If the car drives normally, book a garage and show them this code: its exact meaning and the cause depend on each model.
Tell us what you notice: the diagnosis takes the code, your car and the symptoms into account.

Engine / equipment
Hybrid battery cooled with cabin air (intake next to the rear seat): Prius, Yaris, Auris, Corolla, C-HR, RAV4, Camry and others
Period mentioned
2003 onwards
Symptoms
Hybrid battery cooling maintenance message, warning light with codes P0A80 or P0A7F, a noisy fan and less electric assistance; if ignored, the battery ages faster.
Possible cause described
Dust, pet hair or dirt block the filter and fan that cool the battery; so do objects covering the intake. Toyota USA issued bulletin T-SB-0074-20 (2003–2020 Prius and Camry, Corolla, Highlander, RAV4 and Mirai hybrids up to 2020) and recommends cleaning the filter every 5,000 miles (about 8,000 km).
Check for the garage
Clean or replace the filter and clean the fan before condemning the battery; keep the intake grille clear. At the garage, read the codes and, if needed, install the software Toyota specifies.
