Installation of a mobiletwoway 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, anti −lock brake system, traction control
system, vehicle stability control system, SRS airbag sys-
tem 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 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 periodi-
cally and be sure to keep the load limits given in
this Owner ’s Manual. For details about tire inflation
pressure and load limits, see page 243 and pages
179 through 180.

If the fuel tank is not empty or the fuel
tank cap is not loose...
There is a problem somewhere in the
engine, emission control system, auto-
matic transmission electrical system or
warning light system itself.
Contact your Scion dealer as soon as
possible to service the vehicle.
Emissions Inspection and Maintenance
(I/M) programs
Your vehicle may not pass a state emis-
sion inspection if the malfunction indicator
lamp remains on. Contact your Scion deal-
er to check your vehicle’s emission control
system and OBD (On −Board Diagnostics)
system before taking your vehicle for the
inspection.
For details, see “Emissions inspection and
maintenance (I/M) programs” on page 230.
(g) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes very low. Fill up the
tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual. (h) Low Engine Oil Pressure Warning
Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Scion dealer or qualified repair shop for
assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.
(i) “ABS” Warning Light
The light comes on when the engine
switch is turned to the “ON” position. If
the anti −lock brake system and the brake
assist system work properly, the light
turns off after a few seconds. Thereafter,
if the systems malfunction, 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, the brake assist
system, the traction control system and
the vehicle stability control system do not
operate, but the brake system still oper-
ates conventionally.
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 either of the following conditions
occurs, this indicates a malfunction
somewhere in the components moni-
tored by the warning light system.
Contact your Scion dealer as soon as
possible to service the vehicle.

105
If the following conditions occur, this
indicates a malfunction somewhere in
the components monitored by the warn-
ing light system. Contact your Scion
dealer as soon as possible to service

position or remains on.
The light stays on while you are driv-
ing.
CAUTION
If the electric power steering system
warning light comes on, take your ve-
hicle to Scion dealer as soon as pos-
sible. In this case, more effort is re-
quired for the steering wheel to turn
than usual. Drive your vehicle while
firmly gripping the steering wheel.
(m) “VSC OFF” Warning Light
The light warns that there is a problem
somewhere in the vehicle stability control
system or traction control system.
The light will come on when the engine
switch is turned to the “ON” position, and
will go off after a few seconds.
If the light comes on while you are driv-
ing, the vehicle stability control system
and/or traction control system do not
work. However, as conventional braking
operates when applied, there is no prob-
lem to continue your driving.
In the following cases, contact your Scion
dealer:
When the engine switch is turned to
the “ON” position, the light does not
come on or remains on.
The light comes on while you are driv-
ing.(n) Tire Pressure Warning Light
This light comes on when the engine
switch is turned to the “ON” position. If
the tire pressure warning system works
properly and tire inflation pressure is ap-
propriate, the light goes off after a few
seconds.
This light comes on or flashes in the fol-
lowing cases when the engine switch is
turned to the “ON” position.
When the low tire inflation pressure
is detected while driving...
If any tire has low inflation pressure,
the light comes on.
The light goes off after the tire inflation
pressure is adjusted to a specified lev-
el.
When initializing the system...
When ready to be initialized, the light
blinks three times.
When the system malfunctions...
If the system malfunctions, the light
comes on after blinking for 1 minute.

The traction control system automatical-
ly helps prevent the spinning of front
wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the engine switch is turned to “ON”
position, the system automatically turns
on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power against front wheels cannot be
maintained, even though the traction
control system is in operation. Do not
drive the vehicle under any speed or
maneuvering conditions which may
cause the vehicle to lose traction
control. In situations where the road
surface is covered with ice or snow,
your vehicle should be fitted with
snow tires or tire chains. Always
drive at an appropriate and cautious
speed for the present road condi-
tions.
NORMAL DRIVING MODE
Leave the system on during the ordi-
nary driving so that it can operate
when needed.
You may hear a sound in the engine
compartment for a few seconds just after
the vehicle begins to move. This means
that the traction control system is in the
self−check mode, but does not indicate a
malfunction. When the traction control system is oper-
ating, the following conditions occur:
The system controls the spinning of the
front wheels. At this time, the slip indi-
cator light blinks.
You may feel vibration or noise in your
vehicle, caused by operation of the
brakes. This indicates the system is
functioning properly.
The slip indicator light comes on for a few
seconds when the engine switch is turned
to “ON” position. If the indicator light does
not come on when the engine switch is
turned on, contact your Scion dealer.

TRACTION CONTROL OFF MODE
If your wheels get stuck in a ditch
when you are driving on a severe off
road and sand, turn off the traction
control system or vehicle stability con-
trol system. (See page 117 to turn off
the vehicle stability control system.)
These systems control engine perfor-
mance that interferes with the process
of freeing your wheels.
To turn off: Push “VSC OFF” switch
briefly.
The slip indicator light will come on.
When the engine switch is turned to “ON”
position, the traction control system and
vehicle stability control system always turn
on.
Traction control system turns back on
when the vehicle reaches to the certain
speed.
To turn on: Push “VSC OFF” switch
once again.
The slip indicator light will go off.
CAUTION
When traction control and vehicle sta-
bility control system are off, be espe-
cially careful and drive at a speed
appropriate to the road conditions. As
these are systems to ensure vehicle
stability and driving force, do not
turn off traction control and vehicle
stability control system unless neces-
sary.
In the following cases, contact your Scion
dealer:
The slip indicator light does not come
on when the engine switch is turned to
“ON” position.
The slip indicator light remains on after
the engine switch is turned to “ON”
position.
The slip indicator light comes on in the
normal driving mode while driving.

