Impact detection zones

A. Front impact zone.
B. Side impact zone.
Triggering of the airbag(s) is accompanied by a slight emission of harmless smoke and a noise, due to the activation of the pyrotechnic cartridge incorporated in the system.
This smoke is not harmful, but sensitive individuals may experience slight irritation.
The noise of the detonation may result in a slight loss of hearing for a short time.
