Its us who have the indirect TPMS system looking at balance differences between the wheels that would not pick up a loss of air pressure in all four tires.
For your info - and I don't know how this translates into the low air pressure alarm point in your direct TPMS - I currently have a slow leak in one tire with the alarm on our indirect TPMS coming up about once per week when the air pressure has fallen from its normal 36 psi to 27 psi.

that's quite a drop. I would have thought 3-4lbs max and the warning would come on. When the warning is activated, does the nav screen go to the TPMS screen and make one (or more) tires a different color? or do you get a 'ding-ding' sound and a yellow triangle on the screen in front of you?
