The tire pressure monitoring system reset button for your 2016 kia optima should be either in the glove box or beneath the steering wheel. resetting the light requires no special tools and needs to be done after you check to make sure the pressure is accurate in all four tires. this also needs to be done after rotating the tires unless the system does it automatically. with the parking brake on, turn the key in the ignition to on without starting the engine. hold down the reset button you previously located until you see the tpms light blink three times in the cluster. it will generally take a few minutes for the sensors to send appropriate signals to the ecu. drive the vehicle for 30 minutes to complete the resetting process. if you need to reset the light because a sensor has been replaced, you'll need to do each tire individually with the help of a scan tool connected to the obdii port.
To reset the tire pressure sensor in the 2016 kia optima, begin with the ignition in the on position, without the engine running. locate the tpms reset button below the steering wheel. hold that button down and until the light blinks three times and then stops. as soon as it stops, start the engine and allow the vehicle to run 20 minutes.
