At the touch of a button, Downhill Assist Control (DAC) [1] helps the GX descend slippery and steep grades. When engaged, DAC works with the Anti-lock Braking System (ABS) and Active Traction Control (A-TRAC) to help keep the GX at a slow, constant speed and prevent the wheels from locking up. Virtually all the driver needs to do is watch the road and steer.
