There are three major warning light issues:

For the oil change/oil filter warning: Start with the ignition switch "ON" 1. Push the "ODO/TRIP" button to change the display to blank. 2. Turn the ignition switch off. 3. Turn the ignition switch to "ON" with the trip meter "RESET" button held down. 4. Keep pushing the "RESET" button for longer than 5 seconds after the ignition is turned on. 5. the master warning light comes on, a warning tone sounds and the message disappears.

You can disconnect your battery for 15 minutes or pull the fuse for an ECM or PCM fuse, but the best way is to visit any local repair shop. Most shops will have a universal Check Engine Light Code Reader that can quickly and safely reset check engine light trouble codes. It should take about 30 seconds.

Ask your local service center if they could reset the check engine light with a Check Engine Light Code Reader.

Main reop light in dash

Hello, and welcome to FixYa.

The 'Maint Reqd' light indicates that you are due for an oil change. It will blink 4,500 miles since the light was reset at your last oil change, and stay on steady after 5,000 miles.

If you recently had an oil change, all you need to do is reset your maintenance reqd lamp. The procedure is here on this site inthe 'tips and tricks' section, and it is also in your owner's manual.

TOYOTA SIENNA MAINT REQD LITE CAME ON AFTER SCHEDULE MAINTANANCE

If the dealer/mechanic did the service early the light will come on when service is DUE. Go back to him and have it turned off. Search the web someone may have the procedure posted. Usually simple. Google "Toyota service light reset" or "Toyota Maintence light reset" Try this one
  1. With the car started (ignition on), set the LCD odometer readout to total mileage (not trip A or B).
  2. Turn the car off (ignition key to the OFF position).
  3. Push in AND HOLD the button/knob that switches the odometer
  4. Turn key to ON position without starting the car. You will notice the maintenance light blink and go out.
  5. Release the odometer button/knob.
  6. Turn key to OFF position.
  7. That's it! The "MAINT REQD" light has been reset to warn you to change your oil in another 5,000 or 7,500 miles or so.

1. Push the “ODO/TRIP” button to change the display to
blank.
2. Turn the ignition off.
3. Turn the ignition switch to “ON” with the trip meter
“RESET” button held down.
4. Keep pushing the “RESET” button for longer than 5

"maint reqd".

That is for oil changes. It come on when the oil change is due.
When you have your oil change done, the lube tech should reset the this light every time.
If you need help resetting the light, let me know.
