The detected diagnostic errors can be deleted from the memory of the control unit simply by pres-
sing the key on the bottom right “Errors resetting”.
The detected error will be signaled to the driver by the switching-on with fi xed light of the YELLOW
LED and the slow blinking of the green LED on the switch. Moreover, to ease the identifi cation of
the alarm status, it is enabled the buzzer present within the switch itself.
To disable the acoustic alarm, press the push-button of the switch switching the car feeding from
gas to petrol.
To return to GAS operation, it is necessary to shut-off and re-start the vehicle.
In the case of diagnosis “Gas temperature too cold” (S111) the display is different: the switchover
indicates the switch to gasoline, but the system is ready to re-switch to gas as soon as the condi-
tions for switching to gas are restored.
