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 non–s ilicate,
non–amine, non–nitrite, and non–bo-
rate coolant with long–life 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.

Low level Full level
Add oil O.K. Too full
With the engine at operating tempera-
ture and turned off, check the oil level
on the dipstick. 1. To get a correct reading, the vehicle should be on level ground. After turning
off the engine, wait a few minutes for
the oil to drain back into the bottom of
the engine.
2. Pull the dipstick out, hold a rag under the end and wipe it clean.
3. Reinsert the dipstick—Push it in as far as it will go, or the reading will not be
correct.
4. Pull the dipstick out and look at the oil level while holding a rag under the
end.
CAUTION
Be careful not to touch the hot ex-
haust manifold.
NOTICE
Be careful not to drop engine oil on
the vehicle components.
If the oil level is below or only slightly
above the low level, add engine oil of
the same type as already in the engine.
Remove the oil filler cap and add engine
oil in small quantities at a time, checking
the dipstick. We recommend that you use
a funnel when adding oil.
The approximate quantity of oil needed to
raise the level between low and full on the
dipstick is indicated below for reference.
When the level reaches within the correct
range, install the filler cap hand–tight.
Oil quantity, L (qt., lmp.qt.):1.0 (1.1, 0.9)
NOTICE
 Be careful not to spill engine oil on
the vehicle components.
 Avoid overfilling, or the engine
could be damaged.
 Check the oil level on the dipstick
once again after adding the oil.

Oil identification marks
Either or both API registered marks are
added to some oil containers to help
you select the oil you should use.
The API Service Symbol is located any-
where on the outside of the container.
The top portion of the label shows the oil
quality by API (American Petroleum Insti-
tute) designations such as SL. The center
portion of the label shows the SAE viscos-
ity grade such as SAE 5W–30. “Ener-
gy–Conserving” shown in the lower por-
tion, indicates that the oil has fuel–saving
capabilities.
The ILSAC (International Lubricant Stan-
dardization and Approval Committee) Certi-
fication Mark is displayed on the front of
the container.
To ensure excellent lubrication perfor-
mance for your engine, “Genuine Motor
Oil” is available, which has been specifi-
cally tested and approved for all Scion
engines.
Please contact your Scion dealer for fur-
ther details about “Genuine Motor Oil”.Look at the see–through coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the “FULL” and “LOW” lines on the
reservoir. If the level is low, add the
coolant. (For the coolant type, see
“Coolant type selection” described be-
low.)
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the “LOW” line, add
coolant. Bring the level up to the “FULL”
line.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, engine coolant filler cap,
radiator cap and drain cock and water
pump.
If you can find no leak, have your Scion
dealer test the cap pressure and check
for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.
Coolant type selection
Use of improper coolants may damage
your engine cooling system.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non–silicate, non–amine, non–nitrite,
and non–borate coolant with long–life hy-
brid organic acid technology. (Coolant with
long–life hybrid organic acid technology is
a combination of low phosphates and or-
ganic acids.)
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. This coolant provides protection
down to about –35
C (–31 F).
NOTICE
Do not use plain water alone.
Checking the engine coolant

Scion recommends “Toyota Super Long
Life Coolant”, which has been tested to
ensure that it will not cause corrosion nor
result in malfunction of your engine cool-
ant system with proper usage. “Toyota Su-
per Long Life Coolant” is formulated with
long–life hybrid organic acid technology
and has been specifically designed to
avoid engine cooling system malfunction
on Scion vehicles.
Please contact your Scion dealer for fur-
ther details.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 see–through 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 refi
lling, 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.
Checking the radiator and
condenser

214
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 reservoir
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.

Check the fluid level through the reser-
voir. If necessary, add automatic trans-
mission fluid DEXRON
II or III.
If the vehicle has been driven around 80
km/h (50 mph) for 20 minutes (a little
more in frigid temperatures), the fluid is
hot (60 C–80 C or 140 F–175 F). You
may also check the level when the fluid
is cold (about room temperature,
10 C–30 C or 50 F–85 F) if the engine
has not been run for about five hours. Clean all dirt from outside of the reservoir
tank and look at the fluid level. If the fluid
is cold, the level should be in the “COLD”
range. Similarly, if it is hot, the fluid level
should be in the “HOT” range. If the level
is at the low side of either range, add
automatic transmission fluid DEXRON
II or
III to bring the level within the range.
To remove the reservoir cap, turn it coun-
terclockwise and lift up. To reinstall it,
turn it clockwise. After replacing the reser-
voir cap, visually check the steering box
case, vane pump and hose connections
for leaks or damage.
CAUTION
The reservoir tank may be hot so be
careful not to burn yourself.
NOTICE
Avoid overfilling, or the power steer-
ing could be damaged.

NOTICE
Be sure the engine and all accesso-
ries are off before performing main-
tenance.
 When checking the battery, remove
the ground cable from the negative
terminal (“–” mark) first and rein-
stall it last.
 Be careful not to cause a short cir-
cuit with tools.
 Take care no solution gets into the
battery when washing it.
If the battery is disconnected or run
down, the power window, back door and
panorama moonroof may not operate auto-
matically and the jam protection function
will not function correctry and does not
open the back door after you reconnect,
replace or recharge the battery. In any of
these cases, you should normalize each
system. To normalize them, see “Power
windows” on page 18, “Back door” on
page 20 and “Panorama moonroof” on
page 24.
