CAUTION
When the engine is running, keep
hands, clothing, and tools away
from the moving fan and engine
drive belts. (Removing rings,
watches, and ties is advisable.)
Right after driving, the engine
compartment—the engine, radiator,
exhaust manifold and spark plug
boots, etc.—will be hot. So be care-
ful not to touch them. Oil, fluids
and spark plugs may also be hot.
If the engine is hot, do not remove
the radiator cap or loosen the drain
plugs to prevent burning yourself.
Do not leave anything that may
burn easily, such as paper or rags,
in the engine compartment.
Do not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flammable.
Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
Do not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
Be sure that the engine switch is
off if you work near the electric
cooling fans or radiator grille. With
the engine switch on, the electric
cooling fans will automatically start
to run if the engine coolant temper-
ature is high and/or the air condi-
tioning is on.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
Used engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move used engine oil from your
skin, wash thoroughly with soap
and water.
Do not leave used oil within the
reach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers or
onto the ground. Call your dealer or
a service station for information
concerning recycling or disposal.
Take care when filling the brake and
clutch reservoirs because brake or
clutch fluid can harm your hands or
eyes. If fluid gets on your hands or
in your eyes, flush the affected area
with clean water immediately. If you
still feel uncomfortable with your
hands or eyes, go to the doctor.

237
When jacking up your vehicle with the
floor jack, position the jack correctly as
shown in the illustration.CAUTION
When jacking, be sure to observe the
following to reduce the possibility of
personal injury:
Follow jacking instructions.
Do not put any part of your body
under the vehicle supported by a
floor jack. Personal injury may oc-
cur.
Do not start or run the engine while
your vehicle is supported by the
floor jack.
Stop the vehicle on a level firm
ground, firmly set the parking brake
and put the transmission in “P”
(automatic) or reverse (manual).
Block the wheels on the opposite
side of the floor jack up point if
necessary.
Make sure to set the floor jack
properly in the jack point. Raising
the vehicle with floor jack improper-
ly positioned will damage the ve-
hicle or may allow the vehicle to
fall off the floor jack and cause
personal injury.
Never get under the vehicle when
the vehicle is supported by the
floor jack alone; use vehicle sup-
port stands.
Do not raise the vehicle with some-
one in the vehicle.
When raising the vehicle, do not
place any objects on top of or un-
derneath the floor jack.
NOTICE
Make sure to place the floor jack cor-
rectly, or your vehicle may be dam-
aged.

Checking brake fluid
To check the fluid level, simply look at
the seethrough reservoir. The level
should be between the “MAX” and
“MIN” lines on the reservoir.
It is normal for the brake fluid level to go
down slightly as the brake pads wear. So
be sure to keep the reservoir filled.
If the reservoir needs frequent refilling, it
may indicate a serious mechanical prob-
lem.If the level is low, add SAE J1703 or
FMVSS No.116 DOT 3 brake fluid to the
brake reservoir.
Remove and replace the reservoir cap by
hand. Fill the brake fluid up to the “MAX”
line. This brings the fluid to the correct
level when you put the cap back on.
Use only newly opened brake fluid. Once
opened, brake fluid absorbs moisture from
the air, and excess moisture can cause a
dangerous loss of braking.
CAUTION
Take care when filling the r
eservoir
because brake fluid can harm your
hands or eyes. If fluid gets on your
hands or in your eyes, flush the af-
fected area with clean water immedi-
ately. If you still feel uncomfortable
with your hands or eyes, go to the
doctor.
NOTICE
If you spill some of the fluid, be sure
to wipe it off to prevent it from dam-
aging the parts or paintwork.

Replacing wheels
WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion, the
wheel should be replaced.
If you fail to replace damaged wheels, the
tire may slip off the wheel or cause loss
of handling control.
WHEEL SELECTION
When replacing wheels, care should be
taken to ensure that the wheels are re-
placed by ones with the same load ca-
pacity, diameter, rim width, and offset.
This must be observed on compact spare
tires, too.
Correct replacement wheels are available
at your Scion dealer.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ability, headlight
aim, bumper height, vehicle ground clear-
ance, and tire or snow chain clearance to
the body and chassis.Replacement with used wheels is not rec-
ommended as they may have been sub-
jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened may
have structural damage and therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.
CAUTION
Do not use wheels other than the
manufacturer ’s recommended size, as
this may cause dangerous handling
characteristics resulting in loss of
control. Otherwise, an accident may
occur resulting in death or serious
injuries.

“Owner ’s Manual Supplement”. When
changing the automatic transmission fluid,
use only “Toyota Genuine ATF WS” to aid
in assuring optimum transaxle
performance.
Notice: Using automatic transmission
fluid other than “Toyota Genuine ATF
WS” may cause deterioration in shift
quality, locking up of your transmission
accompanied by vibration, and ultimate-
ly damage the automatic transmission
