LOW TIRE PRESSURE WARNING LIGHT
This light comes on when the ignition key
is turned to the “ON” position. It goes off
after a few seconds. This indicates that
the tire pressure warning system is func-
tioning properly.
If the low tire pressure warning light
comes on or blinks while driving, do
the following.If the warning light comes on:
1. Adjust the tire inflation pressure to the specified level as soon as pos-
sible. (See “Tires” on page 237.)
2. Push the tire pressure warning sys- tem reset switch for a few seconds
and make sure the warning light
goes off.
If the light remains on after the reset
switch has been pushed, have the tire
pressure warning system checked at your
Scion dealer.
If you have a flat tire, replace it with the
spare tire. For details, see “If you have
a flat tire” on page 172.
If the warning light blinks once every
second:
The low tire pressure warning system may
be malfunctioning. Contact your Scion
dealer.
If the warning light blinks twice every
second:
The low tire pressure warning system
needs to be initialized. Reset the system
with the tire pressure warning system re-
set switch. (To reset the system, see
“TIRE PRESSURE WARNING SYSTEM
RESET SWITCH”.) The tire pressure warning system does
not function properly under certain cir-
cumstances. In the following cases, the
low tire pressure warning light may not
come on even if the tire inflation pres-
sure is low, or it may come on when
the tire inflation pressure is actually
normal.
A compact spare tire, snow tires, or
tire chains are used.
The tire inflation pressure is excessive-
ly higher than specified, or tire inflation
pressure suddenly drops due to burst-
ing or other causes.
The vehicle is driven on a slippery
road surface such as rough or frozen
roads.
The vehicle speed is less than 30 km/h
(19 mph) or more than 100 km/h (62
mph), and the driving duration is less
than 5 minutes.
The tires differ in tread pattern or
manufacturer.
The tires are not the specified size.
The tread wear is very different among
the installed tires.
Rapid acceleration/deceleration or
sharp turns is continued.

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.

1. Get the required tools and spare
tire.
1. Wheel nut wrench
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 128.
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.

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.

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.
Page 186 of 254

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.
