When first started the tool bar on dash board shows up and has a -64d next to it

It looks like it is 64 days past due for oil change/servicing according to driving habits, mileage average, etc. If service has already been performed you can reset the service reminder yourself by pressing the left button on the odometer twice within about 2 seconds after turning key to ignition position, (the position just before starting engine). Then turn key to off position without removing key. Press and hold left button on odometer once again while you turn the key back to ignition position and the service reminder will reset to next service interval in about 10 -12 seconds. Just don't forget to press and hold the left button. It took me a couple of tries too :)
