I am looking at a friends 2005 sts to purchase, but have a question concerning the control panel digital readout. When the car is started the digital readout displays trunk open, check check tire monitor, etc... The readouts can be cleared by pushing the upper left button adjacent to the display area. The Owner said after he replaced the bad battery the readout started to display as noted above. Before he changed the battery the readout never malfunctioned. He has the CD and all manuals for the car and said all I need to do is view it to walk me through the resets. I am a little worried there is something else wrong. Does anyone have any info for my concern?
