2012 TOYOTA TUNDRA airbag off

124 1-7. Safety information
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 right front
passenger. The driver airbag system consists of the driver seat’s
position sensor etc. The front pass enger’s airbag system consists of
the front passenger occupant classification sensor etc.
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.
Front bench type seat: The SRS airbags are designed to protect the
driver and right front passenger, and they are not designed to protect
an occupant in the front center seating position.
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. Side airbags

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 , RSCA OFF indicator light, inflators,
interconnecting wiring and power sources. ( P. 610)
■ 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 front windshield may crack.
■ Operating conditions (front airbags)
●The SRS front airbag will deploy in the event of an impact that exceeds
the set threshold level (the level of force corresponding to an approxi-
mately 12-18 mph [20-30 km/h] frontal collision with a fixed wall that does
not move or deform).
However, this threshold velocity will be considerably higher if the vehicle
strikes an object, such as a parked vehicle or sign pole, which can move or
deform on impact, or if the vehicle is involved in an underride collision (e.g.
a collision in which the front of the vehicle “underrides”, or goes under, the
bed of a truck, etc.).
● It is possible that in some collisions where the forward deceleration of the
vehicle is very close to the designed threshold level, the SRS front air-
bags and the seat belt pretensioners may not activate together.
● The SRS front passenger airbag will not activate if there is no passenger
sitting in the right front passenger seat. However, the front passenger air-
bag may deploy if luggage is put in the seat, or the seat belt is fastened,
even if the seat is unoccupied. ( P. 135)

CAUTION
■
SRS airbag precautions
●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 per form 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
pillars or roof side rails.
● Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment.
● Installation of snow plows, winches, etc. to the front grille (bull bars, kan-
garoo bar etc.).
● Modifications to the vehicle’s suspension system.
● Do not use tires or wheels other than the manufacturer’s recommended
size. ( P. 678)
● Installation of electronic devices such as mobile two-way radios or CD
players.
● Modifications to your vehicle for a person with a physical disability.

is in the ON position.)
The roll sensing function for the
curtain shield airbags and seat
belt pretensioners will turn back
on automatically each time the
engine switch is turned to the ON
position.
■The switch only should be used
In a situation where inflation is not desired (such as during extreme off-road
driving).
■ Operating conditions when th e RSCA OFF indicator is on
● The curtain shield airbag and seat belt pretensioner will not activate in a
vehicle rollover.
● The curtain shield airbag will activate in a severe side impact.
CAUTION

CAUTION
■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 right 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
illuminated, the front passenger airbag, front passenger knee airbag and
side airbag on the right front passenger side airbag may not activate cor-
rectly, 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 apply pressure to the right front passenger seat by resting hands or
legs on the seatback.
● Double Cab and CrewMax models: Do not put weight on the front passen-
ger seat by putting your hands or feet on the front passenger seat seat-
back from the rear passenger seat.

CAUTION
■
Front passenger occupant cl assification system precautions
● Double Cab and CrewMax models: 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.
● Do not recline the front passenger seatback so far that it touches a rear
seat or a back wall. 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 or
back wall, return the seatback to a position where it does not touch the
rear seat or back wall. 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.
● If an adult sits in the right front passenger seat, the AIR BAG ON indicator
light is illuminated. If the AIR BAG OFF indicator is illuminated, ask the
passenger to sit up straight, well back in the seat, feet on the floor, and
with the seat belt worn correctly. If the AIR BAG OFF indicator still remains
illuminated, either ask the passenger to move to the rear seat, or if that is
not possible, move the right front passenger seat fully rearward.
● When it is unavoidable to install the forward-facing child restraint system
on the front passenger seat, install the child restraint system on the front
passenger seat in the proper order. ( P. 144)
● Do not modify or remove the front seats.
● Do not kick the front passenger seat or subject it to severe impact. Other-
wise, the SRS warning light may come on to indicate a malfunction of the
detection system. In this case, contact your Toyota dealer immediately.
● Double Cab and CrewMax models: Child restraint systems installed on the
rear seat should not contact the front seatbacks.
● Do not use a seat accessory, such as a cushion or seat cover, that covers
the seat cushion surface.
● Do not attach a commercial seatback table or other heavy item to the back
of the front passenger seat.
● Do not modify or replace the upholstery of the front seat.
