To shift from Fahrenheit to Celsius on Your KIA Rio, press the OFF button and the AUTO button together for at least four seconds. Now, the display will change from Fahrenheit to Celsius or the other way around.
Also, if you disconnect the battery and let it breathe for a while before reconnecting, the display will go to the original form, i.e., Centigrade or Celsius.
To know more about your KIA RIO, please refer to this owner's manual https://www.manualslib.com/manual/740114/Kia-Rio.html?page=195

Just my first thought. I would think the transmission might be slipping. Another thought if it has been setting a while wonder if you have brakes or emergency brake sticking. If they were sticking all the time you would be able to smell them. Maybe just sticking and release when the car gets moving. I know if transmission fluid is low it will cause them to slip also.

I will say I have never had a kia and the vehicle I know of say the transmission oil should be at a certain temperature to check level under the car on sealed transmission..(because oil expands at higher temparature.) The way I have seen you have to add fluid under the car also. So Kia is somewhat different.

You probably have a wheel, suspension or tie rod problem in the front end - you need to have it checked immediately by a shop.

The transmission control module is responsible for correct shifting of transmission.it is on side of tranny. the throttle position sensor takes all the necessary measurements and sends it over to the Electronic Control Module on transmission to make it shift, if its ok! Try by changing the shift module on transmission. If this will not work check or change the TPS and check for a bad wire also. Hope this helps you out! God-Bless!

Hi,

Always use the OEM oil filters they are always the best, and just check your oil recommendations in the service manual.

But you can use a fully synthetic oil which is the best grade off oil to use.

Thanks

There are Three things that cause this code other than vacuum lines and hoses, the fuel tank pressure sensor, monitors the pressure in the fuel tank and times the vacuum decay, The canister purge valve and the canister close valve, these are all maid to be tested with a scanner but you can Do this, locate the charcoal canister and find the valves have someone turn the switch on while you feel and listen for a click. You can also check with an ohmmeter just check for continuity. If the fuel tank is rusty on top there could be a pin hole in it. I hope this helps. Take care.

what i heard that it is like removing it from under the car which is not possible without lifting the 4 wheels. Also you may want to first do this before removing the alternator, even the multimeter shows the alternator failed test. Simply go underneath the car to check for the wire that comes out from the alternator and goes to the battery to charge it up. This particular wire that is coming out from the alternator to charge up the battery is completely fused or burnt.
