Here's the full text from my 2018 manual, so people see the exact and complete wording GM uses:
Tow/Haul is designed to be most effective when the vehicle and trailer combined weight is at least 75% of the vehicle's Gross Combined Weight Rating (GCWR). See “Weight of the Trailer” under Trailer Towing 0 296. Tow/Haul is most useful under the following driving conditions:
. When pulling a heavy trailer or a large or heavy load through rolling terrain.
. When pulling a heavy trailer or a large or heavy load in stop-and-go traffic.
. When pulling a heavy trailer or a large or heavy load in busy parking lots where improved low speed control of the vehicle is desired.
Operating the vehicle in Tow/Haul when lightly loaded or with no trailer at all will not cause damage. However, there is no benefit to the 318 Driving and Operating selection of Tow/Haul when the vehicle is unloaded. Such a selection when unloaded may result in unpleasant engine and transmission driving characteristics and reduced fuel economy. Tow/Haul is recommended only when pulling a heavy trailer or a large or heavy load.
I'm at 70% of my GCWR but with 15000 lbs of trailer, I use tow/haul.
