2007 TOYOTA AVALON brake sensor

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 potential sources of
death or 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 example of how the instruc-
tions in Section 1−3 of this Owner’s Manual will help ensure
proper use of the occupant restraint systems, and increase
the safety they can provide to you and your family in the
event of an accident.
Toyota 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

The automatic light control sensor is on
the top of the center instrument panel.
Do not place anything on the instrument
panel, and/or do not affix anything on the
windshield to block this sensor.
If you feel that the automatic light control
comes into operation too early or too late,
have the sensor adjusted by your Toyota
dealer.
Automatic light cut off system
Position 1 or position 3 with the tail
lights on—
The lights automatically turn off when the
driver ’s door is opened with the engine
off.Position 2 or position 3 with the head-
lights on—
The lights automatically turn off after 30
seconds when any of the door or trunk lid
is opened and closed with the engine off.
The lights can be turned off immediately
by pushing the lock switch on the wireless
remote control transmitter with all the
doors locked and the trunk lid closed.
If any of the door or trunk lid is kept
opened, the lights automatically turn off
after 20 minutes.
To turn on the lights again, turn the igni-
tion switch is set at ON or actuate the
headlight switch. If you are going to park
for over one week, make sure the head-
light switch is off.
NOTICE
To prevent the battery from being dis-
charged, do not leave the lights on
for a long period when the engine is
not running.
Daytime Running Light (DRL) system
The headlights turn on when the parking
brake is released with the engine started,
even with the light switch in the “OFF”
position. They will not go off until the
ignition switch is turned off.
To turn on the other exterior lights and
instrument panel lights, twist the knob to
position 1.
Twist the knob to the position 2 to turn
the headlights to full intensity for night
driving.

If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the components 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 switch is set at 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.
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
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 and Buzz- er
This light remains on until all the doors
are completely closed.
The buzzer also sounds once when any
of the doors is not completely closed at
the vehicle speed 5 km/h (3 mph) or
more. Stop the vehicle and close the door
completely.
(j) SRS Warning Light
This indicator comes on when the igni-
tion switch is set at ON. It goes off
after about 6 seconds. This means the
SRS airbags 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, front passenger occupant
classification system, “AIRBAG ON” indi-
cator light, “AIRBAG OFF” indicator light,
front 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
Toyota dealer as soon as possible.
The light does not come on when the
ignition switch is set at ON or remains
on for more than 6 seconds.
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.

This system operates by detecting pri-
marily the reflectors of the vehicle
ahead. The distance may not be accu-
rately or absolutely detected in the fol-
lowing cases:
The vehicle ahead has higher ground
clearance, which means that the
placement of the reflectors is in a
higher position.
The rear section of the vehicle ahead
is extremely dirty.
The vehicle ahead or other vehicles
around you are flinging up water or
snow.
Excessive exhaust gas (black smoke)
is coming from the vehicle ahead or
other vehicles around you, obscuring
your front view.
There is an obstruction (protective
film, sticker, etc.) on the reflectors
on the vehicle ahead, or reflectors
are not installed on the vehicle
ahead or are damaged.
Heavy luggage in the luggage
compartment or rear seats is caus-
ing the nose of your vehicle to tilt
up.
CAUTION
To avoid accidents, always keep the
laser radar sensor glass clean and
never allow it to be covered with
icicle or any substance, so it can de-
tect the vehicle in front. (See “LASER
RADAR SENSOR” on page 189.)
CAUTION
Do not rely excessively on dynamic
laser cruise control. Observe the fol-
lowing precautions in order to avoid
serious injury or death:
Under certain conditions where the
vehicle in front slows drastically, or
is stopped, the dynamic laser cruise
control will neither warn you nor
decelerate. You must depress the
brake pedal to slow down, ensuring
collision avoidance or that suffi-
cient vehicletovehicle distance is
maintained.
Do not use dynamic laser cruise
control in the following conditions:
In bad weather (such as rain, fog,
snow, sandstorms or direct sun-
light, or when raindrops or snow-
flakes get on the laser radar sensor
glass), the vehicletovehicle dis-
tance will not be measured accura-
tely.
When using the windshield wipers
at high or low speeds the dynamic
laser radar cruise control turns off.

189
CAUTION
If the display flashes and beeps,
you must depress the brake pedal
to slow down to avoid a collision
or maintain sufficient vehicletove-
hicle distance.
In the following conditions, the ap-
proach warning may not turn on
even if the vehicle drives closer to
the vehicle ahead, and an accident
may occur:
Your vehicle and the vehicle ahead
are cruising at almost the same
speed.
The vehicle ahead is cruising at a
faster speed than yours. (The dis-
tance between the vehicles will be-
come longer.)
The vehicle ahead is at a stop or
driving very slowly. Pay special
attention to a very slow vehicle at
the end of the line in heavy traffic
or at a tollgate.
The speed has just been set.
The accelerator pedal is depressed
or has just been released.
LASER RADAR SENSOR
The laser radar sensor is used for ve-
hicletovehicle distance control cruis-
ing.
If dirt is on the sensor glass, the
dynamic laser cruise control function is
automatically cancelled and a warning
code appears on the display. (See
“VEHICLETOVEHICLE DISTANCE
CONTROL MODE FAILURE WARNING”
described below.)
However, if the glass sensor is covered
with icicle or any substance, dirt may
not be detected.Before driving in the vehicletovehicle
distance control mode, make sure the
radar sensor glass is clean.
This product is a class I laser product
complied with 21 C.F.R part 1040.10
and 1040.11.
CAUTION
To ensure that dynamic laser cruise
control will function properly while
driving, observe the following:
Always keep the laser radar sensor
glass clean. When cleaning, use a
soft cloth and be careful not to
damage the sensor.
Avoid strong impacts around the la-
ser radar sensor. An incorrect laser
radar sensor alignment will result in
system malfunction. A special de-
vice is required to adjust the laser
radar sensor alignment. Be sure to
have the sensor adjusted by your
Toyota dealer.
Do not affix a sticker (including a
transparent sticker) or attach an ac-
cessory around the laser radar sen-
sor.

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 without the vehicle stability
control system—
The light comes on when the ignition
switch is set at ON. If the anti −lock brake
system works properly, the light turns off
after a few seconds. Thereafter, 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
a sudden braking or braking on slippery
road surfaces.
