'08 Sonata Limited. TPMS letters came on after plugging in a DVD player. Will not go out after all devices are unplugged. Just the TPMS letters and not the tire symbol. The manual refers to this, but not about resetting. Is there a "reset" feature that I can use or is it a "back to the dealer" type fix?

 

Sorry but you have to go back to the dealer. There's a problem with the system and they dealer needs to use a scanner to reset it.
