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, chest and knee injuries by preventing
contact of the head, chest and knee 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
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

Spare keys should not be left in the
cabin. In the event that a spare key is
left in the cabin, the smart key system
will remain actuated even after the
doors have been locked. Under these
circumstances, the trunk can be opened
even after the driver has exited and
locked the vehicle, increasing the dan-
ger of theft. (Refer to “OPENING
TRUNK WITH SMART KEY SYSTEM” on
page 46 in this Section.)
To protect items locked in the trunk or the
glove box when using valet parking, leave
the electronic key with the attendant. Keep
the mechanical key with you. For details
about locking the trunk opener switch, see
“—Luggage security system” on page 47
in this Section.
A transponder chip for engine immobilizer
system has been placed in the electronic
keys. These chips are needed to enable
the system to function correctly, so be
careful not to lose these keys.CAUTION
People with implanted pacemakers
or cardiac defibrillators should keep
away from the smart key system
antennas, because the radio waves
may affect the operation of such
devices. For the antenna locations
see “ANTENNA LOCATION” on page
32 in this Section.
Users of any electrical medical de-
vice other than implanted pacemak-
ers and implanted cardiac defibrilla-
tors should consult the manufactur-
er of the device for information
about its operation under the influ-
ence of radio waves. Radio waves
could have unexpected effects on
the operation of such medical de-
vices.
If necessary, the entry function can
be disabled. See “DISABLING THE
SMART KEY SYSTEM” on page 36
in this Section.
NOTICE
When using a electronic key contain-
ing a transponder chip, observe the
following precautions:
Do not affix any material that cuts
off electromagnetic waves (such as
a metal seal) on the electronic key.
Do not knock the electronic key
hard against other objects.
Do not leave the electronic key ex-
posed to high temperatures for a
long period, such as on the dash-
board or hood under direct sun-
light.
Do not put the electronic key in
water or wash it in an ultrasonic
washer.
Do not keep the electronic key to-
gether with the products emitting
electromagnetic waves such as a
cellular phone.

information.If the wireless remote control transmitter
does not actuate the doors, or does not
operate from a normal distance, or if the
indicator on the transmitter is dimmed or
does not come on:
Check for closeness to a radio trans-
mitter such as a radio station or an
airport which can interfere with normal
operation of the key.
The battery may have been consumed.
Check the battery in the key. To re-
place the battery, see “—Replacing bat-
tery” on pages 26 or 28 in this Sec-
tion.
If you lose your wireless remote control
key, contact your Toyota dealer as soon
as possible to avoid the possibility of
theft, or an accident. (See “If you lose
your keys” on page 356 in Section 4.)
It is possible to disable the wireless re-
mote control system. For details, contact
