Service Interval Indicator (SIA)
The Service Interval Indicator up to 96 models uses the SIA II processing as in the past models. The models from 96 uses the SIA III processing which uses the miles traveled and the "ti" signal to calculate service intervals. The reset of Service Indicator is carried out with the reset tool on early models up to 9/00. Later models (from 9/00) are reset through the instrument cluster test functions (reset mode).
Trip Odometer Reset
The left button on the cluster is used to reset the trip mileage if the key is on and display mileage if the key is off.
