Trailer brakes WARNING s08al04 s08al0401 Do not directly connect your trailer’s hydraulic brake system to the hydraulic brake system in your vehicle. Direct connection would cause the vehicle’s brake performance to deteriorate and could lead to an accident. 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. ! Trailer safety chains WARNING s08al0402 Always use safety chains between your vehicle and the trailer. Towing trailer without safety chains could create a traffic safety hazard if the trailer separates from the hitch due to coupling damage or hitch ball damage. In case the trailer hitch connector or hitch ball should break or become disconnected, the trailer could get loose and create a traffic safety hazard. For safety, always connect the towing vehicle and trailer with trailer safety chains. Two chains should be used in total, one to the right side and the other to the left side trailer tongue. Pass the chains crossing each other under the trailer tongue to prevent the trailer from dropping onto the ground in case the trailer tongue should disconnect from the hitch ball. Allow sufficient slack in the chains taking tight turn situations into account; however, be careful not to let them drag on the ground. ! Side mirrors s08al0403 After hitching a trailer to your vehicle, check that the standard side mirrors provide a good rearward field of view without significant blind spots. If significant blind spots occur with the vehicle’s standard side mirrors, use towing mirrors that conform with Federal, state/province and/ or other applicable regulations. !
