We cover the Mazda3 across the BK, BL, BM/BN and BP generations. Engines include 2.0- and 2.3-liter MZR units, the Mazdaspeed3 2.3 turbo, 2.0- and 2.5-liter Skyactiv-G and the 2.5-liter turbo, with Skyactiv transmissions and i-Activ AWD.



Your 2010 Mazda 3 is from the second-generation Mazda3 (BL), which covers model years 2010–2013. It is the first model year of this generation: the platform, wiring and many procedures changed compared with the previous model, so a manual for an earlier year will not match it.
Check the model year on your VIN: on a 2010 vehicle the 10th character of the 17-digit VIN is “A”. 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 16 years old, a 2010 vehicle is in the age range where wiring, rubber hoses, seals and corrosion repairs take most of the work, and where original factory information is hardest to find.
Same generation: 2011 Mazda 3, 2012 Mazda 3, 2013 Mazda 3.
