IMPORTANT INFORMATION ABOUT THIS MANUAL
iv
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 wh ich 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.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
71
ENGINE COOLANT
TEMPERATURE GAUGE
 Normal range
The gauge indicates the engine coolant temperature when
the ignition switch is on. The engine operating
temperature will vary with changes in weather and engine
load.
If the needle points to the red zone or higher, stop your vehicle
and allow the engine to cool. Your vehicle may overheat during severe operating conditions,
such as:

Driving up a long hill on a hot day.
 Reducing speed or stopping after high speed driving.
 Idling for a long period with the air conditioning on in
stop−and−go traffic.
 Towing a trailer.
NOTICE
Do not remove the thermostat in the engine cooling
system as this may cause the engine to overheat. The
thermostat is designed to control the flow of coolant
to keep the temperature of the engine within the
specified operating range.
 Do not continue driving with an overheated engine.
See “If your vehicle overheats” on page 499.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
77
(b) Driver’s Seat Belt Reminder Light and Buzzer
The light and buzzer act as a reminder to buckle up the driver’s
seat belt.
Once the ignition key is turned to the “ON” or “START” position,
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 Reminder Light
The light acts as a reminder to have the front passenger buckle
up the seat belt.
Once the ignition key is turned to the “ON” or “START” position,
the reminder light flashes if a passenger sits in the front
passenger seat and does not fasten the seat belt.
If luggage or other load is placed on the front passenger seat,
depending on its weight, the reminder light may flash.
(d) SRS Warning Light
The indicator comes on when the ignition key 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.

assembly, front airbag sensors, side and curtain shield airbag
sensor assemblies, curtain shield airbag sensor assemblies,
driver’s seat position sensor, driver’s seat belt buckle switch,
front pas senger occupant classification system, “AIRBAG ON”
indicator light, “AIRBAG OFF” indicator light, 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 of the airbags or seat belt pretensioners. Contact
your Lexus dealer as soon as possible.
 The light does not come on when the ignition key is turned
to the “ON” position or remains on for more than 6 seconds
or flashes.
 The light comes on or starts flashing while driving.
If the light stays on, it indicates that the driver and front
passenger airbags and/or front passenger occupant
classification system, “AIRBAG ON” indicator light and
“AIRBAG OFF” indicator light fail. If the light flashes, the side
and curtain shield airbags and/or seat belt pretensioners have
a problem.

FRONT PASSENGER OCCUPANTCLASSIFICATION SYSTEM
Your vehicle is equipped with a front passenger occupant
classification system. This system detects the conditions
1 — 4 in the table shown below, and based on these
conditions activates or deactivates the following
systems;
 Front passenger airbag
 Side airbag on the front passenger seat
 Front passenger’s seat belt pretensioner
The system monitors the weight and load on the front
passenger seat, and the seat belt buckle switch in
determining conditions 1 — 4.
In order for the system to detect the conditions correctly,
do not do any of the following:
 Apply a heavy load to the front passenger seat or equipment
(e.g. seatback pocket or armrest).
 Attach a commercial seatback table, etc. to the front
passenger seat seatback.
 Put weight on the front passenger seat by putting your
hands or feet on the seatback from the rear passenger seat.
“AIRBAG ON” and “AIRBAG OFF” indicator and front
passenger’s seat belt reminder light
SRS warning light

OCCUPANT RESTRAINT SYSTEMS
194The “AIRBAG ON” and “AIRBAG OFF” indicator lights will
be illuminated when the ignition switch is in the “ON”
position
and a child or child restraint system is in the front
passenger seat (see tablecondition 2). This indicates
that in the event of a severe frontal or passenger’s side
impact, the front passenger airbag and side airbag on the
front passenger seat are deactivated and will not deploy.
If the front passenger occupant classification system
determines that a person of adult size sits in the front
passenger seat but the “AIRBAG OFF” indicator light is
illuminated, one of the following is likely to have occurred:
 The rear passenger lifts the front passenger seat cushion
with their legs.
 Objects are placed under the front passenger seat.
 A front passenger seat seatback is in contact with a rear
seat.
To ensure the system correctly detects an adult sitting in the
front passenger seat, make sure the above do not happen.
Make sure the “AIRBAG ON” indicator light is illuminated when
an adult sits in the front passenger seat. If the “AIRBAG OFF”
indicator light is illuminated, ask the passenger to sit up
straight, well back in the seat, and with the seat belt worn
correctly. If the “AIRBAG OFF” indicator light still remains
illuminated, either ask the passenger to move to the rear seat,
or if that is not possible, move the front passenger seat fully
rearward. The “AIRBAG ON” and “AIRBAG OFF” indicator light will
be initially illuminated when the ignition switch is turned
to the “ON” position. It will remain for about four seconds
and then go off. After about two seconds, the front
passenger occupant classification system operates and
judges whether to turn the indicator light on or not.
The SRS warning light and “AIRBAG OFF” indicator light
will be illuminated if there is a malfunction in the front
passenger occupant classification system.
