2006 Lexus GX470 transmission

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.

(e) Malfunction Indicator Lamp
This lamp comes on when the ignition key is turned to the
“ON” position and goes off after the engine starts. This
means that the warning light system is operating properly.
If the lamp remains on, or the lamp comes on while driving,
first check the followings.
 Empty fuel tank
If the fuel tank is empty, refuel immediately.
 Loose fuel tank cap
If the fuel tank cap is loose, securely tighten it.
These cases are temporary malfunctions. The malfunction
indicator lamp will go off after taking several driving trips.
If the lamp does not go off even after several trips, contact your
Lexus dealer as soon as possible.
If the fuel tank is not empty or the fuel tank cap is not
loose...
 There is a problem somewhere in the engine, emission
control system, electronic throttle control system, automatic
transmission electrical system or warning light system itself.
Contact your Lexus dealer as soon as possible to service the
vehicle.
If engine speed does not increase when the accelerator pedal
is depressed, there may be a problem somewhere in the
electronic throttle control system. At this time, vibration may occur. However, if you depress the
accelerator pedal more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle checked by your
Lexus dealer as soon as possible.
Even if the abnormality of the electronic throttle control system
is corrected during low speed driving, the system may not be
recovered until the engine is stopped and the ignition key is
turned to “ACC” or “LOCK” position.
CAUTION
Be especially careful to prevent erroneous pedal
operation.
Emissions inspection and maintenance (I/M) programs
Your vehicle may not pass a state emission inspection if the
malfunction indicator lamp remains on. Contact your Lexus
dealer to check your vehicle’s emission control system and
OBD (On−Board Diagnostics) system before taking your
vehicle for the inspection.
For details, see “Emissions inspection and maintenance (I/M)
programs” on page 489.
