vehicle is subjected to a collision from
the side at certain angles, or a collision
to the side of the vehicle body other
than the passenger compartment as
shown in the illustration.
The SRS side airbags and curtain shield
airbags are designed to inflate when the
passenger compartment area suffers a se-
vere impact from the side.

driver’s seat belt buckle switch, front pas-
senger occupant classification system,

assemblies, inflators, interconnecting wir-
ing and power sources. (For details, see
“Service reminder indicators and warning
buzzers” on page 191 in Section 1−6.)
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 “ON” position, the light does not
come on, remains on for more than 6
seconds or flashes.

system and/or front passenger occupant
classification system and “AIR BAG ON”
and “AIR BAG OFF” indicator lights have
a problem. If the light flashes, the SRS
side airbag system and/or curtain shield
airbag system have a problem.

dealer as soon as possible:
Any of the SRS side airbags and cur-
tain shield airbags have been inflated.
The portion of the doors (shaded in the
illustration) was involved in an accident
that was not severe enough to cause

The surface of the seats with the side
airbag (shaded in the illustration) is
scratched, cracked, or otherwise dam-
aged.
The portion of the front pillars, side
pillars or roof side rail garnishes (pad-

NOTICE
Do not disconnect the battery cables
before contacting your Toyota dealer.
Your vehicle is equipped with a front
passenger occupant classification sys-
tem. This system detects the conditions
1—4 in the table on page 137 and based
on these conditions activates or deacti-
vates the following systems;
Front passenger airbag
Side airbag on the front passenger
seat
Front passenger ’s seat belt pretension-
er
The system monitors the weight and
load on the front passenger seat, and
the seat belt buckle switch to determine
conditions 1—4.
In order for the system to detect the
conditions correctly, do not do any of
the following:
Apply a heavy load to the front pas-
senger seat or equipment (e.g. seat-
back table, grocery bag hooks, armrest
or auxiliary box).
Attach a commercial seatback table,
etc. to the front passenger seat seat-
back.
Put weight on the front passenger seat
by putting your hands or feet on the
seatback from the rear passenger seat.
The “AIR BAG ON” and “AIR BAG OFF”
indicator lights indicate the actuation of
the front passenger airbag, side airbag
on the front passenger seat and front
passenger ’s seat belt pretensioner.
The “AIR BAG OFF” indicator light will be
illuminated when the engine switch is in
the “ON” position with the condition 2 in
the table shown below.

If the front passenger occupant classifica-
tion system determines that a person of
adult size sits in the front passenger seat
but the “AIR BAG OFF” indicator light is
illuminated, one of the following is likely
to have occurred:
A rear passenger lifts the front passen-
ger seat cushion with their legs.
Objects are placed under the front pas-
senger seat.
The front passenger seatback is in
contact with the second seat.
To ensure the system correctly detects an
adult sitting in the front passenger seat,
make sure the above do not occur.
Make sure that the “AIR BAG ON” indica-
tor light is illuminated when an adult is
seated in the front passenger seat. If the
“AIR BAG OFF” indicator light is illumina-
ted, ask the passenger to sit up straight,
well back in the seat, and with the seat
belt worn correctly. If the “AIR BAG OFF”
indicator light still remains illuminated, ei-
ther ask the passenger to move to the
rear seat, or if that is not possible, move
the front passenger seat fully rearward. The “AIR BAG ON” and “AIR BAG OFF”
indicator lights will be illuminated ini-
tially when the engine switch is turned
to the “ON” position. After about 4 sec-
onds, they will go off. After that, the
front passenger occupant classification
system operates and judges which indi-
cator light be illuminated.
The SRS warning light and “AIR BAG
OFF” indicator light will come on if
there is a malfunction in the front pas-
senger occupant classification system.

∗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
recognize him/her as a child depending on his/her physique and posture.
∗2: When a larger child who has outgrown a child restraint system sits in the front passenger seat, the system may recognize him/h er
as an adult depending on his/her physique or posture.
∗ 3: Never install a rear −facing child restraint system on the front passenger seat. A forward −facing child restraint system should only be
installed on the front passenger seat when it is unavoidable. (See “Child restraint” on page 139 in this Section as for install ing the
child restraint system.)
