2011 TOYOTA MATRIX sensor

50 1-3. Adjustable components (seats, mirrors, steering wheel)
CAUTION
■Seat belt pretensioners
●Do not place anything, such as a cushion, on the front passenger's seat.
Doing so will disperse the passenger's weight, which prevents the sensor
from detecting the passenger's weight properly. As a result, the seat belt
pretensioner for the front passenger's seat may not activate in the event of
a collision.
●If the pretensioner has activated, the SRS warning light will come on. In
that case, the seat belt cannot be used again and must be replaced at
your Toyota dealer.
■Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate, or buckle to be
jammed in the door.
●Inspect the seat belt system periodically. Check for cuts, fraying, and loose
parts. Do not use a damaged seat belt until it is replaced. Damaged seat
belts cannot protect an occupant from death or serious injury.
●Ensure that the belt and tab are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact your Toyota
dealer.
●Replace the seat assembly, including the belts, if your vehicle has been
involved in a serious accident, even if there is no obvious damage.
●Do not attempt to install, remove, modify, disassemble or dispose of the
seat belts. Have any necessary repairs carried out by your Toyota dealer.
Inappropriate handling of the pretensioner may prevent it from operating
properly resulting in death or serious injury.
■Using a seat belt extender
●Do not wear the seat belt extender if you can fasten the seat belt without
the extender.
●Do not use the seat belt extender when installing a child restraint system
because the belt will not securely hold the child restraint system, increas-
ing the risk of death or serious injury in the event of an accident.
●The personalized extender may not be safe on another vehicle, when
used by another person, or at a different seating position other than the
one originally intended.

1-3. Adjustable components (seats, mirrors, steering wheel)
Before driving
Anti-glare inside rear view mirror
Glare from the headlights of vehicles behind can be reduced by
using the following functions.
Manual anti-glare inside rear view mirror
Normal position
Anti-glare position
Auto anti-glare inside rear view mirror
In automatic mode, sensors are used to detect the headlights of
vehicles behind and the reflected light is automatically reduced.
Turns automatic mode on/off
The indicator comes on when
automatic mode is turned on.
The mirror will revert to the
automatic mode each time the
engine switch is turned to the
“ON” position.

54 1-3. Adjustable components (seats, mirrors, steering wheel)
Adjusting the height of the rear view mirror
Adjust the height of the rear view
mirror by moving it up and down.
■To prevent sensor error
CAUTION
■Caution while driving
Do not adjust the position of the mirror while driving.
Doing so may lead to mishandling of the vehicle and an accident, resulting in
death or serious injury.
To ensure that the sensors operate prop-
erly, do not touch or cover them.

72 1-7. Safety information
Airbag system components
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on US motor vehicle safety standards (FMVSS208). The airbag sys-
tem controls airbag deployment power for the driver and front pas-
senger. The driver airbag system consists of the driver seat's position
sensor etc. The front passenger's airbag system consists of the front
passenger occupant classification sensor etc.Front airbag sensors

Before driving
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. The
airbag sensor assembly consists of a safing sensor and an airbag
sensor.
In certain types of severe frontal or side impacts, the SRS airbag sys-
tem triggers the airbag inflators. A chemical reaction in the inflators
quickly fills the airbags with non-toxic gas to help restrain the motion
of the occupants.

314 3-7. Other interior features
CAUTION
■While driving the vehicle
Do not adjust the display. Be sure to adjust the display only when the vehicle
is stopped.
■When doing the circling calibration
Be sure to secure a wide space, and watch out for people and vehicles in the
neighborhood. Do not violate any local traffic rules while performing circling
calibration.
NOTICE
■To avoid compass malfunctions
Do not place magnets or any metal objects near the anti-glare inside rear
view mirror.
Doing this may cause a malfunction of the compass sensor.
■To ensure normal operation of the compass
●Do not perform circling calibration of the compass in a place where the
earth's magnetic field is subject to interference by artificial magnetic fields.
●During calibration, do not operate electric systems (moon roof, power win-
dows, etc.) as they may interfere with the calibration.

5-1. Essential information
Event data recorder
In a crash or a near car crash event
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 follow-
ing 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 shift lever
●Whether the driver and front passenger wore seat belts or not
●Driver's seat position
●SRS airbag deployment data
●SRS airbag system diagnostic data
●Front passenger's occupant classification
The information above is intended to be used for the purpose of
improving vehicle safety performance. Unlike general data recorders,
the EDR does not record sound data such as conversation between
passengers.
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 an event
data recorder (EDR) that records data in a crash or a near car
crash event.

406 5-2. Steps to take in an emergency
buzzer sounds intermittently for 10 seconds after the vehicle has reached a
speed of 12 mph (20 km/h). Then, if the seat belt is still unfastened, the
buzzer will sound at a different tone for 20 more seconds.

3: Maintenance required reminder light:
Refer to the seperate “Scheduled Maintenace Guide” or “Owner’s Manual
Supplement” for the maintenance interval applicable to your vehicle.
■SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag
sensors, side and curtain shield airbag sensors, curtain shield airbag sen-
sors, driver's seat position sensor, driver's seat belt buckle switch, front pas-
senger occupant classification system, “AIR BAG ON” indicator light, “AIR
BAG OFF” indicator light, front passenger's seat belt buckle switch, seat belt
pretensioner assemblies, inflators, interconnecting wiring and power
sources. (P. 7 1 )
■Front passenger detection sensor and passenger seat belt reminder
●If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash, even if a passen-
ger is not sitting in the seat.
●If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
■
When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level.
Pushing the tire pressure warning reset switch does not turn off the tire
pressure warning light.
■The tire pressure warning light may turn on due to natural causes
The tire pressure warning light may turn on due to natural causes such
as natural air leaks or tire inflation pressure changes caused by temper-
ature. In this case, adjusting the tire inflation pressure will turn off the
warning light (after a few minutes).
