We have a 2012 Luxury package SRX, the manual states that the tow capacity is 25oolbs unless you have the tow package which increases the weight to 3500lbs. Here is where I am alittle confused. what constitutes the tow package, because cadillac couldnt even tell me if we had the tow package or not. I checked and found that the wire harness is there at the bumper, behind the facial plate. Does this mean that I have the tow package? Cadillac wanted over $400 bucks to install that wiring before I knew that it was already there. Reason for asking is, I am having a tow hitch installed(not by Cadillac) this week and I am looking to pull a 17ft boat that weighs approximately 2300lbs with the trailer.
