■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.
■ 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.

WARNING
■Trailer towing precautions
To tow a trailer safely, use extreme care and drive the vehicle in accordance
with the trailer’s characteristics and operating conditions. Failure to do so
could cause an accident resulting in death or serious injury. V ehicle stability
and braking performance are affected by trailer stability, brak e setting and
performance, and the hitch. Your vehicle will handle differentl y when towing
a trailer.
■ To avoid accident or injury
● Do not exceed the TWR, unbraked TWR, GCWR, GVWR or GAWR.
● If the gross trailer weight is over 2000 lb. (907 kg), a sway control device
with sufficient capacity is required.
● If the gross trailer weight is over 5000 lb. (2268 kg), a weigh t distributing
hitch with sufficient capacity is required.
● Adjust the tongue weight within the appropriate range. Place he avier loads
as close to the trailer axle as possible.
● Do not exceed 65 mph (104 km/h), the posted towing speed limit or the
speed limit for your trailer as set forth in your trailer owner ’s manual,
whichever is lowest. Slow down sufficiently before making a turn, in cross-
winds, on wet or slippery surface, etc., to help avoid an accident. If you
experience a vehicle-trailer instability from reducing a certai n speed, slow
down and make sure you keep your vehicle speed under the speed of
which you experience the instability.
● Do not make jerky, abrupt or sharp turns.
● Do not apply the brakes suddenly as you may skid, resulting in jackknifing
and loss of vehicle control. This is especially true on wet or slippery sur-
faces.
● Do not exceed the trailer hitch assembly weight, gross vehicle weight,
gross axle weight and trailer tongue weight capacities.
● Do not use cruise control when towing.
● Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts while descending steep or long
downhill grades.
● Vehicle-trailer instability is more likely on steep long downhi lls. Before
descending steep or long downhill grades, slow down and downshi ft. Do
not make sudden downshifts when descending steep or long downhi ll
grades. Avoid holding the brake pedal down too long or applying the
brakes too frequently. This could cause the brakes to overheat and result
in reduced braking efficiency.
● Do not tow a trailer when the temporary spare tire is installed on your vehi-
cle.

WARNING
■Hitch
Trailer hitch assemblies have different 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 ma ximum
weight rating specified for the trailer-hitch. Exceeding the ma ximum weight
rating set by the trailer-hitch manufacturer can cause an accid ent resulting
in death or serious personal injuries.
■ When towing a trailer
Toyota recommends trailers with brakes that conform to any appl icable fed-
eral and state/provincial regulations.
● If the gross trailer weight exceeds unbraked TWR, trailer brake s are
required. Toyota recommends trailers with brakes that conform t o all appli-
cable federal and state/provincial regulations.
● Never tap into your vehicle’s hydraulic system, as this will lo wer the vehi-
cle’s braking effectiveness.
● Never tow a trailer without using a safety chain securely attac hed to both
the trailer and the vehicle. If damage occurs to the coupling u nit or hitch
ball, there is danger of the trailer wandering into another lan e.
NOTICE
■When installing a trailer hitch
Use only the position recommended by your Toyota dealer. Do not install
the trailer hitch on the bumper; this may cause body damage.
■ Do not directly splice trailer lights
Do not directly splice trailer lights. Directly splicing traile r lights may damage
your vehicle’s electrical system and cause a malfunction.
■ When towing a fifth wheel trailer
Be careful not to hit the cabin or bed with
the trailer while making a sharp turn.

1944-1. Before driving
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.
