Reset that maintenance light "ON"

If you do your own oil changes on your '06 Toyota Corolla you will notice the maintenance light "ON". To reset it and turn the light off you would have to hold down the odometer pin down while you turn your ignition key to the "ON" position and hold that for 5-8 seconds. Do not crank and start the car.
You will see dashes on the odometer disappear. Now the maintenance light has reset till the next oil change.
The '06 Toyota 4Runner is the same procedure but you will not see dashes like the Corolla. You will see the Maint light will flash for 5-8 seconds until it is gone.
