How do you reset the mileage on a IS 250 Lexus?

To reset the mileage on a Lexus IS 250, you typically need to reset the trip odometer. Start by turning on the ignition without starting the engine. Then, locate the trip meter button on the instrument panel; press and hold this button until the trip meter resets to zero. This will not change the total mileage but will reset the trip odometer for tracking purposes.
