●A recommended tongue weight or kingpin weight varies in accor-
dance with the types of trailer s or towing as described below.
● To ensure the recommended values shown below, the trailer must
be loaded by referring to t he following instructions.
• Tongue Weight The gross trailer weight should be distributed so that the tong ue
weight is 9% to 11%. (Tongue We ight/Gross trailer weight x 100
= 9% to 11%)

If using a weight distributing hi tch when towing, return the front
axle to the same weight as b efore 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 b efore connection.
The gross trailer weight, gross axle weight and tongue weight
can be measured with platform sca les found at a highway weigh-
ing station, building supply company, trucking company, junk
yard, etc.

Trailer hitch assemblies have different weight capacities. Toyota rec-
ommends the use of Toy ota hitch/bracket for your vehicle. For d etails,
contact your Toyota dealer.
● If you wish to install a trailer hitch, contact your Toyota dea ler.
● Use only a hitch that conforms to the gross trailer weight requ ire-
ment of your vehicle.
● Follow the directions suppli ed by the hitch manufacturer.
● Lubricate the hitch ball and kingpin with a light coating of gr ease.
● Remove the hitch ball whenever you are not towing a trailer.
Remove the trailer hitch if you do not need it. After removing the
hitch, seal any mounting hole in the vehicle body to prevent en try of
any substances 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 yo ur Toyota dealer.
The gross trailer weight (trailer
weight plus cargo weight) when
towing with the bumper must never
exceed the TWR ( P. 187) or
3500 lb. (1590 kg) whichever is
lower.

Your vehicle will handle differently when towing a trailer. To help avoid
an accident, death or serious injury, keep the following in min d 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 vehicl e-trailer speed limit is 65 mph
(104 km/h) on a flat, straight, dry road. Do not exceed this li mit, the
posted towing speed limit or the speed limit for your trailer a s set
forth in your trailer owner’s manu al, whichever is lowest. Instability
of the towing vehicle-trailer combination (trailer sway) increa ses as
speed increases. Exceeding speed limits may cause loss of contr ol.
● Before starting out, check the trailer lights, tires and the vehicle-
trailer connections. Recheck af ter driving a short distance.
● Practice turning, stopping and reversing with the trailer attac hed in
an area away from traffic until you become accustomed to the fe el
of the vehicle-trailer combination.
● Reversing with a trailer attached is difficult and requires pra ctice.
Grip the bottom of the steering wheel and move your hand to the
left to move the trailer to the left. Move your hand to the rig ht to
move the trailer to the right. (This is generally opposite to r eversing
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, vehicl e-to-
vehicle distance should be increased. For each 10 mph (16 km/h)
of speed, allow at least one v ehicle and trailer length.
● Avoid sudden braking as you may skid, resulting in the trailer jack-
knifing and a loss of vehicle control. This is especially true on wet or
slippery surfaces.
● Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before maki ng
a turn.
● Note that when making a turn, the trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by mak ing
a wider than normal turning radius.
Trailer towing tips

1964-1. Before driving
■Matching trailer ball height to trailer coupler height
■ Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 551)
● Trailer tires are inflated according to the trailer manufacture r’s recommen-
dation.
● All trailer lights work as required by law.
● All lights work each time you connect them.
● The trailer ball is set at the proper height for the coupler on the trailer.
● The trailer is level when it is hitched.
Do not drive if the trailer is not level, and check for imprope r tongue weight,
overloading, worn suspension, or other possible causes.
● The trailer cargo is securely loaded.
● The rear view mirrors conform to all applicable federal, state/provincial or
local regulations. If they do not, install rear view mirrors ap propriate for tow-
ing purposes.
● Depress power mode button (vehicles with an automatic transmiss ion).
( P. 212)
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.

■When towing a trailer
Disable the following systems, as the systems may not operate p roperly.
● LDA (Lane Departure Alert with Yaw Assist Function) (if equippe d)
( P. 258)
● Dynamic radar cruise control (if equipped) ( P. 266)
● Cruise control (if equipped) ( P. 280)
● BSM (Blind Spot Monitor) (if equipped) ( P. 292)
● Intuitive parking assist (if equipped) ( P. 284)
● RCTA (Rear Cross Traffic Alert) function (if equipped) ( P. 292)
■ Break-in schedule
If your vehicle is new or equipped with any new power train com ponents
(such as an engine, transmission, differential or wheel bearing ), Toyota rec-
ommends that you do not tow a trailer until the vehicle has bee n driven for
over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start
towing. However, for the next 500 miles (800 km), drive the veh icle at a speed
of less than 50 mph (80 km/h) when towing a trailer, and avoid full throttle
acceleration.
■ Maintenance
●If you tow a trailer, your vehicle will require more frequent m aintenance due
to the additional load. (See “Owner’s Warranty Information Book let” or
“Scheduled Maintenance Guide”/“Owner’s Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.

1984-1. Before driving
■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 gra dually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme 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 occupants 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 overloaded 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 combinat ion.
Drive at a lower speed to prevent instability. Remember that sw aying of the
towing vehicle-trailer increases as speed increases.
