SECTION 7– 2

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.
Checking the radiator and
condenser

236
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 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.

Replacing wheels
As you might have difficulty in identify-
ing a flat or deflated tire, a tire pres-
sure warning system is provided on
this vehicle.
When replacing the wheels, be sure to
install tire pressure warning valves and
transmitters on the wheels. Consult your
Scion dealer about how to set up the tire
pressure warning valves and transmitters.
CAUTION
Have the tires, wheels or tire pres-
sure warning valves and transmit-
ters replaced and ID codes regis-
tered by Scion dealer. If you need
tire pressure warning valves and
transmitters, purchase from Scion
dealer.
The tire pressure warning valve and
transmitter nuts should always be
tightened to a torque of 4 N·m (0.4
kgf·m, 2.9 ft·lbf).
The use of nongenuine wheels may
result in the tire pressure warning
system failure or airleak.
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
Observe the following instruction.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
Do not use wheels other than the
manufacturer ’s recommended size, as
this may cause dangerous handling
characteristics resulting in loss of
control.

automatic transmission fluid only if your
vehicle is driven under one of the Special
Operating Conditions listed in your
“Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”. When
changing the automatic transmission fluid,
use only “Toyota Genuine ATF WS” (ATF
JWS3324 or NWS9638) to aid in assuring
optimum transaxle performance.
Notice: Using automatic transmission
fluid other than “Toyota Genuine ATF

quality, locking up of your transmission
accompanied by vibration, and ultimate-
ly damage the automatic transmission
of your vehicle.
