Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.
i Please read the information on qualified
specialist workshops (Y page 25).Occupant safety
Important safety notes
The seat belts, together wit hSRS (Supple-
mental Restrain tSystem), are complemen-
tary, co-ordinated restrain tsystems
(Y page 43). They reduce the ris kofinjury
in specific, pre-defined types of accident sit-
uations and thereby increase occupant
safety .However, seat belts and airbags gen-
erally do not protec tagainst objects pene-
trating the vehicle from the outside.
To ensure that the restraint systems can
deliver their full potential protection, make
sure that:
R the seat and head restraint are adjusted
properly (Y page 104).
R the seat belt has been fastened properly
(Y page 51).
R the airbags can inflate unrestricted if
deployed (Y page 44).
R the steering wheel is adjusted properly
(Y page 104).
R the restraint systems have not been modi-
fied.
i An airbag increases the protection of
vehicle occupants wearing a seat belt.
However, airbags are only an additional
restraint system which complements, but
does not replace, the seat belt. All vehicle occupants must wear their seat belt cor-
rectly at all times, even if the vehicle is
equipped with airbags. The airbags are not
deployed in all types of accidents. For
example, if the protective capacity of cor-
rectly fastened seat belts is not increased
by deploying the airbags, the airbags will
not deploy. Airbag deployment only pro-
vides increased protection if the seat belt
is worn correctly because:
R
the seat belt helps to keep the vehicle
occupant in the best position in relation
to the airbag.
R in a head-on collision, for example, the
seat belt prevents the vehicle occupant
from being propelled towards the point
of impact. It can 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. G
WARNING
Modifications to or work performed incor-
rectly on the following parts can result in the
restraint systems not functioning as intended:
R the restraint system, consisting of seat
belts and their anchorage points, belt ten-
sioners, belt force limiters and airbags
R the wiring
R networked electronic systems
Airbags and belt tensioners could fail to
deploy or be triggered in an accident despite
the deceleration force being sufficient to trig-
ger the systems, or could be triggered unin- 42
Occupant safetySafety
tentionally. For this reason, never make any
modifications to the restraint systems.
Therefore, you must not tampe rwith elec-
tronic components or their software. SRS (Supplemental Restraint System)
Introduction 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 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 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
WARNING
If SRS is malfunctioning, individual systems
may be triggered unintentionally or might 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.
Triggering of belt tensioners, belt force
limiters and airbags During the firs
tstage of a collision, the airbag
control uni tevaluates important physical
data relating to vehicle deceleratio noraccel-
eration, such as:
R duration
R direction
R magnitude
Based on the evaluation of this data, the air-
bag control uni tpre-emptively triggers the
beltt ensioners in the first stage.
i The fron tbelt 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 fron tairbags 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 exceeded 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.
i Airbags are not deployed in all types of
accidents. Also, not all airbags are
deployed together in an accident. The dif-
ferent airbag systems work independently
of each other. Occupant safety
43Safety Z
How the airbag system works is deter-
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 rate of vehicle deceleration or accelera-
tion and the directio nofthe 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. 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
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.
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 44
