Airbags and belt tensioners could fail to
deploy or be triggered in an accident despite
the deceleratio nforce being sufficient to trig-
ger the systems, or could be triggered unin-
tentionally. For this reason, never make any
modifications to the restraint systems.
Therefore, you must not tamper with elec-
tronic components or their software. SRS (Supplemental Restraint System)
Introduction SRS reduces the risk of occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
effect of the forces to which occupants are
subjected during an accident.
SRS consists of:
R the 6 SRS warning lamp
R airbags
R airbag control unit (with crash sensors)
R belt tensioners
R belt force limiters
SRS warning lamp SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 6 SRS 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 may not
be triggered in the event of an accident with
a high rate of vehicle deceleration. A malfunction has occurred if:
R
the 6 SRS warning lamp does not light
up when the ignition is switched on.
R the engine is running and the 6SRS
warning lamp does not go out after a few
seconds.
R the engine is running and the 6SRS
warning lamp lights up again.
In this case, have SRS checked immediately
at a qualified specialist workshop. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose.
In particular, work relevant to safety or on
safety-related systems must be carried out at
a qualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags During the first stage of a collision, the airbag
control unit evaluates important physical
data relating to vehicle deceleration or accel-
eration, such as
R
duration
R direction
R magnitude
Based on the evaluation of this data, the air-
bag control unit pre-emptively triggers the
belt tensioners in the first stage.
i The front belt tensioners can only be trig-
gered if the seat belt tongues on the front
seats are correctly engaged in the seat belt
buckles.
If there is an even higher rate of vehicle decel-
eration or acceleration in a longitudinal direc-
tion, the front airbags are also deployed.
Your vehicle has adaptive, two-stage front air-
bags. The airbag control unit evaluates vehi-
cle deceleration or acceleration in the event
of a collision. When the first deployment
threshold is reached, the front airbag is filled
with enough propellant gas to reduce the risk
of injuries. The front airbag is fully deployed
if a second deployment threshold is exceeded
within a few milliseconds. Occupant safety
35Safety Z

The belt tensioner and airbag triggering
thresholds are variable and are adapted to the
rate of deceleration or acceleration of the
vehicle. This process is pre-emptive in nature.
The triggering process must take place in
good time at the start of the collision.
i Not all airbags are deployed in an acci-
dent. The different airbag systems work
independently of each other.
How the airbag system works is deter-
mined by the severity of the accident detec-
ted, especially the vehicle deceleration or
acceleration, and the apparent type of acci-
dent:
R head-on collision
R side impact
R overturn
The rate of vehicle deceleration or accelera-
tion and the direction of the force are essen-
tially 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
Factors which can only be seen and measured
after a collision has occurred do not play a
decisive role in the deployment of an airbag
nor do they provide an indication of airbag
deployment.
The vehicle may be deformed significantly,
e.g. the bonnet or the wing, without an airbag
being deployed. This is the case if only parts
which are relatively easily deformed are affec-
ted and the deployment threshold is not
reached. Conversely, airbags may be
deployed even though the vehicle suffers only
minor deformation .This is the case if, for
example, very rigid vehicle parts such as lon-
gitudinal body members are hit and sufficient
deceleration occurs as a result. Airbags
Important safety notes Airbag deployment slows down and restricts
the movement of the vehicle occupant.
If the airbags 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. The 6SRS warning lamp
lights up.
The airbag installation locations are identified
by the AIRBAG symbol. G
Risk of injury
Airbags provide additional protection; they
are not, however, a substitute for seat belts.
Observe the following notes to reduce the risk
of serious or even fatal injury caused by airbag
deployment:
R All vehicle occupants –inparticular, preg-
nant women – must wear their seat belt
correctly at all times and lean back against
the backrest, which should be positioned
as close to the vertical as possible. The
head restraint must support the back of the
head at about eye level.
R Always secure childre nless than 1.50mt all
and unde r12years of age in suitable child
restraint systems.
R All vehicle occupants must select a seat
position that is as far away from the airbag
as possible. The driver's seat position must
allow the vehicle to be driven safely. The
driver's chest should be as far away from
the centre of the driver's airbag cover as
possible.
R Move the front-passenger seat as far back
as possible. This is especially important if
you have secured a child in a child restraint
system on the front-passenger seat.
R Vehicle occupants –inparticular, children
–m ust no tlean their heads into the area of
the window in which the sidebag/window-
bag is deployed. 36

