Can the Electronic Parking Brake Be Used After the Engine Is Off?
2 Answers
Electronic parking brake can be used after the engine is off. The electronic parking brake is a technology that uses electronic control to achieve parking braking. Its working principle is the same as that of a mechanical handbrake, both of which achieve parking braking control through the friction generated between the brake disc and the brake pads. The only difference is that the control method has changed from the previous mechanical handbrake lever to an electronic button. The electronic parking brake, also known as the electronic parking brake system, integrates the temporary braking function during driving with the long-term braking function after parking, and uses electronic control to achieve parking braking. Its advantages include saving the space occupied by the mechanical handbrake and creating a larger central control space.
I tried this before when using a new car. The electronic parking brake still works after turning off the engine—just press the button to activate it. That time, I parked on a slope and turned off the engine. Worried about rolling, I pulled the electronic parking brake, the dashboard light came on, and the car stopped firmly. It felt quite convenient, but you need to watch the battery level. If the engine is off for a long time or the battery is nearly dead, it might fail. So, I regularly check the battery status and measure the voltage every six months. Also, when parking on slippery roads, it's best to engage the electronic parking brake before turning off the engine to avoid unexpected movement. As for related advice, avoid repeatedly operating it after turning off the engine since it relies on the 12V battery—frequent use can accelerate battery aging. I usually have no issues using it after parking and turning off the engine in the city, but caution is needed in remote areas or during long stops. In short, it works, but it’s not entirely worry-free—developing good habits is safer.
