2009 TOYOTA TUNDRA light

118 1-7. Safety information
■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,
passenger airbag off switch (Regular C ab models), front seat belt preten-
sioner assemblies, RSCA OFF indicator light, inflators, interconnecting wir-
ing and power sources. ( P. 546)
■ 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 airbags will deploy if the severity of the frontal impact is
above the designed threshold level, comparable to an approximate 15
mph (25 km/h) collision when the vehicle impacts straight into a fixed bar-
rier 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. 131)

122 1-7. Safety information
CAUTION
■SRS airbag precautions
Observe the following precautions regarding the airbags.
Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts
properly.
The SRS airbags are supplemental devices to be used with the seat belts.
● The SRS driver airbag deploys with considerable force, and can cause
death or serious injury especially if the driver is very close to the airbag.
The National Highway Traffic Safety Administration (“NHTSA”) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm)
of inflation, placing yourself 10 in. (250 mm) from your driver airbag pro-
vides you with a clear margin of safety. This distance is measured from the
center of the steering wheel to your breastbone. If you now sit less than 10
in. (250 mm) away, you can change your driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals comfortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many drivers can achieve the 10 in.
(250 mm) distance, even with the driver seat all the way forward, sim-
ply by reclining the back of the seat somewhat. If reclining the back of
your seat makes it hard to see the road, raise yourself by using a firm,
non-slippery cushion, or raise the seat if your vehicle has that feature\
.
• If your steering wheel is adjustable, tilt it downward. This points the air- bag toward your chest instead of your head and neck.
● The surface of the seats with the side
airbag is scratched, cracked or other-
wise damaged.
● The portion of the front pillars, rear pil-
lars or roof side rail garnishes (padding)
containing the curtain shield airbags
inside is scratched, cracked or other-
wise damaged.

Before driving
Passenger airbag off switch (Regular Cab models)
The passenger airbag off switch is designed to disable the front pas-
senger airbag in order to allow us age, if necessary, of the right pas-
senger seat by a member of a passenger risk group identified in
TABLE 1 ( P. 128).
AUTO position
This position makes the front pas-
senger airbag system opera-
tional.
At this time, the indicator light
condition varies depending on the
size of the occupant in the right
passenger seat.
OFF position
The front passenger airbag is dis-
abled.
At this time, the AIR BAG OFF
indicator light will come on.
■Operation of the passenger airbag off switch
Turn the key clockwise to the
AUTO position.
Turn the key counterclock-
wise to the OFF position and
remove it.
If the key is removed at any other
position than OFF, the switch will
automatically return to the AUTO
position.

Before driving
*1: The right front passenger on the bench type seat.
*
2: 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.
*
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.
*
4: Never install a rear-facing child restraint system on the front pas-
senger seat. A forward-facing ch ild restraint system should only
be installed on the front passenger seat when it is unavoidable.
(  P. 138)
*
5: In the event the front passenger does not wear a seat belt.
*
6: In case the indicator is not illu minated, consult this manual for
installing the child restra int system properly. (P. 138)
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, side airbag on the right front pas-
senger side airbag may not activate correctly, which could cause death or
serious injury in the event of collision.

136 1-7. Safety information
CAUTION
■Front passenger occupant cl assification system precautions
● 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.
● 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.
