& Connecting a trailer
! Trailer brakes WARNING
S08AL04
S08AL0401
. Adequate size trailer brakes are required when the trailer and its cargo exceed 1,000 lbs ( 453 kg ) total weight .
. 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 .
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 .
! 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 .
