●A recommended tongue weight or kingpin weight varies in accor-
dance 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 distributing hitch when towing, return the front
axle to the same weight as before the trailer connection.
If front axle weight cannot be measured 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 weigh-
ing station, building supply company, trucking company, junk
yard, etc.

2.Fifth wheel Towing or Gooseneck TowingThe gross trailer weight should be distributed so that the kingpin
weight is 19% to 21%. (Kingpin weight/Gross trailer weight x 100
= 19% to 21%)
Gross trailer weight
Kingpin weight
The gross trailer weight and kingpin weight can be measured
with platform scales found at a highway weighing station, build-
ing supply company, trucking company, junk yard, etc.
CrewMax models: Current fifth wheel trailer designs are not com-
patible with short bed.
Trailer hitch assemblies have different weight capacities. Toyota rec-
ommends the use of Toyota 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 conforms to the gross trailer weight require-
ment 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 trailer hitch whenever you are not towing a trailer. After
removing the hitch, seal any mounting hole in the vehicle body to
prevent entry of any subs tances into the vehicle.
