Cadillac SRX

I have a 2012 SRX and it is automatic and 4 wheel down towable. I just bought it 2 months ago because it is. Not sure why the 2014 isn't though, unless they changed the transmission or something else! right in the owner maual says on mine to pull shifter cover up, then push down plastic button in upper rh corner down and shift into neutral. Thats it, then when you are done towing, put in park and run for 5 minutes or so.
