Subaru Legacy BN/BS (2015-2019) Owners Manual: Trailer towing (Outback)

Your vehicle is designed and intended to be used primarily as a passenger-carrying vehicle. Towing a trailer puts additional loads on your vehicle's engine, drivetrain, brakes, tires and suspension and has an adverse effect on fuel economy and air conditioning system cooling performance.

If you do decide to tow a trailer, your safety and satisfaction depend upon proper use of correct equipment and cautious operation of your vehicle. Seek the advice of your SUBARU dealer to assist you in purchasing a hitch and other necessary towing equipment appropriate for your vehicle. Do not use towing equipment other than genuine SUBARU towing equipment. In addition, be sure to follow the instructions on correct installation and use provided by SUBARU.

SUBARU assumes no responsibility for injuries or vehicle damage that result from trailer towing equipment, or from any errors or omissions in the instructions accompanying such equipment or for your failure to follow the proper instructions.

Regularly check that the hitch mounting bolts and nuts are tightened securely.
