Driving tips CAUTION D Do not modify the vehicle exhaust system, brake system, or other systems when installing a hitch or other trailer towing equipment. D Do not use axle-mounted hitches as they can cause damage to the axle housing, wheel bearings, wheels or tires. B WAGON including OUTBACK SPORT The use of a genuine SUBARU trailer hitch is recommended. A genuine SUBARU hitch is available from your SUBARU dealer. If use of a non-genuine hitch is unavoidable, be sure the hitch is suited to your vehicle and trailer. Consult with a professional hitch supplier to assist you in choosing an appropriate hitch for your vehicle. Be sure to follow all of the hitch manufacturer's instructions for installation and use. Never use a hitch that mounts only to the rear bumper. The bumper is not designed to handle that type of load. For all types of hitches, regularly check that the hitch mounting bolts and nuts are tight. B SEDAN SUBARU does not offer accessory trailer hitches. Consult with a professional hitch supplier to assist you in choosing an appropriate hitch for your vehicle. Be sure to follow all of the hitch manufacturer's instructions for installation and use. Never use a hitch that mounts only to the rear bumper. The bumper is not designed to handle that type of load. Regularly check that the hitch mounting bolts and nuts are tight. J Connecting a trailer B Trailer brakes If your trailer's total weight (trailer weight plus its cargo weight) exceeds 1,000 lbs (453 kg), the trailer is required to be equipped with its own brake system. Electric brakes or surge brakes are recommended, and must be installed properly. Check that your trailer's brakes conform with Federal, state/ province and/or other applicable regulations. Your SUBARU's brake system is not designed to be tapped into the trailer's hydraulic brake system. Please ask your SUBARU dealer and professional trailer supplier for more information about the trailer's brake system. - CONTINUED - 8-33
