WARNING
on the instrument
The seat belts and airbags can only pro-
●
vide maximum protection if the occupants
are seated correctly
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 fine
dust may develop when the airbag deploys.
This is normal and it is not an indication of fire
in the vehicle.
The airbag system is only ready to function
when the ignition is on.
In special accidents instances, several air-
bags may activate at the same time.
In the event of minor head-on and side colli-
sions, 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 gener-
Safety
alised. Some factors play an important role,
such as the properties of the object the vehi-
cle hits (hard/soft), angle of impact, vehicle
speed, etc.

Deceleration trajectory is key for airbag acti-
vation.
The control unit analyses the collision trajec-
tory and activates the respective restraint
system.
If the deceleration rate is below the prede-
fined reference value in the control unit the
airbags will not be triggered, even though the
accident may cause extensive damage to the
car.

ous head-on collisions:
