I recently purchased an XJ6, which did not come with an owner's manual. I am now getting a symbol on the instrumentation panel, left side verticle strip of indicators. It is a circle with a rectangular shape at the top, and an X through the circle. I have no idea what this is supposed to represent. I've checked all the fluid levels, and topped off as necessary, although nothing seemed to be particularly low.

Can someone tell me what this symbol represents?

Also, any leads on where I can get an owner's manual for my car would be appreciated. I've seen one on E-Bay, but $100 seems to be a bit pricey.

Thank you.
