Do I still need to pull the handbrake after the auto hold turns off when the engine is off?

If you turn off the engine first and then unfasten the seat belt, you need to pull the handbrake button. If you unfasten the seat belt without turning off the engine, the auto hold button will automatically switch to handbrake mode, and you don't need to pull the handbrake again at this time. It is recommended to adopt the first mode. The following is a related introduction to auto hold: 1. Function: The English name of auto hold is AUTOHOLD. The function of auto hold is that the vehicle itself can automatically apply the brakes according to the actual situation without the driver's operation. 2. Working principle: The brake management system controls the braking of all four wheels through the extended function of the electronic parking brake (EPB). In other words, the auto hold system is an extended function of the electronic parking brake (EPB) and is controlled by the ESP component. When the vehicle is temporarily parked and needs to be restarted within a short period of time, the parking is completed by the brake controlled by ESP.
I strongly recommend applying the handbrake after the auto-hold function engages when the engine is off. The auto-hold system relies on electronic components to maintain brake pressure, but power loss after engine shutdown may cause automatic brake release. Last year, I parked on an overpass slope and only relied on auto-hold after turning off the engine - my car rolled half a meter and hit the guardrail due to electronic system failure. Especially during rainy days or on slopes, the mechanical handbrake provides dual protection by directly locking the rear wheels. I've developed the habit of always engaging the handbrake before shutting off the engine - those extra three seconds are far better than dealing with an accident. Regular checks of tire pressure and brake pads are also essential, especially for older vehicles where these details require extra attention.
