S The trailer cargo load should be
distributed so that the tongue load
is 9 to 11% of the total trailer weight,
not exceeding the maximum158 kg
(350 lb.) for vehicles with towing kit
or 90 kg (200 lb.) for vehicles with-
out towing kit. Never load the trailer
with more weight in the back than
in the front. About 60% of the trailer
load should be in the front half of
the trailer and the remaining 40 % in
the rear.
HITCHES
S Use only a hitch with is recommended
by the hitch manufacturer and con-
forms to the total trailer weight require-
ment.
S Follow the directions supplied by the
hitch manufacturer. Lubricate the hitch
ball with a light coat of grease.
S Toyota recommends removing the
trailer hitch whenever you are not tow-
ing a trailer to reduce the possibilty 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 ex-
haust fumes, dirt, water, etc.
NOTICE
Do not use axle-mounted hitches as
they can cause damage to the axle
housing, wheel bearings, wheels or
tires. Also, never install a hitch
which may interfere with the normal
function of an Energy Absorbing
Bumper, if so equipped.
