Method 1: Simple Indicator Light (Least Common)
Some simpler models might only have a basic oil change light. In this case, the reset is often just a matter of:
1. Turning the ignition to the "ON" position (but not starting the engine).
2. Repeatedly pressing the gas pedal to the floor. The exact number of times can vary; try 3-5 times. Some say you need to hold it down for a few seconds.
3. Turning the ignition off.
4. Check if the light is off.
This method is less likely with a 2007 model, but it's worth a quick try before moving on.
Method 2: DIC Reset (Most Likely)
This is the more probable method for your 2007 Express. Your van likely has a Driver Information Center (DIC) which displays various information, including the oil life percentage. You'll need to navigate the DIC menu. The precise steps vary slightly depending on the specific DIC configuration. However, the general approach is:
1. Turn the ignition to the "ON" position (but don't start the engine).
2. Locate the "SETTINGS" or "MENU" button on your steering wheel or instrument cluster. This button will usually cycle through various DIC options.
3. Use the button to navigate the menu until you find an option related to "OIL LIFE," "MAINTENANCE," or "OIL CHANGE." The exact wording may differ.
4. Once you find the correct option, you'll likely see a prompt to reset the oil life. You may need to press the button again to confirm the reset. You might need to use the up/down arrows on the steering wheel to select "Reset" or similar.
5. Turn the ignition off. The oil change indicator should now be reset.
Method 3: OBDII Scanner (If other methods fail)
If neither of the above methods work, you can try resetting the oil life reminder using an OBDII scanner. Many inexpensive scanners are available online or at auto parts stores. These scanners connect to your vehicle's diagnostic port (usually under the dashboard) and allow you to access and reset various vehicle parameters, including the oil life reminder. Follow the instructions that came with your specific OBDII scanner. Note that this method requires some mechanical knowledge.
Important Note: Remember to actually *change your oil* at the recommended intervals (check your owner's manual) regardless of what the indicator light says. The light is just a reminder, not a substitute for proper maintenance. If you're unsure about any of these steps, consult your owner's manual or a qualified mechanic.
