Oil Light

Turn the car's systems on, but leave the engine off. Typically, this requires turning the key part-way in the ignition, without turning it enough to start the engine.

Locate the "Reset" button or stick, which is typically located on the dashboard, near the speedometer and fuel gauge. If you don't see a "Reset" button on the dashboard, it's probably under the hood. If necessary, consult your manual, or contact the manufacturer's customer service department.

Hold the button down until the "Oil" icon or word starts to flash, or the indicator lights show some other sign of resetting. Some cars will flash the word "Reset," or display the numeral "100" to show that 100 percent of oil life remains after the oil change.

Turn the ignition off, wait a few moments, and then start the engine. Look at the dash to see if the oil light is still flashing or lit. If so, repeat the reset process. If the light is still lit after three reset attempts, contact the manufacturer to learn the correct reset procedure for your vehicle. If you can't reach the manufacturer, you can call a local mechanic, who will probably be willing to tell you how to reset the oil light, provided you know the car's make, model and year.
