Types of tires
This vehicle is one of the class of ve-
hicles which have higher ground
clearance and narrower tread in rela-
tion to the height of their center of
gravity to make them capable of per- forming in a wide variety of off-road applications. Specific design charac-
teristics give it a hi
gher center or grav-
ity than ordinary cars. An advantage ofthe higher ground clearance is a better view of the road allowing you to antici-
pate problems. It is not designed for
cornering at the same speeds as con-
ventional two-wheel drive vehicles
any more than low-slung sports cars
are designed to perform satisfactorily under off-road conditions.
CAUTION!
Always obeserve the following pre-
cautions to minimize the risk of seri-
ous personal injury or damage to
your vehicle: Avoid sharp turns or abrupt maneu-
vers, if at all possible. As with other
vehicles of this type, failure to oper-
ate this vehicle correctly may result
in loss of control or vehicle rol-
lover.
Avoid l oading any items on the roof
that will make the center of gravity
even higher.
Always slow down in gusty cross-
winds. Because of its high center of
gravity, your vehicle is more sensi-
tive to side winds than an ordinary
passenger car. Slowing down will
allow you to have much better con- trol.
Do not drive horizontally across
steep slopes. Driving straight up or
straight down is preferred. Your ve-
hicle (or any similar off-road ve-
hicle) can tip over sideways much
more easily than forward or back- ward.

Effective way to press the ABSº brake
pedal: When the anti-lock brake system
function is in action, you may feel the brake pedal pulsating and hear a noise.
In this situation, to let the anti-lock brake
system work for you, just hold the brake
pedal down more firmly. Do not pumpthe brake. This will result in reduced
braking performance.
The brake pedal pulsation caused by the
anti-lock brake system may indicate haz- ardous road surface conditions. Althoughthe anti-lock brake system assists in pro-
viding vehicle control, it is still important to
drive with all due care, because the anti-
lock brake system cannot overcome the
laws of physics that act on your vehicle: Braking capab ility is dependent on tire
friction with the road surface.
Even though the anti-lock brake sys-
tem is operating, a driver cannot main- tain full control on certain slippery road
surfaces, when cornering at highspeeds, or in violent maneuvers.
Avoid high speeds on wet roads. The
anti-lock brake system cannot elimi-
nate the risk of hydroplaning and lossof tire friction. Always maintain a safe distance from the
vehicle in
front of you. Compared with ve-
hicles not fitted with an anti-lock brake
system, your vehicle may require a longer
stopping distance in the following cases: Driving on rough, gravel or snow-cov-
ered roads.
Driving with tire chains installed.
Driving on roads where the road sur-
face is pitted or has other differencesin surface height.
CAUTION!
Do not use tires other than the
manufacturer 's designated tires, and
do not mix tires or wheels of different
sizes. You may prevent the antilockbrake system from operating at fulleffictiveness.
Vehicles with rear differential lock sys- temÐ
The anti-lock brake system does not op-
erate when the rear differential is locked.
It is normal operation for the ABSº warn-
ing light to be on at this time.Type A

engine block as shown.
CAUTION!
Do not modify the suspension/
chassis with lift kits, spacers,
springs, etc. It can cause danger-
ous handling characteristics, re-
sulting in loss of control. Determine what kind of tires your ve-
hicle is originally equipped with 1.
Summer tires
Summer tires are high-speed capability
tires best suited to highway driving underdry conditions. Since summer tires do not have the same
traction performance as snow tires, sum-
mer tires are inadequate for driving on
snow-covered or icy roads. For driving on
snow-covered or icy roads, we recom-
mend using snow tires. If installing snow tires, be sure to replace all four tires. 2. All season tires
All season tires are designed to provide
better traction in snow and to be adequate
for driving in most winter conditions, as
well as for use all year round.
All season tires, however, do not have ad-
equate traction performance compared
with snow tires in heavy or loose snow.
Also, all season tires fall short in accelera-
tion and handling performance compared with summer tires in highway driving.

CAUTION!
Do not mix summer and all sea-
son tires on your vehicle as this
can cause dangerous handling
characteristics, resulting in loss
of control.
Do not use tires other than the
manufacturer 's designated tires,
and do not mix tires or wheels of
the sizes different from the originals.

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.
Be careful when accelerating, up-
shifting, down shifting or braking
on a slippery surface. Sudden ac-
celeration or engine braking, could cause the vehicle to spin or skid.!
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.
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.
Hon-
or gates, barriers and signs that restrict 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:

The trailer cargo load should be
distributed so that the tongue load
is 9 to 11% of the total trailer weight,
not exceeding 158 kg (350 lb.).
However, if towing with a fifth
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
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.
If using a fifth wheel hitch, the center
of the king pin must be forward of the
axis of the vehicle's rear wheels, and
installed according to the manufactur-
er's instructions.
The hitch ball and king pin should have a light coat of grease.
Toyota recommends that the trailer
hitch, except fifth wheel hitch, be re-moved when not towing to prevent in- jury and/or damage by the hitch in
event of a rear end collision. After re-moving the hitch, the installation area
should be sealed 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 applicable
federal and state/provincial regula- tions.
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 thetongue 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.!

134
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.
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.

4. Apply the parking brake firmly.
5. Shift into first or reverse (manual) or
Pº (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 wheels blocks. Stop and ap- ply your brakes.
4. Have someone retrieve the blocks.
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) maycause loss of control.
Slow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts
Avoid holding the pedal down too
long or too frequently. This could
cause the brakes to overheat and
result in reduced braking
efficiency.
CAUTION! Getting
more kilometers/mileage from a li-
ter/gallon of fuel 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 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,
however, 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.
