This morning I turned the heater on and hit the recirculate button (gotta keep that new car smell...) and noticed that it had turned off (recirculate). Hit it again and made sure to observe the time. It turns off after 5 minutes. I found an article for a Tacoma and it looks like if you hold the button for a few seconds recirculate will stay on. I looked through the manual but didnt find anything like this. Anyone know if there is a trick to keep it on?
