2007 Chevrolet Cobalt Reset the Oil Life
The Chevrolet Cobalt is a small car powered by a transverse-mounted, four-cylinder engine. The oil-life indicator in the Cobalt flashes a warning on the dashboard display to let you know an oil change is due. The oil-life system uses such variables as engine speed and temperature to determine when the oil needs changing. If you drive the car mostly in the city, on hilly terrain or in a hot climate, it will need an oil change sooner than if you drive mostly on freeways or in moderate temperatures. In order for the oil-life system to function properly, you must reset it after each oil change.

 Reset the Oil Life
- Sit in the driver's seat and turn the ignition key to the "RUN" position. Do not start the motor.
- Press and release the "Information" and the "Reset" buttons simultaneously to enter the personalization menu. The buttons are located on the driver information center (DIC) on the dashboard.
- Press the "Information" button repeatedly until the message "OIL-LIFE RESET" shows up on the DIC screen.
- Press the reset button and hold it in until the message "ACKNOWLEDGED" appears in the DIC screen.
- Turn the ignition key to the "LOCK" position and remove it.
 Tips & Warnings
- The oil-life system in the Cobalt does not use mileage as one of its criteria for determining the next oil change, but if you forget to reset your oil-life system, change the oil 3,000 miles after the previous oil change.
- If you still get the message "CHANGE OIL SOON" after resetting the oil-life system, the reset did not take. Repeat the procedure for resetting the oil-life system again.
- When the message "CHANGE OIL SOON" appears in the DIC display, change your engine oil within 600 miles.
- It is possible for the "CHANGE OIL SOON" message to not appear on the DIC for over one year if the car is driven only occasionally. In this case, change the engine oil annually regardless of the DIC message. Engine oil breaks down over time and your engine could be permanently damaged by driving with old oil.
