The Jeep Grand Cherokee is a rugged and reliable SUV, but like any vehicle, it requires regular maintenance to keep running smoothly. One essential part of that maintenance is changing the engine oil. Your Jeep Grand Cherokee’s onboard computer keeps track of the oil life and will remind you when it’s time for an oil change. But sometimes, you might need to reset the oil life monitor after changing the oil yourself or after a dealer service. This blog post will guide you through the process of resetting the oil life in your Jeep Grand Cherokee.
Understanding the Oil Life Monitor
The oil life monitor in your Jeep Grand Cherokee uses a complex algorithm to determine when it’s time for an oil change. It considers factors like driving conditions, engine load, and oil temperature. When the oil life monitor reaches 0%, it’s time to change the oil.
Why Reset the Oil Life Monitor?
Resetting the oil life monitor is essential after changing the oil. The monitor doesn’t automatically reset itself, and continuing to drive with a 0% oil life reading can lead to inaccurate maintenance reminders and potentially damage your engine.
Resetting the Oil Life Monitor: A Step-by-Step Guide
Step 1: Start the Engine
Turn the ignition key to the “ON” position, but don’t start the engine.
Step 2: Access the Information Center
Locate the button on your steering wheel or dashboard that controls the information center display. This button is usually labeled “INFO” or “TRIP.”
Step 3: Navigate to the Oil Life Setting
Press the “INFO” or “TRIP” button repeatedly until you reach the oil life display. This display will show the percentage of oil life remaining.
Step 4: Reset the Oil Life
Now, you need to follow these steps depending on your Jeep Grand Cherokee model year:
For models with a single “OK” button:
- Press and hold the “OK” button for about 5 seconds.
- You should see a message confirming the reset.
- Release the “OK” button.
For models with multiple buttons:
- Press and hold the “UP” and “DOWN” buttons simultaneously for about 5 seconds.
- You should see a message confirming the reset.
- Release the buttons.
Step 5: Confirm the Reset
Once the oil life monitor is reset, the display should show 100% oil life.
Additional Tips for Resetting the Oil Life Monitor
