How to Reset the Change Oil Light on a 2004 Oldsmobile Alero 2.4

by Justin Cupler

Oldsmobile released the Alero for the 1999 model year. The Alero gave Oldsmobile a new presence in the sporty, family car market, which it lacked at the time. The Alero only lasted six model years, as General Motors cut the entire Oldsmobile lineup in 2004. the 2004 Alero came standard with a 2.2-liter four-cylinder that produced 140 horsepower. It also had a 170-horsepower, 3.4-liter V-6 engine as an available option. The 2004 Alero was fitted with GM's "Oil Life System," which illuminated a "Change Oil" light at precise oil change intervals. Resetting this "Change Oil" light is a simple process that only takes a few minutes.

Insert the ignition key into the Alero's ignition and turn it to the "On" position, but do not start the vehicle.

Press and release the accelerator pedal three times within five seconds.

Listen for an audible chime and watch for the "Change Oil" light to extinguish indicating the resetting of the system.

Turn the ignition to the "Off" position.

Start the Alero and verify the "Change Oil" light remains off. If the light illuminates, repeat the entire procedure.


  • In the case of accidental system resetting, default to the manufacturer-recommended 3,000 mile intervals between oil changes.


  • This system does not measure oil quality, only miles elapsed. Always keep track of your Alero's mileage and change the oil at 3,000 miles intervals, regardless of the light, as the system can fail.
