Otherwise, the tire pressure warning light may not come on even if the tire inflation pressure is low, or it may come on when the tire inflation pressure is actually normal. LS17025 LS17018 If the tire pressure warning light does not blink slowly three times when you push and hold the tire pressure warning reset switch, initialization has failed and the tire pressure warning system may not work properly.
