On the driver's side is a gas generator and airbag. The gas generator is fitted in a plastic housing. The airbag is protected by a plastic casing with fracture lines fitted to the metal bracket. The airbag has a volume of 60 litres.
The steering wheel centre pad (airbag module) is supplied with test and detonation current from a coil spring (contact roller), which also supplies the SID with information from the steering wheel buttons.

The gas generator comprises a light-alloy housing, electric detonator, explosive charge and filter. The gas generator is detonated in two stages: a primary stage (70%) and secondary stage (30%). The delay between the two detonations depends on the information the control module receives from the various sensors.
On receiving an activation command, the control module sends a current pulse to the detonator which ignites the explosive charge. On combustion, this explosive charge generates a gas. The filter cools the gas and removes particles from it before it passes into the airbag.
For more information on detonation signals, see Airbag control module .
