If there is an even higherr
ate of vehicle decel-
eration or acceleratio ninalongitudinal 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. In the firs tdeployment stage,
the fron tairbag is filled with enough propel-
lant gas to reduce the risk of injuries. The
front airbag is fully deployed if a second
deploymen tthreshold is reached within a few
milliseconds.
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.
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 rate of deceleration is not high.
Conversely, airbags may be deployed even
though the vehicle suffers only minor defor-
mation. This is the case if, for example, very
rigid vehicle parts such as longitudinal body
members are hit, and sufficient deceleration
occurs as a result. 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.
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 Airbags
Important safety notes G
WARNING
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 or unde r12years of age in suit-
able 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. 44
Occupant safetySafety 

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.
R rearward-facing child restraint systems
must not be fitted to the front-passenger
seat unless the front-passenger airbag has
been disabled. On the front-passenger
seat, the front-passenger airbag is disabled
if a child restraint system with a trans-
ponder for automatic child seat recognition
is fitted to the front-passenger seat in a
vehicle equipped with automatic child seat
recognition. The 4PASSENGER AIRBAG
OFF indicator lamp must be continuously
lit.
If the front-passenger seat of your vehicle
does not have automatic child seat recog-
nition, or your rearward-facing child
restraint system does not have a trans-
ponder for automatic child seat recogni-
tion, children must be secured in a child
restraint system on a suitable seat in the
rear. 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 make sure there are no heavy or sharp-
edged objects in the pockets of clothing.
R do not lean forwards, e.g. over the cover of
the driver's/front-passenger front airbag,
particularly when the vehicle is in motion.
R do not put your feet on the dashboard.
R only hold the steering wheel on the outside.
This allows the airbag to be fully deployed.
You could be injured if the airbag is
deployed and you are holding the inside of
the steering wheel.
R do not lean on the doors from inside the
vehicle. R
make sure that there are no people, ani-
mals or objects between the vehicle occu-
pants and the area where the airbags are
deployed.
R do not place any objects between the seat
backrest and the door.
R do not hang any hard objects, e.g. coat
hangers, on the grab handles or coat hooks.
R do not attach accessories, e.g. cup holders,
to the doors.
It is not possible to rule out a risk of injury
being caused by an airbag, due to the high
speed at which the airbag must be deployed. G
WARNING
Airbag functionality can only be assured if the
following parts are not covered and no badges
or stickers are attached to them:
R padded steering wheel boss
R kneebag cover below the steering column
R front-passenger airbag cover
R outer side of fron tseat bolsters
R side trim next to the rear seat backrest
R roof frame cover between the fron tA-pillar
and the C-pillar in the rear compartment G
WARNING
Whe nana irbag deploys, a small amount of
powder is released .The powder may cause
short-term breathing difficulties to persons
suffering from asthma or other pulmonary
conditions.
In order to prevent potential breathing diffi-
culties, you should leave the vehicle as soon
as it is safe to do so. You can also open the
window to allow fresh air to enter the vehicle
interior. The powder does not constitute a
health hazard and does not indicate that there
is a fire in the vehicle. G
WARNING
The airbag parts are hot after the airbag has
been deployed. Do not touch them as you
could burn yourself. Occupant safety
45Safety
Z 

Have the airbags replaced at a qualified spe-
cialist workshop
.Otherwise, occupants are
not protected by the airbags in the event of
another accident.
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.
Front airbags !
Do not place heavy objects on the front-
passenger seat. The system may then
detect that the seat is occupied and if there
is an accident, the restraint systems on the
front-passenger side could be deployed.
Have restraint systems that have been trig-
gered replaced. Driver's airbag
:deploys in front of the
steering wheel; front-passenger front air-
bag ;deploys in front of and above the glove
compartment.
The front airbags increase protection for the
driver's and front-passenger's head and
chest. They are deployed:
R
at the start of an accident with a high rate
of vehicle acceleration or deceleration in a
longitudinal direction
R if the system determines that airbag
deployment can offer additional protection
to that provided by the seat belt
R depending on whether the seat belt is being
used
R independently of other airbags in the vehi-
cle
If the vehicle overturns, the front airbags are
generally not deployed. The front airbags are
deployed if the system detects high vehicle
deceleration in a longitudinal direction.
Vehicles with automatic child seat recog-
nition in the front-passenger seat: front-
passenger airbag is only activated if the sys-
tem determines that the front-passenger seat
is occupied. The 4PASSENGER AIRBAG
OFF indicator lamp on the centre console
does not light up (Y page 57).
If a child restraint system is fitted to the front-
passenger seat and the 4PASSENGER
AIRBAG OFF indicator lamp does not light up
on the centre console:
R a child restraint system without transpond-
ers for automatic child seat recognition is
fitted or
R a child restraint system with transponders
is not properly fitted.

Important safety notes G
WARNING
A seat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, cannot provide the intended
level of protection. Under certain circumstan-
ces, this could cause severe or even fatal inju-
ries in the event of an accident.
Therefore, make sure that all occupants —in
particular, pregnan twomen —wear their seat
belts correctly at all times.
R The seat belt must fit snugly on your body
and must not be twisted.Therefore, avoid
wearing bulky clothing, e.g. a winter coat.
The shoulder section of the belt must be
routed across the centre of your shoulder
—onn o account across your neck or under
your arm —and pulled tight against your
uppe rbody. The lap belt must always pass
across your lap as low down as possible, i.e.
over your hip joints —not across your abdo-
men. If necessary, push the seat belt
slightly downwards and adjust it by pulling
it in the direction the seat belt retracts.
R Do not route the seat belt strap over sharp
or fragile objects. Please make sure that
such objects are not on or in your clothing,
e.g. spectacles, pens or keys etc. The seat
belt strap could become damaged and tear
during 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 another occupant. The
child will not be secured in the event of an
accident, heavy braking or sudden change
of direction .This may result in the child or other occupants being seriously or fatally
injured.
R Persons under 1.50 mtall cannot wear the
seat belts correctly. For this reason secure
persons less than 1.50 m tall in specially
designed, suitable restraint systems.
R Children unde r1.50 mtall and younger
than twelve years of age canno twear the
seat belts correctly. For this reason secure
them in special suitable child restraint sys-
tems installed on a suitable seat. Additional
information can be found in the Operating
Instructions in the chapter "Safety", "Chil-
dren in the Vehicle". Observe the installa-
tion instructions of the child restraint sys-
tem manufacturer.
R Do not secure an object with a seat belt if
the seat belt is also being used by one of
the vehicle's occupants. G
WARNING
The seat belt does not offer the intended level
of protection unless the backrest is almost
vertical. Under certain circumstances, this
could cause severe or even fatal injuries in the
event of an accident.
Before starting a journey, make sure that the
seat is properly adjusted and that the back-
rest is almost vertical. G
WARNING
Ad irty or damaged seat belt or one that has
been modified or subjected to a load in an
accident no longer offers the intended level of
protection. Under certain circumstances, this
could cause severe or even fatal injuries in the
event of an accident.
For this reason, chec kregularly that the seat
belts are not damaged or dirty.
Always have damaged seat belts or seat belts
that have been subjected to a load in an acci-
dent replaced at a qualified specialist work-
shop.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat belts which have Occupant safety
