[Chevelle-list] BMW Z3 question

[Dale]

Anyone own or know about a BMW Z3? I recently bought one and there's a button switch on the left side of the dash under the fuel gauge that I can't figure out its purpose. It's a *press it once* and it stays depressed, press it again and it pops back out. Any ideas as to its purpose? I don't have an owner's manual and a service manual I have doesn't mention it.
