Service Interval Indicator

Service Interval Indicator

The Service Interval Indicator (SIA) is displayed in the message center. The SIA displays information calculated by the instrument cluster to calculate the remaining distance to the next service based on the amount of fuel used since the last SIA reset. It can also calculate the remaining time until the next service is required.

For the fuel based remaining distance, the message center displays 'OILSERVICE 1000MLS (KMS)'. The SIA will not display more than 1000 miles or kilometers and will count down, with a reduction in distance remaining as the vehicle is used. A vehicle which is driven aggresively will require a service more often than a vehicle which is driven economically.

For the time based period to next service, the message center displays 'INSPECTION 05.2005'. The instrument cluster calculates the remaining time between services based on the last SIA reset. If the vehicle has not used enough fuel to display the fuel based oil service, the time based inspection service will be displayed.

NOTE: Japan and NAS markets do not have the time based SIA display. SIA is calculated only on the fuel consumption in these markets.

The service information is displayed for 5 seconds at each ignition on cycle. A minus sign is displayed alongside the SIA information if the distance or time has been exceeded and the distance or time by which it has been exceeded.

The SIA information is stored in the instrument cluster EEPROM and can only be reset using T4.
