Installation of a mobiletwo–way radio system
As the installation of a mobile two–way radio system in
your vehicle could affect electronic systems such as
multiport fuel injection system/sequential multiport fuel
injection system, cruise control system, anti–lock brake
system, SRS airbag system and seat belt pretensioner
system, be sure to check with your Scion dealer for
precautionary measures or special instructions regarding
installation.
Tires and loading on your Scion
Underinflated or overinflated tire inflation pressure
and the excess load may result in the deterioration
of steering ability and braking ability, leading to
an accident. Check the tire inflation pressure peri-
odically and be sure to keep the load limits given
in this Owner ’s Manual. For details about tire infla-
tion pressure and load limits, see page 237 and
page 174.

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.)

121
As an added safety feature, your ve-
hicle has been equipped with a tire
pressure monitoring system (TPMS–
tire pressure warning system) that il-
luminates a low tire pressure telltale
(tire pressure warning light) when one
or more of your tires is significantly
underinflated. Accordingly, when the
low tire pressure telltale (tire pres-
sure warning light) illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure. Driving on a sig-
nificantly underinflated tire causes
the tire to overheat and can lead to
tire failure. Underinflation also re-
duces fuel efficiency and tire tread
life, and may affect the vehicle’s han-
dling and stopping ability.
Please note that the TPMS (tire pres-
sure warning system) is not a substi-
tute for proper tire maintenance, and
it is the driver ’s responsibility to
maintain correct tire pressure, even if
underinflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale (tire
pressure warning light).Your vehicle has also been equipped
with a TPMS (tire pressure warning
system) malfunction indicator to indi-
cate when the system is not operat-
ing properly. The TPMS (tire pressure
warning system) malfunction indicator
is combined with the low tire pres-
sure telltale (tire pressure warning
light). When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated. This
sequence will continue upon subse-
quent vehicle startups as long as
the malfunction exists. When the mal-
function indicator is illuminated, the
system may not be able to detect or
signal low tire pressure as intended.TPMS (tire pressure warning system)
malfunction may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS (tire pressure warning sys-
tem) from functioning properly. Al-
ways check the TPMS (tire pressure
warning system) malfunction telltale
after replacing one or more tires or
wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS (tire pressure
warning system) to continue to func-
tion properly.

122
NOTICE
Do not use liquid sealants for a flat
tire as tire pressure warning valve
and transmitter will be damaged.
 When the tires must be repaired or
replaced, have them repaired or re-
placed by the nearest Scion dealer
or an authorized tire dealer. The
tire pressure warning valves and
transmitters will be affected by the
installation or removal of tires.

IF THE TIRE PRESSURE WARNING
LIGHT COMES ON AFTER BLINKING
FOR 1 MINUTE...
If the tire pressure warning light comes
on after blinking for 1 minute when the
ignition key is turned to the “ON” posi-
tion, the tire pressure warning system
is not working properly.
The system will be disabled in the follow-
ing conditions:
(When the condition becomes normal, the
system will work properly.)
If tires not equipped with tire pressure
warning valves and transmitters are
used.
If the ID code on the tire pressure
warning valves and transmitters is not
registered on the tire pressure warning
computer.
If the tire inflation pressure is more
than 500 kPa (5.1 kgf/cm2 or bar, 73
psi) or higher.
The system may be disabled in the follow-
ing conditions:
(When the condition becomes normal, the
system will work properly.)
If electronic devices or facilities using
similar radio wave frequencies are
nearby.
If a radio set at similar frequencies is
in use in the vehicle.
If a window tint that affects the radio
wave signals is installed.
If there is a lot of snow or ice on the
vehicle, in particular around the wheels
or wheel housings.
If non −genuine Scion wheels are used.
If tire chains are used.
If the tire pressure warning light continues
to come on after blinking for 1 minute
when the ignition key is turned to the
“ON” position, have the system checked
by your Scion dealer.

123
Even if you use genuine wheels, the tire
pressure warning system may not work
properly with some types of tires.
Pushing the tire pressure warning reset
switch should not turn off the tire pressure
warning light.

REPLACING TIRES AND WHEELS
When replacing the tires and wheels, be
sure to install tire pressure warning valves
and transmitters. ID codes on the tire
pressure warning valves and transmitters
are registered in the tire pressure warning
computer. When replacing a tire pressure
warning valve and transmitter, it is neces-
sary to register the ID code of tire pres-
sure warning valve and transmitter. Have
the ID code registered by your Scion deal-
er.
If the ID code is not registered, the sys-
tem will not work properly. After about 20
minutes, the tire pressure warning light
comes on after blinking for 1 minute to
indicate a system malfunction.
NOTICE
When the tires or tire pressure warn-
ing valves and transmitters must be
replaced, have them replaced by your
Scion dealer. The tire pressure warn-
ing valves and transmitters will be
affected by the installation or removal
of tires.
Tire pressure warning reset switch

When initializing the system, the present
tire inflation pressure is stored as stan-
dard. The tire pressure warning system
determines decreased air pressure by
comparing the present and the standard
tire inflation pressures. When you change
the set tire inflation pressure, it is neces-
sary to initialize the tire pressure warning
system.
When rotating the tires on vehicles dif-
fering with front and rear tire inflation
pressures.To initialize the system, perform the fol-
lowing:
1. Park the vehicle in a safe place and turn the ignition key to the “ACC” or
“LOCK” position.
2. Adjust the pressure of all the installed tires to the specified cold tire inflation
pressure level. (See “Tires” on page
261.)
3. Turn the ignition key to the “ON” posi- tion.
4. Open the glove box, and push and hold the tire pressure warning reset
switch until the tire pressure warning
light blinks slowly three times.
5. Wait for a few minutes with the ignition key in “ON” position, and then turn the
ignition key to the “ACC” or “LOCK”
position.
If you push the tire pressure reset switch
while the vehicle is moving, initialization is
not performed.
If you push the tire pressure reset switch
accidentally and initialization is performed,
adjust the tire inflation pressure to the
specified level and initialize the system
again.

Anti–lock brake system is not de-
signed to shorten the stopping dis-
tance: Always drive at a moderate
speed and maintain a safe distance
from the vehicle in front of you.
Compared with vehicles without an
anti–lock brake system, your vehicle
may require a longer stopping dis-
tance in the following cases:
Driving on rough, gravel or
snow–covered roads.
Driving with tire chains installed.
Driving over the steps such as the
joints on the road.
Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The anti–lock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels’ turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed
resulting in a longer stopping dis-
tance.
“ABS” warning light
This light comes on when the ignition
key is turned to the “ON” position. If
the anti–lock brake system works prop-
erly, the light turns off after a few sec-
onds. Thereafter, if the system malfunc-
tions, the light comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti–lock brake system does not operate,
but the brake system still operates con-
ventionally. When the “ABS” warning light is on (and
the brake system warning light is off), the
anti–lock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.
If any of the following conditions oc-
curs, this indicates a malfunction some-
where in the components monitored by
the warning light system. Contact your
Scion dealer as soon as possible to
service the vehicle.
When the ignition key is turned to the
“ON” position, the light does not come
on or remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
