Hyundai Ioniq. Low Tire Pressure Telltale

When the tire pressure monitoring system warning light illuminates and a warning message appears on the instrument cluster LCD, one or more tires are significantly underinflated. The LCD position indicator will show which tire is significantly underinflated by illuminating the corresponding position light.

If the pressure in any of your tires is low, reduce speed immediately, avoid sharp turns, and expect increased braking distance. You should stop and check the tires as soon as possible. Inflate the tires to the correct pressure specified on the vehicle certification label or the tire pressure label located on the outside of the driver's side center pillar.

If you cannot reach a service station or if the tire does not hold the air you have added, replace the low-pressure tire with the spare tire.

The low tire pressure LCD indicator will remain on, and the TPMS malfunction indicator may flash for one minute and then remain on until the low-pressure tire is repaired or replaced on the vehicle.

NOTICE

The spare tire is not equipped with a tire pressure sensor.

CAUTION

In winter or cold weather, the TPMS warning light may illuminate if the tire pressure was set when the outside temperature was warm. When the outside air becomes colder, tire pressure drops. Similarly, if the outside air becomes warmer, tire pressure will increase. As you drive your vehicle, the tires will heat up, so tire pressure will increase. Check and adjust tire pressure regularly before driving to ensure the vehicle is operating at the correct calculated pressure.

WARNING

Low Tire Pressure Damage

Significantly low tire pressure makes the vehicle unstable and may contribute to loss of vehicle control and increased braking distance.

Continued driving on a low-pressure tire may cause the tire to overheat and fail.
