Very important point Morich, thank you! For adding:
Use always the tow-mode on the gear lever (push the button). This will affect that the gearbox is shifting down automatically so you don't need to break always. This works quite well on interstates. But f it's very steep and a long way down (e.g. Sierra Nevada Passes; Beartooth Pass MT & WY, or from Bighorn National Forest to Lovell WY; US 14 Alt) it's better when you shift manually down. You do it this way: First slow down to the right speed and then shift manually down to the right gear, that you feel the vehicle is "hold" by the gearbox and you don't need to break.
It's also very important that you slow down and get the right speed for the bend before(!) it begins. Applying the brakes in the curve, like you can do with a car easily if you are too fast, might be very critical and is normally "too late!". But you will certainly know it from the interstates exits.
Certainly modern hydraulic breaking systems like the Outlook has do not overhead so fast. But anyway, it's better when the vehicle is "hold by the gearbox" and you don't need to break always. So you have enough breaking power before the next hairpin or for an emergency stop.
Enjoy your trip!
