What does the Eco mode do in a Kia Soul?

I recently purchased a Kia Soul and noticed a button for Eco mode. What exactly does this mode do and should I be using it?

Eco mode in a Kia Soul optimizes fuel efficiency by adjusting engine and transmission calibration. It may also reduce the vehicle's air conditioning and other accessory power consumption. It's a good idea to use Eco mode if you want to save gas and reduce emissions.

Eco mode is really helpful when driving in stop-and-go traffic. It reduces engine torque and adjusts gear shifts to save gas and make the ride smoother. I always use it in city driving.

Be careful when using Eco mode on the highway, as it may decrease performance and acceleration. It's better suited for city driving and can save you some money on gas.
