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.

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 diagnostic data
The information above is intended to be used for the pur-
pose of improving vehicle safety performance. Unlike gen-
eral 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 own-
er, and only when it is deemed necessary
 Disclose summarized data cleared of vehicle identifi-
cation information to a non −Toyota organization for
research purposes
