What is the function of automatically engaging the handbrake when shifting to P gear?
2 Answers
The function of automatically engaging the handbrake when shifting to P gear is designed as the parking gear. Function of the parking gear: After shifting to P gear, although the transmission is in the neutral position, the drive shaft is locked, and the drive wheels can no longer rotate. For front-wheel-drive vehicles, engaging the P gear and tightening the handbrake means all wheels are locked. Principle of the parking gear: P stands for Parking gear, used when parking (when turning off the engine or idling for a long time). The principle of using it during long-term parking is to lock the car using the internal mechanism of the transmission, so it must only be used when the car has come to a complete stop.
The moment I got into that new car, I noticed this feature—every time I shift into P, the electronic parking brake engages automatically, feeling like a thoughtful assistant watching over safety. Turns out, this is Hyundai's advanced electronic parking system, computer-controlled where the gearshift senses the P position and triggers a signal to the parking brake module, automatically locking the wheels. Combined with auto hold, it’s incredibly convenient—no more manual lever-pulling when parking, especially on slopes where rollback accidents are a concern. Some models even release it automatically upon starting, simplifying operations further. However, be cautious: if the battery is low or the system malfunctions, the parking brake may fail, so regular maintenance of electrical circuits is crucial—avoid unauthorized modifications or messy wiring that could shorten its lifespan. This feature makes driving safer and more efficient, but it’s best to familiarize yourself with the manual to handle emergencies if a fault occurs.
