Need a bit of 'educating'...
Need advice on when/where to use 'tow/haul'. Use only when ascending/descending hilly areas? Keep it off when on flat roadways? Exactly what does it do i.e. does it restrict the transmission from it's...

Tow/haul causes the trans to stay in lower gears longer under a load so as to keep the RPMs up where the engine develops more power. Perfectly OK to leave it on and let the computers determine when to shift better than you might though MPG might go down a tiny amount. Also OK to turn off and on if you wish. If you leave it on all the time the trans might never shift into the highest gear but that's OK too if the engine is laboring.
