●Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before maki ng
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.
● Slow down before making a turn, in cross winds, on wet or slipp ery
surfaces, etc.
Increasing vehicle speed can destabilize the trailer.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the lengt h of
your trailer, and be sure you have plenty of room before changi ng
lanes.
● To maintain engine braking efficiency and charging system perfo r-
mance when using engine braking, do not put the transmission in
D.
● Instability happens more frequently when descending steep or lo ng
downhill grades. Before descending, slow down and downshift. Do
not make sudden downshifts while descending steep or long down-
hill grades.
● Avoid holding the brake pedal down too long or applying the bra kes
too frequently. This could cause the brakes to overheat and result in
reduced braking efficiency.
● Due to the added load of the trailer, your vehicle’s engine may over-
heat on hot days (at temperatures over 85°F [30°C]) when drivin g
up a long or steep grade. If the engine coolant temperature gau ge
indicates overheating, immediately turn off the air conditionin g (if in
use), pull your vehicle off the road and stop in a safe spot.

●Always place wheel blocks under both the vehicle’s and the trai ler’s
wheels when parking. Apply the parking brake firmly, and put th e
transmission in P. Avoid parking on a slope, but if unavoidable , do
so only after perform ing 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 afte r parking on a slope:
With the transmission in P, start the engine. Be sure to keep t he
brake pedal pressed.
Shift into a forward gear. If reversing, shift into R.
Release the parking brake and brake pedal, and slowly pull or
back away from the wheel bloc ks. Stop and apply the brakes.
Have someone retrieve the blocks.

No matter which class of tow hitch
applies, for a more safe trailer hookup,
the trailer ball setup must be the proper

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 w heel.
• 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 combination.
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, brake setting and
performance, and the hitch. Your vehicle will handle differently 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.
● Adjust the tongue weight within the appropriate range. Place heavier 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 tur n, 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 downhil l
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 downshift. 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.

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 maximum
weight rating specified for the trailer-hitch. Exceeding the maximum 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 applicable fed-
eral and state/provincial regulations.
● If the gross trailer weight exceeds unbraked TWR, trailer brakes 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.
