You can disconnect your battery for a short period of time, 5-10 minutes should do it. There is no guarantee that the check engine light will not come back on in time, but it will make it go away at least temporarily.If you go to Autozone, 99% of the time they will hook up a code reader and diagnose your problem. It may be a minor and/or inexpensive fix. Please vote appropriately and leave feedback. I hope this helps and good luck.

This light is not programmed to a service interval, it is a fault sensor code light.
The check engine light will come on after refueling if you have a loose gas cap. It may also come on if you have an exhaust leak or a fuel mixture issue casued by one of several 02 senosrs malfunctioning .
If the issue is the gas cap often after releasing and tightening the cap your light will go out within a day or two of driving. You could also add some fuel injector cleaner.
Sometimes the lights will need to be reset with a code reading device plugged in under dash. This device will read out engine fault codes and help determine the problem are in the engine.
If you have a failed O2 sensor and continue to drive the ECU will adjust your fuel mixture in an attempt to correct the problem, so it is best to have the readout checked.
Lexus service is second to none and Lexus is not out to take your money, only to ensure a long and satisfying ownership with a top performing car. You are VERY fortunate to have an 03 with such low mileage. My 2001 RX300 has over 150,000 miles and is still going strong, same engine as yours.
