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
198 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.
The standard tire should be re-
paired and reinstalled as soon
as possible.
Avoid sudden acceleration,
sudden deceleration and sharp
turns with the compact spare
tire.

153 NOTICE
Your ground clearance is re-
duced when the compact spare
tire is installed so avoid driving
over obstacles and drive slowly
on rough, unpaved roads and
speed bumps. Also, do not at-
tempt to go through an automatic
car wash as the vehicle may get
caught, resulting in damage.
1. Open the luggage storage box
and get the required tool and
spare tire.
1. Jack
2. Jack handle
3. Wheel nut wrench
4. Flat tire net
5. Spare tire
To open the luggage storage box, see

To remove the jack, move the driver
seat to the front−most position and re-
move the cover.
To rem ov e: Tur n the joint in direction
1 by hand until the jack is free.
To store: Turn the joint in direction 2
by hand until the jack is firmly secured
to prevent it flying forward during a
collision or sudden braking.To remove the spare tire, loosen the
bolt and remove it.
Then take the spare tire out of the
vehicle.
When storing the spare tire, put it in
place with the outer 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.
The compact tire storage area is de-
signed only for a compact spare tire.
Standard size tire cannot be stored
in this storage area.
—Blocking the wheel
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.

—Raising your vehicle
SY41014a
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 vehicle, 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.
CAUTION
Never get under the vehicle when
the vehicle is supported by the
jack alone.
—Changing wheels
SY41015
6. Remove the wheel nuts and
change 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.

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.

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.

200
Rotating tires
To equalize the wear and help ex-
tend tire life, Scion recommends
that you rotate your tires accord-
ing to the maintenance schedule.
(For scheduled maintenance infor-
mation, please refer to the “Sched-
uled Maintenance Guide”.) Howev-
er, the most appropriate timing for
tire rotation may vary according to
your driving habits and road sur-
face conditions.
See “If you have a flat tire” on page
150 for tire change procedure.When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire infla-
tion pressure, improper wheel align-
ment, out−of−balance wheels, or se-
vere braking.
CAUTION
Do not include a compact spare
tire when rotating the tires. It is
designed for temporary use only.
WHEN TO USE SNOW TIRES OR
CHAINS
Snow tires or chains are recommended
when driving on snow or ice.
On wet or dry roads, conventional tires
provide better traction than snow tires.
SNOW TIRE SELECTION
If you need snow tires, select tires of
the same size, construction and load
capacity as the originally installed tires.
Do not use tires other than those men-
tioned above. Do not install studded tires
without first checking local regulations for
possible restrictions.
CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
Do not use snow tires other than the
manufacturer ’s recommended size, as
this may cause dangerous handling
characteristics resulting in loss of
control.
Installing snow tires and
chains

201
SNOW TIRE INSTALLATION
Snow tires should be installed on all
wheels.
Installing snow tires on the front wheels
only can lead to an excessive difference
in road grip capability between the front
and rear tires which could cause loss of
vehicle control.
When storing removed tires you should
store them in a cool dry place.
Mark the direction of rotation and be sure
to install them in the same direction when
replacing.
CAUTION
Do not drive with the snow tires
incorrectly inflated.
Never drive over 120 km/h (75 mph)
with any type of snow tires.
TIRE CHAIN SELECTION
Use the tire chains of correct size and
type.
Use SAE Class “S” type radial tire chains
except radial cable chains or V−bar type
chains.
Regulations regarding the use of tire
chains vary according to location or
type of road, so always check local reg-
ulations before installing chains.
CHAIN INSTALLATION
Install the chains on the front tires as
tightly as possible. Do not use tire
chains on the rear tires. Retighten
chains after driving 0.5—1.0 km
(1/4—1/2 mile).
When installing chains on your tires, care-
fully follow the instructions of the chain
manufacturer.
If wheel covers are used, they will be
scratched by the chain band, so remove
the covers before putting on the chains.CAUTION
Do not exceed 50 km/h (30 mph) or
the chain manufacturer ’s recom-
mended speed limit, whichever is
lower.
Drive carefully avoiding bumps,
holes, and sharp turns, which may
cause the vehicle to bounce.
Avoid sharp turns or lockedwheel
braking, as use of chains may ad-
versely affect vehicle handling.
When driving with chains installed,
be sure to drive carefully. Slow
down before entering curves to
avoid losing control of the vehicle.
Otherwise an accident may occur.
NOTICE
Do not attempt to use a tire chain on
the compact spare tire, as it may re-
sult in damage to the vehicle as well
as the tire.
