Hitch
Trailer hitch assemblies have different weight capacities.
Toyota recommends the use of Toyota hitch/bracket for your vehicle. For details, contact your Toyota dealer.
After removing the hitch, seal any mounting holes in the vehicle body to prevent entry of any substances into the vehicle.
WARNING

Trailer hitch assemblies have different weight capacities established by the hitch manufacturer.
Even though the vehicle may be physically capable of towing a higher weight, the operator must determine the maximum weight rating of the particular hitch assembly and never exceed the maximum weight rating specified for the trailer-hitch. Exceeding the maximum weight rating set by the trailer-hitch manufacturer can cause an accident resulting in death or serious personal injuries.
NOTICE
