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.
Rear center head restraint—When an oc-
cupant sits on the rear center seat, al-
ways pull up the rear center head re-
straint to the lock position.
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”
on page 74 for details.
If a child is too large for a child restraint
system, the child s hould 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 any children 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. Holding a child in your arms
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.

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” on page 74 in this Section.) To
free the belt again, fully retract the belt
and then pull the belt out once more.
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.
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, because
it cannot protect an adult occupant
or your child from death or serious
injury.

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 adjust
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 event. Keep the
lap belt positioned as low on hips
as possible.
Do not place the shoulder belt un-
der your arm.

REAR CENTER SEAT BELT
The rear center seat belt is a 3−point type
restraint with 2 buckles. Both seat belt
buckles must be correctly located and se-
curely latched for proper operation.
Make sure buckle 1 is securely latched
for ready use of the center seat belt.
PS13521
Two buckles and tabs for rear center
seat belt
The two tabs have different shapes to pre-
vent the belt from being buckled in the
wrong place.
Buckle 1—Matches the tab with the
hooked end
Buckle 2—Matches the tab with the
concave end
CAUTION
Make sure the both buckles are cor-
rectly located and securely latched.
Failure to properly match the buckle
and tab may cause serious injury in
case of an accident or a co llision.

Make sure the “AIRBAG ON”
indicator light is illuminated when
using the seat belt extender for the
front passenger seat. If the
“AIRBAG 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 “AIRBAG ON”
indicator light is illuminated. If you
use the seat belt extender while the
“AIRBAG OFF” indicator light is
illuminated, the front passenger
airbag and side airbag on the front
passenger side may not activate
correctly, causing death or serious
injury in the event of collision.
Be sure to wear the seat belt with-
out the seat belt extender if you
can fasten the seat belt without the
extender.
Do not use the seat belt extender
when installing a child restraint
system on the front or rear passen-
ger seat. If installing a child re-
straint system with the seat belt
extender connected to the seat belt,
the seat belt will not securely hold
the child restraint system, which
could cause death or serious injury
to the child or other passengers in
the event of collision.
LS13092
To connect the extender to the seat
belt, insert the tab into the seat belt
buckle so that the “PRESS” signs on
the buckle release buttons of the ex-
tender and the seat belt are both facing
outward as shown.
You will hear a click when the tab locks
into the buckle.
When releasing the seat belt, press on
the buckle release button on the extender,
not on the seat belt. This helps prevent
damage to the vehicle interior and extend-
er itself.

The seat belt pretensioner system con-
sists mainly of the following components
and their locations are shown in the il-
lustration.1. Front airbag sensors
2. SRS warning light
3. “AIRBAG ON” and “AIRBAG OFF” indi- cator lights
4. Front passenger ’s seat belt buckle switch
5. Front passenger occupant classification system (ECU and sensors)
6. Seat belt pretensioner assemblies
7. Airbag sensor assembly The seat belt pretensioners are controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor.
When the seat belt pretensioners are acti-
vated, an operating noise may be heard
and a small amount of non
−toxic gas may
be released. This does not indicate that
a fire is occurring. This gas is normally
harmless.
Once the seat belt pretensioners have
been activated, the seat belt retractors
remain locked.CAUTION
Do not modify, remove, strike or open
the seat belt pretensioner assemblies,
airbag sensor or surrounding area or
wiring. Failure to follow these instruc-
tion may prevent the seat belt preten-
sioners from activating correctly,
cause sudden operation of the system
or disable the system, which could
result in death or serious injury. Con-
sult your Toyota dealer about any re-
pair and modification.
NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can
interfere with proper operation of the
seat belt pretensioners in some
cases.
 Installation of electronic devices
such as a mobile twoway radio,
cassette tape player or compact
disc player
 Repairs on or near the front seat
belt retractor assemblies
 Modification of the suspension sys-
tem
 Modification of the front end struc-
ture
 Attachment of a grille guard (bull
bar, kangaroo bar, etc.), snowplow,
winches or any other equipment to
the front end
 Repairs made on or near the front
fenders, front end structure or con-
sole

CAUTION
The SRS front airbag system is de-
signed only as a supplement to the
primary protection of the driver and
front passenger seat belt systems.
The driver and front passenger can
be killed or seriously injured by the
inflating airbags if they do not wear
the available seat belts properly.
During sudden braking just before
a collision, an unrestrained driver
or front passenger can move for-
ward 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 in-
structions and precautions concern-
ing the seat belt system, see “Seat
belts” on page 42 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. Toyota
strongly recommends that all in-
fants and children be placed in the
rear seat of the vehicle and proper-
ly restrained. The rear seat is the
safest for infants and children. For
instructions concerning the installa-
tion of a child restraint system, see
“Child restraint” on page 74 in this
Section.The SRS airbags are designed to deploy
in severe (usually frontal) collisions
where the magnitude and duration of
the forward deceleration of the vehicle
exceeds the designed threshold level.
The SRS airbags will deploy if the severi-
ty of the impact is above the designed
threshold level, comparable to an approxi-
mate 25 km/h (15 mph) collision when the
vehicle has the impact straight into a fixed
barrier that does not move or deform.
However, this threshold velocity will be
considerably higher if the vehicle strikes
an object, such as a parked vehicle or
sign pole, which can move or deform on
impact, or if the vehicle is involved in an
underride collision (e.g. a collision in
which the front of the vehicle “underrides”,
or goes under, the bed of a truck, etc.).
It is possible that in some collisions
where the forward deceleration of the ve-
hicle is very close to the designed thresh-
old level, the SRS airbags and the seat
belt pretensioners may not activate toge-
ther.
Always wear your seat belts properly.

Collision from the rear
Collision from the side Vehicle rollover
The SRS airbags are not generally de-
signed to inflate if the vehicle is in-
volved in a side or rear collision, if it
rolls over, or if it is involved in a low
speed frontal collision. But, when
ever a
collision of any type causes sufficient
forward deceleration of the vehicle, de-
ployment of the SRS airbags may oc-
cur.

The SRS airbags may also deploy if a
serious impact occurs to the underside
of your vehicle. Some examples are
shown in the illustration.
