Tire pressure malfunction?

[Dbj77]

is this a malfunction or do I really have a tire pressure problem? How do I reset this?

I believe this happens when those two started low, or we're low the last time the sensors registered (last trip).

Sensor reset used to be in one of the service menus - assume it's still there in V9.

The ambient temperature dropped and the tire pressure dropped with it. Put air in the tires to bring them back up to 45 psi.
