Are you sure it doesn't say "INFL REST" It may be the inflatable restraint (air bag) having problems. Sounds like low voltage and if you are having other power issues, I would have my battery and alternator checked. Good luck, hope it helps.
Oh, and this is the 2005-2010 STS forum, so you might get better help in the forum pertaining to your car (assuming its the '93 sts your profile indicates that you own)
(Look, I called him out before 550HP STS-V got to it.) j/k
