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 350 lb. (158
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 different weight capacities established
by the hitch manufacturer. Even th ough the vehicle may be rated for
towing a higher weight, the operat or 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 accidents 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 reve rsing 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 trailer 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 especiall y 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.

Before towing
Check that the following conditions are met:
●The vehicle's tires are properly inflated. ( P. 539)
● 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 all applicable federal, state/provincial or
local regulations. If they do not, instal l 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 500
miles (800 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.

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.
● The towing capacity of 3500 lb. (1500 kg) can only be guaranteed when
using a genuine Toyota hitch assembly or equivalent.
● Follow the directions supplied by the hitch manufacturer.
● 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.

CAUTION
■
When towing a trailer
●If the gross trailer weight exceeds 1000 lb. (453 kg), trailer brakes are
required. Toyota recommends trailers wi th 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; 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.
