deployment.
The vehicle may be deformed significantly,
e.g. the bonnet or the wing, withou tanairbag
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 sufficien tdeceleration
occu rsas aresult.
i The fron tbelt tensioners can only be trig-
gered if the seat belt tongues on the front
seats are cor rectly engage dinthe seat belt
buckles.
i Not all airbags ar edeployed in an acci-
dent .The different airbag system swork
independently of each other.
How the airbag system work sisdeter-
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 ,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 posi tioned
as close to th evertical as possible. The head restraint must support th
eback of the
head at about eye level.
R always secur echildren less than
1.50 mtall or under 12 years of age in suit-
able 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
the centre of the driver' sairbag cover as
possible.
R move the front-passenger seat as far back
as possible .This is especially important if
you hav esecured achild in achild rest raint
system on the front-passenger seat.
R vehicle occupant s–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 atrans-
ponde rfor automatic child seat recogni-
tion ,children must be secured in achild
rest raint system on asuitable seat in the
rear. If you secure aforward-facing child
rest raint 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. 42

Important safety notes G
WARNING
To reduce the risk of serious or even fatal
injury to the child in the event of asudden
change in direction, braking or an accident:
R children less than 1.50 mtall and under
twelve years of age must always be secured
in special child restraint systems on asuit-
able vehicle seat. This is necessary
because the seat belts are not designed for
children.
R Do not drive with achild secured in arear-
ward-facing child restraint system on the
front-passenger seat. Exception: if the vehi-
cle is equipped with automatic child seat
recognition on the front-passenger seat
and the child is secured in achild restraint
system with transponders for automatic
chil dseat recognition
R if you secur eaforward-facing child
restraint system to the front-passenger
seat, you must mov ethe front-passenger
seat as fa rback as possible.
R children must never travel sitting on the lap
of another occupant. Due to the forces
which occur in the event of asudden
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. 50
