How to turn off the Hill Descent Assist light on the Highlander?
3 Answers
Enter the main driver's cabin of the car, and you will see a button in front of the gear shift. There are two different buttons for the Hill Descent Assist system on the car. Press it once when going downhill, and it will light up. Press it again to turn it off.
Last time I took my Highlander out camping, the downhill assist light suddenly came on. At first, I was a bit panicked, but then I realized the light was on because the system was working. To turn it off, it's very simple—just look for a small button on the center console labeled DAC or Downhill Assist, press it once, and the light will go off. If the light stays on and won't turn off, it might be a minor system issue, like a dirty sensor or an electrical problem. I recommend wiping around the button with a soft cloth. In normal driving, downhill assist is quite useful—it helps automatically control your speed to prevent skidding. But if you find it annoying, like when the light stays on unnecessarily on flat roads, turning it off poses no risk. I usually only turn it on when needed, which also saves a bit of fuel.
The Hill Descent Assist light on the Highlander, I encounter it a few times during my daily commute. When the light is on, it means the system is active. You can press that round button near the steering wheel once to turn off the light. But don't turn it off casually, especially on steep slopes, as it prevents rollback accidents. If the light won't turn off, it's likely a button contact issue or system malfunction—check for dust blockage or try waiting for the system to complete its self-check after starting the car. I installed a mobile app to monitor the system status, but it's best to follow the manual's instructions.
