Always slow down in gusty cross-
winds. Because of its profile and
higher center of gravity, your ve-
hicle is more sensitive to side
winds than an ordinary passenger
car. Slowing down will allow you to
have better control.

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.
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:

Avoid full throttle acceleration when
starting and driving.

Avoid racing the engine.

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

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 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 the 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.

GASOLINE CONTAINING MMT
Some gasoline contain an octane en-
hancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl).
Toyota does not recommend the use of
gasoline that contains MMT. If fuel con-
taining MMT is used, your emission con-
trol system may be adversely affected.
The Malfunction Indicator Lamp on the in-
strument cluster may come on. If this hap-
pens, contact your Toyota dealer for ser-
vice.
GASOLINE QUALITY
In a very few cases, you may experience
driveability problems caused by the partic-
ular gasoline that you are using. If you
continue to have unacceptable driveability,
try changing gasoline brands. If this does
not rectify your problem, then consult your
Toyota dealer.NOTICE

Do not use gasohol other than
stated above. It will cause fuel sys-
tem damage or vehicle performance
problems.

If driveability problems occur (poor
hot starting, vaporizing, engine
knock, etc.), discontinue the use.

Take care not to spill gasohol dur-
ing refueling. Gasohol may cause
paint damage.
FUEL TANK CAPACITY
72.5 L (19.1 gal., 16.0 Imp. gal.)The fuel pump shut off system stops sup-
plying fuel to the engine to minimize the
risk of fuel leakage when the engine stalls
or an airbag inflates upon collision. To
restart the engine after the fuel pump shut
off system activates, turn the ignition
switch to ACCº or LOCKº once and start
it.
CAUTION
Inspect the ground under the vehicle
before restarting the engine. If you
find that liquid has leaked onto the
ground, it is the fuel system has
been damaged and it is in need of
repair. In this case, do not restart the
engine.

3. REMOVAL AND INSTALLATION OF FUEL CONTROL PARTS
(a) PLACE FOR REMOVING AND INSTALLING OF FUEL SYSTEM PARTS
(1) Work in a place with good air ventilation and without any ignition sources, such as a welder, grind-
er, drill, electric motor or stove.
(2) Never work in a place such as a pit or near a pit because vaporized fuel will collect in those places.
(b) REMOVING AND INSTALLING OF FUEL SYSTEM PARTS
(1) Prepare a fire extinguisher before starting operation.
(2) To prevent static electricity, install a ground on the fuel changer, vehicle and fuel tank, and do
not spray the area with water. The work surface will become slippery. Do not clean up spills with
water as this will spread and gasoline and create a fire hazard.
(3) Never use any electric equipment like an electric motor or a working light, as they may create
sparks or high temperatures.
(4) Never use an iron hammer, as it may create sparks.
(5) Dispose of fuel-contaminated shop rags separately using a fire resistant container.
4. REMOVAL AND INSTALLATION OF ENGINE INTAKE
PARTS
(a) If any metal particle enters the inlet pass, this may dam-
age the engine.
(b) When removing and installing the inlet system parts, cov-
er the openings of the removed parts and engine open-
ings. Use clean shop rags, gummed tape, or other suit-
able materials.
(c) When installing the inlet system parts, check that no metal
particles have entered the engine or the installed part.
5. HANDLING OF HOSE CLAMPS
(a) Before removing the hose, check the clamp position so
that you can restore it in the same way.
(b) Replace deformed or dented clamps with new ones.
(c) When reusing a hose, attach the clamp on the clamp track
portion of the hose.
(d) For a spring type clamp, to spread the tabs slightly after
installation by pushing in the direction of the arrow marks
as shown in the illustration.
6. FOR VEHICLES EQUIPPED WITH MOBILE COMMU-
NICATION SYSTEMS
(a) Install the antenna as far away from the ECU and sensors
of the vehicle electronic systems as possible.
(b) Install an antenna feeder at least 20 cm (7.87 in.) away
from the ECU and sensors of the vehicle electronic sys-
tems. For details of the ECU and sensors locations, refer
to the section on applicable components.
(c) Keep the antenna and feeder separate from other wirings
as much as possible. This will prevent signals from the
communication equipment from affecting vehicle equip-
ment and vice-versa.
(d) Check that the antenna and feeder are correctly adjusted.
(e) Do not install any high-powered mobile communication
system.
