When driving off±road or in rugged
terrain, do not drive at excessive
speeds, jump, make sharp turns,
strike objects, etc. This may cause
loss of control or vehicle rollover
causing death or serious injury. You
are also risking expensive damage
to your vehicle's suspension and
chassis.

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.
Break±in period
Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
break±in. But following a few simple tips
for the first 1600 km (1000 miles) can add
to the future economy and long life of
your vehicle:

Do not drive over 88 km/h (55 mph).

Run the engine at moderate speed be-
tween 2000 and 4000 rpm.

Avoid full±throttle starts.

Try to avoid hard stops during the first
300 km (200 miles).

Do not drive slowly with the manual
transmission in a high gear.

Do not drive for a long time at any
single speed, either fast or slow.

Do not tow a trailer during the first 800
km (500 miles).
Fuel
FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mix±ups, your
Toyota has a smaller fuel tank opening.
The special nozzle on pumps with un-
leaded fuel will fit it, but the larger stan-
dard nozzle on pumps with leaded gas will
not.
At a minimum, the gasoline you use
should meet specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5±M93
in Canada.
NOTICE
Do not use leaded gasoline. Use of
leaded gasoline will cause the three±way catalytic converter to lose its ef-fectiveness and the emission control
system to function improperly. Also,this can increase maintenance costs.

Suspension and chassis
CAUTION
Do not modify the suspension/chassis
with lift kits, spacers, springs, etc. It
can cause dangerous handling charac-
teristics, resulting in loss of control.
Types of tires
Determine what kind of tires your ve-
hicle is originally equipped with.
1. Summer tires
Summer tires are high±speed capab ility
tires best suited to highway driving under
dry 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
adequate traction performance compared
with snow tires in heavy or loose snow.
Also, all season tires fall short in accel-
eration and handling performance
compared with summer tires in highway
driving.CAUTION

Do not mix summer and all season
tires on your vehicle as this can
cause dangerous handling charac-
teristics, resulting in loss of con-
trol.

Do not use tires other than the
manufacturer 's designated tires, and
never mix tires or wheels of the
sizes different from the originals.

U.S. Forest Service and Bureau of
Land Management
CAUTION
Always observe the following precau-
tions to minimize the risk of serious
personal injury or damage to your ve-
hicle:

Drive carefully when off the road.
Do not take unnecessary risks by
driving in dangerous places.

Do not grip the steering wheel
spokes when driving off±road. A
bad bump could jerk the wheel and
injure your hands. Keep both hands
and especially your thumbs on the
outside of the rim.

Always check your brakes for effec-
tiveness immediately after driving in
sand, mud, water or snow.

After driving through tall grass,
mud, rock, sand, rivers, etc., check
that there is no grass, bush, paper,
rags, stone, sand, etc. adhering or
trapped on the underbody. Clear off
any such matter from the under-
body. If the vehicle is used with
these materials trapped or adhering
to the underbody, a breakdown or
fire could occur.

In a rollover crash, an unbelted per-
son is significantly more likely to
die than a person wearing a seat
belt. Therefore, the driver and all
passengers should fasten their seat
belts whenever the vehicle is mov-
ing.

When driving off±road or in rugged
terrain, do not drive at excessive
speeds, jump, make sharp turns,
strike objects, etc. This may cause
loss of control or vehicle rollover
causing death or serious injury. You
are also risking expensive damage
to your vehicle's suspension and
chassis.
NOTICE
If driving through water, such as
when crossing shallow streams,first check the depth of the waterand the bottom of the river bed for
firmness. Drive slowly and avoiddeep water.
Take all necessary safety measures
to ensure that water damage to theengine or other components doesnot occur.
Water entering the engine air intakewill cause severe engine damage.
Water can wash the grease fromwheel bearings, causing rusting and
premature failure, and may also en-ter the differentials, transmissionand transfer case, reducing the gear
oil's lubricating qualities.
Sand and mud that has accumulatedin brake drums and around brake
discs may affect braking efficiencyand may damage brake system com-ponents.

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 ªSched-
uled Maintenance Guideº or ªOwner '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 regulations. 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.

Battery electrolyte level
Your Toyota has a maintenance free bat-
tery. You do not have to add distilled wa-
ter. For longer life of the battery, however,
see Section 7±3 for additional information.
Brake fluid level
Make sure the brake fluid level is correct.
See Section 7±2 for additional information.
Engine oil level
Check the level on the dipstick with the
engine turned off and the vehicle parked
on a level spot. See Section 7±2 for addi-
tional information.
Power steering fluid level (5VZ±FE en-
gine)
Check the level on the dipstick. The level
should be in the ªHOTº or ªCOLDº range
depending on the fluid temperature. See
Section 7±2 for additional information.
Power steering fluid level (2UZ±FE en-
gine)
Check the level through the reservoir. The
level should be in the ªHOTº or ªCOLDº
range depending on the fluid temperature.
See Section 7±2 for additional information. Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, have
the cause located and corrected immedi-
ately. (See engine exhaust cautions in
Section 2.)
Be on the alert for changes in perfor-
mance, sounds, and visual tip±offs that
indicate service is needed. Some impor-
tant clues are as follows:

Engine missing, stumbling, or pinging

Appreciable loss of power

Strange engine noises

A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)

Change in exhaust sound (This may
indicate a dangerous carbon monoxide
leak. Drive with the windows open and
have the exhaust system checked im-
mediately.)

Flat±looking tire; excessive tire squeal
when cornering; uneven tire wear

Vehicle pulls to one side when driving
straight on a level road

Strange noises related to suspension
movement

Loss of brake effectiveness; spongy
feeling brake or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking

Engine coolant temperature continually
higher than normal
