What does the tpms light mean on a hyundai elantra?

If the TPMS light turns on in Your Hyundai Elantra that means that one of the tires pressure is low. TPMS stands for tire pressure monitoring system. When this light turns on You should check each tire to make sure that there are not any screws, nails, or obvious holes in them. After that You should fill up the tires to the recommended PSI that is listed on the sticker in the driver's door jamb. Once all the tires are filled You can press and hold the TPMS button that is on the dash and that will reset the system and turn off the light. It is important to keep Your tires filled to prevent them from having uneven wear.
