You can go to 100% of the ratings. The engineers aren't going to allow more than it can handle. The problem is the "tow rating" is typically NOT the limiting factor.
I pulled up the current version of your car and it has a max hitch weight of 350lb. Ideally, you would like around 15% of the trailer resting on the hitch. That gives you 2300lb for the trailer (12% would be 2900lb).
Also, on the door should have a yellow sticker that lists the payload. Payload includes people, gear, any bolt on items and the hitch weight. The current model has around 1200lb payload. A family of 4 can easily eat up 500-600lb. If you pack the back with gear, it's easy to get overloaded.
As far as trailers, look at GVWR (Gross Vehicle Weight Rating), there will be a sticker, usually near the front driver side. Start with this as your assumed wet weight and assume 15% of the GVWR is on the hitch.
As mentioned a pop-up trailer is probably your best bet.
While they have marketed it as an SUV, it's really station wagon. If you want to tow something more substantial, move up to a body on frame truck, which is much better suited.
