Important information about your Toyota
Occupant restraint systems
Toyota encourages you and your family to take the time to
read Section 1−3 of this Owner’s Manual carefully. In
terms of helping you understand how you can receive the
maximum benefit of the occupant restraint systems this
vehicle provides, Section 1 −3 of this Owner ’s Manual is
the most important Section for you and your family to
read.
Section 1 −3 describes the function and operation concern-
ing seats, seat belts, SRS airbags and child restraint sys-
tems of this vehicle and some potential hazards you
should be aware of. These systems work together along
with the overall structure of this vehicle in order to provide
occupant restraint in the event of a crash. The effect of
each system is enhanced when it is used properly and
together with other systems. No single occupant restraint
system can, by itself, provide you or your family with the
equal level of restraint which these systems can provide
when used together. That is why it is important for you and
your family to understand the purpose and proper use of
each of these systems and how they relate to each other.
The purpose of all occupant restraint systems is to help
reduce the possibility of death or serious injury in the
event of a collision. None of these systems, either individ-
ually or together, can ensure that there is no injury in the
event of collision. However, the more you know about
these systems and how to use them properly, the greater
your chances become of surviving an accident without
death or serious injury.
Seat belts provide the primary restraint to all occupants of
the vehicle, and every occupant of the vehicle should wear
seat belts properly at all times. Children should always be
secured in child restraint systems that are appropriate for
their age and size. SRS (Supplemental Restraint System)
airbags are, as their names imply, designed to work with,
and be supplemental to, seat belts and are not substitutes
for them. SRS airbags can be very effective in reducing
the risk of head and chest injuries by preventing contact of
the head and chest with interior portions of the vehicle.

While the vehicle is being driven, all ve-
hicle occupants should have the seatback
upright, sit well back in the seat and prop-
erly wear the seat belts provided.
CAUTION
Do not drive the vehicle unless the
occupants are properly seated. Do
not allow any passengers to sit on
top of a foldeddown seatback, or
in the luggage compartment or car-
go area. Persons not properly
seated and/or not properly re-
strained by seat belts can be se-
verely injured in the event of emer-
gency braking or a collision.
During driving, do not allow any
passengers to stand up or move
around between seats. Otherwise,
severe injuries can occur in the
event of emergency braking or a
collision.
Driver seat
CAUTION
The SRS driver airbag deploys with
considerable force, and can cause
death or serious injury especially if
the driver is very close to the airbag.
The National Highway Traffic Safety
Administration (“NHTSA”) advises:
Since the risk zone for driver airbag
is the first 50—75 mm (2—3 in.) of
inflation, placing yourself 250 mm (10
in.) from your driver airbag provides
you with a clear margin of safety.
This distance is measured from the
center of the steering wheel to your
breastbone. If you sit less than 250
mm (10 in.) away now, you can
change your driving position in sever-
al ways:
Move your seat to the rear as far
as you can while still reaching the
pedals comfortably.
Slightly recline the back of the
seat. Although vehicle designs vary,
many drivers can achieve the 250
mm (10 in.) distance, even with the
driver seat all the way forward, sim-
ply by reclining the back of the
seat somewhat. If reclining the back
of your seat makes it hard to see
the road, raise yourself by using a
firm, nonslippery cushion, or raise
the seat if your vehicle has that
feature.
If your steering wheel is adjustable,
tilt it downward. This points the air-
bag toward your chest instead of
your head and neck.
The seat should be adjusted as rec-
ommended by NHTSA above, while
still maintaining control of the foot
pedals, steering wheel, and your view
of the instrument panel controls.

Front passenger seat
CAUTION
The SRS front passenger airbag also
deploys with considerable force, and
can cause death or serious injury es-
pecially if the front passenger is very
close to the airbag. The front passen-
ger seat should be as far from the
airbag as possible with the seatback
adjusted, so the front passenger sits
upright.
Front seats (with SRS side airbags)
CAUTION
The SRS side airbags are installed in
the driver and front passenger seats.
Observe the following precautions.
Do not lean against the front door
when the vehicle is in use, since
the side airbag inflates with consid-
erable speed and force. Otherwise,
you may be killed or seriously in-
jured.
Do not use seat accessories which
cover the area where the side air-
bags inflate. Such accessories may
prevent the side airbags from acti-
vating correctly, causing death or
serious injury.
Do not modify or replace the seats
or upholstery of the seats equipped
with side airbags. Such change may
prevent the side airbag system from
activating correctly, disable the sys-
tem or cause the side airbag sys-
tem to inflate accidentally, resulting
in death or serious injury.
CAUTION
Do not adjust the seat while the
vehicle is moving as the seat may
unexpectedly move and cause the
driver to lose control of the vehicle.
Be careful that the seat does not
hit a passenger or luggage.
After adjusting the seat position, re-
lease the lever and try sliding the
seat forward and backward to make
sure it is locked in position.
After adjusting the seatback, push
your body back against the seat to
make sure the seat is locked in
position.
Do not put objects under the seats
except for putting them in the auxil-
iary box. Otherwise, the objects
may interfere with the seatlock
mechanism or unexpectedly push
up the seat position adjusting lever
and the seat may suddenly move,
causing the driver to lose control of
the vehicle.

CAUTION
Avoid reclining the seatback any
more than needed. The seat belts pro-
vide maximum protection in a frontal
or rear collision when the driver and
the front passenger are sitting up
straight and well back in the seats. If
you are reclined, the lap belt may
slide past your hips and apply re-
straint forces directly to the abdomen
or your neck may contact the shoul-
der belt. In the event of a frontal
collision, the more the seat is re-
clined, the greater the risk of death
or personal injury.
