Video tutorial

The car's control unit also includes a sensor that automatically detects when it's time to change the engine oil. However, it can often happen that there is an error in data detection, and a warning light appears on your onboard computer. To reset this light and allow the control unit to re-read the data, it only takes a few seconds.

Keep the car's engine off and turn on the ignition only. Locate the hazard light button, positioned just below the radio.

Scroll to the right and notice a button located between a "minus" and a "plus". Press and hold it for about thirty seconds, and you're done.
