The TPMS malfunction indicator will illuminate after it blinks for approximately one minute when there is a problem with the Tire Pressure Monitoring System. If the system is able to correctly detect an under inflation warning at the same time as system failure then the TPMS malfunction indicator remains illuminated after blinking for approximately 1 minute.
We recommend that the system be checked by an authorized Kia dealer to determine the cause of the problem.
