The 2012 Toyota Prius runs the naturally aspirated 1.8L hybrid four, the 2ZR-FXE, driving through Toyota's hybrid transaxle, and it is that specific car this service and repair manual was written against: this model year, this driveline, this trim range. The values and sequences you work to are the ones Toyota published for the 2012 car, not figures carried across from an adjacent model year of the same nameplate.

Known issues on the 2012 Prius. Four recalls are on federal record for this model year. Two of them involve air bags: 16V487000 covers the side and window curtain shield air bag, where either portion of the inflator ejects into the passenger cabin, and 13V014000 covers the frontal air bag sensor and control module, where the front passenger seat occupant sensing system is out of calibration. A third, 13V123000, is a labeling recall, because an inaccurate label could lead to owners overloading their vehicles and tires. The fourth, 16V396000, covers the front seat assembly heater: if damaged, the copper strand heating element may short circuit, increasing the risk of a fire. Beyond the recalls, 535 owner complaints are on record for this vehicle, and 214 technical service bulletins have been issued for it.
Whether the job is a hybrid system fault, an occupant sensing check after front seat work, or a heated seat circuit that has stopped behaving, this keeps you on the factory procedure and the right figure for the 2012 Prius.
