how do I operate the air pump provided by Volvo in lieu of a spare tire?

Helpfull but I did as you suggested and pushed button which I assumed would initiate the fill process. The the tire started to lose air when the button didn't seem to work perhaps because I didn't screw on schrader value tight enough. I'll try againThanks

Yup. Try again and make sure you have a good connection to the tire air valve. Do they give you Fix-a-flat to put in the tire? If there is a leak of any size the tire will go flat again, quickly.

Ya they can be touchy. Make sure yr connection is good and yr totally vertical not flexing the valve.Then u should be ok.

Make sure you open up the valve aswell.
