To tighten
To loosen
Hook the 2 hooks and adjust the belt
so that the strap does not allow the
slack.CAUTION
After installation, rock the flat
tire lightly to make sure the net
is securely hooked. Loose net
installation may cause the
hook to come off and the tire
to fly out of the net in case of
sudden braking or collision, re-
sulting in death or serious inju-
ry.
With the flat tire installed,
avoid driving on the rough
r o a d or f o r a lo n g t i m e . T h e be l t
may be loosened and come off.
—After changing wheels
10. Check the air pressure of the re-
placed tire.
Adjust the air pressure to the specifi-
cation designed on page 217. If the
pressure is lower, drive 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 the 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 217 with a
torque wrench and have a technician
repair the flat tire.

179 Tire pressure
Check the pressure with a gauge ev-
ery two weeks, or at least once a
month. See page 195 for additional
information.
Tire surface and wheel nuts
Check the tires carefully for cuts,
damage or excessive wear. See page
198 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 200 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 normalIf 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.

a. Clean all dirt from outside of the reser-
voir tank.
b. Remove the rubber cap.
c. Remove the reservoir cap by turning it
counterclockwise and wipe the dipstick
clean.
d. Reinstall the reservoir cap.
e. Remove the reservoir cap again and
look at the fluid level. If the fluid is
cold, the level should be in the “COLD”
range on the dipstick. 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 DEXRONII or III to
bring the level within the range.f. After replacing the reservoir cap and
rubber cap, visually check the steering
box case, vane pump and hose con-
nections 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.

Checking tire inflation
pressure

196 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 214 and 217. 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 should 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 quickly. 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.
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 the grad-
uations 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.

197 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 inflation 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
High tire pressure (overinfla-
tion)—
Poor handling
Excessive wear
Uneven wear
A greater possibility of tire
damage from road hazards

Checking and replacing tires
Tread 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.
The effectiveness of snow tires is
lost if the tread wears down below
4 mm (0.16 in.).
If you have tire damage such as
cuts, splits, cracks deep enough to
expose the fabric, or bulges indi-
cating internal damage, the tire
should be replaced.
If a tire often goes flat or cannot be
properly repaired due to the size or
location of a cut or other damage, it
should be replaced. If you are not
sure, consult with your Scion dealer.
If air loss occurs while driving, do not
continue driving. Driving even a short
distance can damage a tire beyond
repair.An y ti res wh i ch are over 6 years
old must be checked by a qualified
technician even if damage is not
obvious.
Tires deteriorate with age even if they
have never or seldom been used.
This applies also to the spare tire and
tires stored for future use.

199 REPLACING YOUR TIRES
When replacing a tire, use a tire of
the same size and construction,
and the same or greater maximum
load as the originally installed
tires.
Using any other size or type of tire
may seriously affect handling, ride,
speedometer/odometer calibration,
ground clearance, and clearance be-
tween the body and tires or snow
chains.
Check that the maximum load of the
replaced tire is greater than 1/2 of the
Gross Axle Weight Ratings (GAWR)
of either the front axle or the rear
axle, whichever is greater. As for the
maximum load of the tire, see the load
limit at maximum cold tire inflation
pressure mentioned on the sidewall
of the tire, and as for the Gross Axle
Weight Ratings (GAWR), see the Cer-
tification Label. For details about the
sidewall of the tire and the Certifica-
tion Label, see pages 125 and 123.
CAUTION
Observe the following instruc-
tions. Otherwise, an accident
may occur resulting in death or
serious injuries.
Do not mix radial, bias belted,
or biasply tires on your ve-
hicle, as this may cause dan-
gerous handling characteris-
tics resulting in loss of control.
Do not use tires other than the
manufacturer’s recommended
size, as this may cause danger-
ous handling characteristics
resulting in loss of control.
Scion recommends all four tires, or
at least both of the front or rear
tires be replaced at a time as a set.
See “If you have a flat tire” on page
150 for tire change procedure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect ve-
hicle handling and tire life. Wheels
can get out of balance with regular
use and should therefore be balanced
occasionally.
When replacing a tubeless tire, the
air valve should also be replaced
