WARNING
Hitches
■
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 deter-
mine 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.
