What Causes the Auto Hold Function to Be Restricted?
1 Answers
There are two main reasons why the auto hold function may be restricted: first, a brake function failure that prevents automatic braking, requiring manual intervention to brake. Second, a malfunction in the vehicle's auto hold system sensors. The solution is to turn on the ignition key, press and hold the foot brake, then push down the electronic parking brake for 5 seconds, followed by pulling it up for another 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 enabled, it provides better driving safety for the owner. At traffic lights, the auto hold function simplifies the driver's operations. Once activated, it eliminates the need to manually engage the parking brake. For automatic transmission vehicles, it avoids the need to repeatedly switch between D (Drive) and N (Neutral) 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 must be manually activated—their control methods differ. Enabling auto hold after starting the vehicle provides better safety assurance while driving. Engine start-stop technology requires specific conditions to activate, typically engaging after the brake is fully pressed for two seconds. In contrast, auto hold activates immediately upon fully pressing the brake. When both functions are active, releasing the brake will engage the auto hold.
