If the car only has 9000km then something is not right.
Maybe I have it backwards (I don't have my manual in front of me) and maybe the -425 means you have 425km before service and it would count down. Maybe another forum member who has their manual handy could chime in.

I believe the A service is basically an oil change. We can normally go 7,000 to 7,500 miles between oil changes but it depends on how you drive. It is possible that at 5,592 miles you are 380km away from service.
