ing an inflator and airbag (Side airbag equipped model).

FRONT AIRBAG SYSTEM:
A frontal impact exceeding the set level causes the safety sensor, electric sensor and one or both
front sub sensors to input impact signals to the CPU. The CPU determines whether the airbags
should be inflated or not based on these signals.
0
SIDE AIRBAG SYSTEM:
Input of a side impact signal showing shock energy greater than the set level causes the airbag
on the corresponding side to inflate.
