Tire inflation pressure
Check the pressure with a gauge ev-
ery two weeks, or at least once a
month. See page 209 for additional
information.
Tire surface and wheel nuts
Check the tires carefully for cuts,
damage or excessive wear. See page
211 for additional information. When
checking the tires, make sure no nuts
are missing, and check the nuts for
looseness. Tighten them if necessary.
Tire rotation
Rotate the tires
according to the
maintenance schedule. (For sched-
uled maintenance information, please
refer to the “Scheduled Maintenance
Guide” or “Owner ’s Manual Supple-
ment”.) See page 213 for additional
information.
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 fluid leak under the vehicle (however,
water 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 If you notice any of these clues, take your
vehicle to your Scion dealer as soon as
possible. It probably needs adjustment or
repair.
CAUTION
Do not continue driving with the ve-
hicle unchecked. It could result in se-
rious vehicle damage and possibly
personal injury.

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 ignition is off if
you work near the electric cooling
fans or radiator grille. With the
ignition on, the electric cooling fans
will automatically start to run if the
engine coolant temperature is high
and/or the air conditioning 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.

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
jack. Personal injury may occur.
Do not start or run the engine while
your vehicle is supported by the
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 wheel diagonally opposite
to the one being changed if neces-
sary.
Make sure to set the jack properly
in the jack point. Raising the ve-
hicle with jack improperly posi-
tioned will damage the vehicle or
may allow the vehicle to fall off the
jack and cause personal injury.
Never get under the vehicle when
the vehicle is supported by the jack
alone; use vehicle support 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 jack.
NOTICE
Make sure to place the jack correctly,
or your vehicle may be damaged.

SECTION 7 2

207
If either of the above parts are extremely
dirty or you are not sure of their condi-
tion, take your vehicle to a Scion dealer.
CAUTION
To prevent burning yourself, be care-
ful not to touch the radiator or con-
denser when the engine is hot.
NOTICE
To prevent damage to the radiator
and condenser, do not perform the
work by yourself.
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.
Checking the radiator and
condenser

215
TIRE CHAIN SELECTION
Use the tire chains of correct size and
type.
Use SAE Class “S” type radial tire chains
except radial cable chains or V−bar type
chains.
Regulations regarding the use of tire
chains vary according to location or
type of road, so always check local reg-
ulations before installing chains.
CHAIN INSTALLATION
Install the chains on the front tires as
tightly as possible. Do not use tire
chains on the rear tires. Retighten
chains after driving 0.5 – 1.0 km (1/4 –
1/2 mile).
When installing chains on your tires, care-
fully follow the instructions of the chain
manufacturer.
If wheel covers are used, they will be
scratched by the chain band, so remove
the covers before putting on the chains.CAUTION
Do not exceed 50 km/h (30 mph) or
the chain manufacturer ’s recom-
mended speed limit, whichever is
lower.
Drive carefully avoiding bumps,
holes, and sharp turns, which may
cause the vehicle to bounce.
Avoid sharp turns or lockedwheel
braking, as use of chains may ad-
versely affect vehicle handling.
When driving with chains installed,
be sure to drive carefully. Slow
down before entering curves to
avoid losing control of the vehicle.
Otherwise an accident may occur.
NOTICE
Do not attempt to use a tire chain on
the compact spare tire, as it may re-
sult in damage to the vehicle as well
as the tire.
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.
