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 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.

SWITCHES
34
The automatic light control sensor is on top of the driver's side
instrument panel.
Do not place anything on the instrument panel, and/or do not
affix anything on the windshield to block this sensor.
When the headlights are on, they automatically turn off about
30 seconds after any side door is opened and closed with the
ignition key turned to the ªACCº or ªLOCKº position.* If you
want to turn off the lights immediately, push the ªLOCKº button
on the wireless remote control key twice. The lights also can
be turned off immediately by pushing the ªLOCKº button on the
wireless remote control key with all the doors locked.
NOTE:* The time before turning off the lights can be changed.Ask your Lexus dealer for details.
If any of the side door is kept opened, the lights automatically
turn off after 30 minutes.
When the headlight switch is on with all the doors locked,
pushing the ªLOCKº button on the wireless remote control key
turns off the headlights.
If you are going to park for over one week, make sure the
headlight switch is off.
Daytime Running Light System
The daytime running light system make your front turn signal
lights turn on when the parking brake is released with the
engine started and the headlights are turned off. They will not
go off until the ignition switch is turned off.

STARTING AND DRIVING
444
Driving over the steps such as the joints on the road.
 Driving on roads where the road surface is pitted or
has other differences in surface height.
Install all 4 tires of specified size at appropriate
pressure: The anti±lock brake system detects vehicle
speeds using the speed sensors for respective wheels'
turning speeds. The use of tires other than specified
may fail to detect the accurate turning speed resulting
in a longer stopping distance.ªABSº warning light

1U.S.A.2Canada
The light comes on when the ignition key is turned to the ªONº
position. If the anti±lock brake system and the brake assist
system work properly, the light turns off after a few seconds.
Thereafter, if either of the systems malfunctions, the light
comes on again.
When the ªABSº warning light is on (and the brake system
warning light is off), the anti±lock brake system, the brake
assist system, the active traction control system and the
vehicle stability control system do/does not operate, but the
brake system still operates conventionally.
When the ªABSº warning light is on (and the brake system
warning light is off), the anti±lock brake system does not
operate so that the wheels could lock up during a sudden
braking or braking on slippery road surfaces.
