2. Raise the bottom cushion while
pushing the lock release lever.
CAUTION
When returning the bottom cushion to
its original position, observe the fol-
lowing precautions in order to pre-
vent personal injury in a collision or
sudden stop:
Make sure the bottom cushion is
securely locked by trying to pull up
the edge of the bottom cushion.
Failure to do so will prevent the
seat belt from operating properly.
Make sure the seat belts are not
twisted or caught under the bottom
cushion and are arranged in their
proper position and are ready to
use.Front

For your safety and comfort, adjust the
head restraint before driving.
To raise: Pull it up.
To lower: Push it down while pressing the
lock release button.
The head restraint is most effective when
it is close to your head. Therefore, using
a cushion on the seatback is not recom-
mended.
CAUTION
Adjust the center of the head re-
straint so that it is closest to the
top of your ears.
After adjusting the head restraint,
make sure it is locked in position.
Do not drive with the head re-
straints removed.
Toyota strongly urges that the driver and
passengers in the vehicle be properly re-
strained at all times with the seat belts
provided. Failure to do so could increase
the chance of injury and/or the severity of
injury in accidents.
The seat belts provided for your vehicle
are designed for people of adult size,
large enough to properly wear them.
Child. Use a child restraint system ap-
propriate for the child until the child be-
comes large enough to properly wear the
vehicle’s seat belts. See “Child restraint”
for details.
STANDARD CAB MODELS—
If a child is too large for a child restraint
system, the child s hould sit in the seat
and must be restrained using the vehicle’s
seat belt.
ACCESS CAB MODELS—
If a child is too large for a child restraint
system, the child should sit in the rear
seat and must be restrained using the
vehicle’s seat belt. According to accident
statistics, the child is safer when properly
restrained in the rear seat than in the
front seat. If a child must sit in the front seat, the
seat belts should be worn properly. If an
accident occurs and the seat belts are not
worn properly, the force of the rapid infla-
tion of the airbag may cause death or
serious injury to the child.
Do not allow the child to stand up or
kneel on either rear or front seats. An
unrestrained child could suffer serious in-
jury or death during emergency braking or
a collision. Also, do not let the child sit
on your lap. It does not provide sufficient
restraint.
Smallframed person or youth in a
3point type seat belt.
On models with
a non −split bench seat, have a small −
framed person or youth sit slightly closer
to the center of the vehicle (so the shoul-
der belt does not cross over the neck).
On models with separate seats and a split
bench seat, move the seat fully backward.
Pregnant woman. Toyota recommends the
use of a seat belt. Ask your doctor for
specific recommendations. The lap belt
should be worn securely and as low as
possible over the hips and not on the
waist.

If the seat belt cannot be pulled out of the
retractor, firmly pull the belt and release
it. You will then be able to smoothly pull
the belt out of the retractor.
When a passenger ’s shoulder belt is com-
pletely extended and is then retracted
even slightly, the belt is locked in that
position and cannot be extended. This fea-
ture is used to hold the child restraint
system securely. (For details, see “Child
restraint” in this section.) To free the belt
again, fully retract the belt and then pull
the belt out once more.
CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the belt is not twisted.
Do not insert coins, clips, etc. in
the buckle as this may prevent you
from properly latching the tab and
buckle.
If the seat belt does not function
normally, immediately contact your
Toyota dealer. Do not use the seat
until the seat belt is fixed. It cannot
protect an adult occupant or your
child from injury.
Standard cab models

and slide the anchor down.
Access cab models—
To raise: Slide the anchor up.
To lower: Pull the lock release knob and
slide the anchor down.
After adjustment, make sure the anchor is
locked in position.
CAUTION
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
severe injuries in a co llision.

CAUTION
The SRS airbag system is designed
only as a supplement to the prima-
ry protection of the driver side and
right front passenger side seat belt
systems. The front seat occupants
can be killed or seriously injured by
the inflating airbags if they do not
wear the available seat belts prop-
erly. During sudden braking just be-
fore a collision, an unrestrained
driver or front passenger can move
forward into direct contact with or
close proximity to the airbag which
may then deploy during the colli-
sion. To ensure maximum protection
in an accident, the driver and all
passengers in the vehicle must
wear their seat belts properly. Wear-
ing a seat belt properly during an
accident reduces the chances of
death or serious injury or being
thrown out of the vehicle. For
instructions and precautions con-
cerning the seat belt system, see
“Seat belts” in this section.
Improperly seated and/or restrained
infants and children can be killed
or seriously injured by the deploy-
ing airbags. An infant or child who
is too small to use a seat belt
should be properly secured using a
child restraint system. As to access
cab models, Toyota recommends
that all infants and children be
placed in the rear seat of the ve-
hicle and properly restrained. The
rear seat is the safest for infants
and children. For instructions con-
cerning the installation of a child
restraint system, see “Child re-
straint” in this section.CAUTION
A member of a passenger risk group
should never sit or be occupied in
the right front passenger seat with
airbag manual onoff switch in the
“ON” position. (For details, see “SRS
driver airbag and front passenger air-
bag” in this section.)

proper child restraint system which
conforms to the size of the child,
installed on the rear seat. Accord-
ing to accident statistics, the child
is safer when properly restrained in
the rear seat than in the front seat.
Never put infant or child age 1 to
12 in a passenger risk group on the
right front seat with the passenger
airbag manual onoff switch in the
“ON” position. In the event of an
accident, the force of the rapid
inflation of the 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 front seat, make sure
the passenger airbag manual onoff
switch is in the “OFF” position and
that the indicator light is on. (For
details, see “SRS driver airbag and
front passenger airbag” in this sec-
tion.)

with all installation instructions pro-
vided by the child restraint
manufacturer and that the system is
properly secured.A child restraint system for a small
child or baby must itself be properly
restrained on the seat with either the
lap belt or the lap portion of the lap/
shoulder belt. You must carefully con-
sult the manufacturer ’s instructions
which accompany the child restraint
system.
To provide proper restraint, use a child
restraint system following the manufactur-
er ’s instructions about the appropriate age
and size of the child for the child restraint
system.
Install the child restraint system correctly
following the instructions provided by its
manufacturer. General directions are also
provided under the following illustrations.
The child restraint system should be
installed on the rear seat if your vehicle
is equipped with rear seats. According to
accident statistics, the child is safer when
properly restrained in the rear seat than
in the front seat.

After installing the child restraint
system, make sure it is secured in
place according to the manufactur-
er’s instructions. If it is not re-
strained securely, it may cause
death or serious injury to the child
in the event of a sudden stop or
accident.
When not using the child restraint system,
keep it secured with the seat belt or place
it somewhere other than the passenger
compartment. This will prevent it from in-
juring passengers in the event of a sud-
den stop or accident. Child restraint systems are classified into
the following 3 types depending on the
child’s age and size.
(A) Infant seat
(B) Convertible seat
(C) Booster seat
Install the child restraint system following
the instructions provided by its manufac-
turer.
Your vehicle has anchor brackets for se-
curing the top strap of a child restraint
system.
For instructions on how to use the anchor
bracket, see “—Using a top strap” in this
section.
The child restraint lower anchorages ap-
proved for your vehicle may also be used.
