Hi Shinytop,
There is a thread here somewhere that someone complained that they were
turning off after 4 minutes of "on time." (Not in Range Mode)
They were told it was normal - I do not think it is normal.
I think mine are on all of the time while I am driving.
The next best substitute would be to turn on your parking lights.
They are the same as DRL with the possible addition of some tail lights...

Edit: Here was the earlier thread -
Where do I go to get Daytime Running Lights back???
