What does rescu failer mean - 2000 Lincoln LS

As I recall that rescue failure light comes on if one of the air bags has a failure and or been deployed at one time. If you check the engine light on the dash and when you turn the key as if you wanted to start the car but just to the first notch/position. The engine light will probably flash. Count the flashes and that is the fault code. There is a way to reset that, I don't recall; however any Lincoln service dept. mechanic will tell you. You may have to go to the dealer to speak to the service advisor to ask. Don't let them make your car an in-patient!
