I own a 2023 Chevy Blazer 2LT front-wheel drive with the v92 tow package but the only thing I don't have is the tow haul icon on my round selector.I only have three icons to choose from and that's highway snow mode and sport mode does the 2023 Blazer recognize when I'm towing automatically because I have no way to select it. On my gear shifter I do have a plus and minus buttons which allow me to select my gears manually do I do that while towing and if so what gear would I be in thank you in advance

 

If you have the tow feature, it's a button in the end of your gear select lever

 

Are you talking about the round selector below my gear shifter if so i only have 3 icons and none of them have the tow/haul icon just the highway, snow and sport icons are on my selector. My rpo sticker shows i have the v92 package i have a hitch and power connector as well

 

Looks like it's controlled from this dial (if equipped. Optional equipment)
Also page 206 in the owner's manual.
2LT appears to be a lower trim level.
Anyway you can simulate tow haul mode by manually selecting gears, and shifting a little later than usual. Also avoid using higher gears and overdrive.
