This is a pet peeve of mine. They (and other manufacturers) make you go to the dealer for some things, others you can control in the set up menu. Anything that can be turned on or off should be owner controlled. As I posted in another thread, I don't want to hear seat belt chimes. Same deal. It's just a scam to make money.
To me that would be on par with disabling the Air Bags or disabling the emergency brake..
DRLs were very effective when they initially did tests on them (30+ years ago) because they were different - only the test vehicles on the road had headlights on during the day. Now, in the US, probably 1 of 3 cars or more has them on. No real difference in accident rates. Hardly on par with airbags. Unless you count on them to protect the folks that drive at night without lights because they don't think to turn lights on. In Canada it might be very illegal to run without DRLs. Not so down here.
So you want to disable DRL? And you think that a licenced dealer will just disable them for you?
I suppose that the highway traffic act and the concept of liability are alien to you.
for the fun of it, call the service desk at the local dealer and tell them that you want them to disable the day time running lights.
