What does the AWD lock button do in the Kia Sportage?

I've noticed that my Kia Sportage has an AWD lock button. What exactly is its purpose and when should I use it?

The AWD lock button in the Kia Sportage temporarily locks the differential between the front and rear axles, providing better traction in slippery conditions. You should use it when driving on snow, ice, or other low-traction surfaces. It is not recommended for use on dry roads.

It's essentially a 4WD mode, designed for situations where all four wheels need to work together for maximum traction. It's best for off-roading and deep snow or mud. However, it should not be used on dry pavement as it can cause damage to the drivetrain.

The AWD lock button is a helpful feature in the Kia Sportage, but it should only be used in specific situations where extra traction is needed. It's important to turn it off once you're back on dry roads to avoid damaging the vehicle.
