Keys
Smart key
Never leave the keys in your vehicle with unsupervised children. Leaving children unattended in a vehicle with a manual ignition key or a smart key is dangerous.
Children imitate adults, and they could press the start button. The key would allow children to operate power windows or other controls, or even make the vehicle move, which could result in serious bodily injury or death.
Aftermarket keys
Use only Kia original parts for the ignition key in your vehicle. If you use an aftermarket key, the ENGINE START/STOP button may not return to ON after START. The starter will continue to operate, causing excessive current in the wiring, which could result in a possible fire.
Never leave the keys in your vehicle
Leaving children unattended in a vehicle with the keys is dangerous, even if the vehicle is in ON. Unattended children could press the start button and may operate power windows or other controls, or even make the vehicle move, which could result in serious bodily injury or death. Never leave the keys in your vehicle with unsupervised children when the vehicle is running.
