Recent Metris purchase. We live in the mountains with 7 and 8 percent grades. I need to find a efficient way to descend without excessive braking. Any help would be appreciated. We were told at the dealership to use cruise control. We did and it ended up scoring the rotor. I have been using the paddles to downshift into a lower gear. This has help somewhat. The Metris is a beast and gets going downhill really quick. I need to find a solution.
