A maintenance light will appear on the instrument panel when an oil change is due for the Mazda 6. You can reset the maintenance light with these steps.
- Switch the ignition completely off.
- Press and hold the stem button on the upper-right side of the instrument panel.
- Continue to hold the stem while switching the ignition to the ON position. Do not start the engine.
- Still holding the stem, wait about 5 seconds until the master warning light flashes. Once this happens, the maintenance light has been reset.
You may have to try these steps a few times before it actually works. I hope this guide has helped you. Leave me a comment below.
