Maintenance light on?
After performing an engine oil change on a 2007 Toyota Tundra, a simple procedure is required to turn off the maintenance reminder light.
1. Turn the ignition switch to the ON position and set the odometer to “TRIP A.”
2. Turn the ignition switch to the ACC or LOCK position.
3. While pushing the trip meter reset knob, turn the ignition switch to the ON position.
4. With the ignition switch in the ON position, keep holding the trip meter reset knob for at least five seconds as the LCD counting down. When the reset is complete, the display will show “000000” for one second. The maintenance light will now turn off. Release the trip meter reset knob when the reset is complete.
