Trailer hitch assemblies have different
weight capacities. Lexus recommends
the use of Lexus hitch/bracket for your
vehicle. For details, contact your Lexus
dealer.
If you wish to install a trailer hitch,
contact your Lexus 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 hitch ball whenever you
are not towing a trailer. Remove the
trailer hitch if you do not need it.
After removing the hitch, seal any
mounting hole in the vehicle body to
prevent entry of any substances into
the vehicle.
Use the correct trailer ball for your
application.

■ 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.
