361-1. For safe use
CAUTION
■When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, it may lead to choking or other serious injuries
that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
■ Seat belt pretensioners
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the seat belt
pretensioner for the front passenger’s seat may not activate in the event of
a collision.
● If the pretensioner has activated, the SRS warning light will come on. In
that case, the seat belt cannot be used again and must be replaced at
your Toyota dealer.
■ Adjustable shoulder anchor (D ouble Cab and CrewMax models)
Always make sure the shoulder belt is positioned across the center of your
shoulder. The belt should be kept away from your neck, but not falling off
your shoulder. Failure to do so could reduce the amount of protection in an
accident and cause death or serious injuries in the event of a sudden stop,
sudden swerve or an accident. (→ P. 33)
■ Seat belt damage and wear
● Do not damage the seat belts by allowing the belt, plate, or buckle to be
jammed in the door.
● Inspect the seat belt system periodically. Check for cuts, fraying, and loose
parts. Do not use a damaged seat belt until it is replaced. Damaged seat
belts cannot protect an occupant from death or serious injury.
● Ensure that the belt and plate are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact your Toyota
dealer.
● Replace the seat assembly, including the belts, if your vehicle has been
involved in a serious accident, even if there is no obvious damage.
● Do not attempt to install, remove, modify, disassemble or dispose of the
seat belts. Have any necessary repairs carried out by your Toyota dealer.
Inappropriate handling of the pretensioner may prevent it from operating
properly, resulting in death or serious injury.

For safety and security
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag
sensor assembly (ECU ) controls airbag deployment based on infor-
mation obtained from the sensors et c. shown in the system compo-
nents diagram above. This informat ion includes crash severity and
occupant information. As the airbags deploy, a chemical reaction in
the inflators quickly fills the airbag s with non-toxic gas to help restrain
the motion of the occupants.
Front bench type seat: The SRS airbags are designed to protect the
driver and right front passenger, an d they are not designed to protect
an occupant in the front center seating position.

CAUTION
■Front passenger occupant classi fication system precautions
● 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 SRS airbags for the front passen-
ger will not activate 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 seat-
back as upright as possible when the vehicle is moving. Reclining the
seatback excessively may lessen the effectiveness of the seat belt sys-
tem.
● If an adult sits in the 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 front passenger seat fully rearward.
● When it is unavoidable to install a forward-facing child restraint system on
the front passenger seat, install the child restraint system on the front pas-
senger seat in the proper order. ( →P. 60)
● 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
front passenger occupant classification 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 and seat cover, that cov-
ers 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.
