Occasionally in the past the TPMS light has come on for a moment then gone out so I haven't thought much about it, but today after riding about 5 minutes, the TPMS warning light came on, and stayed on for about 10 minutes. After 10 minutes it went out, and for the rest of the hour and 15 minute ride it stayed off. Not sure if I should be concerned about it. All the manual says is that if the light comes on and stays on, to have it checked. Any advice?
