Your vehicle is designed primarily as a
passenger −and− load− carrying vehicle. Tow-
ing a trailer will have an adverse effect on
handling, performance, braking, durability
and driving economy (fuel consumption,
etc.). Your safety and satisfaction depend
on the proper use of correct equipment
and cautious driving habits. For your safe-
ty and the safety of others, you must not
overload your vehicle or trailer. Ask your
local Toyota dealer for further details be-
fore towing.
We recommend you use a weight distribut-
ing hitch when towing to keep your ve-
hicle level with the ground.
NOTICE
When towing a trailer, be sure to con-
sult your Toyota dealer for further in-
formation on additional requirements
such as a towing kit, etc.
WEIGHT LIMITS
Before towing, make sure the total trail-
er weight, gross combination weight,
gross vehicle weight, gross axle weight
and trailer tongue load are all within
the limits.
The total trailer weight and tongue load
can be measured with platform scales
found at highway weighing stations, build-
ing supply companies, trucking companies,
junk yards, etc.
CAUTION
The maximum gross trailer weight
(trailer weight plus cargo weight)
must never exceed the following.

If towing a trailer and cargo weigh-
ing over 907 kg (2000 lb.), it is
necessary to use a sway control
device with sufficient capacity. The
combination of the gross trailer
weight added to the total weight of
the vehicle, occupants and vehicle
cargo must never exceed a total of
the following.
5VZFE engine
Twowheel drive models 4173 kg (9200 lb.)
Fourwheel drive models
4309 kg (9500 lb.)
2UZFE engine Without towing package 4536 kg (10000 lb.)
With towing package
5352 kg (11800 lb.)
Exceeding the maximum weight of
the trailer, the vehicle, or the ve-
hicle and trailer combination, can
cause an accident resulting in seri-
ous personal injuries.
Trailer hitch assemblies have differ-
ent weight capacities established by
the hitch manufacturer. Even though
the vehicle may be physically capa-
ble of towing a higher weight, the
operator must determine the maxi-
mum weight rating of the particular
hitch assembly and never exceed
the maximum weight rating speci-
fied for the trailerhitch. Exceeding
the maximum weight rating set by
the trailer hitch manufacturer can
cause an accident resulting in seri-
ous personal injuries.
The gross vehicle weight must not
exceed the Gross Vehicle Weight
Rating (GVWR) indicated on the
Certification Label. The gross ve-
hicle weight is the sum of weights
of the unloaded vehicle, driver, pas-
sengers, luggage, hitch and trailer
tongue load. It also includes the
weight of any special equipment
installed on your vehicle.
The load on either the front or rear
axle resulting from distribution of
the gross vehicle weight on both
axles must not exceed the Gross
Axle Weight Rating (GAWR) listed
on the Certification Label.

wheel trailer, the cargo load must
be distributed so that the tongue
load is 19 to 21% of the total trailer
weight. Never load the trailer with
more weight in the back than in the
front. About 60% of the trailer load
should be in the front half of the
trailer and the remaining 40% in the
rear.

HITCHES
If you wish to install a trailer hitch, you
should consult with your Toyota dealer.
Use only a hitch recommended by the
hitch manufacturer and the one which
conforms to the total trailer weight
requirement.
The hitch must be bolted securely to
the vehicle frame and installed accord-
ing to the hitch manufacturer ’s instruc-
tions.
The hitch ball and king pin should have
a light coat of grease.
Toyota recommends removing the trail-
er hitch whenever you are not towing
a trailer to reduce the possibility of
additional damage caused by the hitch
if your vehicle is struck from behind.
After removing the hitch, seal any
mounting holes in the vehicle body to
prevent entry of pollutants such as ex-
haust fumes, dirt, water, etc.
NOTICE
Do not use axlemounted hitches as
they can cause damage to the axle
housing, wheel bearings, wheels or
tires. Also, never install a hitch which
may interfere with the normal function
of an Energy Absorbing Bumper, if so
equipped.

