Caution / Notice / Hint
WARNING: This page is about a different car, the 2022 Toyota Corolla, 2021 Toyota Corolla, and 2020 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
HINT:
Even if the accelerator pedal position is maintained, the hybrid system output may increase when driving uphill and decrease when driving downhill. This is due to drive start control controlling the hybrid system output, and is not a malfunction.
