How does the Smart Welcome System work in the Kia Sorento?

I'm interested in purchasing a Kia Sorento and I've heard about the Smart Welcome System. Can you provide more information on how it works?

The Smart Welcome System in the Kia Sorento is a feature that uses a sensor to detect your vehicle key as you approach the car. Once the key is within range, the system will automatically unlock the doors and turn on the exterior lights, creating a seamless and convenient entry into your vehicle.

In addition to unlocking the doors and turning on the lights, the Smart Welcome System also activates the power adjustable driver's seat to your preferred settings, making getting in and out of the car even easier.

If you're worried about accidentally leaving your key inside the car, don't worry - the system will detect the key and prevent you from locking it inside.