the vehicle occupants on the side of the vehi-
cle on which the impact occurs.
The windowbags are integrated into the side
of the roo
fframe and deploy in the area
extending from the front door (A-pillar) to the
rear door (C-pillar). Windowbags
:are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleratio noraccelera-
tion, e.g. in a side impact
R regardless of whethe rthe front-passenger
seat is occupied
R independently of seat belt use
R if the vehicle overturns and the system
determines that windowbag deployment
can offer additional protection to that pro-
vided by the seat belt
R independently of the front airbags PRE-SAFE
®
(preventative occupant
protection)
PRE-SAFE ®
takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations.
PRE-SAFE ®
intervenes:
R in emergency braking situations, e.g. if BAS
is activated or intervenes powerfully in vehicles with DISTRONIC PLUS, BAS PLUS
or PRE-SAFE ®
Brake
R if the radar sensor system detects an immi-
nent danger of collision in certain situa-
tions (on vehicles with DISTRONIC PLUS)
R in critical situations involving driving
dynamics, e.g. if the vehicle oversteers or
understeers significantly due to physical
limits being exceeded or if the vehicle
swerves to avoid an obstacle at a speed of
over 140 km/h.
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R vehicles with the memory function: under
accident conditions, it adjusts the front-
passenger seat if it is in an unfavourable
position.
R vehicles with a multicontour seat or an
active multicontour seat: the air pressure
in the side bolsters on the seat cushion and
the side bolsters on the backrest is
increased.
R if the vehicle skids, the sliding sunroof/
panorama sliding sunroof and the side win-
dows are closed so that only a small gap
remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning. The air pressure in the
side bolsters on the multicontour seat/active
multicontour seat is reduced again. All set-
tings made by PRE-SAFE ®
can then be
reversed.
If the seat belts are not released:
X Move the backrest or seat back slightly, but
only when the vehicle is stationary.
The belt pretensioning is reduced and the
locking mechanism releases. G
Risk of injury
When adjusting the seat, make sure that
nobody can become trapped. 40

Important safety notes Seat belts are the most effective means of
restraining the movement of vehicle occu-
pants in the event of an accident. This
reduces the ris
kofvehicle occupants coming
into contact with parts of the vehicle interior. G
Risk of injury
A seat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, cannot perform its intended
protective function. Under certain circum- stances, this could cause severe or even fatal
injuries in the event of an accident.
Make sure that all occupants –inparticular,
pregnant women – wear their seat belt cor-
rectly at all times.
R The seat belt must fit snugly on your body
and must no tbe twisted. Therefore, avoid
wearing bulky clothing, e.g. a winter coat.
The shoulder belt section must be routed
across the centre of your shoulder – on no
account across your neck or under your
arm –and pulled tight against your upper
body .The lap belt must always pass across
your lap as low down as possible, i.e. over
your hip joints –not across your abdomen.
If necessary, push down the belt strap
slightly and then retighten it in the roll-up
direction.
R Do not route the belt strap across sharp
edges or fragile objects, especially if these
are located on or in your clothing, e.g. spec-
tacles, pens, keys, etc. The seat belt strap
could be damaged and tear in an accident,
and you or other vehicle occupants could
be injured.
R Only one person should use each seat belt
at any one time. Children must never travel
sitting on the lap of other occupants. It
would not be possible to restrain the child
in the event of a sudden change in direc-
tion, braking or an accident .This could
result in severe or even fatal injuries to the
child and other occupants.
R Persons less than 1.50 m tall cannot wear
the seat belts correctly. For this reason,
secure persons less than 1.50 mtall in spe-
cially designed, suitable restraint systems.
R Children less than 1.50 m tall or under 12
years of age canno twear the seat belts
properly. Therefore, they should always be
secured in a suitable child restraint system
on a suitable vehicle seat. You can find
more information under "Children in the
vehicle" in the "Safety" section of the Own-
er's Manual. Follow the manufacturer's 42

The belt strap is tightened slightly when:
R you engage the belt tongue in the belt
buckle and you then turn the key to position
2in the ignition lock.
R the key is in position 2in the ignition lock
and you then engage the belt tongue in the

The seat-belt adjustmen twill apply a certain
tightening force if any slack is detected
between the occupant and the seat belt. Do
not hold on to the seat belt tightly while it is
adjusting. You can switch the seat-belt
adjustment on and off in the on-board com-
puter (Y page 211).

Belt warning for driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is a reminder for all occupants
to fasten their seat belts .Itmay light up con-
tinuously or flash. In addition, there may be a
warning tone.
The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and
the fron tpassenger have fastened their seat
belt .Ift he vehicle is stationary and a door is
opened, the 7seat belt warning lamp
goes out and the warning tone ceases.
For certain countries only: regardless of
whether the driver or the front passenger
have fastened their seat belts, the 7seat
belt warning lamp lights up for six seconds
after the engine is started. It then goes out if
the driver and the front passenger have fas-
tened their seat belts.
i For more information on the 7seat
belt warning lamp, see "Indicator and warn-
ing lamps in the instrumentc luster, seat
belt" (Y page 239).
Rear seat belt status indicator The rear-compartmen
tseat belt status indi-
cator tells you if the rear passengers have
their seat belts fastened.
The rear-compartment seat belt status indi-
cator indicates the rear seat on which the belt
is fastened. 44
Occupant safetySafety

