Video tutorial

On Mazda CX vehicles, you can reset the service light yourself directly from the onboard computer, without going to a repair shop. Get in the vehicle and ensure the display shows the odometer screen (the mileage counter), then turn off the car and press the button on the dashboard shown in the video.

While holding it down, turn the key and start the engine. Wait a few seconds (preferably a minute), turn off the car, and release the button.

The light is now reset, and you can verify it by turning on the instrument cluster.
