If you are a skilled do−it−yourself
mechanic, the Scion service manuals are
recommended. Please be aware that
do− it−yourself maintenance can affect your
warranty coverage. See “Owner ’s Warranty
Information Booklet” or “Owner ’s Manual
Supplement” for the details.
General maintenance
Listed below are the general maintenance
items that should be performed as fre-
quently as specified. In addition to check-
ing the items listed, if you notice any
unusual noise, smell or vibration, you
should investigate the cause or take your
vehicle to your Scion dealer or a qualified
service shop immediately. It is recom-
mended that any problem you notice be
brought to the attention of your dealer or
the qualified service shop for their advice.
CAUTION
Make these checks only with ade-
quate ventilation if you run the en-
gine.
IN THE ENGINE COMPARTMENT
Items listed below should be checked
from time to time, e.g. each time when
refueling.
Washer fluid
Make sure there is sufficient fluid in the
tank. See page 211 for additional informa-
tion. Engine coolant level
Make sure the coolant level is between
the “FULL” and “LOW” lines on the see
−
through reservoir when the engine is cold.
See page 196 for additional information.
Radiator, condenser, and hoses
Check that the front of the radiator and
condenser are clean and not blocked with
leaves, dirt or insects. See page 197 for
additional information.
Battery electrolyte level
Make sure the electrolyte level of all bat-
tery cells is between upper and lower lev-
el lines on the case. Add only distilled
water when replenishing. See page 209 for
additional information.
Brake fluid level
Make sure the brake fluid level is correct.
See page 197 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 page 194 for addi-
tional information.
Power steering fluid level
Check the level through the reservoir. The
level should be in the “HOT” or “COLD”
range depending on the fluid temperature.
See page 198 for additional information.

184
Some states have vehicle emission in-
spection programs which include OBD
(On−Board Diagnostics) che cks.
The OBD system monitors the operation
of the emission control system. When the
OBD system determines that a problem
exists somewhere in the emission control
system, the malfunction indicator lamp
comes on. In this case, your vehicle may
not pass the I/M test and need to be
repaired. Contact your Scion dealer to ser-
vice the vehicle.
Even if the malfunction indicator lamp
does not come on, your vehicle may not
pass the I/M test as readiness codes
have not been set in the OBD system.
Readiness codes are automatically set
during ordinary driving. However, when the
battery is disconnected or run down, the
codes are erased. Also, depending on
your driving habits, the codes may not be
completely set.
Also, if the malfunction indicator lamp had
come on recently due to temporary mal-
function such as a loose fuel tank cap,
your vehicle may not pass the I/M test. The malfunction indicator lamp will go off
after taking several driving trips, but the
error code in the OBD system will not be
cleared unless about 40 trips or more are
taken.
If your vehicle does not pass the I/M test
even the malfunction indicator lamp does
not come on, contact your Scion dealer to
prepare the vehicle for re
−testing.

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.

NOTICE
Remember that battery and ignition
cables carry high currents or volt-
ages. Be careful of accidentally
causing a short circuit.
 Add only “Toyota Super Long Life
Coolant” or similar high quality eth-
ylene glycol based nonsilicate,
nonamine, nonnitrite and nonbo-
rate coolant with longlife hybrid
organic acid technology to fill the
radiator. “Toyota Super Long Life
Coolant” is a mixture of 50% cool-
ant and 50% deionized water.
 If you spill some of the coolant, be
sure to wash it off with water to
prevent it from damaging the parts
or paint.
 Do not allow dirt or anything else
to fall through the spark plug holes.
 Use only spark plugs of the speci-
fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
 Do not overfill automatic transmis-
sion fluid and power steering fluid,
or the transmission and power
steering could be damaged.
Do not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.
 Be careful not to scratch the glass
surface with the wiper frame.
 When closing the engine hood,
check to see that you have not for-
gotten any tools, rags, etc.

CAUTION
BATTERY PRECAUTIONS
The battery produces flammable and
explosive hydrogen gas.
Do not cause a spark from the bat-
tery with tools.
Do not smoke or light a match near
the battery.
The electrolyte contains poisonous
and corrosive sulfuric acid.
Avoid contact with eyes, skin or
clothes.
Never ingest electrolyte.
Wear protective safety glasses when
working near the battery.
Keep children away from the bat-
tery.
EMERGENCY MEASURES
If electrolyte gets in your eyes,
flush your eyes with clean water
immediately and get immediate
medical attention. If possible, con-
tinue to apply water with a sponge
or cloth while en route to the medi-
cal office.
If electrolyte gets on your skin,
thoroughly wash the contact area. If
you feel pain or burning, get medi-
cal attention immediately.
If electrolyte gets on your clothes,
there is a possibility of its soaking
through to your skin, so immediate-
ly take off the exposed clothing and
follow the procedure above, if nec-
essary.
If you accidentally swallow electro-
lyte, drink a large quantity of water
or milk. Follow with milk of magne-
sia, beaten raw egg or vegetable
oil. Then go immediately for emer-
gency help.
—Checking battery exterior
Hold −down clampTerminals
Ground cable
Check the battery for corroded or loose
terminal connections, cracks, or loose
holddown clamp.
a. If the battery is corroded, wash it off with a solution of warm water and bak-
ing soda. Coat the outside of the termi-
nals with grease to prevent further cor-
rosion.
b. If the terminal connections are loose, tighten their clamp nuts—but do not
overtighten.
c. Tighten the hold −down clamp only
enough to keep the battery firmly in
place. Overtightening may damage the
battery case.
