How do I open the gas tank on a 2021 Kia K5?

I’m borrowing my big sister’s 2021 Kia K5 and the gas tank is nearly empty! But I can’t seem to figure out how to open the gas tank and I’m too embarrassed to ask her—she’ll never let me live it down! How do I open the gas tank on a 2021 Kia K5?

We understand! Siblings can be that way sometimes. But thankfully, opening the gas tank on a 2021 Kia K5 is easy peasy once you get the process down. Just follow these simple steps:
  • Turn off the engine first
  • Open your driver’s door to automatically unlock the gas tank door
  • Press slightly on the far right side of the gas tank door
And voila! That’s all there is to open the gas tank door on a 2021 Kia K5 sedan. Just fill up the 2021 K5’s 14.8-gallon gas tank, and your sister will be impressed you did it all on our own!
