Standby Power Supply, Air Bag

The air bag system provides an auxiliary power supply, sufficient to deploy the frontal air bags for a minimum of 150 mS in the event of failure in the vehicle power supply. The back-up power supply is discharged within 60 seconds after disconnecting the battery positive terminal or battery ground cable. This makes sure that the frontal air bag system remains operative.
