What is the function of the hold button in an automatic transmission car?

[DePaisley]

Automatic transmission car hold button is the automatic parking function. After the function is activated, in case of a brief temporary stop, the car can be stopped by the brake pedal. Temporary parking: When the vehicle is temporarily parked and needs to be restarted after a very short period of time, this type of parking is completed by the ESP-controlled brakes. The computer will use a series of sensors to measure the levelness of the vehicle body and the torque of the wheels, make a judgment on the tendency of the vehicle to move, and apply an appropriate braking force to the wheels to keep the vehicle stationary. Exceeding the time limit parking: When the temporary parking exceeds a certain time limit, the braking system will switch to mechanical rear-wheel parking (activating the electronic parking brake) to replace the previous four-wheel hydraulic braking. When the vehicle is about to move forward, the electronic system will detect the pressing force of the accelerator pedal and the travel of the clutch pedal in manual transmission models to determine whether to release the brake.

When I first started driving an automatic car, my friend taught me to use the hold button, which turned out to be a lifesaver on hills. On steep mountain roads, pressing it keeps the car firmly stopped without worrying about rolling back. Driving to work daily, I often encounter sloped traffic lights where I used to exhaust my foot pressing the brake hard—now it's much easier. Not only does it save effort, but it also prevents slipping when starting, making it extra safe. For long waits at red lights, this feature avoids frequent braking and part wear. I must say, getting into the habit of using hold has made me feel much more at ease in city traffic or while traveling. Just be careful not to press it by mistake while driving, as it can affect acceleration—best to get used to the operation first.

As a mom who often drives with kids, I have a deep appreciation for the hold button in automatic cars. When parking on the ramp outside the kindergarten, without this feature, the car might roll back, leaving me flustered. But with hold engaged, the car stays put, allowing me to focus on helping my kids in and out safely. It's like having an electronic assistant that frees my right foot from constant brake fatigue. Especially in places like mall underground parking ramps, starting and stopping becomes much smoother. My husband used to complain I was overly cautious, but now seeing how relaxed I am, he's started learning too. Personally, I think it's a thoughtful design for family drivers - worth using regularly, just remember to gently press the accelerator when disengaging.

Having driven for over a decade, let me briefly explain the purpose of the HOLD button: It mainly helps temporarily brake an automatic transmission vehicle. When stopping at a red light or on a slope, pressing it prevents the car from rolling back without needing to keep the brake pedal depressed. Unlike a regular handbrake, it directly keeps the car stationary and automatically releases when starting, which is quite smart. Especially in urban traffic jams, it reduces driving fatigue. I recommend trying it frequently in the car; once familiar, you can maximize its benefits.

I commute by car every day, and being stuck in traffic for half an hour is a common occurrence. I've found that the automatic transmission's hold button is a real labor-saving gem: press it at red lights or during traffic stops, and it frees up your right foot, no longer needing to press the brake for long periods and avoiding soreness. I used to get nervous about starting on hills, afraid of rolling back and causing a rear-end collision, but now it's effortless. It's not just convenient; it also enhances overall driving comfort, such as reducing foot fatigue on long drives. From my personal experience, combining it with cruise control is even more efficient, but be careful to avoid accidental use on highways. After getting used to it, there's no noticeable impact on fuel consumption. In short, I highly recommend commuters make the most of it.
