Car is Buick regal LS 1997 3.8L non-supercharged
My oil warning light (see photo) stays on when ignition is on, BEFORE cranking the engine. All other bulbs go off at the same time.
Its not clear from manual whether this is normal behaviour?

Also from the manual it seems charging indicator (looks like battery on instrument panel) should stay on till the engine is cranked, but mine turns off very fast, even if engine not getting cranked.
Is this normal or could indicate an issue in charging system?
Please share how instrument panel behave in your buick.
Thank you!
