The CX-5 cruise control down shifts to slow the vehicle on hills. This is OK if you want it, and can be the only safe way on a long hill. For short hills especially where there is a steep but short uphill right after a steep down hill you may not want it. It exercises the transmission a lot, and slows the car down so it will use more gas to clime the next hill. (You may be willing to let the car go 5 mph faster on the way down and then lose it on the way up.)
I found the easy way around this is to move the shift lever to the M position as the car starts down, thus holding it in 6th gear. At the bottom move it back to D and let it chose the gear or gears to climb.
