Towing related terms
Towing related termMeaning
GVWR (Gross Vehicle Weight
Rating) The maximum allowable gross vehicle
weight. The gross vehicle weight is the
total weight of the vehicle. When towing
a trailer, it is the sum of the vehicle
weight (including the occupants, cargo
and any optional equipment installed on
the vehicle) and the tongue load.
GAWR (Gross Axle Weight
Rating) The maximum allowable gross axle
weight. The gross axle weight is the
load placed on each axle (front and
rear).
GCWR (Gross Combination
Weight Rating) The maximum allowable gross combi-
nation weight. The gross combination
weight is the sum of the total vehicle
weight (including the occupants, cargo
and any optional equipment installed on
the vehicle) and the weight of the trailer
being towed (including the cargo in the
trailer).
Gross trailer weight The sum of the trailer weight and the
weight of the cargo in the trailer.
Towing capacity The maximum allowable gross trailer
weight. Towing capacity is calculated
considering the base vehicle with nec-
essary vehicle equipment and occu-
pants. Additional optional equipment,
passengers and cargo in the vehicle will
reduce the towing capacity, gross trailer
weight include the trailer, cargo and
necessary equipment for towing.
Tongue load The load placed on the trailer hitch ball

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 (2TR-FE) engine
200 lb. (90.7 kg)
4.0 L V6 (1GR-FE) engine
500 lb. (227 kg)
(Tongue load / Gross trailer weight  100 = 9 to 11%)
If the gross trailer weight is over 2000 lbs. (907 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.

Hitch and tow hitch receiver■ Hitch
Trailer hitch assemblies have different weight capacities estab-
lished by the hitch manufacturer . Even though the vehicle may be
rated for towing a higher weight, the operator must never exceed
the maximum weight rating specified for the trailer hitch.
■ Tow hitch receiver (if equipped)
A tow hitch receiver installed
under the rear bumper is rated
for weight that does not exceed
the vehicle's total towing weight.

Selecting a trailer ball
Use the correct trailer ball for your application. Trailer ball load rating
Matches or exceeds the gross
trailer weight rating of the trailer.
Ball diameter
Matches the size of the trailer
coupler. Most couplers are
stamped with the required trailer
ball size.
Shank length
Protrudes beyond the bottom of
the lock washer and nut at least 2
threads.
Shank diameter
Matches the ball mount hole
diameter size.
Connecting trailer lights
Use the wire harness stored in
the rear end under body.

Trailer towing tipsYour vehicle will handle differently w hen towing a trailer. In order to
avoid accident, death or serious in jury, 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.

●
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 vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
● In order to maintain engine braking efficiency when driving on a
long steep downgrade, do not use overdrive. Transmission shift
range position must be in 3 (standard type), or “4”, in the S mode
(multi-mode type).
● 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.

4RUNNER_U●
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 P, start the engine. Be sure to keep
the brake pedal pressed.
Shift into D or R (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.
● 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 trailer ball is set up at the proper height for the coupler on the t\
railer.
● 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, 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 500
miles (800 km).
However, avoid full throttle acceleration.
Your vehicle is equipped with a service
connector for the trailer brake controller
as shown.

■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, GCWR and 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.
● Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts.
● 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.
● 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.
