iv
In order to be effective, the SRS airbags must deploy
with tremendous speed. The rapid deployment of the
SRS airbags makes the SRS airbags themselves poten-
tial sources of serious injury if an occupant is too close
to an airbag, or if an object or some part of his or her
body has been placed between the occupant and the
airbag at the time of deployment. This is just one exam-
ple of how the instructions in Section 1–3 of this Own-
er ’s Manual will help ensure proper use of the occupant
restraint systems, and increase the safety they can pro-
vide to you and your family in the event of an accident.
Scion recommends you to read the provisions in Section
1–3 carefully and refer to them as needed during your
time of ownership of this vehicle.Event data recorder
Your vehicle has computers that monitor and control
certain aspects of your vehicle. These computers assist
in driving and maintaining optimal vehicle performance.
Besides storing data useful for troubleshooting, there is
a system to record data in a crash or a near car crash
event. This is called an Event Data Recorder (EDR).
The SRS airbag sensor assembly contains the EDR. In
a crash or a near car crash event, this device may
record some or all of the following information:
Engine speed
Whether the brake pedal was applied or not
Vehicle speed
To what extent the accelerator pedal was depressed
Position of the transmission selector lever
Whether the driver and front passenger wore the
seat belts or not
Driver ’s seat position
Front passenger ’s occupant classification

(a) Brake System Warning Light
This light comes on in the following cases
when the ignition key is in the “ON” posi-
tion.
When the parking brake is applied...
The light comes on for a few seconds
when the ignition key is turned to the
“ON” position even after the parking brake
is released.
When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
Have your vehicle checked at your
Scion dealer in the following cases:
The light does not come on even if the
parking brake is applied when the igni-
tion key is in the “ON” position.
The light does not come on even if the
ignition key is turned to the “ON” posi-
tion with the parking brake released.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If either of the following conditions
occurs, immediately stop your vehicle
at a safe place and contact your
Scion dealer.
The light does not turn off even
after the parking brake is released
while the engine is running.
In this case, the brakes may not
work properly and your stopping
distance will become longer. De-
press the brake pedal firmly and
bring the vehicle to an immediate
stop.
The brake system warning light re-
mains on together with the “ABS”
warning light.
In this case, not only the anti–lock
brake system will fail but also the
vehicle will become extremely un-
stable during braking.
(b) Driver’s Seat Belt Reminder Light
and Buzzer
The light and buzzer act as a reminder to
have the driver buckle up the seat belt.
Once the ignition key is turned to “ON” or
“START” position, the reminder light
flashes and the buzzer sounds if the driv-
er ’s seat belt is not fastened. Unless the
driver fastens the belt, the light continues
flashing and 5 beeps sound.
(c) Front Passenger ’s Seat Belt
Reminder Light
The light acts as a reminder to have the
front passenger buckle up the seat belt.
Once the ignition key is turned to “ON” or
“START” position, the reminder light
flashes if a passenger sits in the front
passenger seat and does not fasten the
seat belt. However, if a front passenger
uses an additional seat cushion, the light
may not flash even when the seat belt is
not buckled up.
If luggage or other load is placed on the
front passenger seat, depending on its
weight and how it is placed on the seat,
built–in sensors in the seat cushion may
detect the pressure, causing the reminder
light to flash.

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,
“AIRBAG ON” indicator light, “AIRBAG
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.The SRS warning light and “AIRBAG OFF”
indicator light will come on if there is a
malfunction in the front passenger occu-
pant 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 flashes in the fol-
lowing cases when the ignition key 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...
If initialization is completed, the light
blinks three times.
When the system malfunctions...
If the system malfunctions, the light

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.
