The last time I started my car was a week ago Sunday.

I moved it out of the garage and back in to make room for a table saw. When the car to move it back in, during the preglow, the red and green lights on the interior mirror started to flash as if the DAS was disallowing a start. I removed the key from the switch and locked and unlocked the car with the remote, and it started.

Yesterday, I was going to drive the car to warm it up, and it did the flashing again. But this time I noticed that the dashboard display dimmed very greatly while engaging the starter. (The lamps were flashing then as well, so I knew that it wouldn't start.)

Since it had been some time since the car had actually been driven, I wouldn't be surprised that the battery couldn't keep up. Hopefully this is the entirety of the problem.
