Just bought it some questions - please

What is the little key that is not really a key for?
Why would my change oil light come on every time i start the engine then shut off after a couple of minutes?
There is a panel up on the roof console that states with a red indicator that the tail lights is indicating something? What is this indicating and why if all the lights are working?

What little key resembling object are you refering to? I've got the master key that'll only fit in the ignition, and the other key is used for unlocking the doors, trunk and glove box. The oil light is coming on because it probably wasn't reset after the oil was changed. Assuming the oil is new and doesn't need changing, you can reset the lamp by pressing a pencil tip (eraser side) into the small hole underneath the dash inside the sound insulator on the passenger side. When doing this, make sure the ignition is set "on". Hold the button in with the pencil for about five seconds, and you should see the "Change oil soon" light flash a few times, then go out. That'll take care of that. As for the lamp monitor, I suggest double checking your license plate, rear corner, reverse and 3rd brake lights..these are obviously harder to detect! Good luck

on the 93-96 PA's, the oil reset switch is in the glovebox. 01-92 is where loekee said it was.

Lamp monitors are notorious for showing lights out when they are actually perfectly fine. Just check the lights to make sure theyre fine and ignore the monitors :)
