buckles, retractors and anchors operate
properly and smoothly. Make sure the belt
webbing is not cut, frayed, worn or dam-
aged.
Accelerator pedal
Check the pedal for smooth operation and
uneven pedal effort or catching.
Brake pedal
Check the pedal for smooth operation and
that the pedal has the proper clearance.
Check the brake booster function.
Brakes
In a safe place, check that the brakes do
not pull to one side when applied.

found and corrected immediately.
Doors and engine hood
Check that all doors and trunk operate
smoothly and all latches lock securely.
Make sure the engine hood secondary
latch secures the hood from opening when

Occupant restraint sys-tems
Toyota encourages you and your
family to take the time to read
Section 2−2 of this Owner’s Manu-
al carefully. In terms of helping
you understand how you can re-
ceive the maximum benefit of the
occupant restraint systems this ve-
hicle provides, Section 2 −2 of this
Owner ’s Manual is the most im-
portant section for you and your
family to read.
Section 2 −2 describes the function
and operation concerning seats,
seat belts, SRS airbags and child
restraint systems of this vehicle
and some potential hazards you
should be aware of. These sys-
tems 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 oc-
cupant restraint system can, by it-
self, 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 fam-
ily to understand the purpose and
proper use of each of these sys-
tems and how they relate to each
other.
The purpose of all occupant re-
straint systems is to help reduce
the possibility of death or serious
injury in the event of a collision.
None of these systems, either in-
dividually 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 re-
straint to all occupants of the ve-
hicle, 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 ap-
propriate for their age and size.
SRS (Supplemental Restraint Sys-
tem) 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 con-
tact 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) sys-
tem, its Electronic Control Unit
(ECU) may contain another EDR.
There are a variety of driving situ-
ations 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 ped-
al was applied
 To what extent the ECU con-
trolled the condition of the 4
wheels
 Vehicle stability control sys-
tem diagnostic data
The information above is intended
to be used for the purpose of im-
proving vehicle safety perfor-
mance. Unlike general data record-
ers, 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 ve-
hicle’s owner (or the leasing
company for a leased vehicle)
is obtained
 Officially requested by the po-
lice or other authorities
 Used as a defence for Toyota
in a law suit
 Ordered by the court
However, if necessary Toyota will:
 Use the data for research on
Toyota vehicle safety perfor-
mance
 Disclose the data to a third
party for research purposes
without disclosing details of
the vehicle owner, and only
when it is deemed necessary
 Disclose summarized data
cleared of vehicle identifica-
tion information to a non −To -
yota organization for research
purposes
