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.

2006 SIENNA from March ‘06 Prod. (OM45443U)
In order to be effective, the SRS airbags must deploy with
tremendous speed. The rapid deployment of the SRS air-
bags makes the SRS airbags themselves potential sources
of serious injury if an occupant is too close to an airbag,
or if an object or some part of his or her body has been
placed between the occupant and the airbag at the time of
deployment. This is just one example of how the instruc-
tions in Section 1−3 of this Owner ’s Manual will help en-
sure proper use of the occupant restraint systems, and
increase the safety they can provide to you and your fami-
ly in the event of an accident.
Toyota recommends you to read the provisions in Section
1 −3 carefully and refer to them as needed during your time
of ownership of this vehicle.Event data recorder
Your vehicle has computers that monitor and control cer-
tain aspects of your vehicle. These computers assist in
driving and maintaining optimal vehicle performance. Be-
sides storing data useful for troubleshooting, there is a
system to record data in a crash or a near car crash
event. This is called an Event Data Recorder (EDR).
The SRS airbag sensor assembly contains the EDR. In a
crash or a near car crash event, this device may record
some or all of the following information:
 Engine speed
 Whether the brake pedal was applied or not
 Vehicle speed
 To what extent the accelerator pedal was depressed
 Position of the transmission selector lever
 Whether the driver and front passenger wore the seat
belts or not
 Driver’s seat position
 Front passenger ’s occupant classification
 SRS airbag deployment data

SRS airbag system diagnostic data
If your vehicle is equipped with a vehicle stability control
(VSC) system, its Electronic Control Unit (ECU) may con-
tain another EDR. There are a variety of driving situations
which include activating the VSC under which the VSC
EDR will record certain information. The VSC EDR may
record some or all of the following information:
 Behavior of the vehicle
 Steering wheel angle
 Vehicle speed
 To what extent the accelerator pedal was depressed
 To what extent the brake pedal was applied
 To what extent the ECU controlled the condition of
the 4 wheels
 Vehicle stability control system di agnostic data
The information above is intended to be used for the
purpose of improving vehicle safety performance. Unlike
general data recorders, the EDR does not record sound
data such as conversation between passengers.Toyota will not disclose the data recorded in an EDR to a
third party except when:
 An agreement from the vehicle’s owner (or the leas-
ing company for a leased vehicle) is obtained
 Officially requested by the police or other authorities
 Used as a defense for Toyota in a law suit
 Ordered by the court
However, if necessary Toyota will:
 Use the data for research on Toyota vehicle safety
performance
 Disclose the data to a third party for research pur-
poses without disclosing details of the vehicle owner,
and only when it is deemed necessary
 Disclose summarized data cleared of vehicle identifi-
cation information to a non −Toyota organization for
research purposes

Tires and loading on yourTo y o t a
Underinflated or overinflated tire pressure and the
excess load may result in the deterioration of
steering ability and braking ability, leading to an
accident. Check the tire inflation pressure periodi-
cally and be sure to keep the load limits given in
this Owner ’s Manual. For details about tire inflation
pressure and load limits, see pages 398 and 471.
Scrapping of your Toyota
The SRS airbag and seat belt pretensioner devices in your
Toyota contain explosive chemicals. If the vehicle is
scrapped with the airbags and pretensioners left as they
are, this may cause an accident such as fire. Be sure to
have the systems of the SRS airbag and seat belt preten-
sioner removed and disposed of by the qualified service
shop or by your Toyota dealer before you dispose of your
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 with side
airbags. Such change may prevent
the side airbag system from activat-
ing correctly, disable the system or
cause the side airbags to inflate ac-
cidentally, resulting in death or seri-
ous 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.
