Hi Forum,

"Maintenance Required" light came on in my 2016 Highlander. I followed the procedure that I found on the interwebs:

1) Put your key in the ignition. Turn the key to position one. This is the position just before starting the car.
2) Push the odometer button on the dashboard. Hold it for a second or two. Then, turn your key to position two.
3) Continue to hold the odometer button for around ten seconds. The light should flash, beep, and then go out.
4) Once off, release the odometer button. Start your car.

But no matter how many times I do it, the "Maintenance Required" light never went away!! When I took the car for an oil change the mechanics magically made it disappear, but when I asked the mechanics to teach me how to do it they laughed in my face and wouldn't tell me the secret. Rude. Will never go back to them for business!!

So, am I supposed to turn the key back to "OFF" between steps 2 and 3? What's the secret?

Thank you so much,
Damon

this is from a 2017 manual - I would assume your manual also has the info
■Resetting the message indicating maintenance is required (U.S.A. only)
After the required maintenance is performed according to the maintenance
schedule, please reset the message.
To reset the message, follow the procedure described below:
 Using the trip meter
Vehicles without a smart key system: Turn the engine switch to the “LOCK”
position with the trip meter A reading shown.
Vehicles with a smart key system: Turn the engine switch off with the trip
meter A reading shown.
Vehicles without a smart key system: While pressing the trip meter reset
button (P. 93), turn the engine switch to the “ON” position (do not start the
engine, reset mode will be canceled).
Vehicles with a smart key system: While pressing the trip meter reset button
(P. 93), turn the engine switch to the IGNITION ON mode (do not start
the engine, otherwise the reset mode will be canceled).
Continue to press and hold the button until the trip meter displays “000000”.
 Using the multi-information display
While the engine is running, switch the multi-information display to .
(P. 99)
Select “Maintenance System” on of the multi-information display.
Select “Yes” on the “Maintenance System” screen.
“Initialization Completed” will be displayed on the multi-information display
when the reset procedure has been completed.
■Allow inspection and repairs to be performed

The OD needs to be on Trip A.

Set OD to Trip A. Then turn vehicle off. While holding down the OD button, turn vehicle to the On position. Keep holding down OD button til reset is complete. Takes less then 10 seconds.

Thank you all for the smart insights. I didn't think to look in the manual because I assumed it required a mechanic's repair book (like a Haynes or similar).

I'll look in the manual and report back to all y'all about the results.

Either way, that internet website from Mossy Toyota is NOT working.

The odometer button procedure is for older model Toyotas before they had the small screen in the dashboard. This is how it worked on my 2008 FJ Cruiser or 2014 Venza.
