“Oil Change” with a flexible setting *1 is available. Consult your Authorized Mazda Dealer when you want to change the setting *2 . Once the system turns on, the wrench indicator light in the instrument cluster will be illuminated when remaining oil life becomes less than 500 km (300 mile), or remaining days are less than 15 (whichever comes first).
Reset method
Press and hold the selector with the ignition switched off, then switch it on. Keep pressing the selector for more than 5 seconds. The master warning light will flash for a few seconds when the reset is completed.

*1 The flexible setting is available in the United States and Puerto Rico. Based on the engine operating conditions, the onboard computer in your vehicle calculates the remaining oil life. Mazda Genuine 0W-20 oil and Castrol ® 0W-20 oil are required to achieve optimum calculation performance.
*2 Once the Flexible Oil Maintenance Setting is selected, the system must be reset whenever replacing the engine oil.
