Method 1: Using the Trip Odometer Reset Button:
1. Turn the ignition key to the "ON" position (but don't start the engine).
2. Locate the trip odometer reset button. This is usually a small button on the instrument cluster, often near the speedometer or odometer.
3. Press and hold the trip odometer reset button. Some models require you to hold it for several seconds, while others might involve a sequence of presses.
4. Cycle the ignition switch. Turn the key to the "OFF" position, then back to "ON" without starting the engine. Sometimes you may need to repeat this step several times.
5. Observe the oil life indicator. If the reset was successful, the light should extinguish or the oil life percentage should reset to 100%.
Method 2: Using the DIC (Driver Information Center) Menu (if equipped):
Not all 2004 Jeep Grand Cherokees have a fully featured DIC. If yours does, you may have a menu-driven system. The exact steps vary, but generally involve:
1. Turn the ignition key to the "ON" position (but don't start the engine).
2. Navigate to the "Settings" or "Maintenance" menu on the DIC using the steering wheel controls. This is typically done using buttons on the steering wheel.
3. Find the option to reset the oil life. The wording might vary ("Oil Life Reset," "Oil Change Indicator," etc.).
4. Select the option and confirm the reset. You may need to press a button repeatedly or follow prompts on the DIC screen.
If Neither Method Works:
* Consult your owner's manual: This is the most reliable source of information for your specific vehicle. The manual should have detailed instructions for resetting the oil change indicator.
* Check online forums: Search for "2004 Jeep Grand Cherokee oil change light reset" on Jeep forums. Other owners may have posted solutions specific to your trim level.
* Visit a mechanic: If all else fails, a mechanic can easily reset the light using a diagnostic scanner.
Important Note: Resetting the oil change indicator light doesn't actually change your oil. Always change your oil and filter at the recommended intervals (check your owner's manual), regardless of what the indicator light says. The light is just a reminder.
