Another really inane feature...(Tire Fill Alerts Disabled)

OK, I get up this morning to go drive the car. It's a rare 28 degree day here in NC. The car gripes that the right side tires are low in pressure. Oddly this is one of these oddball ones where the left side tires are also at 30 psi but they are fine. No problem, says I. I drive the truck over close enough to my air compressor for the hose to reach. I'll use the snazzy "blow the horn when you've put in enough air" feature the dealer showed me. It's grayed out.

Now, I get out the manuals to see why. Have I ever told you how much the RAM manuals suck? I've seen better English in Nissans and Toyotas. The entries are cyclical and inane and lack useful information. I may have misunderstood it but I think it says the feature is disabled if you get a low pressure alert. What? That's the one time you'd really like to use it. Anyhow, put air in the tires by going back and checking the dash display periodically.
Still the tire pressure feature in the UConnect Apps is grayed out. NOTHING happens when you poke at it while in park. If you poke it while you're in Drive it warns you that you can't use it while in motion. (Yeah putting the air hose on the spinning is going to be difficult anyway).

Later on it'ss still grayed out. I KNOW it did work before as the salesman demoed it to me on THIS truck before I left the lot. Hmm... poke around the other setup menus. Under DRIVER ASSIST there's a feature that disables this. WHY? I mean, if you don't want to use it, don't poke the button. Not sure why it needs a secondary disable and I'm not sure how it got turned off.

Did I tell you how much I hate the RAM manuals.

According to my build sheet my truck has this but it’s not listed in my uconnect setting anywhere. Under the driver assist menu it says 7 items in list ( or around there ) but it only shows 6. ( shows one less that the items in list number ). I suspect the tire fill assist is the missing item but have no clue how to get it to show.

Either way I carry a digital tire gauge in the glove box.

I haven't even seen that option on the Rebel 8.4 setup - all my imports had the feature though. Will have to check the build sheet

Putting air in and going back to check the dash readout periodically will not work since you have to be in motion for the readings to update.
That certainly does not seem to be the case in my truck. The wheels have to spin to keep the TPMS sensors charged up, but they will report while standing still or else the Tire Fill Alerts would never work anyhow.

Clearing two things up from above -

1. the TPMS sensors are battery operated - there's no charging while in motion
2. The TPMS Sensors 'sleep' when no motion is detected to save battery life
3. the Sensors will transmit PSI data 'live' to the dash if they're awake after a drive - that's how the tire fill alerts work

I drove to gas station with low tire pressure and parked (with vehicle still running) to add air to tires. Oddly I got the horn beep to tell me when I had enough air pressure and the numbers moved up on the screen as the tire pressure increased as wifey was calling it out to me.

I don't know what is checked where, let me know and I will look and see what is turned on/off etc...
