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.

140 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. 148)
● 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.

CAUTION
■
Front passenger occupant cl assification system precautions
● 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.

1-7. Safety information
Child restraint systems
Points to rememberStudies have shown that installing a child restraint on a rear seat is
much safer than installing one to the front passenger seat.
● Choose a child restraint system th at suits your vehicle and is
appropriate to the age and size of the child.
● For installation details, follow the instructions provided with the
child restraint system.
General installation instructions are provided in this manual.
( P. 148)
Types of child restraints
Child restraint systems are clas sified into the following 3 types
according to the age and size of the child.
Rear facing  Infant seat/convertible seat
A child restraint system for a small ch ild or baby must itself be prop-
erly restrained on the seat with the lap portion of the lap/shoulder
belt.
The laws of all 50 states of the U.S.A. and Canada now require the
use of child restraint systems.

 Convertible seat

■ Selecting an appropriat e child restraint system
● Use a child restraint system appropriate for the child until the child
becomes large enough to properly wear the vehicle’s seat belt.
● If a child is too large for a child restraint system, sit the child on a rear
seat and use the vehicle’s seat belt. ( P. 75)

144 1-7. Safety information
CAUTION
■Child restraint precautions
●For effective protection in automobile accidents and sudden stops, a child
must be properly restrained, using a seat belt or child restraint system
depending on the age and size of the child. Holding a child in your arms is
not a substitute for a child restraint system. In an accident, the child can be
crushed against the windshield, or between you and the vehicle’s interior.
● Regular Cab models: Toyota strongly urges use of a proper child restraint
system which conforms to the size of the child.
● Double Cab and CrewMax models: Toyota strongly urges the use of a
proper child restraint system that conforms to the size of the child, installed
on the rear seat. According to accident statistics, the child is safer when
properly restrained in the rear seat than in the front seat.
● Regular Cab models: Never put infant or child age 1 to 12 in a passenger
risk group on the right passenger seat with the passenger airbag off switch
in the AUTO position. In the event of an accident, the force of the rapid
inflation of the front passenger airbag can cause death or serious injury to
the child. If you must put infant or child age 1 to 12 in a passenger risk
group on the right passenger seat, make sure that the passenger airbag
off switch is in the OFF position with the key removed and that the indica-
tor light is on. ( P. 131)
● Double Cab and CrewMax models: Ne ver install a rear-facing child
restraint system on the front passenger seat even if the AIR BAG OFF
indicator light is illuminated. In the event of an accident, the force of the
rapid inflation of the front passenger airbag can cause death or serious
injury to the child if the rear-facing child restraint system is installed on the
front passenger seat.
