The Mazda CX-30 Mk1 (DM) 2019-Present is a compact crossover slotting between the CX-3 and CX-5, offered with Skyactiv-G petrol and the Skyactiv-X compression-ignition engine. After it has been serviced this generation typically needs the oil service light reset so the maintenance counter restarts, along with a service reminder reset via the instrument cluster menu. A TPMS reset keeps the tyre-pressure warning accurate after seasonal swaps, a brake pad wear reset follows new pads, and the powered windows may need reinitialising after a 12V battery reset. Button sequences shifted slightly across model-year updates, so verify your car. Select the reset procedure you need from the list below to follow the correct method for your CX-30.
