The 2023 Kia Rio comes standard with pedestrian detection, which means that if you’re driving and a person is walking in front of you, the car will automatically apply the brakes. However, not all models have this feature; it's only available on some trim levels.

It's important to note that this feature does not always work properly. If you're going at a high speed or in an area where there are other cars around, this feature may not be able to help you avoid hitting pedestrians. It's best to leave yourself plenty of room so that there is no chance for error when using this feature.

The adaptive cruise control uses radar to detect vehicles ahead of you. The system maintains a safe distance from the vehicle in front, and can be used in stop-and-go traffic. It can also be used on highways, where it will maintain a safe speed without your having to press any pedals. Adaptive Cruise Control is designed for use with clear weather conditions, including rain or snow.
