  • Before touching the fuel nozzle, discharge potentially dangerous static electricity by touching a metal part of the Kia Seltos at a safe distance from the fuel filler neck, nozzle, or any other fuel source.

  • Do not reenter the vehicle once refueling has started. Touching, rubbing, or sliding against materials such as polyester, satin, nylon, or other fabrics may generate static electricity. A static electricity discharge can ignite fuel vapors and cause rapid burning. If you must reenter the Kia Seltos, discharge static electricity again by touching a metal part of the vehicle away from the fuel filler neck, nozzle, or gasoline source.
