METHODS OF RESTRAINT IN ADDITION TO THE FRONT SEAT BELTS
Operation
This system is only operational when
the ignition is switched on.
In a severe frontal impact, the air bags
inflate rapidly, cushioning the impact
of the driver's head and chest against
the steering wheel and the front pas-
senger against the dashboard. The air
bags then deflate immediately so that
the passengers are not in any way hin-
dered from leaving the vehicle.

Special feature of the front air
bag
After a violent impact, it has two deploy-
ment volumes and integrates a ventila-
tion system:
– small volume air bag, this is the first
stage of operation;
– large volume air bag, the air bag
seams rip so that a larger volume of
gas is released into the bag (for the
most severe impacts).
