Essential Safety Equipment
X: The SRS air bag equipment is designed to deploy in a collision.
*1:The front passenger front and side air bags and the seat belt pretensioner
are designed to deploy when the front passenger occupant classification
sensor detects a passenger sitting on the front passenger’s seat.
*2:In a side collision, the seat belt pretensioners and the side/curtain air bags
deploy (only on the side in which the collision occurs).
*3:In a roll-over accident, the seat belt pretensioners and the curtain air bags
deploy.
In a frontal offset collision, the equipped air bags and pretensioners may all
deploy depending on the direction, angle, and rate of impact.

The following illustrations are examples of side collisions that may not
be detected as severe enough to deploy the SRS air bag equipment.
Side impacts involving trees or
poles
Side impacts with two-wheeled
vehicles
The following illustration is an exam ple of an accident that may not be
detected as a roll-over accident. Ther efore, the front seat belt preten-
sioners and curtain air bags may not deploy.

Front Passenger Occupant Classification
System
Your vehicle is equipped with a front passenger occupant classifica-
tion sensor as a part of the supple mental restraint system. This sen-
sor is equipped in the front passen ger’s seat cushion. This sensor
measures the electrostatic capacity of the front passenger’s seat. The
SAS unit is designed to prevent th e front passenger front and side air
bags and seat belt pretensioner syst em from deploying if the front
passenger air bag deactivation indicator light turns on.
To reduce the chance of injuries caused by deployment of the front
passenger air bag, the system deactivates the front passenger front
and side air bags and also the seat belt pretensioner system when the
front passenger air bag deactivation indicator light turns on. Refer to
the following table for the front pas senger air bag deactivation indica-
tor light illumination conditions.
This system shuts off the front pa ssenger front and side air bags and
seat belt pretensioner system, so make sure the front passenger air
bag deactivation indicator light turns on according to the following
table.
The air bag/front seat belt pretensioner system warning light flashes
and the front passenger air bag deactivation indicator light illuminates
if the sensors have a possible malfun ction. If this happens, the front
passenger front and side air bags and seat belt pretensioner system
will not deploy.
First, please read “Supplementa l Restraint System (SRS) Pre-
cautions” ( →P. 62) carefully.

■Front passenger air bag deactivation indicator light
This indicator light turns on to
remind you that the front pas-
senger front and side air bags
and seat belt pretensioner will
not deploy during a collision.
If the front passenger occupant classification sensor is normal, the
indicator light turns on when the ignition is switched ON. The light
turns off after a few seconds. Then, the indicator light turns on or is
off under the following conditions:

*1: The occupant classification sensor may not detect a child seated on the seat, in a child-restraint system, or a junior seat depending on the child’s
physical size and seated posture.
*2: If a smaller adult sits on the front passenger seat, the sensors might detectthe person as being a child depending on the person’s physique.
The curtain air bag is ready for inflating regardless of what the front
passenger air bag deactivation indi cator light on/off condition chart
indicates.

If the front passenger air bag deactivation indicator light does not
turn on when the ignition is switched ON and does not turn on as
indicated in the front passenger air bag deactivation indicator light
on/off condition chart, do not allow an occupant to sit in the front
passenger seat and consult your To yota dealer as soon as possi-
ble. The system may not work properly in an accident.
●The system requires about 10 seconds to alternate between turning the
front passenger front and side air bags and seat belt pretensioner system on
or off.
● The front passenger air bag deactivation indicator light may turn on repeat-
edly if luggage or other items are put on the front passenger seat, or if the
temperature of the vehicle’s interior changes suddenly.
● The front passenger air bag deactivation indicator light may turn on for 10
seconds if the electrostatic capacity on the front passenger seat change\
s.
● The air bag/front seat belt pretensioner system warning light might turn on if
the front passenger seat receives a severe impact.
● If the front passenger air bag deactivation indicator light does not turn on
after installing a child-restraint system on the front passenger seat, first, re-
install your child-restraint system according to the procedure in this owner’s
manual. Then, if the front passenger air bag deactivation indicator light still
does not turn on, install the child-restraint system on the rear seat and con-
sult your Toyota dealer as soon as possible.
● If the front passenger air bag deactivation indicator light turns on when an
occupant is seated directly in the front passenger seat, have the passenger
re-adjust their posture by sitting with their feet on the floor, and then re-fas-
tening the seat belt. If the front passenger air bag deactivation indicator light
remains turned on, move the passenger to the rear seat. If sitting in the rear
seat is not possible, slide the front passenger seat as far back as possible.
Consult your Toyota dealer as soon as possible.

WARNING
■Do not allow an occupant in the front passenger’s seat to sit with a
posture which makes it difficult for the front passenger occupant clas-
sification sensor to detect the occupant correctly
● A seat cover is put on the front passenger’s seat.
● Luggage or other items are placed on the seat with the child in the child-
restraint system.
● A rear passenger or luggage push or pull down on the front passenger
seatback.
● Luggage or other items are placed on the seatback or hung on the head
restraint.
● The seat is washed.
● Liquids are spilled on the seat.
● The front passenger seat is moved backward, pushing into luggage or
other items placed behind it.
● The front passenger seatback contacts the rear seat.
● Luggage or other items are placed between the front passenger seat and
driver seat.
● An electric device is put on the front passenger’s seat.
● An additional electrical device, such as a seat warmer is installed to the
surface of the front passenger seat.
The front passenger front and side air bags and seat belt pretensioner sys-
tems will deactivate if the front passenger air bag deactivation indicator light
turns on.
NOTICE
●To assure proper deployment of the front air bag and to prevent damage to
the sensor in the front seat cushion:
• Do not place sharp objects on the front seat cushion or leave heavy lug-
gage on them.
• Do not spill any liquids on the front seats or under the front seats.
● To allow the sensors to function properly, always perform the following:
• Adjust the front seats as far back as possible and always sit upright
against the seatbacks with seat belts worn properly.
• If you place your child on the front passenger seat, secure the child-
restraint system properly and slide the front passenger seat as far back
as possible ( →P. 50).

diagnostic system: • Crash sensors, and diagnostic module (SAS unit)
• Front air bag sensors
• Air bag modules
• Side crash sensors
• Air bag/Front seat belt pretensioner system warning light
• Front seat belt pretensioners
• Related wiring
• Front passenger air bag d eactivation indicator light
• Front passenger occup ant classification sensor
• Front passenger occup ant classification module
The diagnostic module continuously monitors the system’s readiness.
