To reset the service light on a 2010 Holden Cruze, turn the ignition key to the "ON" position without starting the engine. Press the accelerator pedal three times within five seconds. Afterward, turn the ignition off, then back to the "ON" position to confirm the service light has been reset. If it remains on, you may need to repeat the process.
That REQUIRES an ENGINE SCANNER to do that.
