TURN OFF SEATBELT CHIME:
1) Turn the car on but do not start the engine, keep foot off brake. Cycle your trip reset button until it reads ODO. Turn ignition back off and wait a few seconds.
2) Make sure seatbelt is not fastened.
3) Turn the ignition back on, but do not start the car, keep foot off brake. As soon as you see everything light up, press and hold the trip reset button and do a long 12 second count.
4) Keep your finger on the trip reset button! Fasten your seat belt. As soon as you fasten the seat belt you should see the ODO display go from XXXX miles to "b-on". At that time take your finger off of the trip reset button and press it again. It should cycle to "b-off". Turn off ignition and you are done.

The 3.5 liter V6 engine in a 2007 Lexus RX350 has a timing CHAIN
chain i work at engine rebuilding company we are doin one as we speak
In 2010 Lexus RX350's started using Timing Chain's in the 3.5 engine, which require no maintenance (unless very high mileage is reached or parts failure). Earlier years <2009 had timing belts. I verified the 2010 model has a timing chain via contacting a local Lexus parts department.
The RX 350 has a Timing chain, not a belt. (The 330 had a belt). With proper care and maintenance on your engine, it should last a long long time... but I would plan to replace @ 150,000. It will eventually wear out..
Just go to shhding.com Problem solved!
Try buckling the belt...which you should be doing regardless of whether a buzzer tells you to.
It is integral in the BCM; can't be disabled.
Disconnect electrical connector under driver seat that connects to seat belt device.
There are two wires under the seat responsible for the seat belt alarm. You can play with them to disable. If during the state inspection they will find out that you disconnect it again they will make you to connect it again you will not pass the inspection.
look for the wire on the seat belt and follow it until you find where it plugs in under the seat and disconnect it.

There is a timing belt on the Lexus ES300 2003.
