Method 1 (Most Common):
1. Turn the ignition key to the "ON" position (but don't start the engine). The instrument cluster should illuminate.
2. Locate the odometer display.
3. Find the button or sequence to access the trip odometer or information menu. This is usually a button on the steering wheel or a stalk near the turn signal stalk. The exact location and method vary – consult your owner's manual for specifics. You might need to cycle through various menus to find the option to reset the oil life.
4. Look for a "maintenance" or "oil life" indicator. Once found, follow the instructions in your manual for resetting it. It often involves holding down a button for several seconds, or a specific button combination.
Method 2 (Less Common, may require a scan tool):
Some Aztecs may require a scan tool to reset the oil life monitor. This is a specialized tool that plugs into the car's diagnostic port (usually under the dashboard). Many auto parts stores will perform this service for free.
Crucial Note: Your owner's manual is the definitive source. The procedures above are general guidelines. Your Aztec's owner's manual will have the precise steps for resetting the oil change indicator for your specific model. Check the manual first to avoid any potential issues.
If you can't find the information in the manual or the above methods don't work, a visit to a mechanic or auto parts store is recommended. They have the tools and knowledge to reset the light properly. Don't ignore the oil change light, as it indicates the need for an oil change to protect your engine.
