CAUTION
If the tire pressure warning light
comes on, be sure to observe the
following precautions. Failure to do
so could cause loss of vehicle control
and result in death or serious injury.
Stop your vehicle in a safe place as
soon as possible. Adjust the tire
inflation pressure immediately.
If the tire pressure warning light
comes on even after tire inflation
pressure adjustment, it is probable
that you have a flat tire. Check the
tires. If the tire is flat, change to
the spare tire and have the flat tire
repaired by the nearest Scion deal-
er.
Avoid abrupt maneuvering and bra-
king. If the vehicle tires deteriorate,
you could lose control of the steer-
ing wheel or the brakes.
The tire pressure warning light may turn
on due to natural causes such as natural
air leaks or tire inflation pressure changes
caused by temperature. In this case, ad-
justing the tire inflation pressure will turn
off the light after a few minutes.
Pushing the tire pressure warning reset
switch should not turn off the tire pressure
warning light. Adjusting the tire inflation
pressure will turn off the light. The compact spare tire is not equipped
with the tire pressure warning valve and
transmitter. If a tire goes flat, the warn-
ing light will not turn off even though the
flat tire is replaced with the spare tire.
Replace the spare tire with the repaired
tire and adjust the proper tire inflation
pressure. The tire pressure warning light
will turn off after a few minutes.
CAUTION
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label (tire
and load information label). (If your
vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure label
(tire and load information label), you
should determine the proper tire infla-
tion pressure for those tires.)

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 treadwear indi-
cators appear on the tire, replace the
tire.
See also the tire information on page
239 for details on the treadwear 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.

NOTICE
Your ground clearance is reduced
when the compact spare tire is
installed so avoid driving over ob-
stacles and drive slowly on rough, un-
paved roads and speed bumps. Also,
do not attempt to go through an auto-
matic car wash as the vehicle may
get caught, resulting in damage.

2. Towing eyelet
(For emergency towing)
3. Jack handle
4. Spare tire
5. Jack
To open the luggage storage box, see
“Luggage storage box” on page 144.
To prepare yourself for an emergency,
you should familiarize yourself with
the use of the jack, each of the tools
and their storage locations.
40T026
To remove the spare tire:
1. Remove the spare tire cover.
2. Loosen the spare tire bolt and re- move it.
Then take the spare tire out of the
vehicle.
When storing the spare tire, put it in
place with the inner side of the wheel
facing up. Then secure the tire by re-
peating the above removal steps in
reverse order to prevent it from flying
forward during a collision or sudden
braking.

tire

198 The spare tire bolt is designed only
for a compact spare tire. Standard
size tire cannot be secured with it.
—Blocking the wheel
40T014
2. Block the wheel diagonally op-posite the flat tire to keep the
vehicle from rolling when it is
jacked up.
When blocking the wheel, place a
wheel block in front of one of the front
wheels or behind one of the rear
wheels.
—Loosening wheel nuts
40T015
3. Loosen all the wheel nuts. Always loosen the wheel nuts before
raising the vehicle.
Turn the wheel nuts counterclockwise
to loosen. To get maximum leverage,
fit the wrench to the nut so that the
handle is on the right side, as shown
above. Grab the wrench near the end
of the handle and pull up on the han-
dle. Be careful that the wrench does
not slip off the nut.
Do not remove the nuts yet—just un-
screw them about one–half turn.

199
CAUTION
Never use oil or grease on the
bolts or nuts. The nuts may loos-
en and the wheels may fall off,
which could cause a serious ac-
cident.
—Positioning the jack
40T016Jack point guides
4. The jack point guides are lo-cated under the side mud
guards. They indicate the jack
point positions.
Make sure the jack is positioned on
a level and solid place.
—Raising your vehicle
40T017
5. After making sure that no one is in the vehicle, raise it high
enough so that the spare tire
can be installed.
Remember you will need more ground
clearance when putting on the spare
tire than when removing the flat tire.
To raise the vehicl e, insert the jack
handle into the jack (it is a loose fit)
and turn it clockwise. As the jack
touches the vehicle and begins to lift,
double–check that it is properly posi-
tioned.

200
CAUTION
Never get under the vehicle when
the vehicle is supported by the
jack alone.
—Changing wheels
40T018
6. Remove the wheel nuts andchange tires.
Lift the flat tire straight off and put it
aside.
Roll the spare wheel into position and
align the holes in the wheel with the
bolts. Then lift up the wheel and get
at least the top bolt started through
its hole. Wiggle the tire and press it
back over the other bolts.
40T019
Before putting on wheels, remove any
corrosion on the mounting surfaces
with a wire brush or such. Installation
of wheels without good metal–to–me-
tal contact at the mounting surface
can cause wheel nuts to loosen and
eventually cause a wheel to come off
while driving.

204
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 261. 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 261 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 119.CAUTION
Take due care in handling the or-
nament to avoid unexpected per-
sonal injury.
