The TPMS malfunction indicator will illuminate after flashing for approximately one minute when there is a problem with the tire pressure monitoring system.
Have the system checked by an authorized HYUNDAI dealer as soon as possible.
NOTICE
If there is a malfunction in the TPMS, the low tire pressure warning light will not illuminate even if a vehicle tire is under-inflated.
NOTICE
The TPMS malfunction indicator may illuminate after flashing for one minute if the vehicle is near power transmission lines or radio transmitters, such as police stations, government and public facilities, radio stations, military installations, airports, transmission towers, etc.
In addition, the TPMS malfunction indicator may illuminate if anti-skid chains are used or if electronic devices such as computers, chargers, remote starters, navigation systems, etc. are used. This may interfere with normal TPMS operation.
