Airbag system
There is a fault in the system if the control
lamp :
●
does not light up when the ignition is
switched on ›››page46,
●
turns o after 4 seconds after the ignition is
switched on,
●
turns o and then lights up again after the
ignition is switched on,
●
illuminates or ashes while the vehicle is
moving.
The airbag system is not triggered if:
●
the ignition is switched o
●
there is a minor frontal collision
●
there is a minor side collision
●
there is a rear-end collision
●
in the event of the vehicle overturning if the
dynamic characteristics measured by the con-
trol unit are too low,
●
the impact speed is lower than the reference
value programmed in the control unit.
WARNING
●
The seat belts and airbags can only provide
maximum protection if the occupants are
seated correctly ›››page34.
●
If a fault has occurred in the airbag sys-
tem, have the system checked immediately
by a specialised workshop. Otherwise there is
a danger that during a collision, the system
may fail to trigger, or not trigger correctly.
Airbag activation
The airbags deploy extremely rapidly, within
thousands of a second, to provide additional
protection in the event of an accident. A ne
dust may develop when the airbag deploys.
This is normal and it is not an indication of re
in the vehicle.
The airbag system is only ready to function
when the ignition is on.
In special accidents instances, several airbags
may activate at the same time.
In the event of minor head-on and side col-
lisions, rear-end collisions, overturning or roll-
over of the vehicle, airbags do not activate.
Activation factors
The conditions that lead 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 predened
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 serious
head-on collisions:
●
Driver airbag.
●
Front passenger front airbag
●
Knee airbag for the driver.
The following airbags are triggered in serious
side-on collisions:
●
Curtain (head) airbag on the side of the acci-
dent.
●
Front side airbag on the side of the accident.
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;
