details of
these regulations.
Airbags Airbag deployment slows down and restricts
the movement of the vehicle occupant.
When

the airbags are deployed, you will hear
a bang, which will not cause any harm to your hearing, and a small amount of powder may
also be released. The
1 warning lamp
lights up.
The SRS/AIRBAG symbol indicates the loca-
tion of the airbags. G
Risk of injury
Airbags provide additional protection; they
are not, however, a substitute for the seat
belts.
Observe the following notes to reduce the
risk of serious or even fatal injury if an air-
bag is deployed:
R Vehicle occupants — in particular preg-
nant woman — must wear their seat belt
correctly at all times and lean back
against their backrest, which should be
positioned

as close to the vertical as pos-
sible. The head restraint must support
the back of the seat occupant's head at
about eye level.
R Always secure children less than
1.50 m tall or under 12 years of age in
suitable child restraint systems.
R All vehicle occupants must select a seat
position that is as far away from the air-
bag as possible. The driver's seat posi-
tion must allow the vehicle to be driven safely. The driver's chest should be as far
away

from the middle of the driver's front
airbag cover as possible.
R Move the front-passenger seat as far
back as possible, in particular, if a child
is secured in a child restraint system on
the seat.
R Vehicle occupants – in particular, chil-
dren – must not lean their head into the
area of the window in which the sidebag/
windowbag is deployed.
R Rearward-facing child restraint systems
must not be fitted to the front-passenger
seat unless the front-passenger front air-
bag has been disabled. On the front-
passenger seat, the front-passenger
front airbag is only deactivated if a child
restraint system with automatic child
seat recognition is fitted to the front-
passenger seat*. The 5 PASSENGER
AIRBAG OFF warning lamp must be lit
constantly.
If either the rearward-facing child
restraint system or the front-passenger
seat* of your vehicle does not have auto-
matic child seat recognition, children
must be secured in a child restraint sys- Safety

independently of the belt tensioners
R if the vehicle overturns, but only if the sys-
tem detects high vehicle deceleration in a
lateral direction and determines that side-
bag deployment can offer additional pro-
tection to that provided by the seat belt
Windowbags
The purpose of the windowbags is to enhance
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.
The windowbags are integrated into the side
of the roof frame and run from the front door
(A-pillar) to the rear door (C-pillar).1 Windowbag Windowbags
1 are deployed:
R at the start of an accident with a high rate
of vehicle acceleration or deceleration in a
lateral direction
R on the side on which an impact occurs
R independently of the front airbags
R regardless of whether the front-passenger
seat is occupied
R if the vehicle overturns and the system
determines that windowbag deployment

intervenes in the event of:
R emergency braking situations, e.g. if BAS
Brake Assist intervenes
R critical situations involving driving dynam-
ics, e.g. if the vehicle oversteers or under-
steers significantly due to physical limits
being exceeded If you are driving faster than approximately
30 km/h, PRE-SAFE
®
takes the following
measures in the aforementioned situations:
R It tensions the front seat belts.
R Vehicles with memory functions*: it
adjusts the front-passenger seat if this is in
an unfavourable position.
R If the vehicle skids, it closes the sliding/
tilting sunroof* and side windows so that
only a small gap remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
releases
the belt pretensioning. You can then reverse
all settings made by PRE-SAFE ®
again.
If the seat belts are not released:
X Move the backrest or the seat back slightly
until the belt tension is reduced.
The locking mechanism releases.
G Risk of injury
Make sure when adjusting the seat that
nobody can become trapped.
! Make sure that there are no objects in the
footwell or behind the seats when adjusting
the seats. You could otherwise damage the
seats and the objects.

Occupant safety
49NECK-PRO head restraint
NECK-PRO head restraints are designed to
increase protection to the driver's and front-
passenger's head and neck. To this end, the
head restraints on the driver's and front-
passenger seats are moved forwards and
upwards
in the event of a rear-end collision in
the direction of travel. This provides better
head support. G
Risk of injury
Head restraint covers prevent the NECK-
PRO head restraints from triggering cor-
rectly. Consequently, the NECK-PRO head
restraints

cannot provide the intended level
of protection. Do not use head restraint
covers.
If the NECK-PRO head restraints are triggered
in an accident, you must reset the head
restraints on the driver's and front-passenger
seats (Y page 269). Head restraints that have
been triggered are tilted forwards. Children in the vehicle
If a child is riding in your vehicle, secure the
child using a child restraint system appropri-
ate to the size and age of the child and
approved for Mercedes-Benz vehicles. Pref-
erably,

you should fit the restraint system on
a suitable rear seat. Preferably, you should fit
it to a suitable rear seat. Make sure that the
child is strapped in throughout the trip.
You can obtain information about the correct
child restraint system from any Mercedes-
Benz Service Centre.
i It is advisable to use Mercedes-Benz care
products to clean child restraint systems.
You can obtain information about this from
any Mercedes-Benz Service Centre. G
Risk of injury
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system. The children could injure
themselves on parts of the vehicle. They
could also be seriously or even fatally
injured by prolonged exposure to extreme
heat or cold.
Do

not expose the child restraint system to
direct sunlight. The metallic parts of the child restraint system could heat up and the
child could be burned by them.
If

the children open the door other persons
could be injured. They could get out and
injure themselves or be injured by a passing
vehicle.
You should also observe the information on
HOLD; see the index. G
Risk of injury
An unsecured or incorrectly positioned load
increases the risk of injury to the child in
the event of:
R an accident
R a braking manoeuvre
R a sudden change of direction
Do not carry heavy or hard objects inside
the vehicle unless they are secured. You
will

find further information under "Loading
guidelines" in the index.
Child restraint systems Mercedes-Benz recommends that you only
use the child restraint systems listed on
(Y page 54). Safety
