Hitches; Trailer Ball - Lexus RX300 2003 Owner's Manual

Hitches

D If you wish to install a trailer hitch, your Lexus dealer should
be consulted.
D Use only a hitch which is recommended by Lexus dealer
and conforms to the total trailer weight requirement.
D Follow the directions supplied by the hitch manufacturer.
Lubricate the hitch ball with a light coat of grease.
D Lexus recommends removing the trailer hitch whenever you
are not towing a trailer to reduce the possibility of additional
damage caused by the hitch if your vehicle is struck from
behind. After removing the hitch, seal any mounting holes
in the vehicle body to prevent entry of pollutants such as
exhaust fumes, dirt, water, etc.
NOTICE
D Install the trailer hitch using only the position
recommended by your Lexus dealer. Do not install
the trailer hitch on the bumper; this may cause body
damage.
D Do not use axle–mounted hitches as they can cause
damage to the axle housing, wheel bearings, wheels
or tires.
