 A recommended tongue
weight or kingpin weight var-
ies in accordance with the
types of trailers or towing as
described below.
 To ensure the recommended
values shown below, the
trailer must be loaded by
referring to the following
instructions.
1.Conventional Towing
The gross trailer weight should
be distributed so that the tongue
weight is 9% to 11%. (Tongue
Weight/Gross trailer weight x
100 = 9% to 11%)
Gross trailer weight
Tongue Weight
If using a weight d istributing hitch
when towing, return the front axle to
the same weight as before the
trailer connection.
If front axle weight cannot be mea-
sured directly, measure the front
fender height above the front axle
before connection. Adjust weight
distributing hitch torque until front fender is returned to the same
height as before connection.
Do not reduce front fender height
below original measurement.
The gross trailer weight, gross axle
weight and tongue weight can be
measured with platform scales
found at a highway weighing sta-
tion, building supply company,
trucking company, junk yard, etc.
2.Fifth wheel Towing or Goose-
neck Towing
The gross trailer weight should
be distributed so that the kingpin
weight is 14% to 16%. (Kingpin
weight/Gross trailer weight x
100 = 14% to 16%)
Gross trailer weight
Kingpin weight
The gross trailer weight and kingpin
weight can be measured with plat-
form scales found at a highway
weighing station, building supply
company, trucking company, junk
yard, etc.

Trailer hitch assemblies have
different weight capacities. Toy-
ota recommends the use of Toy-
ota hitch/bracket for your
vehicle. For details, contact your
Toyota dealer.
If you wish to install a trailer
hitch, contact your Toyota
dealer.
 Use only a hitch that con-
forms to the gross trailer
weight requirement of your
vehicle.
 Follow the directions supplied
by the hitch manufacturer.
 Lubricate the hitch ball and
kingpin with a light coating of
grease.
 Remove the hitch ball when-
ever you are not towing a
trailer. Remove the trailer
hitch if you do not need it.
After removing the hitch, seal any mounting holes in the
vehicle body to prevent entry
of any substances into the
vehicle.
Use the correct trailer ball for
your application.
NOTICE
■When towing a fifth wheel
trailer
Be careful not to hit the cabin or
bed with the trailer while making a
sharp turn.
Hitch
WARNING
■Hitch
Trailer hitch assemblies have dif-
ferent weight capacities estab-
lished by the hitch manufacturer.
Even though the vehicle may be
physically capable of towing a
higher weight, the operator must
determine 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.
NOTICE
■When installing a trailer hitch
Use only the position recom-
mended by your Toyota dealer.
Do not install the trailer hitch on
the bumper; this may cause body
damage.

■If trailer sway occurs
One or more factors (crosswinds,
passing vehicles, rough roads, etc.)
can adversely affect handling of
your vehicle and trailer, causing
instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead. Do not try to
control trailer swaying by turning
the steering wheel.
• Begin releasing the accelerator
pedal immediately but very gradu-
ally to reduce speed. Do not
increase speed. Do not apply
vehicle brakes.
If you make no ext reme correction
with the steering or brakes, your
vehicle and trailer should stabilize.
(if enabled, Trailer Sway Control can
also help to stabilize the vehicle and
trailer.)
●After the trailer swaying has
stopped:
• Stop in a safe place. Get all occu-
pants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer. Make sure the load has not shifted.
Make sure the tongue weight is
appropriate, if possible.
• Check the load in the vehicle. Make sure the vehicle is not over-
loaded after occupants get in.
If you cannot find any problems, the
speed at which trailer swaying
occurred is beyond the limit of your
particular vehicle- trailer combina-
tion. Drive at a lower speed to pre-
vent instability. Remember that
swaying of the towing vehicle-trailer
increases as speed increases.
Dinghy towing
Your vehicle is not designed
to be dinghy towed (with 4
wheels on the ground)
behind a motor home.
NOTICE
■To avoid serious damage to
your vehicle
Do not tow your vehicle with the
four wheels on the ground.
