CAUTION
To reduce the risk of sliding under
the lap belt during a collision, avoid
reclining the seatback any more than
needed. The seat belts provide maxi-
mum protection in a frontal or rear
collision when the driver and the pas-
senger are sitting up straight and
well back in the seats. If you are
reclined, the lap belt may slide past
your hips and apply restraint forces
directly to the abdomen. In the event
of a frontal collision, the more the
seat is reclined, the greater the risk
of personal injury.
1. SEAT POSITION AND SEAT CUSHION

Releasing the switch will stop the seat at
that position.
Do not place anything under the front
seats, as this might interfere with the seat
movement. 2. SEATBACK ANGLE ADJUSTING SWITCH
Move the control switch in the desired
direction.
Releasing the switch will stop the seat-
back at that position.

seatback forward slightly.
CAUTION
When returning the seatback to the
upright position, observe the follow-
ing precautions in order to prevent
personal injury in a collision or sud-
den stop:
Make sure the seatback is securely
locked by pushing forward and rear-
ward on the top of the seatback.
Failure to do so will prevent the
seat belt from operating properly.
Make sure the seat belts are not
twisted or caught in the seatback
and are arranged in their proper
position and are ready to use.

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.

Injured person. Toyota recommends the
use of a seat belt. Depending on the inju-
ry, first check with your doctor for specific
recommendations.
CAUTION
Persons should ride in their seats
properly wearing their seat belts
whenever the vehicle is moving.
Otherwise, they are much more likely
to suffer serious bodily injury or
death in the event of sudden braking
or a collision.
When using the seat belts, observe
the following:
Use the belt for only one person at
a time. Do not use a single belt for
two or more people—even children.
Avoid reclining the seatbacks too
much. The seat belts provide maxi-
mum protection when the seatbacks
are in the upright position. (Refer
to the seat adjustment instructions.)
Be careful not to damage the belt
webbing or hardware. Take care that
they do not get caught or pinched
in the seat or side doors.
Inspect the belt system periodically.
Check for cuts, fraying, and loose
parts. Damaged parts should be re-
placed. Do not disassemble or
modify the system.
Keep the belts clean and dry. If
they need cleaning, use a mild soap
solution or lukewarm water. Never
use bleach, dye, or abrasive clean-
ers—they may severely weaken the
belts. (See “Cleaning the interior”
in Section 5.)
Replace the belt assembly (includ-
ing bolts) if it has been used in a
severe impact. The entire assembly
should be replaced even if damage
is not obvious.Adjust the seat as needed (front seats
only) and sit up straight and well back
in the seat. To fasten your belt, pull it
out of the retractor and insert the tab
into the buckle.
You will hear a click when the tab locks
into the buckle.
The seat belt length automatically adjusts
to your size and the seat position.
The retractor will lock the belt during a
sudden stop or on impact. It also may
lock if you lean forward too quickly. A
slow, easy motion will allow the belt to
extend, and you can move around freely.

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
Access cab models
Seat belts with an adjustable shoulder
anchor—
Adjust the shoulder anchor position to
your size.
Standard cab models—
To raise: Slide the anchor up.
To lower: Push in the lock release button
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.

Keep as low on
hips as possible
Adjust the position of the lap and
shoulder belts.
Position the lap belt as low as possible
on your hips—not on your waist, then ad-
just it to a snug fit by pulling the shoulder
portion upward through the latch plate.
CAUTION
Both highpositioned lap belts and
loosefitting belts could cause seri-
ous injuries due to sliding under
the lap belt during a collision or
other unintended result. Keep the
lap belt positioned as low on hips
as possible.
For your safety, do not place the
shoulder belt under your arm.
To release the belt, press the bucklere-
lease button and allow the belt to re-
tract.
If the belt does not retract smoothly, pull
it out and check for kinks or twists. Then
make sure it remains untwisted as it re-
tracts.
