Caution / Notice / Hint
WARNING: This page is about a different car, the 2024 Lexus TX 500h. 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.
