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.

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 auto-
matic car wash as the vehicle
may get caught, resulting in
damage.

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.

176 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.

177
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 guide
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.

178
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.

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.

218NOTICE
Low profile tire like 215/45ZR17
may have greater damage than
usual tires to its tire wheel
when receiving impact from the
road surface. Therefore, pay
attention to the followings.

Be sure to use with proper
tire pressure. If the tire pres-
sure is low, the tire may
have a greater damage. For
detailed information about
tire pressure, see page 237.
 Avoid driving onto high,
sharp–edged objects and oth-
er road hazards. Failure to
do so can lead to severe tire
damage.
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 e
nough to
expose the fabric, or bulges indi-
cating internal damage, the tire
should be repl aced.
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. 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 144 and 141.

220 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
Do not use snow tires other than the
manufacturer ’s recommended size, as
this may cause dangerous handling
characteristics resulting in loss of
control. Otherwise, an accident may
occur resulting in death or serious
injuries.
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.

Side chain
Cross chain
TIRE CHAIN SELECTION
Use the tire chains of correct size.
For 215/45ZR17 tires, use the following
type chains. mm (in.)
A Diameter of side chain: 3.5 (0.14)
B Diameter if cross chain: 4.0 (0.16) Regulations regarding the use of tire
chains vary according to location or
type of road, so always check local reg-
ulations before installing chains.
NOTICE
If the wrong combination of tire and
chain is used, the chains could dam-
age the vehicle body.
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 locked–wheel
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.
