CAUTION
■When adjusting a rear seat (CrewMax models)
●Be careful that the seat does not hit passengers or luggage.
● Do not recline the seat more than necessary when the vehicle is in motion
to reduce the risk of sliding under the lap belt. If the seat is too reclined,
the lap belt may slide past the hips and apply restraint forces directly to the
abdomen or your neck may contact the shoulder belt, increasing the risk of
death or serious injury in the event of an accident.
● Be careful not to get your hands or feet caught in the seat.
■ Before folding down a rear seat
Do not fold down a rear seat when there are passengers sitting in the rear
seats or when there is luggage placed on/under the rear seats.
■ After adjusting a seat (CrewMax models)
Observe the following precautions. Failure to do so may result in death or
serious injury.
●Make sure that the seat and seatback are securely locked in position by
lightly rocking them back and forth.
● Check that the seat belts are not twisted or caught in the seat.
■ When the seatback is folded/the bo ttom cushion is raised (Double Cab
models)
Do not sit on or place anything on the seatback or storage box while driving.
■ When returning the seats to their original position
Observe the following precautions. Failure to do so may result in death or
serious injury.
●Be careful not to get your hands or feet pinched in the seat.
● Make sure the seatbacks and bottom cushions are securely locked. Fail-
ure to do so will prevent the seat belt from operating properly.
● Check that the seat belts are not twisted or caught in the seat.
● Arrange the seat belts in the proper positions for ready use.

■Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult
size.
●Use a child restraint system appropriate for the child, until the child
become large enough to properly wear the vehicle’s seat belt. ( P. 138)
● When the child becomes large enough to properly wear the vehicle’s
seat belt, follow the instructions on P. 75 regarding seat belt usage.
■ Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will activate
for the first collision, but will not activate for the second or subsequent colli-
sions.
■ Seat belt extender
CAUTION
Observe the following precautions to reduce the risk of injury in the event of
sudden braking or an accident.
Failing to do so may cause death or severe injury.
■Wearing a seat belt
●Ensure that all passengers wear a seat belt.
● Always wear a seat belt properly.
● Each seat belt should be used by one person only. Do not use a seat belt
for more than one person at once, including children.
● Toyota recommends that children be seated in the rear seat and always
use a seat belt and/or an appropriate child restraint system.
If your seat belts cannot be fastened
securely because they are not long
enough, a personalized seat belt
extender is available from your Toyota
dealer free of charge.

82 1-3. Adjustable components (seats, mirrors, steering wheel)
CAUTION
■Before using a front seat be lt (Regular Cab models)
Make sure the seat belt hanger is secured in the raised position before you
fasten the seat belt.
■ Using a seat belt extender
●Do not wear the seat belt extender if you can fasten the seat belt without
the extender.
● Do not use the seat belt extender when installing a child restraint system
because the belt will not securely hold the child restraint system, increas-
ing the risk of death or injury in the event of a collision.
● The personalized extender may not be safe on another vehicle, when
used by another person, or at a different seating position other than the
one originally intended.
NOTICE
■When using a seat belt extender
When releasing the seat belt, press on the buckle release button on the
extender, not on the seat belt.
This helps prevent damage to the vehicle interior and the extender itself.

1-7. Safety information

Before driving
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 rest rain the motion
of the occupants. Side airbags

Before driving
CAUTION
■
SRS airbag precautions
The seat should be adjusted as recommended by NHTSA above, while still
maintaining control of the foot pedals and steering wheel, and your view of
the instrument panel controls.
●The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
● Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too small
to use a seat belt should be properly secured using a child restraint sys-
tem. Toyota strongly recommends that all infants and children be placed in
the rear seats of the vehicle and properly restrained. The rear seats are
the safest for infants and children. ( P. 138)
●If the seat belt extender has been con-
nected to the driver’s seat belt buckle
but the seat belt extender has not also
been fastened to the latch plate of the
driver’s seat belt, the SRS driver’s air-
bag system will judge that the driver is
wearing the seat belt even though the
seat belt has not been connected. In
this case, the driver’s airbag may not
activate correctly in a collision, resulting
in death or serious injury in the event of
collision. Be sure to wear the seat belt
with the seat belt extender.
