    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.

    Does your car have the Tire Learn Procedure like my Cobalt?

    The attached document is a bit confusing but thought I would include it.


    Here is what you need to do if you do not have a TPM learn tool.
    Put the vehicle into learn mode, then starting with the LF tire, let air out of the tire until the horn sounds (about 5psi worth), then move to the RF tire, repeat, RR tire, repeat, LR tire, repeat, you should hear the horn sound once or twice when learn is complete.
    Set vehicle tire pressure per placard on LF door jamb.

    You only have a limited amount of time before the vehicle goes out of learn mode, so don't dawdle, be prepared to move quickly, maybe have the valve stem caps off before starting the process, have a small screw driver or similar tool to let the air out of the valve stem.

    It also helps if the tires are fully inflated and not low on air before you start.