TRAILER BALL
Follow these easy steps to properly deter-
mine the correct trailer ball for your ap-
plication:
1. Determine the correct trailer ball size for the trailer coupler. Most couplers
are stamped with the required trailer
ball size. The sizes you will most likely
find stamped on the coupler are:
Trailer class
Typical trailer ball size
IV2 5/16 in.
II and III2 in.
I1 7/8 in.
2. Select the appropriate trailer ball to match or exceed the gross trailer
weight rating of the trailer. The trailer
ball load rating should be printed on
the top of the ball.
3. When mounted in the ball mount, the threaded ball shank must protrude be-
yond the bottom of the lock washer
and nut at least 2 threads. The trailer
ball shank must be matched to the ball
mount hole diameter size.
NOTICE
Vehicles with 2UZFE engine (with
towing package)—Only use a ball
mount attachment specified for the
Toyota Tundra.
BUMPER TOWING
The rear bumper of your vehicle is
equipped with a hole to install a trailer
ball. The maximum gross trailer weight is
2268 kg (5000 lb.).
CAUTION
The maximum gross trailer weight
(trailer weight plus cargo weight)
when towing with the bumper must
never exceed 2268 kg (5000 lb.).

CAUTION
If the total trailer weight exceeds
453 kg (1000 lb.), trailer brakes are
required.
Never tap into your vehicle’s hy-
draulic system as it would lower its
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 over into another
lane.

SERVICE CONNECTOR FOR TOWING
BRAKE CONTROLLER (with towing
package)
Your vehicle is equipped with a service
connector for the trailer brake controller
as shown. Link the connector to the trailer
brake controller via the sub wire harness
stored in the glove box. The detailed ex-
planation of the sub wire harness circuit
is packed together with the sub wire har-
ness.
Be sure to position the trailer brake con-
troller where it does not prevent the driver
from operating the pedal.
Toyota recommends that the sub wire har-
ness be stored in the glove box when it
is not in use.
TIRES
Ensure that your vehicle’s tires are
properly inflated. See Section 7 −2 and
Section 8 for instructions.
The trailer tires should be inflated to
the pressure recommended by the trail-
er manufacturer in respect to the total
trailer weight.

2004 TUNDRA from Sep. ’03 Prod. (OM34426U)
CAUTION
Do not exceed 72 km/h (45 mph) or
the posted towing speed limit,
whichever is lower. Because insta-
bility (swaying) of a towing vehicle
trailer combination usually in-
creases as the speed increases, ex-
ceeding 72 km/h (45 mph) may
cause loss of control.
Slow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts.
Avoid holding the brake pedal down
too long or too frequently. This
could cause the brakes to overheat
and result in reduced braking effi-
ciency.
Improving fuel economy is easy—just take
it easy. It will help make your vehicle last
longer, too. Here are some specific tips
on how to save money on both fuel and
repairs:
Keep your tires inflated at the cor-
rect pressure. Underinflation causes
tire wear and wastes fuel. See Section
7 −2 for instructions.
Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causing
greater fuel consumption.
Avoid lengthy warmup idling. Once
the engine is running smoothly, begin
driving—but gently. Remember, howev-
er, that on cold winter days this may
take a little longer.
Always keep the automatic transmis-
sion overdrive switch turned on.
Driving with the overdrive switch off
will reduce the fuel economy. (For de-
tails, see “Automatic transmission” in
Section 1 −7.)
Accelerate slowly and smoothly.
Avoid jackrabbit starts. Get into high
gear as quickly as possible.
Avoid long engine idling. If you have
a long wait and you are not in traffic,
it is better to turn off the engine and
start again later.
Avoid engine lugging or overrev-
ving. Use a gear position suitable for
the road on which you are travelling.
Avoid continuous speeding up and
slowing down. Stop−and− go driving
wastes fuel.
Avoid unnecessary stopping and
braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or
take advantage of through streets to
avoid traffic lights. Keep a proper dis-
tance from other vehicles to avoid sud-
den braking. This will also reduce wear
on your brakes.
Avoid heavy traffic or traffic jams
whenever possible.
Do not rest your foot on the clutch
or brake pedal. This causes premature
wear, overheating and poor fuel econo-
my.
Maintain a moderate speed on high-
ways. The faster you drive, the greater
the fuel consumption. By reducing your
speed, you will cut down on fuel con-
sumption.
