Anyone know how to adjust the rails on the Traverse? Every other car I've had, it's been pretty straightforward, but I can't find a lever or way to move the cross rails. The ones I have were installed at the Chevy dealer when I bought the Traverse.

BTW - I love the Traverse!

sorry I dont know the answer.
Ive ordered a 2010.- and requested the roof cross rails.
and I told my salesman- not to install the cross rails.
I only want them on when I plan to use them...

This raises another question... are they hard to put on-- off?
