What does it mean when the auto hold function is restricted?

[Zoey]

"Auto hold function restricted refers to a brake function failure where automatic braking is not possible, requiring manual operation to achieve braking. This is typically caused by a sensor malfunction in the vehicle's auto hold system. The solution is to turn on the car key, press and hold the foot brake, then press down the electronic parking brake for 5 seconds, followed by pulling up the electronic parking brake for 5 seconds. This will reset the electronic auto hold. Related details are as follows: Auto hold is an automatic braking function: When the auto hold function is activated, it provides better driving safety for the owner. At traffic lights, the auto hold function simplifies the driver's operation steps. Once activated, it eliminates the need to pull the handbrake. For automatic transmission vehicles, it avoids the need to repeatedly switch between D and N gears, making it convenient to use and enhancing driving safety. Difference between engine start-stop and auto hold: Engine start-stop is a default-enabled function, while auto hold requires manual activation, meaning their control methods differ. Activating the auto hold function after entering the car provides better safety during driving. Engine start-stop technology requires specific conditions to activate, usually starting after holding the brake for two seconds. However, the auto hold function activates immediately upon pressing the brake firmly. When both are in operation, releasing the brake will cause the auto hold to take effect."
