2005 TOYOTA TUNDRA warning

’05 TUNDRA_U (L/O 0408)

2005 TUNDRA from Aug. ’04 Prod. (OM34427U)
Without tachometer
With tachometer
The SRS warning light and the front
passenger occupant classification indi-
cator light or passenger airbag manual
on−off indicator light will indicate
“OFF” if there is a malfunction in the
passenger airbag manual on −off switch.
CAUTION
Do not turn off the passenger air-
bag manual on− off switch except
when a member of a passenger risk
group identified in TABLE 1 is oc-
cupying the right front passenger
seating position.
When the passenger airbag manual
on− off switch is turned off, the pas-
senger airbag will not inflate in a
collision and turning off the pas-
senger airbag can reduce the occu-
pant protection which your vehicle
safety systems can provide to you
in certain accidents and increase
the likelihood of serious personal
injuries.
For details, see “SRS driver airbag
and front passenger airbag” in this
Section.
The SRS (Supplemental Restraint Sys-
tem) side airbags and curtain shield air-
bags are designed to provide further
protection for the driver, front passen-
ger and rear outside passengers in
addition to the primary safety protec-
tion provided by the seat belts.

The SRS side and curtain shield airbags
may deploy if a serious impact occurs
to the underside of your vehicle. Some
examples are shown in the illustration.The SRS side airbag and curtain shield
airbag system consists mainly of the fol-
lowing components, and their locations are
shown in the illustration. 1. SRS warning light
2. Separate seat only—Front passenger occupant classification indicator light
3. Curtain shield airbag modules (airbag and inflator)
4. Separate seat only—Front passenger occupant classification system (ECU
and sensors)
5. Side airbag modules (airbag and inflator)
6. Curtain shield airbag sensors 7. Side and curtain shield airbag sensors
8. Front passenger ’s seat belt buckle
switch
9. Airbag sensor assembly
The SRS side airbag and curtain shield
airbag system is controlled by the airbag
sensor assembly. The airbag sensor as-
sembly consists of a safing sensor and
airbag sensor.
In a severe side impact, the side and
curtain shield airbag sensor and/or the
curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain
shield airbag inflators. At this time a
chemical reaction in the inflators quickly
fills the airbags with non −toxic gas to help
restrain the lateral motion of the occu-
pants.
In a vehicle rollover, the airbag sensor
assembly triggers the curtain shield airbag
inflator. At this time, a chemical reaction
in the inflators quickly fills the airbags
with non −toxic gas to help restrain the
lateral motion of the occupants.

This indicator comes on when the igni-
tion key is turned to the “ON” position.
It goes off after about 6 seconds. This
means the SRS side airbags and curtain
shield airbags 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 and indicator light,
front passenger ’s seat belt buckle switch,
seat belt pretensioner assemblies, inflat-
ors, warning light, “RSCA OFF” indicator
light, interconnecting wiring and power
sources. (For details, see “Service remind-
er indicators and warning buzzers” in Sec-
tion 1
−6.)
If either 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 key is turned to the “ON” posi-
tion or remains on for more than 6
seconds.
The light comes on while driving.
Vehicles with separate seat only—The
SRS warning light will come on and front
passenger occupant classification indicator
light will indicate “OFF” if there is a mal-
function in the front passenger occupant
classification system.

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 rear 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 “ON” indicator is illu-
minated when an adult is seated in the
front passenger seat. If the “OFF” indica-
tor is illuminated, ask the passenger to sit
up straight, well back in the seat, and
with the seat belt worn correctly. If the
“OFF” indicator still remains illuminated,
either ask the passenger to move to the
rear seat, or if that is not possible, move
the front passenger seat fully rearward.
The front passenger occupant classifi-
cation indicator light will indicate “ON”
and “OFF” when the ignition key is
turned to the “ON” position. After
about four seconds, it will go off. After
that, the front passenger occupant clas-
sification system operates and judges
whether to indicate “ON” or “OFF”.

The SRS warning light will come on

installed on the front passenger seat when it is unavoidable. (See “Child restraint” in this Section as for installing the chil d restraint
system.)

When it is unavoidable to install the
forward −facing child restraint sys-
tem on the front passenger seat,
install the child restraint system on
the front passenger seat in the
proper order. (As for the installation
order, see “—Installation with seat
belt” in this Section.)
Do not remove the front seats.
Do not kick the front passenger
seat or subject it to severe impact.
Otherwise, the SRS warning light
may come on to indicate a malfunc-
tion of the detection system. In this
case, contact your Toyota dealer im-
mediately.
The front passenger occupant classifica-
tion indicator light may indicate “ON” (the
front passenger airbag and side airbag on
the front passenger seat may deploy)
even if observing the above cautions,
when a child sits in, or a forward −facing
child restraint system is installed on the
front passenger seat. Refer to all the cau-
tions in “SRS driver airbag and front pas-
senger airbag”, “SRS side airbags and
curtain shield airbags” and “Child restraint”
in this Section.
The roll sensing of curtain shield air-
bags off switch (“RSCA OFF” switch)
can turn off the curtain shield airbags
and seat belt pretensioners in a vehicle
rollover. This switch should only be
used if inflation is not desired (such as
extreme off −road driving).
When you push the “RSCA OFF” switch
for a few seconds with the ignition switch
on, the “RSCA OFF” indicator light comes
on and the roll sensing function is turned
off. When you push the switch again, the
indicator light goes off and the roll sens-
ing function is turned on. (For details
about the roll sensing function, see “SRS
side airbags and curtain shield airbags” in
this Section.) In a severe side impact, the curtain shield
airbags on impacted side will inflate even
if the roll sensing function is turned off.
(For details about the curtain shield air-
bags, see “SRS side airbags and curtain
shield airbags” in this Section.)
In a severe frontal impact, the seat belt
pretensioners will work even if the roll
sensing function is turned off. (For details
about the seat belt pretensioners, see
“—Seat belt pretensioners” in this Sec-
tion.)
If the ignition switch is turned to “ACC” or
“LOCK” with the roll sensing function off
and then the ignition switch is turned back
to “ON”, the roll sensing function will turn
back on automatically.
