When service coupon threshold is achieved, upon every key-on the system displays the indication of the type of intervention that is required (oil service or desmo service).
The (red) warning is activated as a large icon for 10 seconds upon every key-on (1) then as a small warning that remains displayed (2) until it is reset.
After reset, the system will display again the type of intervention required next and the residual range (as described in the previous paragraph).
