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.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 death or 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
instructions in Section 1−3 of this Owner ’s Manual will help
ensure 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 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.

The key consists of an electronic key
and a mechanical key. The mechanical
key is for emergency use. If the elec-
tronic key does not operate, you can
open the driver ’s door using the me-
chanical key.1. Electronic keys—These keys can lock or unlock all the doors and can open
the trunk by using the wireless remote
control function or entry function of the
smart key system.
2. Mechanical keys—These keys can lock or unlock the driver’s door and the
glove box. 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
lid with smart key system” on page 47
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 49
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 s
hould
maintain a reasonable distance be-
tween themselves and the smart
key system antennas, because the
radio waves may affect the opera-
tion of such devices. For the anten-
na locations see “ANTENNA LOCA-
TION” on page 34 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 38
in this Section.

Never leave anyone (particularly a
small child) alone in your vehicle,
especially with the “POWER” switch
set at ON. Otherwise, he/she could
use the power window switches and
get trapped in a window. Unat-
tended person (particularly a small
child) can be involved in a serious
accident.
When you carry the registered key into
the actuation area, the trunk can be
opened. For further information of actua-
tion area, see “Smart key system” on
page 32 in this Section.
See “—Stowage precautions” on page 295
in Section 2 for precautions when loading
luggage.
To close the trunk lid, lower it and press
down on it. After closing the trunk lid, try
pulling it up to make sure it is securely
closed.The trunk lid can be opened with the wire-
less remote control function, see “—Open-
ing trunk lid” on page 28 in this Section.
CAUTION
Keep the trunk lid closed while driv-
ing. This not only keeps the luggage
from being thrown out but also pre-
vents exhaust gases from entering
the vehicle.
A warning buzzer may sound when:
The key is brought into the cabin after
the trunk is opened, and the trunk is
then closed.
The key is near the trunk when the
trunk is closed.
The buzzer may sound even when the key
is not in the trunk. This does not indicate
a problem. However, under these circum-
stances, the trunk cannot be opened using
the smart key system. Open the trunk
using other methods.
