Mine came on for the first time the other day, it came on when i was at the bottom of the red, drove to the petrol station about 5 miles away and it didnt run out.. im sure i read in the manual it has 10 litres left in the tank i wouldnt really want to try it though.
My screen wash light comes on when i flick the ignition.. but doesnt falsh. Does the same in my dads car aswell, but thats an xr so could be different.
