Hello all, I'm planning on a tow trip with a lightweight trailer and I see under my hood there is a module that is marked tow and drive. I can't find anything in my manual for my 2017 Equinox 2.4 l about using this. I'm assuming I should put it in the tow position. I've never told anything before and that switch has always been in the drive position. When I flip it onto the tow position I don't see any indicator lights on the dash. I know not to use eco mode when towing. Does anyone know what the function of this module is? I wish it was explained in the owner's manual
