No, its none of those ....its that the rear defrost is on....lol. You nay have just accidentally hit it.

CHECK AND SEE IF YOU HAVE TAIL LIGHTS USED TO BE FUSED TOGETHER

CHECK COOLANT LEVEL IN COOLANT EXPANSION TANK.SOUND LIKE LOW COOLANT WARNING LIGHT.

Assuming your Kia is equipped with a manual transmission, those arrows are telling you to shift into a higher gear to save fuel.

then it seems a loose connection somewhere behind your dashboard may be your problem, get an qualified electrician to check it out,
good luck

Check TCM for codes.

this indicates an automatic gearbox problem associated with the winter mode switch
does your car drive ok or are you stuck in ultra low gear with a max speed of about 10mph??

That's for your tire pressure on your car (TPMS). Most times when the tire pressure goes below 25psi, the light on your dash goes on.
You may have a nail in your tire. Or, they are just low.
Air them up to 35psi and the light should go out. Sometimes, there is a pressure senor in the spare tire. To be safe, check the air in the spare tire also.
