I went to move the car in the garage to get more space to assemble a cabinet. The car wouldn't start because the battery ran down again. I know I have to drive the car at least once a month in order to keep the battery charged. The last time I drove the car was February 9th and I have been starting the car just to move it forward in the garage. I charged the battery for several hours and then started the car. I saw that the tire pressures were gone and two dashes displayed for all four tires. I thought I would try deflating a tire and see what happens with the display. I pushed in the valve for the left front tire and checked the tire display. I saw 26. I added air and saw 29. I deflated the other three tires one at a time and saw a pressure displayed. I then inflated every tire to 30 psi. I didn't have to go through the tire learn process holding the two buttons down at the same and then scrolling down to Tire Learn.
