Trailer hitch assemblies have different weight capacities. Toyota recommends the use of Toyota hitch/bracket for your vehicle. For details, contact your Toyota dealer.
• If you wish to install a trailer hitch, contact your Toyota dealer.
• Use only a hitch that conforms to the gross trailer weight requirement of your vehicle.
• Follow the directions supplied by the hitch manufacturer.
• Lubricate the hitch ball with a light coating of grease.
• Remove the trailer hitch whenever you are not towing a trailer.
After removing the hitch, seal any mounting hole in the vehicle body to prevent entry of any substances into the vehicle.
