IMPORTANT INFORMATION ABOUT YOUR LEXUS
iii
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

GAUGES, METERS AND SERVICE REMINDER INDICATORS
85
(b) Driver’s Seat Belt Reminder Light andBuzzer
The light and buzzer act as a reminder to have the driver buckle
up the seat belt.
Once the ignition switch is turned to “ON” or “START”, 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 switch is turned to “ON” or “START”, 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 continues flashing.
However, if a front passenger uses an additional seat cushion,
the indicator 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, the
built−in sensor in the seat cushion may detect the pressure,
causing the reminder light to flash.
(d) SRS Warning Light
The indicators come on when the ignition switch is turned
to the “ON” position. It goes off after about 6 seconds.
This means the SRS airbags and seat belt pretensioners
are operating properly.
This warning light system monitors the airbag sensor
assembly, front airba g sensors, side and curtain shield airbag
sensor assemblies, curtain shield airbag sensor assemblies,
driver’s seat position sensor, driver’s seat belt buckle switch,
occupant detection sensor, front passenger’s seat belt buckle
switch, seat belt pretensioner assemblies, inflators, warning
light, interconnecting wiring and power sources.
If any of the following conditions occurs, this indicates a
malfunction somewhere in the parts monitored by the warning
light system. Contact your Lexus dealer as soon as possible
to service the vehicle.
 When the ignition switch is turned to the “ON” position, the
light does not come on or remains on for more than 6
seconds.
 The light comes on while driving.
If the light stays on, it indicates that the SRS driver and front
passenger airb ags, SRS side and curtain shield airbags and/or
seat belt pretensioners have a problem.

11Front airbag sensors
The SRS front airbag system consists mainly of the above
components, and their locations are shown in the illustration.
The airbag sensor assembly consists of a safing sensor and
airbag sensors. The front airbag sensors constantly monitor the forward
deceleration of the vehicle. If an impact results in a forward
deceleration beyond the designed threshold level, the system
triggers
the airbag inflators. At this time a chemical reaction in
the inflators very quickly fills the airbags with non−toxic gas to
help restrain the forward motion of the occupants. The front
airbags then quickly deflate, so that there is no obstruction of
the driver’s vision should it be necessary to continue driving.
When the airbags inflate, they produce a loud noise and
release some smoke and residue along with non −toxic gas.
This does not indicate a fire. This smoke may remain inside
the vehicle for some time, and may cause some minor irritation
to the eyes, skin or breathing. Be sure to wash off any residue
as soon as possible to prevent any potential skin irritation with
soap and water. If you can safely exit from the vehicle, you
should do so immediately.

In a severe side impact, the side and curtain shield airbag
sensor and/or the curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain shield airbag inflators.
At this time a chemical reaction in the inflators quickly fills the
airbags with non
−toxic gas to help restrain the lateral motion
of the occupants.
When the airbags inflate, they produce a fairly loud noise and
release some smoke and residue along with non −toxic gas.
This does not indicate a fire. This smoke may remain inside
the vehicle for some time, and may cause some minor irritation
to the eyes, skin or breathing. Be sure to wash off any residue
as soon as possible to prevent any potential skin irritation with
soap and water. If you can safely exit from the vehicle, you
should do so immediately.
Deployment of the airbags happens in a fraction of a second,
so the airbags must inflate with considerable force. While the
system is designed to reduce serious injuries, it may also
cause minor burns or abrasions and swelling.
Front seats as well as parts of the front and rear pillars, and roof
side rail may be hot for several minutes, but the airbags
themselves will not be hot. The airbags are designed to inflate
only once.
CAUTION
SRS side airbags and curtain shield airbags inflate with
considerable force. To reduce the possibility of death
or serious injury when they inflate, the driver, front
passenger and rear outboard passengers must:
 Wear their seat belts properly.
 Remain properly seated with their backs upright and
against the seats at all times.

Move seat fully back
CAUTION
 A forwardfacing child restraint system should be
allowed to be installed on the front passenger seat
only when it is unavoidable. Always move the seat as
far back as possible, because the front passenger
airbag could inflate with considerable speed and
force. Otherwise, the child may be killed or seriously
injured.
 Do not allow the child to lean his/her head or any part
of his/her body against the door or the area of the
seat, front or rear pillar or roof side rail from which the
side airbags or curtain shield airbags deploy even if
the child is seated in a child restraint system. It is
dangerous if the side airbag and curtain shield airbag
inflate, and the impact could cause death or serious
injury to the child.

1. Sit the child on a booster seat. Run the lap and shoulder belt
through or around the booster seat and across the child
following the instructions provided by its manufacturer and
insert the tab into the buckle taking care not to twist the belt.
Make sure the shoulder belt is correctly across the child’s
shoulder and that the lap belt is positioned as low as possible
on the child’s hips. See “Seat belts” on page 168 for details.
CAUTION
 Always make sure the shoulder belt is positioned
across the center of child’ s shoulder. The belt should
be kept away from child’s neck, but not falling off
child’s shoulder. Otherwise, the child may be killed
or seriously injured in case of sudden braking or a
collision.

FUEL PUMP SHUT OFF
SYSTEM323.
The fuel pump shut off system stops supplying fuel to the
engine to minimize the risk of fuel leakage when the engine
stalls or an airbag inflates upon collision. To restart the engine
after the fuel pump shut off system activates, turn the ignition
switch to “ACC” or “LOCK” once and start it.
CAUTION
Inspect the ground under the vehicle before restarting
the engine. If you find that liquid has leaked onto the
ground, it is the fuel system that has been damaged and
it is in need of repair. In this case, do not restart the
engine.

3. Wax the vehicle again when water does not bead but
remains on the surface in large patches.
373.CLEANING THE INTERIOR
CAUTION

Be careful not to splash water or spill liquid on the
floor. This may prevent the side airbags from
activating correctly, resulting in serious injury.
 Do not wash the vehicle floor with water, or allow
water to get onto the floor when cleaning the vehicle
interior or exterior. Water may get into audio
components or other electrical components above or
under the floor carpet (or mat) and cause a
malfunction; and it may cause body corrosion.
Leathertrimmed interior
The selected leather is used in your Lexus. Due to
characteristics of leather products, some parts of leather may
be rough, uneven or scratched originally.
To keep good appearance, we recommend you to clean it
periodically twice a year.
Remove dirt on the leather in the following ways:
1. Wipe it off lightly using a soft cloth (e.g. gauze) dampened
with 5% solution of neutral detergent for wool. 2. Wring water from a clean cloth and thoroughly wipe off all
traces of detergent with it.
3. Wipe off
the surface of the leather with a dry soft cloth. Allow
the leather to dry in a ventilated shaded area. Excess of wet
may cause the hardening or shrinking of the leather.
NOTICE
 Dirt or sand adhered to the leather may damage the
treated surface and cause it to wear earlier. Remove
dirt or sand using a vacuum cleaner.
 If a stain should fail to come out with a neutral
detergent, apply a cleaner that does not contain an
organic solvent.
 Never use organic substances such as benzine,
alcohol or gasoline, or alkaline or acid solutions for
cleaning the leather as these could cause
discoloring.
 Use of a nylon brush or synthetic fiber cloth, etc. may
scratch the fine grained surface of the leather.
 Mildew may develop on soiled leather upholstery. Be
especially careful to avoid oil spots. Try to keep your
upholstery always clean.
