●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.

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.

The rear bumper of your vehicle is
equipped with a hole to install a
trailer ball. If you have any ques-
tions, contact your Toyota dealer.
The gross trailer weight (trailer
weight plus cargo weight) when
towing with the bumper must never
exceed the TWR (P. 162) or
5000 lb. (2268 kg) whichever is
lower.
Use the correct trailer ball for your application.
Trailer ball load rating
Matches or exceeds the gross
trailer weight rating of the trailer.
Ball diameter
Matches the size of the trailer cou-
pler. Most couplers are stamped
with the required trailer ball size.
Shank length
Protrudes beyond the bottom of the lock washer and nut by at least 2
threads.
Shank diameter
Matches the ball mount hole diameter size.

Your vehicle will handle differently when towing a trailer. Help to avoid
an accident, death or serious injury, keep the following in mind when
towing:
● Speed limits for towing a trailer vary by state or province. Do not
exceed the posted to wing speed limit.
● Toyota recommends that the vehicle-trailer speed limit is 65 mph
(104 km/h) on a flat, straight, dry road. Do not exceed this limit, the
posted towing speed limit or the spe ed limit for your trailer as set
forth in your trailer owner’s manual,  whichever is lowest. Instability
of the towing vehicle-trailer combination (trailer sway) increases as
speed increases. Exceeding speed limits may cause loss of control.
● Before starting out, check the trailer lights, tires and the vehicle-
trailer connections. Recheck after driving a short distance.
● Practice turning, stopping and reve rsing with the trailer attached in
an area away from traffic until  you become accustomed to the feel
of the vehicle-trailer combination.
● Reversing with a trailer attached is difficult and requires practice.
Grip the bottom of the steering  wheel and move your hand to the
left to move the traile r to the left. Move your hand to the right to
move the trailer to the right. (This is generally opposite to reversing
without a trailer attached.) Avoid sharp or prolonged turning. Have
someone guide you when reversing to  reduce the risk of an acci-
dent.
● As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increa sed. For each 10 mph (16 km/h)
of speed, allow at least one vehicle and trailer length.

●Always place wheel blocks under both the vehicle’s and the trailer’s
wheels when parking. Apply the pa rking brake firmly, and put the
transmission in P. Avoid parking on a slope, but if unavoidable, do
so only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks  under both the vehicle’s and
trailer’s wheels.
When the wheel blocks are in pl ace, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into P and turn off the engine.
● When restarting after parking on a slope:
With the transmission in P, start the engine. Be sure to keep the
brake pedal pressed.
Shift into D or R (if reversing).
Release the parking brake and brake pedal, and slowly pull or
back away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.
■Matching trailer ball height  to trailer coupler height
No matter which class of tow hitch
applies, for a more safe trailer hookup,
the trailer ball setup must be the proper
height for the coupler on the trailer.
