Do not disassemble or repair the
front and rear pillars and roof side
rails containing the curtain shield
airbags. Such changes may disable
the system or cause the curtain
shield airbags to inflate accidental-
ly, resulting in death or serious in-
jury.
Failure to follow these instructions
can result in death or serious injury.
Consult your Scion dealer about any
repair and modification.NOTICE
Do not perform any of the following
changes without consulting your
Scion dealer. Such changes can
interfere with proper operation of the
SRS side airbag and curtain shield
airbag system in some cases.
 Installation of electronic devices
such as a mobile twoway radio,
cassette tape player or compact
disc player
 Modification of the suspension sys-
tem
 Modification of the side structure of
the passenger compartment
 Repairs made on or near the con-
sole or front seat

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 side airbags and curtain
shield airbags are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors, driv-
er ’s seat position sensor, driver ’s seat belt
buckle switch, passenger ’s seat belt
buckle switch, seat belt pretensioner as-
semblies, inflators, warning light, intercon-
necting wiring and power sources. (For
details, see “Service reminder indicators
and warning buzzers” on page 83.)

(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 increase. Depress the
brake pedal firmly and bring the ve-
hicle to an immediate stop.
The brake system warning light re-
mains on together with the “ABS”
warning light.
In this case, not only the antilock
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
buckle up the driver’s seat belt.
Once the ignition key is turned to the
“ON” or “START” position, the reminder
light flashes and the buzzer sounds if the
driver ’s seat belt is not fastened. Unless
the driver fastens the belt, the light con-
tinues flashing and the buzzer sounds for
about 5 seconds.
(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 the
“ON” or “START” position, the reminder
light flashes if a passenger sits in the
front passenger seat and does not fasten
the seat belt. Unless the front passenger
fastens the belt, the light continues flash-
ing.
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.

89
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.
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 antilock
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 light will come on when the igni-
tion key is turned to the “ON” position.
After about 6 seconds, the light will go
off. This means the systems of the air-
bags and seat belt pretensioners are
operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors, driv-
er ’s seat position sensor, driver ’s seat belt
buckle switch, passenger ’s seat belt
buckle switch, seat belt pretensioner as-
semblies, inflators, warning light, intercon-
necting wiring and power sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere 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 for more than 6
seconds or flashes.
The light comes on or starts flashing
while driving.
(l) High Engine Coolant Temperature
Warning Light
The high engine coolant temperature warn-
ing light (red) will come on when the igni-
tion key is turned to the “ON” position.
After a few seconds, the light will go off.
If your engine coolant temperature is cool
with the ignition switch on, the low engine
coolant temperature indicator light (blue)
comes on. If it keeps lighting on with the
engine fully warmed, contact your Scion
dealer as soon as possible to service the
vehicle.
If the high engine coolant temperature
warning light (red) flashes, your engine is
too hot. If your vehicle overheats, stop
your vehicle and allow the engine to cool.
Your vehicle may overheat during severe
operating conditions, such as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.
Idling for a long period with the air
conditioning on in stop −and− go traffic.

CAUTION
Do not overestimate the antilock
brake system: Although the antilock
brake system assists in providing ve-
hicle control, it is still important to
drive with all due care and maintain
a moderate speed and safe distance
from the vehicle in front of you, be-
cause there are limits to the vehicle
stability and effectiveness of steering
wheel operation even with the anti
lock brake system on.
If tire grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the antilock brake system does not
provide vehicle control.
Antilock 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
antilock 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 antilock
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
Vehicles with vehicle stability control sys-
tem—
The light comes on when the ignition key
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.
