IMPORTANT INFORMATION ABOUT YOUR LEXUS
iv
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 may record some
or all of the following information:
Gasoline 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 Electronic Control Unit (ECU) of the electronically
controlled brake (ECB) may contain another EDR. There are
a variety of driving situations which include activating the ECB
under which the ECB EDR will record certain information. The
ECB 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 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.
