Anche leggendo il manuale d'officina che ho qui davanti dice:
RESET SERVICE WARNING LIGHT
At vehicle ignition, immediately after the ignition
check, if there are less than 187.5 miles (300 km)
to the next scheduled service, the corresponding
icon flashes for 5 seconds. Once the service mile-
age has been reached, the icon remains steadily
on until it is reset.
The resetting of the service is done by holding
down the MODE key to the key connection for
more than 10 seconds. For the first 5 seconds, the
instrument panel will not give any signal, for the
next 5 seconds the key icon will blink at a frequen-
cy of 1Hz. If the button is released before the 10
seconds, the service is not reset.
