What is Kia's Smart Power Liftgate feature and how does it work?

I've heard that the Kia Sportage has a Smart Power Liftgate feature, but what exactly is it and how does it function? I'm curious to know if it would be useful for me.

Kia's Smart Power Liftgate is a convenience feature that allows you to automatically open and close the rear liftgate with just a press of a button or a quick kick under the rear bumper. It uses sensors to detect your proximity and movement, making it easy to access the trunk even when your hands are full.

I've found the Smart Power Liftgate to be incredibly useful for when I have my hands full with groceries or other items. It's also great for when you're in a rush and can't fumble with keys or buttons to open the trunk.

One tip for using the Smart Power Liftgate is to be aware of your surroundings before attempting to open or close it. The sensors can sometimes be sensitive, so make sure there is enough clear space behind your vehicle to avoid accidentally hitting anything.
