When stowing luggage or cargo in the ve-
hicle, observe the following:
Put luggage or cargo in the trunk when
at all possible. Be sure all items are se- cured in place.
Be careful to keep the vehicle bal-
anced. Locating the weight as far for-
ward as possible helps maintain bal- ance.
For better fuel economy, do not carryunneeded weight.
CAUTION!
To prevent luggage or packages
from sliding forward during brak-
ing, do not stack anything behind
the front seats higher than the seatbacks. Keep luggage or pack-
ages low, as close to the floor as possible.
Never allow anyone to ride in the
luggage compartment. It is not de-
signed for passengers. They
should ride in their seats with their
seat belts properly fastened.
Otherwise, they are much more
likely suffer serious bodily injury,
in the event of sudden braking or a collision.
Do not place anything on the filler
panel or luggage cover. Such items may be thrown about and
possibly injure people in the ve-
hicle during sudden braking or an
accident. (secure all items in a safe
place.)
Do not drive with objects left on
top of the instrument panel. They
may interfere with the driver's field
of view. Or they may move during
sharp vehicle acceleration or turn-ing, and impair the driver's control
of the vehicle. In an accident they
may injure the vehicle occupants.
NOTICE
Do not load the vehicle beyond the vehicle capacity weight specified in
Part 8.
The vehicle identification number
(VIN) is the legal identifier for your ve- hicle. This number is on the left top of
the instrument panel, and can be seen
through the windshield from outside.
This is the primary identification number
for your T oyota. It is used in registering the
ownership of your vehicle.

Four-wheel drive modelsÐToyota
recommends not using four-wheel
drive on dry hard-surfaced roads, be-
cause four-wheel driving will cause unnecessary noise and wear, and poor
fuel economy.
Four-wheel drive modelsÐIn cold
temperatures, noise may occur when
driving in two-wheel drive before the
transfer is warmed up. Therefore, first
drive in four-wheel drive until the
transfer is warmed up.
CAUTION!
Before driving off, make sure that the parking brake if fully released
and the parking brake reminder
light is off.
Do not leave your vehicle unat-
tended while the engine is running.
Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
To drive down a long or steep hill,reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat and
not work properly.
Be careful when accelerating, up-
shifting, downshifting or braking
on a slippery surface. Sudden ac-
celeration or engine braking, could cause the vehicle to spin or skid.
Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has high-speed capability tires.
Driving over 140 km/h (85 mph) may
result in tire failure, loss of control
and possible injury. Be sure to con-
sult a tire dealer to determine
whether the tires on your vehicle
are high-speed capability tires or
not before driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a lon-ger stopping distance, and it may
pull to one side when the brakes are
applied. Also, the parking brake
will not hold the vehicle securely. When driving your vehicle off-road,
please observe the following precautions
to ensure your driving enjoyment and to
help prevent the closure of areas to off-
road vehicles.
a. Drive your vehicle only in
areas where
off-road vehicles are permitted to travel.
b. Respect private property. Get owner's
permission before entering private prop-
erty.
c. Do not enter areas that are closed.
Honor gates, barriers and signs that re-
strict travel.
d. Stay on established roads. When con-
ditions are wet, driving techniques should
be changed or travel delayed to prevent
damage to roads.
For owners in U.S. mainland, Hawaii and Puerto Rico:
To obtain additional information pertaining
to driving your vehicle off-road, consult the following organizations. State and Local Parks and Recreation Departments

The trailer cargo load should be
distributed so that the tongue load
is 9 to 11% of the total trailer weight,
not exceeding the maximum of the
following. 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.
3RZ-FE engine 158 kg (350 lb.)
5VZ-FE engine 226 kg (500 lb.) HITCHES
Use only a weight carrying hitch de-
signed for the total trailer weight. Toyo-
ta does not recommend using a weight
distribution (load equalizing) hitch.
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 havea light coat of grease.
Toyota recommends removing thehitch when not towing to prevent injury
and/or damage due to the hitch in
event of a rear end collision. After re- moval of the hitch, seal the installation
area to prevent entry of exhaust fumes
and mud.
Do not use an axle-mounting hitch as it may cause damage to the axle
housing, wheel bearings, wheelsand/ or tires.
NOTICE
BRAKES AND SAFETY CHAINS Toyota recommends trailers with
brakes that conform to any applica-
ble federal and state/provincial reg-ulations.
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 separated. For correct
safety chain procedures, follow the
hitch or trailer manufacturer's rec- ommendations.
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.

