The CX-30 (from 2020) is a small crossover based on the Mazda3. It uses 2.0- and 2.5-liter Skyactiv-G engines and the 2.5-liter turbo, with i-Activ AWD.



The 2021 Mazda CX-30 belongs to the CX-30 generation, built for model years 2020–2026. Most procedures are shared with the other years of this generation, but engines, options and wiring changed from year to year, so the manual is made for the 2021 model year.
Check the model year on your VIN: on a 2021 vehicle the 10th character of the 17-digit VIN is “M”. Vehicles built for North America always carry the model year in that position; on some European or Australian vehicles it may be left unused, so in that case go by the registration papers or the build plate.
At about 5 years old, a 2021 vehicle is usually past its basic warranty. Typical jobs at this age are brakes, suspension parts, fluids, the 12V battery and diagnosing sensor faults with the factory wiring diagrams.
Same generation: 2020 Mazda CX-30.
