IMPORTANT INFORMATION ABOUTYOUR 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 systems 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.
Lexus 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 records 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
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
However, if necessary Lexus will:

Use the data for research on Lexus vehicle safety
performance

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 identification
information to a non±Lexus organization for research
purposes

This vehicle should not be modified with non±genuine Lexus
products. Modification with non±genuine Lexus products
could af
fect its performance, safety or durability, and may even
violate governmental regulations. In addition, damage or
performance problems resulting from the modification may not
be covered under warranty.
Spark ignition system of your Lexus
The spark ignition system in your Lexus meets all
requirements of the Canadian Interference±Causing
Equipment Standard.
Installation of a mobile two±way radio system
As the installation of a mobile two±way radio system in your
vehicle could affect electronic systems such as the multiport
fuel injection system/sequential multiport fuel injection system,
cruise control system, anti±lock brake system, SRS airbag
system and seat belt pretensioner system, be sure to check
with your Lexus dealer for precautionary measures or special
instructions regarding installation.
Tires and loading on your Lexus
Underinflated or overinflated tire pressure and the
excess load may result in the deterioration of steering
ability and braking ability, leading to an accident. Check
the tire inflation pressure periodically and be sure to
keep the load limits given in this Owner's Manual. For
details about tire inflation pressure and load limits, see
pages 351 and 274.
Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your
Lexus contain explosive chemicals. If the vehicle is scrapped
with the airbags and seat belt pretensioners left as they are,
this may cause an accident such as fire. Be sure to have the
systems of the SRS airbag and seat belt pretensioner removed
and disposed of by a qualified service shop or by your Lexus
dealer before you scrap your vehicle.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
51
(b) Driver's Seat Belt Reminder Light andBuzzer
The light and buzzer acts as a reminder to buckle up the
driver's seat belt.
Once the ignition key is turned to ªONº or ªSTARTº, the
reminder light flashes and buzzer sounds if the driver's seat
belt is not fastened. Unless the driver fastens the belt, the light
continues flashing and the buzzer stops after about 4 to 8
seconds.
(c) Front Passenger's Seat Belt ReminderLight
The light acts as a reminder to have the front passenger buckle
up the seat belt.
Once the ignition key is turned to ªONº or ªSTARTº, the
reminder light flashes if a passenger sits in the front passenger
seat and does not fasten the seat belt. Unless the front
passenger fastens the belt, the light stays flashing. However,
if a front passenger uses an additional seat cushion, the light
may not flash even when the seat belt is not buckled up.
If luggage or other load is placed on the front passenger seat,
depending on its weight and how it is placed on the seat,
built±in sensors in the seat cushion may detect the pressure,
causing the reminder light to flash.
(d) SRS Warning Light
The indicator comes on when the ignition key is turned to
the ªACCº or ªONº position. It goes off after about 6
seconds. This means the SRS airbags and front seat belt
pretensioners are operating properly.
The SRS warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensors, front seat belt pretensioner assemblies, inflators,
warning light, interconnecting wiring and power sources.
If either of the following conditions occurs, this indicates a
malfunction somewhere in the components monitored by the
warning light system. Contact your Lexus dealer as soon as
possible to service the vehicle.
 The light does not come on when the ignition key is turned
to the ªACCº or ªONº position or remains on for more than 6 seconds or flashes.
 The light comes on or flashes while driving.
If the light stays on, it indicates that the driver and front
passenger airbags fail. If the light flashes, the side and curtain
shield airbags and/or seat belt pretensioners fail.

SEATS
While the vehicle is being driven, all vehicle occupants should
have the seatback upright, sit well back in the seat and properly
wear the seat belts provided.
CAUTION
Do not drive the vehicle unless the occupants are
properly seated. Do not allow any passengers to sit
in the luggage compartment or cargo area. Persons
not properly seated and/or not properly restrained by
seat belts can be severely injured in the event of
emergency braking or a collision.
 During driving, do not allow any passengers to stand
up or move around between seats. Otherwise, severe
injuries can occur in the event of emergency braking
or a collision.
FRONT SEATS
(POWER TYPE)
Front seat precautions
Driver seat
CAUTION
The SRS driver airbag deploys with considerable force,
and can cause death or serious injury especially if the
driver is very close to the airbag. The National Highway
Traffic Safety Administration (ªNHTSAº) advises:
Since the risk zone for driver airbag is the first 50Ð75
mm (2Ð3 in.) of inflation, placing yourself 250 mm (10
in.) from your driver airbag provides you with a clear
margin of safety. This distance is measured from the
center of the steering wheel to your breastbone. If you
sit less than 250 mm (10 in.) away now, you can change
your driving position in several ways:
 Move your seat to the rear as far as you can while still
reaching the pedals comfortably.

OCCUPANT RESTRAINT SYSTEMS

Slightly recline the back of the seat. Although vehicle
designs vary, many drivers can achieve the 250 mm
(10 in.) distance, even with the driver seat all the way
forward, simply by reclining the back of the seat
somewhat. If reclining the back of your seat makes it
hard to see the road, raise yourself by using a firm,
non±slippery cushion, or raise the seat if your vehicle
has that feature.
 If your steering wheel is adjustable, tilt it downward.
This points the airbag toward your chest instead of
your head and neck.
The seat should be adjusted as recommended by
NHTSA above, while still maintaining control of the foot
pedals, steering wheel, and your view of the instrument
panel controls.
Front passenger seat
CAUTION
The SRS front passenger airbag also deploys with
considerable force, and can cause death or serious
injury especially if the front passenger is very close to
the airbag. The front passenger seat should be as far
from the airbag as possible with the seatback adjusted,
so the front passenger sits upright.
Front seats
CAUTION
The SRS side airbags are installed in the driver and front
passenger seats. Observe the following precautions.
 Do not lean against the front door when the vehicle
is in use, since the side airbag inflates with
considerable speed and force. Otherwise, you may
be killed or severely injured.
 Do not use seat accessories which cover the area
where the side airbags inflate. Such accessories may
prevent the side airbags from activating correctly,
causing death or serious injury.
 Do not modify or replace the seats or upholstery of
the seats equipped with side airbags. Such change
may prevent the side airbag system from activating
correctly, disable the system, or cause the side
airbags to inflate accidentally, resulting in death or
serious injury.

CAUTION
To avoid serious injury:
Do not set up the seatback table while the vehicle is
moving.
 Do not sit on the folded seatback.
 Make sure the front passenger's seat is securely
locked in sliding position when you set the front pas-
senger's seat as a temporary table.
NOTICE
To prevent damage to the seat, avoid putting heavy
loads on the temporary table.
