Have you asked your dealer for the list of things added in the tow pkg?
Very likely you can add it all.
But I doubt that the 4 cylinder tows a lot, so it depends what you want to tow.
If you are talking aluminum fishing boat, jet ski, garbage trailer for dump runs, then it should be easy.
Saw in another thread you want to add a lift kit, and possibly bigger diameter tires. If you want to tow much, possibly reconsider those choices. The bigger tires, and a lift, adversely affect your towing.
