Change service interval


On vehicle with flexible service interval, the service intervals are calculated, in addition to driven distance and time, also using fuel consumption and oil temperature. This calculation gives a value of the oil's degradation in relation to thermal loading. On vehicles with diesel engines the oil's degradation is calculated based on engine rpm, engine load, driven distance, and oil temperature. This gives values for thermal loading and soot deposits. Oil degradation is the decisive factor for when the next service shall take place.

With this function it is possible to adapt service interval data to fixed oil change interval or flexible oil change interval by changing value for oil quality. Values that can be selected are shown below:

  6. Exit the function.

    • If the function fails, check the test conditions and repair any faults.

  7. Go to the "Service" menu in the vehicle's trip computer and check that the selected interval has been registered.

    • "Fixed interval" must indicate: "15,000 km" and "372 days".

    • "Flexible interval" shall indicate: "--- km" and "--- days".
