I get this flashing symbol when I start my car then it reverts to mileage.
any idea what it is

 

The "double wrench" means you need service (check the manual) and the -20 means you're 20 miles past the service time; a double wrench means a more significant service interval (Schedule B) is due.

Thanks for posting the question. I have wondered the same thing for a while but had not gotten around to asking about it.

 

All of this information is in your vehicle's owner's manual.
If you don't have one you can download it under the "TBS-and How Tos" section of the forum.
