Trailer tongue load
● A recommended tongue load varies in accordance with the types
of trailers or towing as described below.
● In order to ensure the recommended values shown below, the
trailer must be loaded by referring to the following instructions.
The trailer cargo load should be di stributed so that the tongue load
is 9 to 11% of the gross trailer weight, not exceeding the following.
2.7 L 4-cylinder (1AR-FE) engine
Without towing package: 150 lb. (68 kg)
With towing package: 350 lb. (150 kg)
3.5 L V6 (2GR-FE) engine
Without towing package: 200 lb. (90 kg)
With towing package: 500 lb. (200 kg)
(Tongue load / Gross trailer weight x 100 = 9 to 11%)
If the gross trailer weight is over 2000 lbs. (900 kg), it is necessary
to use a sway control device with sufficient capacity.
The gross trailer weight and tongue l oad can be measured with plat-
form scales found at a highway weighing station, building supply
company, trucking company, junk yard, etc.

HitchTrailer hitch assemblies have diff erent weight capacities established
by the hitch manufacturer. Even th ough the vehicle may be rated for
towing a higher weight, the operator must never exceed the maxi-
mum weight rating specified for the trailer hitch.
Trailer towing tips
Your vehicle will handle differently when towing a trailer. The 3 main
causes of vehicle-trailer accident s are driver error, excessive speed
and improper trailer loading. Keep the following in mind when towing.
● Before starting out, check the trailer lights and the vehicle-trailer
connections. Recheck after driving a short distance.
● Practice turning, stopping and reversing with the trailer attached in
an area away from traffic until you become accustomed to the feel
of the vehicle.
● 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 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 increased. For each 10 mph (16 km/h)
of speed, allow at least o ne vehicle and trailer length.
● Avoid sudden braking as you may skid, resulting in jackknifing and
loss of 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 mak-
ing turns.

When driving
●
Note that when making a turn, th e trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a larger than normal turning radius.
● Crosswinds and rough roads will adversely affect handling of your
vehicle and trailer, causing sway . Periodically check the rear to
prepare for being passed by large trucks or buses, which may
cause your vehicle and trailer to sway. If swaying occurs, firmly grip
the steering wheel, reduce speed immediately but gradually, and
steer straight ahead. Never increase speed. If you make no
extreme correction with the stee ring or brakes, your vehicle and
trailer will stabilize.
● Take care when passing other vehi cles. Passing requires consider-
able distance. After pass ing a vehicle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
● 2.7 L 4-cylinder (1AR-FE) engine: In order to maintain engine brak-
ing efficiency when driving on a long steep downgrade, do not use
overdrive. Transmission shift r ange position must be in 5 in S
mode.
● 3.5 L V6 (2GR-FE) engine: In order to maintain engine braking effi-
ciency when driving on a long st eep downgrade, do not use over-
drive. Transmission shift range position must be in 4 in S mode.
● Due to the added load of the trailer, your vehicle's engine may
overheat on hot days (at temperatures over 85°F [30°C]) when
driving up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immedi ately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.
( → P. 545)

248 2-5. Driving information
●Always place wheel blocks under both the vehicle and the trailer
wheels when parking. Apply the parking 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 bloc ks under both the vehicle and
trailer wheels.
When the wheel blocks are in place, 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 the P position, start the engine. Be
sure to keep the brake pedal pressed.
Shift into 3, 2, 1, or the R position (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.

Before towing
Check that the following conditions are met:
●The vehicle's tires are properly inflated. ( →P. 562)
● Trailer tires are inflated according to the trailer manufacturer's recom-
mendation.
● All trailer lights work.
● All lights work each time you connect them.
● The vehicle remains level when a loaded or unloaded trailer is hitched.
Do not drive if the vehicle is not level, and check for improper tongue
load, overloading, worn suspension, or other possible causes.
● The trailer cargo is securely loaded.
● The rear view mirrors conform to a ll applicable federal, state/provincial or
local regulations. If they do not, install rear view mirrors appropriate for
towing purposes.
■ Break-in schedule
If your vehicle is new or equipped with any new power train components
(such as an engine, transmission, differential and wheel bearing), Toyota
recommends that you do not tow a trailer until it has been driven for over
2000 miles (3200 km).
However, avoid full throttle acceleration.
■ Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance
due to the additional load. (See “Scheduled Maintenance Guide” or
“Owner’s Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approxi-
mately 600 miles (1000 km) of trailer towing.

