Understanding/Resetting dash indicators

Good afternoon. I've recently purchased a 1996 318ti. But it is without an owner's manual. Therefore, I've been unable to reset/adjust a couple of dash indicators without the procedures outlined. Best place to buy an owner's manual for that year/make/model? and, in the meantime, can anyone tell me how to reset the colored "oil change" grid just below the odometer?

If you pm me your email address, I could try to send you the service light reset instructions. I think I have them in MS Word format.
