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.
