What is the key on/off procedure to get the overall truck run time to show on the dash...think its in the odometer display. I can't find this in my manual but I've done it in the past...must have found the info in a forum such as this but I can't find it now.
Thanks in advance

 

I'd play with the overhead, but could be wrong.

 

Might not be the same, but on the 05 you turn key on then hold reset button for trip meter in for 6 seconds and the runtime shows.
