GM Air Filter Life System Resetting (Without Scan Tool)

When to Change Engine Air Filter If equipped, this feature provides an indication of when to change the engine air filter. It is based on driving conditions, which can cause when to change, and can vary greatly. It is possible an air filter change may not be indicated for up to four years. Replace the engine air filter when the REPLACE NOW message displays on the Driver Information Center (DIC). This should be done as soon as possible within the next 600 miles (1,000 km). The system must be reset after the engine air filter is changed. When a REPLACE AT NEXT OIL CHANGE message displays, this indicates that the engine air filter change is necessary at the next engine oil change.
