BMW 325i E36

Good, the first thing to thank you for welcoming me on your page and your forum, I tell you, eh acquired a 325i e36 I have no manual and its former owner does not have it or know how to answer my doubt, because when I turn the key in the contact in the display where I mark the km later the km appear some yellow and red green paintings, I want to know what they mean and now even more I do not turn on one of the green Passing the user manual would be great, thanks and greeting to all
