AIRBAG SYSTEM
Airbaa System
2. SIDE AIRBAGS
The side airbags provide the driver and front passenger with a restraint supplementary to that by
the seat belts in the event of a side-on collision. When an impact greater than the set level is applied
to either side of the vehicle, the relevant side airbag sensor sends an ignition signal to the corre-
sponding airbag control module. The side airbag module operates to inflate the airbag, thus re-
ducing the shock inflicted in the outside upper body (chest) of the driver or front passenger.
