brake sensor TOYOTA xA 2006 Owners Manual (in English)

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 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 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 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.

94
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 ve-
hicle will become extremely unstable
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, side and
curtain shield airbags and seat belt pre-
tensioners are operating properly.
This warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors,
driver ’s seat position sensor, driver ’s seat
belt buckle switch, front passenger occu-
pant classification system, “AIRBAG ON”
indicator light, “AIRBAG OFF” indicator
light, passenger ’s seat belt buckle switch,
seat belt pretensioner assemblies, inflat-
ors, interconnecting 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.
The light comes on or starts flashing
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) High Engine Coolant Temperature
Warning Light
When the ignition key is turned to the
“ON” position, the engine coolant tempera-
ture warning light (red) will come on for
a few seconds. If the engine coolant tem-
perature is low, the warning light will then
change from red to blue, and turn off
when the engine is fully warmed. If it
stays on even after the engine is fully
warmed, contact your Scion dealer as
soon as possible to service the vehicle.
If the engine coolant temperature warning
light (red) flashes, the engine is too hot.
If your vehicle overheats, stop your ve-
hicle 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.

131
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
This light comes on when the ignition key
is turned to the “ON” position. If the anti −
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.
