This is why Canadian's who purchased a US model have to have full-time fog lights or some other intervention to keep some form of "headlight" on at all times. (Again, a Canadian resident can correct me if I am wrong.)

CO/2 or energy savings from having the DRLs off all the time. I honestly don't think it is all that much, given the fact that when the vehicle is moving, it can probably generate enough surplus energy to make up the difference. I would be interested in a study on the subject though.

Mike,

Thanks for the reply and for your may useful posts on this forum, all of which I read prior to my TCH purchase last month.

Re. "I believe..........." : Yeah, that's pretty much what I have now come to believe, also, but it would be nice to know with certainty, for if it's so then we have a reliable way to turn all of the lights off for sure that does not depend upon auto functions working or upon other actions such as the way the doors are locked or the order in which the the doors are opened or closed, etc. Here's hoping we hear from someone who knows for sure.

Re. The savings from DRL's off............. Oh, I agree it's not much. I was only speculating as to why someone might want them off. I know lots of folks these days who are absolutely fanatical about making inconsequential energy savings. They do it out of idealistic fervor rather than from any practical consideration.
