brake sensor TOYOTA YARIS 2007 2.G Owners Manual

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.
Toyota recommends you to read the provisions in Sec-
tion 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

CAUTION
If the “ABS” warning light remains on
together with the brake system
warning light, immediately stop your
vehicle at a safe place and contact
your Toyota dealer.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
(i) Open Door Warning Light
This light remains on until all the side
doors and back door are completely
closed.
(j) Electric Power Steering SystemWarning Light
The light comes on when the ignition key
is turned to the “ON” position. If the elec-
tric power steering system warning light
works properly, the light turns off after a
few seconds. If the system has malfunc-
tions, the light comes on again. If the following conditions occur, this
indicates a malfunction somewhere in
the parts monitored by the warning
light system. Contact your Toyota deal-
er 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 stays on while you are driv-
ing.
The warning light turning on while racing
the engine for a long time may not indi-
cate malfunction. To turn off the light, re-
start the engine and start driving.
CAUTION
If the electric power steering system
warning light comes on, take your ve-
hicle to Toyota dealer as soon as
possible. In this case, more effort is
required for the steering wheel to
turn than usual. Drive your vehicle
while firmly gripping the steering
wheel.
(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 system of the air-
bags and front seat belt pretensioners
are operating properly.
The 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, front passenger ’s seat belt buckle
switch, seat belt pretensioner assemblies,
inflators, interconnecting wiring and power
sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota 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.

When the antilock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
You may hear the anti−lock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the ve-
hicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.
At the end of the anti −lock brake sys-
tem activation, the brake pedal may
move a little forward.
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 tire 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.
