What Does the 'Lock' Button Do on the Kia Sorento's Four Wheel Drive System?

I've noticed a 'Lock' button on the four-wheel drive system of my Kia Sorento, but I'm not exactly sure what it does. Can you explain its purpose and when I should use it?

The 'Lock' button on the four-wheel drive system of your Kia Sorento is used to engage the center differential lock. This allows for equal power distribution to all four wheels, providing better traction in off-road or slippery situations.

I find that using the 'Lock' button is most effective in deep snow, mud, or when driving on uneven terrain. It's important to note that the 'Lock' feature should not be used on dry, smooth roads as it can cause unnecessary wear and tear on the drivetrain.

It's also worth mentioning that using the 'Lock' feature on paved roads can make steering more difficult, so be sure to turn it off once you're back on smooth surfaces.
