Vehicle Engine Control Unit Reset Procedure
This following procedure is for SKYACTIV-G 2.5T vehicles, and for SKYACTIV-G 2.5 vehicles with the engine oil flexible maintenance setting is selected.

If the value recorded by the computer is not initialized, the wrench indicator light may not turn off or it may turn on earlier than normal.

-
Switch the ignition OFF.
-
Switch the ignition ON with the dashboard illumination knob pressed, and press and hold the dashboard illumination knob for about 5 seconds until the master warning light
flashes.
-
After the master warning light
flashes for several seconds, the initialization is completed.
