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 rest rain the motion
of the occupants.
■ SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag
sensors, side and curtain shield airbag sensor assemblies, curtain shield air-
bag sensor assemblies, driver's seat position sensor, driver's seat belt
buckle switch, front passenger occupant classification system, “AIR BAG
ON” and “AIR BAG OFF” indicator lights, front passenger’s seat belt buckle
switch, front seat belt pretensioner assemblies, inflators, interconnecting wir-
ing and power sources. ( P. 505)
■ If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the front seats, and parts of the front and rear pillars and roof
side rail, may be hot for several minutes. The airbag itself may also be
hot.
● The windshield may crack.

128 1-7. Safety information
CAUTION
■SRS airbag precautions
●Do not touch any of the component parts immediately after the SRS air-
bags have deployed (inflated) as they may be hot.
● If breathing becomes difficult after the SRS airbag has deployed, open a
door or window to allow fresh air in, or leave the vehicle if it is safe to do
so. Wash off any residue as soon as possible to prevent skin irritation.
● If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garnishes, are damaged or cracked, have
them replaced by your Toyota dealer.
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications
without consulting your Toyota dealer.
The SRS airbags may malfunction or deploy (inflate) accidentally, causing
death or serious injury.
● Installation, removal, disassembly and repair of the SRS airbags.
● Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, side and rear

*1: The system judges a person of adult size as an adult. When a smaller adult sits in the front passenger seat, the system may rec-
ognize him/her as a child depending on his/her physique and pos-
ture.
*2: In the event the front passenger does not wear a seat belt.
*3: When a larger child who has outgrown a child restraint system sits in the front passenger seat, the system may recognize him/
her as an adult depending on his/her physique or posture.

Front passenger occupant cl assification system precautions
Observe the following precautions regarding front passenger occupant clas-
sification system.
Failure to do so may cause death or serious injury.
● Wear the seat belt properly.
● Make sure the front passenger's seat belt tab has not been left inserted
into the buckle before someone sits in the front passenger seat.
● Make sure the “AIR BAG OFF” indicator light is not illuminated when using
the seat belt extender for the front passenger seat. If the “AIR BAG OFF”
indicator light is illuminated, disconnect the extender tongue from the seat
belt buckle, then reconnect the seat belt. Reconnect the seat belt extender
after making sure the “AIR BAG ON” indicator light is illuminated. If you
use the seat belt extender while the “AIR BAG OFF” indicator light is illumi-
nated, the front passenger airbag, side airbag on the front passenger side
may not activate correctly, which could cause death or serious injury in the
event of collision.
● Do not apply a heavy load to the front passenger seat or equipment (e.g.
seatback pocket).
● Do not put weight on the front passenger seat by putting your hands or
feet on the front passenger seat seatback from the rear passenger seat.
● Do not let a rear passenger lift the front passenger seat with their feet or
press on the seatback with their legs.
● Do not put objects under the front passenger seat except for putting them
in the tray.
● Do not recline the front passenger seatback so far that it touches a rear
seat. This may cause the “AIR BAG OFF” indicator light to be illuminated,
which indicates that the passenger's airbags will not deploy in the event of
a severe accident. If the seatback touches the rear seat, return the seat-
back to a position where it does not touch the rear seat. Keep the front\
passenger seatback as upright as possible when the vehicle is moving.
Reclining the seatback excessively may lessen the effectiveness of the
seat belt system.

Selecting an appropriat e child restraint system
● Use a child restraint system appropriate for the child until the child
becomes large enough to properly wear the vehicle’s seat belt.
● If a child is too large for a child restraint system, sit the child on a rear
seat and use the vehicle's seat belt. ( P. 84)
CAUTION
■Child restraint precautions
●For effective protection in automobile accidents and sudden stops, a child
must be properly restrained, using a seat belt or child restraint system
depending on the age and size of the child. Holding a child in your arms is
not a substitute for a child restraint system. In an accident, the child can be
crushed against the windshield, or between you and the vehicle's interior.
● Toyota strongly urges the use of a proper child restraint system that con-
forms to the size of the child, installed on the rear seat. According to acci-
dent statistics, the child is safer when properly restrained in the rear seat
than in the front seat.
● Never install a rear-facing child restraint system on the front passenger
seat even if the “AIR BAG OFF” indicator light is illuminated. In the event
of an accident, the force of the rapid inflation of the front passenger airbag
can cause death or serious injury to the child if the rear-facing child
restraint system is installed on the front passenger seat.
● A forward-facing child restraint system may be installed on the front pas-
senger seat only when it is unavoidable. A child restraint system that
requires a top tether strap should not be used in the front passenger seat
since there is no top tether strap anchor for the front passenger seat.
Adjust the seatback as uprights as possible and always move the seat as
far back as possible even if the “AIR BAG OFF” indicator light is illumi-
nated, because the front passenger airbag could inflate with considerable
speed and force. Otherwise, the child may be killed or seriously injured.

CAUTION
■
When installing a booster seat
Do not fully extend the shoulder belt to prevent the belt from going to ALR
lock mode: ( P. 87)
ALR mode causes the belt to tighten only which could cause injury or dis-
comfort to the child.
■ When installing a child restraint system
Follow the directions given in the child restraint system installation manual
and fix the child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child or other
passengers may be seriously injured or even killed in the event of sudden
braking or an accident.
●If the driver's seat interferes with the
child restraint system and prevents it
from being attached correctly, attach
the child restraint system to the right-
hand rear seat.
● Adjust the front passenger seat or sec-
ond seats so that it does not interfere
with the child restraint system.
● Only put a forward-facing or booster
child seat on the front seat when
unavoidable. When installing a forward-
facing or booster child seat on the front
passenger seat, move the seat as far
back as possible even if “AIR BAG
OFF” indicator light is illuminated. Fail-
ing to do so may result in death or seri-
ous injury if the airbags deploy (inflate).

CAUTION
■If a safety system warning light does not come on
Should a safety system light such as the ABS or SRS airbag warning light
not come on when you start the engine, this could mean that these systems
are not available to help protect you in an accident, which could result in
death or serious injury. Have the vehicle inspected by your Toyota dealer
immediately if this occurs.
■ Warning lights
Warning lights inform the driver of malfunctions in any of the
vehicle’s systems. ( P. 504)
*1: These lights turn on when the engine switch is turned to the “ON”
position to indicate that a system check is being performed. They
will turn off after the engine is started, or after a few seconds. There
may be a malfunction in a system if a light does not come on, or if
the lights do not turn off. Have the vehicle inspected by your Toyota
dealer for details.
