Head restraints
Ty p e A
Ty p e B
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.
On some models, you can also move the
head restraint forward or backward. If
such adjustment is desired, pull or push
the head restraint.
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.
Armrests
To use the armrest, pull it down as
shown above.
NOTICE
To prevent damage to the armrest,
avoid putting heavy loads on it.

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.
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.
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.
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 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 Part 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 and sit up
straight and well back in the seat. To
fasten your belt, pull it out of the re-
tractor 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 chapter.) 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.

Seat belts with an adjustable shoulder
anchor—
Adjust the shoulder anchor position to
your size.
To raise: Slide the anchor up.
To lower: Push in the lock release button
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
serious injuries in a collision.

shoulder belts.

on your hips—not on your waist, then ad-

portion upward through the latch plate.

CAUTION
High−positioned lap belts and
loose−fitting belts both could cause
serious injuries due to sliding un-
der 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 buckle−re-
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.RIGHT SIDE SEAT BELT FOR SECOND
BENCH SEAT
The second right side seat belt is a
3−point type restraint with 2 buckles. Both
seat belt buckles must be correctly lo-
cated and securely latched for proper op-
eration.
Make sure the buckle 1 is securely
latched for ready use of the second right
side seat belt.

end so that the belt is not buckled in the
wrong place.

cave end tab

CAUTION
Make sure the both buckles are cor-
rectly located and securely latched.