156
TIRES
Ensure that your vehicle's tires are
properly inflated. See Chapter 7-2 forinstructions.
The trailer tires should be inflated to
the pressure recommended by the
trailer manufacturer in respect to the
total trailer weight.
TRAILER LIGHTS Trailer lights must comply with federal,
state/provincial and local regulations. See your local recreational vehicle
dealer or rental agency for the correct type of wiring and relays for your trail-
er. Check for correct operation of the
turn signals and stop lights each time
you hitch up. Direct splicing may dam-
age 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 ve-
hicle with any new power train compo-
nent (engine, transmission, differen- tial, wheel bearing, etc.) for the first
800 km (500 miles) of driving. MAINTENANCE
If you tow a trailer, your vehicle will re-
quire more frequent maintenance due
to the additional load. For this informa-
tion, please refer to the scheduled
maintenance information in the Own-
er 's Manual Supplement/Maintenance Scheduleº.
Retighten all fixing bolts of the towing
ball and bracket after approximately
1000 km (600 miles) of trailer driving.
PRE-T OWING 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 suspen-
sion 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 purpose. 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, ex-
cessive speed and improper trailer
loading. Keep these in mind when tow-
ing: Before starting out, check operation of
the lights and all vehicle-trailer con-
nections. After driving a short dis-
tance, stop and recheck the lights and
connections. Before actually towing a
trailer, practice turning, stopping and
backing with a trailer in an area away
from traffic until you learn the feel.
Backing w ith a trailer is difficult and re-
quires practice. Grip the bottom of thesteering 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 procedure 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 back-
ing to reduce the risk of an accident.

167
Turn the jack joint by hand.
To remove: Turn the joint in direction 1 un- til the jack is free.
To store: Turn the joint in direction 2 until the jack is firmly secured to prevent it fly-
ing forward during a collision or suddenbraking.To remove the spare tire:
1. Insert the end of the jack handle intothe lowering screw and turn it counter- clockwise.
2. After the tire is lowered completely to the ground, remove the holding brack-et.
When storing the spare tire, put it in placewith the outer side of the wheel facing up.Then secure the tire taking care that the
tire goes straight up without catching on
any other part, to prevent it from flying for-ward during a collision or sudden braking.2. Block the wheel diagnoally oppo- site the flat tire to keep the vehicle from rolling when it is jacked up.
When blocking the wheel, place a wheel
block from the front for the front wheels or
from the rear for the rear wheels.

9. Lower the vehicle completely andtighten the wheel nuts.
Turn the jack handle extension counter-
clockwise with handle to lower the vehicle,
making sure the handle remains firmly
fitted onto the jack handle extension. Use only the wheel nut wrench to tighten the nuts. Do not use other tools or any
additional leverage other than your
hands, such as a hammer, pipe or your
foot. Make sure the wrench is securely en-
gaged over the nut.
Tighten each nut a little a time in the order
shown. Repeat the process until all the
nuts are tight.10. Reinstall the wheel ornament.
Put the wheel ornament into position and
then tap it firmly with the side or heel ofyour hand to snap it into place.
Take due care in handling the
ornament to avoid unexpected
personal injury. CAUTION
! 11. Check the air pressure of the re-
placed tire.
Adjust the air pressure to the specification
designated in Part 8. If the pressure is
lower, drive slowly to the nearest service station and fill to the correct pressure.
Do not forget to reinstall the tire inflation valve cap as dirt and moisture could get into the valve core and possibly cause air
leakage. If the cap is missing, have a new
one put on as soon as possible.
12. Restow all the tools, jack and flat
tire securely.
As soon as possible after changing
wheels, tighten the wheel nuts to the torque specified in Part 8 with a torque wrench, and have a technician repair the flat tire.
Before driving, make sure all the
tools, jack and flat tire are securely in place in their storage location to
reduce the possibility of personal
injury during a collision or suddenbraking. CAUTION
