2016 Toyota Mirai: This Water Is Not for Drinking
by Ed Hellwig, Executive Editor on June 14, 2016
Just to the left of the steering wheel in our our 2016 Toyota Mirai is a cluster of buttons. You might recognize the buttons on the outside (auto high beams, instrument panel brightness), but that one in the middle is unique to the Mirai. So what does it do, exactly?
It's the water purge button. As you may or may not know, the sole byproduct of the fuel cell's conversion of hydrogen into electricity is water. Under normal use, that water is expelled through a discharge pipe underneath the car, so it might leave a small puddle much like the air-conditioning system of a normal car does.
It's an automated process that you don't need to think about most of the time, but the designers of the Mirai realized that there might be times when you want to get rid of the water proactively before it drips where you don't want to. For that, you simply hit the button and wait 15-20 seconds or so. The total amount released is pretty minimal, so should you ever get stranded in the desert with nothing to drink, the Mirai isn't going to be your savior.