The rear-compartmen
tseat belt status indi-
cator appears in the multifunction display for
around 30 seconds if:
R you drive off and reach a speed of approx-
imately 10 km/h.
R the rear passengers fasten or unfasten
their seat belts while the vehicle is in
motion.
R someone gets in or out of the vehicle and
the vehicle drives off again.
You can also cancel the rear seat belt status
indicator immediately (Y page 215).
i The status indicator for the rear-compart-
ment seat belts is only available for certain
countries.
Belt tensioners, belt force limiters The seat belts are fitted with belt tensioners.
!
If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckle on the front-passenger seat.
Otherwise, the belt tensioner could be trig-
gered in the event of an accident.
The belt tensioners tighten the seat belts in
an accident, pulling them close against the
body.
Belt tensioners do not correct incorrect seat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
If the seat belt is also fitted with a belt force
limiter and this is triggered, the force exerted
by the seat belt on the vehicle occupan tis
reduced.
The front beltf orce limiters are synchronised
with the front airbags, which take on a part of
the deceleration force. Thus, the force exer-
ted on the occupant is distributed over a
greater area. The belt tensioners can only be activated
when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 35).
R the belt tongue is engaged in the buckle on
each of the three-point seat belts in the
front.
The belt tensioners on the seats in the rear
compartment are triggered independently of
the lock status of the seat belts.
The belt tensioners are triggered depending
on the type and severity of an accident:
R in the event of a head-on or rear-end colli-
sion if the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of the impact
R in the event of a side impact, on the side
opposite the impact if the vehicle deceler-
ates or accelerates rapidly in a lateral direc-
tion
R in certain situations if the vehicle overturns
and the system determines that it can pro-
vide additional protection
If the airbags 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. The 6SRS warning lamp
lights up. G
Risk of injury
If the seat belt tensioners have been trig-
gered, they provide no additional protection
in the event of another accident. Therefore,
have belt tensioners which have been trig-
gered replaced at a qualified specialist work-
shop.
Comply with safety regulations when dispos-
ing of belt tensioners. Any Mercedes-Benz
Service Centre can provide details of these
regulations. Occupant safety

Children in the vehicle
Important safety notes
G
Risk of injury
Do no tleave children unsupervised in the
vehicle, even if they are secured in a child
restraint system. They could injure them-
selves on parts of the vehicle. They could also
be seriously or even fatally injured by pro-
longed exposure to extreme heat or cold.
Do not expose the child restraint system to
direct sunlight. Parts of the child restraint sys-
tem could heat up and the child could burn
herself/himself on them.
If a child opens a door, the child or other per-
sons could be injured as a result. They could
get out and injure themselves or be injured by
a passing vehicle.
Also observe the notes on HOLD .Relevant
information can be found in the index. G
Risk of injury
Unsecured or incorrectly positioned loads
increase the risk of injury for children and all
other occupants in the event of:
R an accident
R a braking manoeuvre
R a sudden change of direction
Do not carry heavy or hard objects in the vehi-
cle interior unless they are secured. You will
find further information under "Loading guide-
lines" in the index.
If a child is travelling in your vehicle, secure
the child using a child restraint system which
is appropriate to the size, age and weight of
the child and recommended for Mercedes-
Benz vehicles. You should fit the restraint sys-
tem to a suitable rear seat. Make sure that
the child is secured in achild restraint system
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-Ben zcare
products to clean child restraint systems.
You can obtain informatio nabout this from
any Mercedes-Benz Service Centre. Child restraint systems
Important safety notes Mercedes-Benz recommends that you only
use the child restraint systems listed at
(Y
page 54). G
Risk of injury
To reduce the risk of serious or even fatal
injury to the child in the event of a sudden
change in direction, braking or an accident:
R Children less than 1.5 0mtall and under
twelve years of age must always be secured
in special child restraint systems on a suit-
able vehicle seat .This is necessary
because the seat belts are not designed for
children.
R Do not secure children less than 1.50 mtall
or under twelve years of age on the front-
passenger seat .Exception: the child is
secured in a vehicle with automatic child
sea trecognition on the front-passenger
seat and is secured in achild restraint sys-
tem with automatic child seat recognition.
R If you secure a forward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible.
R Children must never travel sitting on the lap
of another occupant. Due to the forces
which occur in the event of a sudden
change of direction, heavy braking or an
accident, it would not be possible to
restrain the child. The child could be thrown
against parts of the vehicle interior and be
seriously or even fatally injured. G
Risk of injury
The child restraint system cannot perform its
protective function if it is not correctly fitted 46
