I found several references to it in the manual in the sections involving changing the wheels and tires. Page 328 in 2016 manual. Likely in a similar location in 2017. But it's the same as Gen 1 100 pound-feet

Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification. See Capacities and Specifications
0 328 for the wheel nut torque specification.
At least the OP tried looking in the owner's manual :) I like using the PDF version. Very easy to search.
Yeah didn't check in the specs section. Other cars have it listed in the wheel tire section.

FYI, I have a torque wrench. After an incident 2 years ago with a GM dealer, I don't trust them anymore and check afterwards.
Heck, I trust no one to torque it correctly. But yes, at least verify. They all love the impact wrenches and I have found over-torquing in more than one case. Tire shops or dealers, it depends on the person doing the work.

Another reason I do my own: I carefully inspect the tires and also dig out any rock, pebbles, etc in the treads. I have found more than one metal object slowly worming it's way into the tread during the close inspection. I doubt anyone else spends the time doing that.
The eternal question lubricate threads or not ?
Never, ever lubricate the lug nut bolt or nut threads. This will lead to over-torquing and there is no need for it. I rotate my own wheels every 7500 miles and have never had an issue removing the lug nuts. If you try to under-torque, you basically are guessing.

I have had the aluminum wheels seize to the steel hubs due to galvanic action, but never the lug nuts. So use the anti-seize (very lightly) where the back of the wheel mates to the steel hub, but not the lug nuts.
