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 axle- mounted hitches as
they can cause damage to the axlehousing, wheel bearings, wheels ortires. Also, never install a hitch which
may interfere with the normal functionof an Energy Absorbing Bumper, if soequipped.

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
III and IV2Ð5/16 in.
II2 in.
I1Ð7/8 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.
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.).
FIFTH WHEEL TRAILER
NOTICE
When towing a fifth wheel trailer, be
careful not to hit the cabin or deckby the trailer while making a sharpturn.

MATCHING TRAILER BALL HEIGHT TO
TRAILER COUPLER HEIGHT
No matter which class of tow hitch ap-
plies, for a safe trailer hookup, the trailer
ball setup on must be the proper height
for the coupler on the trailer.
BRAKES AND SAFETY CHAINS

Toyota recommends trailers with brakes
that conform to any applicable federal
and state/provincial regulations.

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
case it becomes damaged or sepa-
rated. For correct safety chain proce-
dures, follow the hitch or trailer
manufacturer 's recommendations.
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.
TIRES

Ensure that your vehicle's tires are
properly inflated. See Chapter 7- 2 for
instructions.

The trailer tires should be inflated to
the pressure recommended by the trail-
er manufacturer in respect to the total
trailer weight.

TRAILER LIGHTS

Your vehicle is equipped with a wire
harness stored in the rear end under
body. Some models are fitted with a
socket for trailer lights under the rear
bumper. Use either of them to connect
and operate the trailer lights. However,
the trailer lights must comply with fed-
eral, state/provincial and local regula-
tions. See your local recreational ve-
hicle dealer or rental agency for the
correct type of wiring and relays for
your trailer. Check for correct operation
of the turn signals and stop lights each
time you hitch up. Direct splicing may
damage your vehicle's electrical system
and cause a malfunction of your lights.BREAK- IN SCHEDULE

Toyota recommends that you do not
tow a trailer with a new vehicle or a
vehicle with any new power train com-
ponent (engine, transmission, differen-
tial, wheel bearings, etc.) for the first
800 km (500 miles) of driving.
MAINTENANCE

If you tow a trailer, your vehicle will
require more frequent maintenance due
to the additional load. For this informa-
tion, please refer to the scheduled
maintenance information in the Sched-
uled Maintenance Guideº or Owner 's
Manual Supplementº.

Retighten all fixing bolts of the towing
ball and bracket after approximately
1000 km (600 miles) of trailer driving.
PRE- TOWING SAFETY CHECK

Check that your vehicle remains level
when a loaded or unloaded trailer is
hitched. Do not drive if the vehicle has
an abnormal nose- up or nose- down
condition, and check for improper
tongue load, overload, worn suspension
or other possible causes.

Make sure the trailer cargo is securely
loaded so that it cannot shift.

Check that your rear view mirrors con-
form to any applicable federal, state/
provincial or local regulation. If not,
install the rear view mirrors required
for towing purposes.
TRAILER TOWING TIPS
When towing a trailer, your vehicle will
handle differently than when not tow-
ing. The three main causes of vehicle-
trailer accidents are driver error, exces-
sive speed and improper trailer loading.
Keep these in mind when towing:

Before starting out, check operation of
the lights and all vehicle- trailer connec-
tions. After driving a short distance,
stop and recheck the lights and con-
nections. Before actually towing a trail-
er, practice turning, stopping and back-
ing with a trailer in an area away from
traffic until you learn the feel.

Backing with a trailer 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 the right. (This pro-
cedure is generally opposite to that
when backing without a trailer). Also,
just turn the steering wheel a little at
a time, avoiding sharp or prolonged
turning. Have someone guide you when
backing to reduce the risk of an acci-
dent.

Because stopping distance may be in-
creased, vehicle- to- vehicle distance
should be increased when towing a
trailer. For each 16 km/h (10 mph) of
speed, allow at least one vehicle and
trailer length between you and the ve-
hicle ahead. 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 accelera-
tion. If your vehicle has a manual
transmission, prevent excessive clutch
slippage by keeping engine rpm low
and not racing the engine. Always start
out in first gear.

Avoid jerky steering and sharp turns.
The trailer could hit your vehicle in a
tight turn. Slow down before making a
turn to avoid the necessity of sudden
braking.

Remember that when making a turn,
the trailer wheels will be closer than
the vehicle wheels to the inside of the
turn. Therefore, compensate for this by
making a larger than normal turning
radius with your vehicle.

Crosswinds and rough roads will ad-
versely affect handling of your vehicle
and trailer, causing sway. Pay attention
to the rear from time to time to pre-
pare yourself for being passed by large
trucks or buses, which may cause your
vehicle and trailer to sway. If swaying
happens, firmly grip the steering wheel
and reduce speed immediately but
gradually. Never increase speed. Steer
straight ahead. If you make no extreme
correction with the steering or brakes,
the vehicle and trailer will stabilize.

Be careful when passing other ve-
hicles. Passing requires considerable
distance. After passing a vehicle, do
not forget the length of your trailer and
be sure you have plenty of room be-
fore changing lanes.

In order to maintain engine braking effi-
ciency, do not use fifth gear (manual
transmission) or overdrive (automatic
transmission).

Because of the added load of the trail-
er, your vehicle's engine may overheat
on hot days (at temperatures over
30
5C [85 5F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperature gauge indicates
overheating, immediately turn off the air
conditioning (if in use), pull off the road
and stop in a safe spot. Refer to If
your vehicle overheatsº in Part 4 of
this manual.

Always place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firmly.
Put the transmission in Pº (automatic)
or in first or reverse (manual). Avoid
parking on a slope with a trailer, but
if it cannot be avoided, do so only
after performing the following:
1. Apply the brakes and hold.
2. Have someone place wheel blocks un- der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, release your brakes slowly until the
blocks absorb the load.

4. Apply the parking brake firmly.
5. Shift into first or reverse (manual) orPº (automatic) and turn off the engine.
When restarting out after parking on a
slope:
1. With the transmission in Pº position (automatic) or the clutch pedal de-
pressed (manual), start the engine.
(With an automatic transmission, be
sure to keep the brake pedal de-
pressed.)
2. Shift into gear.
3. Release the parking brake (also foot brake on automatic transmission ve-
hicles) and slowly pull or back away
from the wheel blocks. Stop and apply
your brakes.
4. Have someone retrieve the blo cks.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.
Getting more kilometers/mileage from a
liter/gallon of fuel is easyÐjust 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 Chapter
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 warm- up idling. Once
the engine is running smoothly, begin
drivingÐbut gently. Remember, howev-
er, that on cold winter days this may
take a little longer.

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.
