3. Look for obvious coolant leaks from theradiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has
been used.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.
4. If the coolant is leaking, stop the en-gine immediately. Call a Scion dealer
for assistance.
5. If there are no obvious leaks, check the coolant reservoir. If it is dry, add
coolant to the reservoir while the en-
gine is running. Fill it about half full.
CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
6. After the engine coolant temperaturehas cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You should have it checked as
soon as possible at your Scion dealer.
If you have a flat tire—
1. Reduce your speed gradually, keeping a straight line. Move cau-
tiously off the road to a safe place
well away from the traffic. Avoid
stopping on the center divider of
a highway. Park on a level spot
with firm ground.
2. Stop the engine and turn on your emergency flashers.
3. Firmly set the parking brake and put the transmission in “P” (auto-
matic) or reverse (manual).
4. Have everyone get out of the ve- hicle on the side away from traffic.
5. Read the following instructions thoroughly.

Compact spare tire
The compact spare tire is designed
for temporary emergency use only.
The compact spare tire is identified
by the distinctive wording “TEM-
PORARY USE ONLY” molded into the
side wall of the tire.
To keep the compact spare tire no-
ticeable, do not hide the wheel by a
wheel cover or such.The compact spare tire saves space
in your luggage compartment, and its
lighter weight helps to improve fuel
economy and permits easier installa-
tion in case of a flat tire.
The compact spare tire can be used
many times, if necessary. It has tread
life of up to 4800 km (3000 miles) de-
pending on road conditions and your
driving habits. When tread wear indi-
cators appear on the tire, replace the
tire.
See also the tire information on page
217 for details on the tread wear indi-
cators and other service information.
CAUTION

The compact spare tire was de-
signed especially for your
Scion. Do not use it on any oth-
er vehicle.
 Do not use more than one com-
pact spare tire at the same
time.
 The pressure for the compact
spare tire must be 420 kpa (4.2
kgf/cm
2
or bar, 60 psi).
 Do not exceed 80 km/h (50
mph) when driving with the
compact spare tire.
 Replace the compact spare tire
with the standard tire as soon
as possible.
 Avoid sudden a cceleration,
sudden d eceleration and sharp
turns with the compact spare
tire.

182
CAUTION
Make sure the rear seats are in
their original position.
 When carrying the flat tire, se-
cure it using a tire tie–down
belts. Otherwise, the flat tire
may fly out in case of the sud-
den braking or an accident, re-
sulting in death or serious inju-
ry.
—After changing wheels
10. Check the air pressure of the re-
placed tire.
Adjust the air pressu re to the specifi-
cation designed on page 237. If the
pressure is lower, dr ive slowly to the
nearest service station and fill to the
correct pressure.
Do not forget to reinstall the tire infla-
tion valve cap as dirt and moisture
could get into th e valve core and
possibly cause air leakage. If the cap
is missing, have a new one put on as
soon as possible.
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 237 with a
torque wrench and have a technician
repair the flat tire.
After repairing the flat tire, change it
with compact spare tire and reinstall
the wheel ornament.
Initial adjustment of the tire pres-
sure warning system is necessary
after you have replaced your tires
or wheels. See “Tire pressure
warning system” on page 107.CAUTION
Take due care in handling the or-
nament to avoid unexpected per-
sonal injury.

Tire inflation pressure
Check the pressure with a gauge ev-
ery two weeks, or at least once a
month. See page 215 for additional
information.
Tire surface and wheel nuts
Check the tires carefully for cuts,
damage or excessive wear. See page
217 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”.) See page 219 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.

Keep your tire inflation pressures
at the proper level.
The recommended cold tire inflation
pressures, tire sizes and the com-
bined weight of occupants and cargo
(vehicle capacity weight) are de-
scribed on page 234 and 237. They
are also described on the tire and
loading information label as shown.
You should check the tire inflation
pressures every two weeks, or at
least once a month. And do not forget
the spare!
The following instructions for
checking tire inflation pressure
should be observed:
 The pressure s hould be
checked only when the tires are
cold. If your vehicle has been
parked for at least 3 hours and has
not been driven for more than 1.5
km or 1 mile since, you will get
an accurate cold tire inflation pres-
sure reading. 
Always use a tire pressure
gauge. The appearance of a tire
can be misleading. Besides, tire
inflation pressures that are even
just a few pounds off can degrade
ride and handling.
 Take special care when adding
air to the compact spare tire.
The smaller tire size can gain
pressure very qu ickly. Add com-
pressed air in small quantities and
check the pressure often until it
reaches the specified pressure.
 Do not bleed or reduce tire
inflation pressure after driving.
It is normal for the tire inflation
pressure to be higher after driving.
 Never exceed the vehicle capac-
ity weight. Passenger and lug-
gage weight should be located so
that the vehicle is balanced.
Checking tire inflation
pressure

Tire pressure gauge
INSPECTION AND ADJUSTMENT
PROCEDURE
1. Remove the tire valve cap.
2. Press the tip of the tire pressure
gauge to the tire valve.
3. Read the pressure using gradua- tions of the gauge.
4. In case the tire inflation pressure
is not within the prescribed range,
insert the compressed air from the
valve. In case of applying too much
air, press the center of the valve
and release the air to adjust. 5. After completing the tire inflation
pressure measurement and adjust-
ment, apply soapy water to the
valve and check for leakage.
6. Install the tire valve cap. If a gauge and air pump are not avail-
able, have your vehicle checked by
your Scion dealer.
CAUTION
Be sure to reinstall the tire valve
caps. Without the valve caps, dirt
or moisture could get into the
valve core and cause air leakage.
If the caps have been lost, have
new ones put on as soon as pos-
sible.
Incorrect tire infl ation pressure may
waste fuel, reduce the comfort of driv-
ing, reduce tire life and make your ve-
hicle less safe to drive.
If a tire frequently needs refilling,
have it checked by your Scion dealer.
CAUTION
Keep your tires properly inflated.
Otherwise, the following condi-
tions may occur and cause an ac-
cident resulting in death or seri-
ous injuries.
Low tire pressure ( underinfla-
tion)—
 Excessive wear
 Uneven wear
 Poor handling
 Possibility of blowouts from an
overheated tire
 Poor sealing of the tire bead
 Wheel deformation and/or tire
separation
 A greater possibility of tire
damage from road hazards

217
High tire pressure (overinfla-
tion)—
Poor handling
 Excessive wear
 Uneven wear
 A greater possibility of tire
damage from road hazardsTread wear indicator
CHECKING YOUR TIRES
Check the tire’s tread for tread
wear indicators. If the indicators
show, replace the tires. The loca-
tion of tread wear indicators is
shown by the “TWI” or “
Δ” marks,
etc., molded on the sidewall of
each tire. The tires on your Scion have built–in
tread wear indicators to help you
know when the tires need replace-
ment. When the tread depth wears to
1.6 mm (0.06 in.) or less, the indica-
tors will appear. If you can see the
indicators in two or more adjacent
grooves, the tire should be replaced.
The lower the tread, the higher the
risk of skidding.
Vehicles equipped with Scion
215/45ZR17 tires:
Your Scion has
been fitted with specially developed
tires which provide exceptional dy-
namic performance under general
road conditions. However your riding
comfort may worsen a little and road
noise may increase during driving.
You may also notice that your tires
will wear more rapidly and tire grip
performance will be reduced on the
snowy and/or icy roads when
compared to standard tires. Be sure
to have snow tires or tire chains on
the snowy and/or icy roads and drive
carefully with the speed appropriate
for road conditions.
