2) In the X5 there are two different types of instrument panels. One has a mileage countdown until service with numbers, and one just has a countdown using green, yellow and red bars. You only have one or the other.

Hope that answers your questions. Again, you should read the manual from cover to cover (as you should with any car), but if you have any other questions we're all here to help.
