” she is saying that their Jetta has only an on or off selection no inbetween.”
Thank you.
If only our fellow FReeper read the OP which said:
“We THOROUGHLY READ (emphasis mine) the part on lights, so it won’t be a problem for us, as we will only count on the regular headlights at night, but people who don’t get a chance to read the vehicle’s manual before they drive it might not know, so it seems to me it could be dangerous.”
If this thread gets people to read their manuals before driving, it could save someone from getting hurt.
Owners manual... Near as I can tell, VW does not have an on line download of the owners manual so I can't use this source to figger our the light issue you described.
I did find the below forum threed discussing daytime running light stuff for some recent year Jettas. Weird light stuff! This forum could be something for you to join up for asking some VW enthusiasts on this or other questions or discoveries you have over time.
