Took '05, (package 5) to dealer for 70k maintenance yesterday for trip tomorrow. Got new tires, this, that, the other. On the way home the headlight leveler warning comes on, goes off, comes on, goes off. Back to the dealer, he says it's just "it's time". I am driving 500 miles tomorrow for vacation. He says the headlights are properly aligned and it's probably just the sensor and I can have it fixed when I return because this won't be quick. I don't know if I can tolerate that darn chime going off every 10 minutes for 1000 miles. Is there any way to turn off the volume of the chime?
