109
If the system fails to reset, the light will
remain on or keep flashing.
(f) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the “ON” position and
goes off after the engine starts. This
means that the warning light system is
operating properly.
If the lamp remains on or the lamp
comes on while driving, first check the
following.
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
after taking several driving trips.
If the lamp will not go off even after
the several trips, contact your Scion
dealer as soon as possible. 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 Di agnostics)
system before taking your vehicle for the
inspection.
For details, see “Emissions inspection and
maintenance (I/M) programs” on page 222.
(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 ignition key
is turned to the “ON” position. If the an-
ti–lock brake system works properly, the
light turns off after a few seconds. There-
after, if the system malfunctions, 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
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.The light does not come on when the
ignition key is turned to the “ON” posi-
tion, 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 anti–lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
(j) Open Door Warning Light
This light remains on until all the side
doors and back door are completely
closed. (k) SRS Warning Light
This indicator comes on when the igni-
tion key is turned to the “ON” position.
It goes off after about 6 seconds. This
means the SRS front airbags, SRS side
airbags, curtain shield airbags and seat
belt pretensioners are operating proper-
ly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sensor
assemblies, curtain shield airbag sensor
assemblies, driver ’s seat position sensor,
driver’s seat belt buckle switch, front pas-
senger occupant classification system,
“AIR BAG ON” indicator light, “AIR BAG
OFF” indicator light, front passenger ’s seat
belt buckle switch, seat belt pretensioner
assemblies, inflators, warning light, inter-
connecting wiring and power sources.
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Scion dealer as soon as possible.
When the ignition key is turned to the
“ON” position, the light does not come
on or remains on for more than 6 sec-
onds.
The light comes on while driving.

111
The SRS warning light and “AIR BAG
OFF” indicator light will come on if there
is a malfunction in the front passenger
occupant classification system.
(l) Tire Pressure Warning Light
This light comes on when the ignition key
is turned to the “ON” position. If the tire
pressure warning system works properly
and tire inflation pressure is appropriate,
the light goes off after a few seconds.
This light comes on or comes on after
blinking for 1 minute in the following
cases when the ignition key is turned to
the “ON” position.
When the 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...
If initialization is accepted, the light
blinks slowly three times.
When the system malfunctions...
If the system malfunctions, the light
comes on after blinking for 1 minute.Although it is no problem to continue
driving, have your vehicle checked by
your Scion dealer as soon as possible.
(m) Key Reminder Buzzer
This buzzer acts as a reminder to remove
the key when you open the driver’s door
with the ignition key in the “ACC” or
“LOCK” position. CHECKING SERVICE REMINDER
INDICATORS (except the low fuel level
warning light)
1. Apply the parking brake.
2. Open either side door or back door. The open door warning light should
come on.
3. Close the door. The open door warning light should go
off.
4. Turn the ignition key to the “ON” posi- tion, but do not start the engine.
All the service reminder indicators except
the open door warning light should come
on. The “ABS” warning light, “MAINT
REQD” reminder light and tire pressure
warning light go off after a few seconds.
The SRS warning light goes off after
about 6 seconds.
If any service reminder indicator or warn-
ing buzzer does not function as described
above, have it checked by your Scion
dealer as soon as possible.

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.

—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 A Treadwear—
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.

When encountering flooded roads
Do not drive on a road that has flooded
after heavy rain etc. Doing so may cause
serious damage to the vehicle.
NOTICE
Driving on a flooded road may cause
the engine to stall as well as cause
serious vehicle malfunctions such as
shorts in electrical components and
engine damage from water immersion.
In the event that you drive on a
flooded road and the vehicle is
flooded, be sure to have your Scion
dealer check brake function, changes
in quantity and quality of engine oil,
transaxle fluid, etc. and lubricant con-
dition for the bearings and suspen-
sion joints (where possible) and the
function of all joints and bearings.
Winter driving tips
Make sure you have a proper freeze
protection for engine coolant.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non–silicate, non–amine, non–nitrite,
and non–borate coolant with long–life
hybrid organic acid technology. (Coolant
with long–life hybrid organic acid
technology is a combination of low
phosphates and organic acids.)
See “Checking the engine coolant level”
on page 234 for details of coolant type
selection.
“Toyota Super Long Life Coolant” is a
mixture of 50% coolant and 50% deionized
water. This coolant provides protection
down to about –35C (–31 F).
NOTICE
Do not use plain water alone.
Check the condition of the battery and
cables.
Cold temperatures reduce the capacity of
any battery, so it must be in top shape
to provide enough power for winter start-
ing. Section 7–3 tells you how to visually
inspect the battery. Your Scion dealer and
most service stations will be pleased to
check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 233 for recommended viscosity.
Leaving a heavy summer oil in your ve-
hicle during winter months may cause
harder starting. If you are not sure about
which oil to use, call your Scion deal-
er—they will be pleased to help.
Keep the door locks from freezing.
Squirt lock de–icer or glycerine into the
locks to keep them from freezing. To open
a frozen lock, try heating the key before
inserting it.
