IMPORTANT INFORMATION ABOUT YOUR LEXUS
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.

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 338.
ENGINE OIL PRESSURE GAUGE
13X623
 1
Normal driving 2Idling
The engine oil pressure gauge indicates engine oil
pressure when the ignition is on. Check it while driving to
make sure the needle is in the proper range.
If the engine oil pressure should stay below the normal range,
pull off the road to a safe place and stop the engine
immediately. Call a Lexus dealer or qualified repair shop for
assistance.
Engine oil pressure may not build up when the engine oil level
is too low. The engine oil pressure gauge is not designed to
indicate engine oil level, and the engine oil level must be
checked using the level dipstick.

(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.
The SRS warning light system monitors the airbag sensor
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 passenger occupant cassification system and indicator
light, front passenger seat belt buckle switch, inflators, seat
belt pretensioners, roll sensing of curtain shield airbags off
indicator 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.
The SRS warning light will come on and front passenger
occupant classification indicator light will indicate “OFF” if
there is a malfunction in the front passenger occupant
classification system.
(e) Engine Oil Replacement Reminder Light (U.S.A. only)
The light acts as a reminder to replace the engine oil.
This light will come on when the ignition key is turned to “ON”
and will go off after about a few seconds.
When you drive for about 7200 km (4500 miles) after the
engine oil replacement, this light illuminates for about 3
seconds and then flashes for about 12 seconds with the
ignition key turned to “ON” position. If you continue driving
without the engine oil replacement, and if the driving range
exceeds 8000 km (5000 miles), the light will come on after the
ignition key is turned to “ON” position. The light will remain on\
thereafter.
If the light is flashing, we recommend that you replace the
engine oil at an early opportunity depending on the driving and
road condition. If the light comes on, replace it as soon as
possible.
You need to reset the light after the engine oil replacement.
Reset the light by following the procedure below:
1. Turn the ignition key to th e “LOCK” position with the
odometer re ading shown. (For details, see “Odometer and trip
meter” on page 51.)
2. Turn the ignition key to the “ON” position while holding down
the “ODO/TRIP” knob.
Hold down the knob until the light goes off. Before the light
goes off, it illuminates for 3 seconds, flashes for 2 seconds and
