It may be due to failure of the handbrake ratchet mechanism. Here is an introduction to automotive handbrakes: 1. Overview: The parking brake, commonly known as the handbrake, functions to provide resistance when parking, preventing the vehicle from rolling. The parking brake, whether manual or the parking gear in automatic transmissions, locks either the driveshaft or rear wheels. The parking brake exerts significantly less force compared to the service brake, just enough to prevent rolling on slopes. 2. System: The electronic parking brake system integrates temporary braking during driving with long-term parking braking functions, achieving parking brake control through electronic means.

Does 'on' represent normally open or normally closed?

on represents normally open. After pressing the 'on' button, the function is in the working state. The corresponding 'off' button is the shutdown button. After pressing the 'off' button, the function is in the off state. Functional buttons on cars are divided into: 1. 'mute' is the mute button, used to control the mute mode of multimedia; 2. 'mode' is the mode button, used to switch multimedia modes; 3. 'gps' is the locator, used for vehicle positioning tracking, driving trajectory playback, electronic fencing, and fuel monitoring; 4. 'set' with an exclamation mark is the tire pressure monitoring button, which will alarm immediately when the tire pressure is insufficient; 5. 'sync' is the dual-zone air conditioning adjustment. The red light indicates synchronized temperature adjustment, and turning it off means adjusting the air conditioning temperature on both sides separately.
