IMPORTANT INFORMATIONABOUT YOUR LEXUS
Occupant restraint systems
Lexus encourages you and your family to take the time to read
Section 1 −6 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 −6 of this Owner’s Manual is the most important
Section for you and your family to read.
Section 1− 6 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 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 s
ystems is to help reduce
the possibility of death or serious injury in the event of a
collision. None of these systems, either individually 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.
In order to be effective, the SRS airbags must deploy with
tremendous speed. The rapid deployment of the SRS airbags
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 instructions in Section 1 −6 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 family in the event of an accident.

IMPORTANT INFORMATION ABOUT YOUR LEXUS
4Lexus recommends you to read
the provisions in Section 1−6
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 certain
aspects of your vehicle. These computers assist in driving and
maintaining optimal vehicle performance. Besides 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 contain 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.
Lexus will not disclose the data recorded in an EDR to a third
party except when:
 An agreement from the vehicle’s owner (or the leasing
company for a leased vehicle) is obtained
 Officially requested by the police or other authorities
 Used as a defense for Lexus in a law suit
 Ordered by the court

KEYS AND DOORS
xii
Flat key
As a transponder chip is built in its key case, you can start
the engine with this key.
The flat key works in every lock.
A transponder chip for engine immobilizer system has been
placed in the key case of the flat key. This chip is needed to
enable the system to function correctly, so be careful not to lose
this key. If you make your own duplicate key, you will not be
able to cancel the system or start the engine.
Insert your key plate in its key case as shown. We recommend
that you always carry this with you for emergency use. Do not
leave it in your vehicle.
Starting the engine using a flat key
1. Remove the key plate from the key case.
2. Insert the key plate into the ignition switch. The indicator
light keeps flashing.
3. Bring the key case closer to the ignition switch within 10
seconds as indicated by the arrow head. The indicator light
goes out. This means the engine immobilizer system is
automatically canceled. (For details, see “Engine immobilizer
system” on page xv.) You can put the key case away then. You
cannot cancel the engine immobilizer system if 10 seconds
have past after you ins erted the key plate. You need to remove
the key plate from the ignition switch and try it again from the
step 2.
4. Start the engine within 20 seconds after the security
indicator light goes out. You cannot start the engine if 20
seconds have past after the security indicator went off. You
need to remove the key plate from the ignition switch and try
it again from the step 2.

KEYS AND DOORS
xv
ENGINE IMMOBILIZER SYSTEM
Type A
Type B The engine immobilizer system is a theft prevention
system. When you insert the key in the ignition switch, the
transponder chip in the key’
s head transmits an electronic
code to the vehicle. The engine will start only when the
electronic code in the chip corresponds to the registered
ID code for the vehicle.
The system is automatically set when the key is removed from
the ignition switch. At this time, the security indicator light
flashes. When you insert the key in the ignition switch, the
security indicator light goes out and the system is canceled
automatically, which enables the engine to start.
For your Lexus dealer to make you a new key with built −in
transponder chip, your dealer will need your key number and
master key. However, there is a limit to the number of
additional keys your Lexus dealer can make for you.
If you make your own duplicate key, you will not be able to
cancel the system or start the engine.
