Important safet
ynotes
Seat belts, together wit hthe Supp lemental
Restrain tSyste m–S RS (Y page 41), are
complementary, co-ordinated restrain tsys-
tems. They reduce the risk of injur yinspe-
cific, pre-defined types of accident situations
and thereby increase occupant safety .How-
ever ,seat belts and airbags generally do not
protec tagainst objec tspenetratin gthe vehi-
cle from the outside.
To ensur ethat the restraint system scan
deliver their full potential protection, make
sure that:
R the seat and head restraint are adjusted
properly (Y page 92).
R the seat belt has been fastened properly
(Y page 47).
R the airbags can inflate unrestricted if
deplo yed (Y page42).
R the steering whee lisadjusted properly
(Y page 92).
R the restraint systems have not been modi-
fied.
i An airba gincrease sthe protection of
vehicle occupants wearing aseat belt. As
such, they are only an additional restraint
system which complemen ts,b ut does not
replace, the seat belt. All vehicle occupants must wear their seat belt correctly at all
times, even if the vehicle is equipped with
airbags. The airbags are not deplo yed inall
types of accidents. For example, if the pro-
tective capacity of correctly fastened seat
belts is not increased by deplo yingthe air-
bags, the airbags will not deploy. Airbag
deploymen tonly provides incre asedpro-
tection if th eseatb eltisw ornc orrect ly
because:
R the sea tbelt helps to keep the vehicle
occupan tinthe best position in relation
to the airbag.
R in ah ead-on collision ,for example, the
seat belt prevents the vehicle occupant
from being propelled towards the point
of impact .Itcan thus reduce the risk of
injury.
In accidents in which an airbag is deployed,
it provides increased protection only if the
seat belt is worn correctly. G
WARNING
If service work is not carried out correctly, the
operating safety of your vehicle may be affec-
ted. This could cause you to lose control of
your vehicle and cause an accident. More-
over, the safety systems may no longer be
able to protect you or others as they are
designed to do.
Always have service work carried out at a
qualified specialist workshop. The workshop
must have the necessary specialist knowl-
edge and tools to carr yout the work required.
Mercedes-Ben zrecom mends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop. 40

of
ac ollision .Inthe first deploymen tstage,
the front airbag is filled with enoug hpropel-
lan tgas to reduce the risk of injuries. The
front airbag is fully deployed if asecond
deployment threshold is exceeded within a
few milliseconds.
The belt tensioner and airbag triggering
thresholds are variable and are adapted to the
rat eofd eceleration or acceleration of the
vehicle. This process is pre-emptive in nature.
The triggerin gprocess mus ttake place in
good time at the start of the collision.
i Airbags are not deployed in all types of
accidents. Also, not all airbags are
deployed together in an accident .The dif-
ferent airbag system swork independently
of each other.
How the airbag system work sisdeter-
mined by the severity of the collision 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 rat eofvehicle 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 acollision 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 ma ybedeformed 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 rat
eofdeceleration 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 part ssuch as longitudinal body
members are hit, and sufficient deceleration
occurs as aresult. Airbags
Important safety notes Airbag deployment slows down and restricts
the movemen
tofthe vehicle occupant.
If the airbags ar edeployed, you will hear a
bang and asmall amount of powder may also
be released. Only in rare cases will th ebang
affect your hearing. The powde rthat is
released generally does not constitute a
healt hhazard. The 6SRS warning lamp
lights up.
The airbag installation locations are identified
by the AIRBA Gsymbol. G
WARNING
Airbags provide additional protection; they
are not, however, asubstitute 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 secur echildren less than 1.50 mtall
and under 12 years of age in suitable child
restraint systems.
R all vehicle occupant smust select aseat
position that is as far away from the airbag
as possible. The driver' sseat position must
allow the vehicle to be driven safely .The
driver's chest should be as fa raway from 42
Occupant safetySafety

the centre of the driver's airba
gcover as
possible.
R move the fr ont-passenge rseatasf ar back
as possible. Thi sisespecially important if
yo uh aves ecure dac hild in achild restraint
syste mont he front-passenger seat.
R vehicle occupants –inparticular ,children
–m ust not lean 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 fit tedtot he front-passenger
seat unless the front-passenger airbag has
been disabled. On the front-passenger
seat, the front-passenger airbag is disabled
if ac hild rest raint system with atrans-
ponde rfor automatic child seat recognition
is fit tedtot he front-passenger seat in a
vehicle equipped with automatic chil dseat
recognition. The 4PASSENGE RAIRBAG
OF Findicator lamp must be continuously
lit.
If the front-passenger sea tofyour vehicle
does not have automatic child seat recog-
nition ,oryour rearward-facing child
rest raint system does not have automatic
child seat recognition, children must be
secured in achild rest raint 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 possi-
ble.
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 airbag, partic-
ularly when the vehicle is in motion.
R do not put your feet on the dashboard.
R only hold the steerin gwheel on the outside.
This allow sthe airbag to be fully deployed.
You coul dbeinjured if the airbag is
deploye dand you are holding the inside of
the steerin gwheel. R
do not lean on the doors from insid ethe
vehicle.
R make sur ethat ther eare no people ,ani-
mals or obje ctsb etween the vehicle occu-
pants and the area where the airbags are
deployed.
R do not place any objects between the seat
back rest and the door.
R do not hang any har dobjects, for example,
coat hangers, on the grab handles or coat
hooks.
R do not atta chaccessories, e.g. cup holders,
to the doors.
It is not possible to rule out arisk 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 steerin gwheel boss
R kneebag cover below the steerin gcolumn
R front-passenger airbag cover
R outer side of seat bolsters G

WARNING
When adjusting the seat, mak esure that
nobody can become trapped.
! Make sure that there are no objects in the
footwell or behind the seats when moving
the seat back. There is arisk that the seats
and/or the objects could be damaged.

WARNING
As eat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, can notp erform its intended
protectiv efunction. Under certain circum-
stances, this could cause severe or even fatal
injuries in the event of an accident.
Make sure that all occupant s–inparticular,
pregnan twome n–w ear their seat belt cor-
rectly at all times.
R The seat belt must fit snugly on your body
and must no tbetwisted. Therefore, avoid
wearing bulky clothing, e.g. awinter coat.
The shoulder belt section must be routed
across the centre of your shoulder –onno
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 join ts–n ot 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
edge sorfragil eobjects, 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 vehicl eoccupants could
be injured.
R Onl yone person should use each sea tbelt
at any one time. Children must never travel

R Do not secure any objects with aseat belt
if the seat belt is also being used by one of
the vehicle's occupants. G
WAR
NING
The seat belt doe snot offer the intended level
of protection unless the back rest is almost
ver tica l. Under certain circumstances, this
could cause severe or even fatal injuries in the
event of an accident.
Befor estarting ajourney, mak esure that the
seat is properly adjusted and that the back-
rest is almost vertical. G
WARNING
Ad irtyord amaged seat belt or aseat belt that
has been subjected to aload in an accident
or which has been modified no longer offers
the intended level of protection. Un dercertain
cir cumstances, this could caus esever eor
even fatal injuries in the even tofanaccident.
For thi sreason, check regularly that the seat
belts are not damaged or dirty.
