How to turn on the TRC in 2023 Toyota Harrier?
To prevent additional downshifting and wheelspin, the TRAC system activates and deactivates the traction control. Hold the button briefly to disable the TRAC system, triggering the illumination of the TRAC OFF indicator. To re-enable the system, press the switch once more. However, to be safe, please contact Toyota's service center for any maintenance needs.
