Mercury 1996 Sable Manual page 33

Inflated passenger-side air bag
The air bag will inflate only once.
The system is designed to function
on a one-time-only basis. If the air
bag is inflated, THE AIR BAG WILL
NOT FUNCTION AGAIN AND
MUST BE REPLACED
IMMEDIATELY. If the air bag is not
replaced, the unrepaired area will
increase the risk of injury in a
collision.
To ensure that the air bag system will operate as
intended in a crash, the system is equipped with
a diagnostic module. The diagnostic module
monitors its own circuits, the air bag electrical
system, the air bag readiness light, the air bag
power, and the air bag inflators.