250 2-5. Driving information
CAUTION
■Trailer towing precautions
●Follow all the instructions described in this section. Failure to do so could
cause an accident resulting in death or serious injury.
● Exceeding the towing capacity, GVWR or GAWR can cause an accident
resulting in death or serious personal injuries.
■ To avoid accident or injury
●Do not exceed 45 mph (72 km/h) or the posted towing speed limit, which-
ever is lower. As instability (swaying) of the towing vehicle-trailer combina-
tion increases as speed increases, exceeding 45 mph (72 km/h) may
cause loss of control.
● Do not exceed the trailer hitch assembly weight, gross vehicle weight,
gross axle weight and trailer tongue load capacities.
● Never load more weight in the back than in the front of the trailer. About
60% of the load should be in the front half of the trailer, and the remaining
40% in the rear.
● Do not use cruise control when you are towing.
● Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts.
● 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 the vehicle with the compact spare tire installed.
■ Hitches
●If you wish to install a trailer hitch, contact your Toyota dealer.
● Use only a hitch that conforms to the gross trailer weight requirement.
● 2.7 L 4-cylinder (1AR-FE) engine: The towing capacity of 3500 lb. (1500
kg) can only be guaranteed when using a genuine Toyota hitch assembly
or equivalent.
● 3.5 L V6 (2GR-FE) engine: The towing capacity of 5000 lb. (2000 kg) can
only be guaranteed when using a genuine Toyota hitch assembly or equiv-
alent.
● Follow the directions supplied by the hitch manufacturer.

When driving
CAUTION
●
Lubricate the hitch ball with a light coat 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 substances into the vehicle.
■ When towing a trailer
●If the gross trailer weight exceeds 1000 lb. (453 kg), trailer brakes are
required. Toyota recommends trailers with brakes that conform to all appli-
cable federal and state/provincial regulations.
● Never tap into your vehicle's hydraulic system, as this will lower the vehi-
cle's braking effectiveness.
● Never tow a trailer without using a safety chain securely attached to both
the trailer and the vehicle. If damage occurs to the coupling unit or hitch
ball, there is danger of the trailer wandering into another lane.
NOTICE
■When installing a trailer hitch
●Use only the position recommended by your Toyota dealer. Do not install
the trailer hitch on the bumper as this may cause body damage.
● Do not use axle-mounted hitches, as they can cause damage to the axle
housing, wheel bearings, wheels or tires.
■ Safety chain
A safety chain must always be used between the towing vehicle and the
trailer. Leave sufficient slack in the chain for turns. The chain should cross
under the trailer tongue to prevent the tongue from dropping to the ground in
the case that it becomes damaged or separated. For the correct safety chain
installation procedure, ask your Toyota dealer.
■ Do not directly splice trailer lights
Directly splicing trailer lights may damage your vehicle's electrical system
and cause a malfunction.

Maintenance and care
Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new tire pressure warning valve and transmitter ID codes
must be registered in the tire pre ssure warning computer and the tire
pressure warning system must be initialized. Have tire pressure
warning valve and transmitter ID codes registered by your Toyota
dealer. ( →P. 457)
Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized when the
tire inflation pressure is changed (such as when changing
traveling speed or towing a trailer.)
When the tire pressure warning syst em is initialized, the current tire
inflation pressure is set as the benchmark pressure.
■ How to initialize the tire pressure warning system
Park the vehicle in safe place and turn the “ENGINE START
STOP” switch or the engine switch OFF.
While the vehicle is moving, in itialization is not performed.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. ( →P. 562)
Make sure to adjust the tire pressure to the specified cold tire
inflation pressure level. The tire pressure warning system will
operate based on this pressure level.
Turn the “ENGINE START STOP” switch to IGNITION ON
mode (vehicles with smart key sy stem) or the engine switch to
the “ON” position (vehicles without smart key system).