11 6
The vehicle stability control system
helps provide integrated control of the
systems such as an antilock brake
system, traction control, engine control,
etc. This system automatically controls
the brakes and engine to help prevent
the vehicle from skidding when corner-
ing on a slippery road surface or oper-
ating steering wheel abruptly.
The vehicle stability control system is acti-
vated when the vehicle speed is about
more than 15 km/h (9 mph).
You may hear a sound in the engine
compartment for a few seconds just after
the vehicle begins to move. This means
that the system is in the self−check mode,
but does not indicate a malfunction.CAUTION
Do not rely excessively on the ve-
hicle stability control system. Even
if the vehicle stability control sys-
tem is operating, you must always
drive carefully and attentively. Reck-
less driving will result in an acci-
dent and cause death or serious
injury. If the slip indicator light
flashes, sounding an alarm, special
care should be taken while driving.
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle stability control
system may not function correctly.
When replacing the tires or wheels,
contact your Scion dealer. (See
“Checking and replacing tires” on
page 246.)
In situations where the road surface
is covered with ice or snow, your
vehicle should be fitted with snow
tires or tire chains.
If the vehicle is going to skid during driv-
ing, the slip indicator light blinks and an
alarm sounds intermittently. Special care
should be taken while driving.
The slip indicator light comes on for a few
seconds when the engine switch is turned
to “ON” position. If the indicator light does
not come on when the engine switch is
turned on, contact your Scion dealer.

VEHICLE STABILITY CONTROL OFF
MODE
If your wheels get stuck in a ditch
when you are driving on a severe off
road and sand, turn off the traction
control system or vehicle stability con-
trol system. (See page 115 to turn off
the traction control system). These sys-
tems control engine performance that
interferes with the process of freeing
your wheels.
To turn off: Push and hold the “VSC
OFF” switch for 3 seconds when the
vehicle is not moving.
The slip indicator light and “VSC OFF”
indicator light will come on.
When the engine switch is turned to “ON”
position, the traction control system and
vehicle stability control system always turn
on.
To turn on: Push “VSC OFF” switch
once again.
The slip indicator light and “VSC OFF”
indicator light will go off.
CAUTION
When traction control and vehicle sta-
bility control system are off, be espe-
cially careful and drive at a speed
appropriate to the road conditions. As
these are systems to ensure vehicle
stability and driving force, do not
turn off traction control and vehicle
stability control system unless neces-
sary.
In the following cases, contact your Scion
dealer:
The slip indicator light and “VSC OFF”
indicator light do not come on when the
engine switch is turned to “ON” position.
The slip indicator light or “VSC OFF”
indicator light remains on after the en-
gine switch is turned to “ON” position
.
The slip indicator light or “VSC OFF”
indicator light come on in the normal
driving mode while driving.

“ABS” warning light
This light comes on when the engine
switch is turned to the “ON” position.
If the antilock brake system works
properly, the light turns off after a few
seconds. Thereafter, if the system mal-
functions, 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, the brake assist
system, the traction control system and
the vehicle stability control system do not
operate, but the brake system still oper-
ates conventionally. 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 either 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 engine switch 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.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Scion dealer.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.

—Uniform tire quality grading
This information has been prepared
in accordance with regulations issued
by the National Highway Traffic Safe-
ty Administration of the U.S. Depart-
ment of Transportation. It provides
the purchasers and/or prospective
purchasers of Scion vehicles with in-
formation on uniform tire quality grad-
ing.
Your Scion dealer will help answer
any questions you may have as you
read this information.
DOT quality grades—All passenger
vehicle tires must conform to Fed-
eral Safety Requirements in addi-
tion to these grades. Quality
grades can be found where appli-
cable on the tire sidewall between
tread shoulder and maximum sec-
tion width.
For example:
Treadwear 200 Traction AA
Temperature ATreadwear—
The treadwear grade is
a comparative rating based on the
wear rate of the tire when tested un-
der controlled conditions on a speci-
fied government test course. For ex-
ample, a tire graded 150 would wear
one and a half (1 −1/2) times as well
on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual
conditions of their use, however, and
may depart significantly from the
norm due to variations in driving hab-
its, service practices and differences
in road characteristics and climate. Traction AA, A, B, C—
The traction
grades, from highest to lowest, are
AA, A, B, and C, and they represent
the tire’s ability to stop on wet pave-
ment as measured under controlled
conditions on specified government
test surfaces of asphalt and concrete.
A tire marked C may have poor trac-
tion performance.
Warning: The traction grade assigned
to this tire is based on braking
(straight ahead) traction tests and
does not include cornering (turning)
traction.
