2003 Model Year GX 470
Rear Air Suspension Special Service Campaign Notice
Dear GX470 Owner:
Lexus is dedicated to the “Passionate Pursuit of Perfection.”
As part of our constant efforts to provide you with the best in customer satisfaction and vehicle quality,
Lexus is announcing a Special Service Campaign that includes your GX 470 vehicle.
What is the problem?
In certain early 2003 model year GX 470 vehicles equipped with Rear Adjustable Height Control, if
the vehicle becomes stuck on steep off-road conditions and repeated attempts to move the vehicle
are made, excessive driving force may be applied to the driveline system. The excessive force may
cause the pin on the bottom of the air suspension pneumatic cylinder (air suspension) assembly to
break. If this occurs, the bottom of the air suspension may slide off the spring base on the rear axle.
What will Lexus do?
Before you are inconvenienced by these symptoms, Lexus would like to replace the pin with an
improved one. Any Lexus dealer will conduct this service at NO COST to you.
What should you do?
To ensure that the dealer has the correct parts in stock, please contact your local authorized Lexus
dealer and schedule an appointment to have the repairs performed.
The labor time for this repair will take approximately 90 minutes. However, depending upon the
dealer’s work schedule, it may be necessary to make your vehicle available for a longer period of
time.
Please present this notice to the dealer when you bring the vehicle in for your service
appointment.
If you no longer own the vehicle, please indicate so on the enclosed postage-paid form, providing us
with the name and address of the new owner.
What if you have other questions?
Please contact any Lexus dealer or call the Lexus Customer Assistance Center
at 1-800-255-3987.
We have sent this notice in the interest of your continued satisfaction with our products, and we
sincerely regret any inconveniences this condition may have caused you.
Sincerely,

LEXUS DIVISION
TOYOTA MOTOR SALES, U.S.A., INC.
