See the link below for a definition of dash warning lights. - TechJK ------------------------------------------
The meaning of a dashboard warning light on an Oldsmobile Intrigue could be a variety of things. There are different lights for different things for different years of that model. It could be a service engine, check oil, sensor check, or more. The owners manual should have a listing of warning lights included in it.
The check engine and other dash warning lights can be reset by disconnecting the vehicles battery for more then 5 minutes. If warning light continues after reconnecting battery then there is still a problem.

By "OFF," I have to assume that your question means that the ignition switch is "ON", but the engine is not running. IF that is what your question means, then the reason the engine warning lights turning on is that the manufacturer designed the system that way to show you that those warning circuits and lights are working, and ready to warn you after you start the engine, should there be a failure in one of the systems they represent.
