Airbag system
Activation factors
The conditions that l
ead to the airbag system
activating in each situation cannot be general-
ised. Some factors play an important role, such
as the properties of the object the vehicle hits
(hard/soft), angle of impact, vehicle speed, etc.
Deceleration trajectory is key for airbag activa-
tion.
The control unit analyses the collision trajec-
tory and activates the respective restraint sys-
tem.
If the deceleration rate is below the predefined
reference value in the control unit the airbags
will not be triggered, even though the accident
may cause extensive damage to the car.
The following airbags are triggered in seri-
ous head-on collisions:
●
Driver airbag.
●
Front passenger front airbag
●
Knee airbag for the driver.
●
Head airbags.
In the event of serious side collisions, some
(or all) of the following airbags can be acti-
vated (depending on the severity of the col-
lision):
●
Curtain (head) airbag on the side of the acci-
dent.
●
Front side airbag on the side of the accident.
●
Rear side airbag on the side of the accident.
●
Central airbag.
In an accident with airbag activation:
●
the interior lights switch on (if the interior light
switch is in the courtesy light position);
●
the hazard warning lights switch on;
●
all doors are unlocked;
●
the fuel supply to the engine is cut;
●
in hybrid vehicles, the high voltage system is
switched o;
●
an emergency call is started.
Airbag system control lamps
Lights up on the instrument cluster
F
ault in the airbag system and seat belt
tensioners. Have the system checked im-
mediately by a specialised workshop.
Lights up on the roof console
Front passenger front airbag deactivated.
Check if the airbag should be kept deacti-
vated.
Lights up on the roof console
Front passenger front airbag activated. The
control lamp turns o automatically 60
seconds after the ignition is switched on.
Several warning and control lamps light up for
a f
ew seconds when the ignition is switched
on, signalling that the function is being verified.
They will switch o after a few seconds.
If the airbag and seat belt tensioner system
control lamp
remains on or flashes, it indi-
cat
es a malfunction in the airbag and seat
belt tensioner system ›››
. Have the system
check
ed immediately by a specialised work-
shop.
If the front passenger airbag has been deacti-
vated, the warning lamp
remains lit on the
r
oof console to remind you that the airbag is
deactivated. If, with the front passenger airbag
deactivated, this lamp does not remain lit or
if it is lit along with the control lamp
on the
instrument panel, ther
e is a fault in the airbag
system ›››
. If the control lamp is flashing,
ther
e is a fault in the disabling of the airbag
system ›››
. Have the system checked imme-
diat
ely by a specialised workshop.
WARNING
In the event of a fault in the airbag and seat
belt t
ensioner system, the airbags and seat
belts may not trigger correctly, may fail to
trigger or may even trigger unexpectedly.
