Chevrolet Cobalt 2005-2010 Oil Life Reset Guide
The Cobalt fell short of the best small cars. Its 2.2-liter engine was noisy and relatively thirsty. The ride was relatively comfortable, but handling wasn’t agile. The steering was too light at low speeds. The rear seat was not roomy, even by small-car standards, and interior fit and finish was unimpressive. The turbocharged SS version was quick and fun to drive. The Cobalt sedan received a score of acceptable in the IIHS side-crash test with the standard head-curtain air bags. ESC was only available on higher-trim models.
How to Reset the Engine Oil Life System
The Engine Oil Life System calculates when to change your engine oil and filter based on vehicle use. Whenever the oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where the oil is changed prior to a CHANGE OIL SOON message being turned on, reset the system.
After changing the engine oil, the system must be reset:
1. Turn the ignition to RUN, with the engine off.
2. Press the information and reset buttons on the DIC at the same time to enter the personalization menu.
3. Press the information button to scroll through the available personalization menu modes until the DIC display shows OIL-LIFE RESET.
4. Press and hold the reset button until the DIC display shows ACKNOWLEDGED. This will tell you the system has been reset.
5. Turn the key to LOCK.
If the CHANGE OIL SOON message comes back on when you start your vehicle, the engine oil life system has not reset. Repeat the reset procedure.
