An Adaptive Forward Lighting system, a first-time application on a Cadillac, which automatically adjusts headlamp direction up to 15-degrees for improved night driving vision
I beilieve the Dynamic Passenger Sensing System is a sensor for the passanger airbag. Anyone back me up on that one?
By the way, I set in a 2006 XLR today, and you know how GM doesn't like to release everything.
Anyways here are some more changes for the 2006 XLR:
The Wood Trim goes all the way up to the CD changer slot, (above it)
The mirror is changes and says Passenger Airbag, just like the Escalades do.
There is no airbag light on the center consul anymore.
They have put a black filler plate over where the key use to be.
They have added a GM logo on the outside of the car behind the driver side and passenger side, like the 2006 corvettes.
Also I noticed in the export modes, they have a feature that if you leave your windows down and put your hand inside the car the alarm will go off, I though that was pretty cool.
Also the new gold mist color looks ok, almost like a cream.
