For the last couple of years I haven't driven the CTD very much. Been missing it recently and started driving it again. I now notice that the cruise control works fine until I drop down to approximaetly 37 MPH and then it stops working. I didn't recall this happening before. Is there a min. speed that cruise works? If this doesn't seem right, any ideas on what to look for? I know, why would you use cruise at that low of a speed. The road I travel daily has a stretch that drops to that speed and goes for a few miles. No traffic to speak of and cruise just simply can be used reasonably. Thanks
