How to Use Hill Start Assist?

How to use hill start assist: When parking on a slope with the gear in drive, releasing the brake pedal will automatically activate the hill start assist. In some vehicles, this function activates automatically after pressing the brake pedal. Hill start assist allows the car to start on a slope without using the handbrake and prevents rolling back, but the braking time is only a few seconds. There is still a risk of rolling back if the throttle is not applied in time. How hill start assist works: When starting on a slope, the moment the foot leaves the brake pedal to press the accelerator, the HAC system automatically maintains brake oil pressure for two to three seconds, equivalent to the brake still being pressed, so the car will not roll back. When the accelerator is pressed, HAC's control of the brake automatically ends, and it does not release all braking force at once but gradually reduces the braking force, allowing the car to start as the driver presses the accelerator.
Using hill start assist is actually quite simple, especially when I drive an automatic transmission car. Simply put, when you stop the car on a slope and prepare to start, the system will automatically help you brake for a few seconds after you release the brake pedal, preventing the car from rolling backward. This gives you enough time to press the accelerator and accelerate. I remember driving on congested uphill roads, and it saved me from worrying about the car behind getting too close, making it much safer. However, it's worth noting that some manual transmission cars also come with this feature, and the usage is similar. But it's best to confirm whether your car has it enabled—usually, there will be an indicator light on the dashboard. I recommend beginners practice several times in an open area to get used to the transition feeling, so they can drive more confidently on the road. After all, the biggest fear during hill starts is rolling backward and causing a minor accident.
