If you have noticed that your auto hold light is on, it’s important to understand why this may be the case. Auto hold functions as a parking brake by preventing your vehicle from rolling when it is stationary. When the auto hold light comes on, it indicates that there is an issue with the system which needs to be addressed before further driving can take place. Possible causes for why your auto hold light might come on include low brake fluid levels or a faulty pressure sensor in the braking system. Additionally, if you recently replaced any parts of the braking system such as rotors or pads, these could also be causing issues with your auto hold function working correctly. It’s always recommended that you consult with a qualified mechanic if you are unsure about what has caused your auto-hold light to turn on so they can properly diagnose and repair it for you.
