I don’t see an option to blow normal vents and the footwell at the same time on my dash. Am I nuts or am I missing something? Also, I had the interior circulation locked “on” on my 2014. Seems to automatically turn off after a while on my 2021. Any way to fix this?

 

Having Recirc on all the time is a safety issue, especially in newer vehicles that are sealed WAY better than older ones. There is no way to disable the Recirc from turning off.

 

Safety issue, can you explain?

 

CO2 or other gasses just circulating…honestly a big part of why I kept recirc on in my other vehicle was because it always smelled fresher inside. I guess having cabin filters and stuff, I was only realizing it wasn’t on because the button wasn’t lit. Come to think of it I’m not smelling those outside smells.

pertaining to the foot and face blowing at the same time…just have to push both buttons on the screen, I’m an idiot. I thought there would be a third button like there is on a dial etc.

 

It disables after a time because the humidity can build up, resulting in reduced visibility from window fogging.

It also does so to reduce buildup of carbon dioxide. Carbon dioxide is odorless, but you will notice it building up before it becomes life threatening. A “stuffy” atmosphere is one that is high in CO2. You’ll notice it as you’ll be breathing harder and you’ll feel like you’re not breathing enough. (But it can also result in reduced mental capacity as it builds up.)

The 3rd reason is that in the event of an unplanned exhaust leak, bringing in fresh air on occasion ensures that more dangerous gases, particularly carbon monoxide, do not build upon the cab. Carbon monoxide you will NOT notice until it is too late. You’ll get a bit sleepy and maybe even a bit confused, and then pass out without much warning. (If you’re driving you may wreck.) If you continue to be exposed following unconsciousness, you might wake up dead. If fresh air is occasionally introduced to the cabin, it significantly reduces the chances that carbon monoxide builds up to life or health threatening levels in the event of an exhaust leak.

 

To answer the OP’s question, I’ve been able to enable two different vents at a time, and actually even all three at once. Simply push the selector button on the dash, and when the selector indicator pops up on the 8” or 12” center stack screen, tap each one you want to enable or disable. It’s easiest to do that via the screen itself.

 

Thank you, I appreciate it. You’d think that’d be common sense. But, with my old trucks having a third button or option on a dial, I naturally looked for a button showing both upper and lower venting.
