Gasoline Particulate Filter (GPF)

The Gasoline Particulate Filter (GPF) system removes soot from the exhaust gas. Unlike a disposable air filter, the GPF system automatically burns (oxidizes) and removes accumulated soot during driving.

However, frequent short trips or driving long distances at low speed may prevent accumulated soot from being automatically removed by the GPF system. If the accumulated soot reaches a certain amount, the GPF warning light () will illuminate. Re-operate the GPF system: the vehicle should be driven for more than 30 minutes at a speed of 80 km/h or higher. Make sure the following conditions are met: safe road conditions, gear 3 or higher, and engine speed of 1500-4000 rpm. Driving at 80 km/h or faster for the recommended hours will allow the GPF system to return to operation and stop the GPF warning light.

If the GPF warning lamp remains on or the warning message "Check exhaust system" appears even after driving at the recommended speed and for the recommended hours, visit a professional workshop and have the GPF system inspected. Kia recommends visiting an authorized Kia dealer/service partner. Continued driving with the GPF warning lamp on may damage the GPF system and reduce fuel economy.
