From the 2003 manual....
Your vehicle may have an air inflator system. The air
inflator is capable of re-inflating the vehicle’s tires if
they have been deflated. You can also inflate things like
basketballs, air mattresses and bicycle tires.
Just looked at my old hose in the garage attic (took my air ride out and put in coils) and on the end with the gauge you should be able to screw it right onto the valve stem of the tire. I know a lot of the folks on here that take their trucks off road air their tires down for better off road traction and then those with the air ride will air the tires back up again using the hose.
