RE: the Tacoma maint required light.
That’s your time-to-change-the-oil indicator. It starts blinking about 4,500 miles after the last reset; at 5,000 miles, it stays on solid. You can’t set it to where it won’t come on, but you can reset it yourself:
The Tacoma has the regular odometer readout, and it has 2 trip odometers (A & B). The reset procedure is to (with the truck off and the key out) select the “Trip A” odometer, then push and hold it while you insert the key and turn it to “ON” (not “Start”, “ON” - where the dash lights all come on). Keep holding it for at least 5 seconds - the light should reset and stay off until you go another 4500 miles.
I now drive a 2015 Taco and it is by far the most complex peice of machinery I have ever operated.
There is a secret filter meant to prevent reverse release of gas fumes when the vehicle is turned off.
My goal in life is to find that filter and remove it; word on the street is that I can realize an increase of 2 to 4 HP.
The filter serves no other purpose.
