2 Answers
The method to reset the Sienna maintreqd light (maintenance reminder light) is as follows: 1. Turn the ignition switch to ON and then to OFF; press and hold the trip meter reset button on the instrument cluster. 2. Turn the ignition switch to ON, at which point the maintreqd oil change light will first illuminate for 3 seconds, then flash for 2 seconds, and finally turn off after staying on for 1 second. 3. Additional information: The Sienna is a business-oriented vehicle launched by Toyota in 2011; the Toyota Sienna comes in Standard and Luxury trims, with main configuration differences including power sliding doors, roof rails, multi-function steering wheel, chrome mirrors, and front power seat adjustment.
I have a Sienna owner friend whose car also frequently has that maintenance reminder light on. Generally, when this light comes on, it's a reminder to change the oil or perform routine maintenance. To reset it, it's best to complete the maintenance work first; otherwise, you're just masking the issue. The specific method: After parking and turning off the engine, wait for the dashboard to cool down, then press and hold the ODO/Trip button without releasing for about 5 to 10 seconds until the light flashes and turns off. I've driven the Sienna a few times, and this button is easy to find on the left side of the steering wheel or on the dashboard. Remember, the light is triggered by the electronic reminder system, set to activate every 5,000 kilometers or so. Regular maintenance can extend the engine's lifespan. Ignoring it may lead to minor issues accumulating into major repairs—I've experienced this firsthand and now make it a habit to address it promptly.
