A two stage-ignition air bag apparatus for a vehicle of the present invention includes an air bag, a first inflator ignited when a value according to collision severity has reached a first threshold value in order to inflate the air bag, and a second inflator ignited at earlier one of times when the value according to collision severity has substantially reached a second threshold value that is greater than the first threshold value and when a predetermined time has passed since the value according to collision severity reached the first threshold value in order to inflate the air bag. Also, a method of igniting the two stage-ignition air bag apparatus of the present invention includes the steps of igniting the first inflator when a value according to collision severity has reached a first threshold value, and igniting the second inflator at earlier one of times when the value according to collision severity has substantially reached a second threshold value that is greater than the first threshold value and when a predetermined time has passed since the value according to collision severity reached the first threshold value.
