Strange that I've never seen that maintenance required message. I've had the car from 69000kms to its current 92000km.

There is a Maintenance section in the settings on the touchscreen. I disabled all the maintenance settings there. If you have the nav touchscreen package and can keep track of your mileage/maintenance needs, give that a try.

 

That's cos you have pre-restyle car.... I think this message is for 03+ cars only...
