How to Reset the Oil Life on a 2015 Jeep Grand Cherokee
The 2015 Jeep Grand Cherokee uses an Electronic Vehicle Information Center (EVIC) to monitor oil life and alert you when it's time for a change. Once you've completed an oil change, that indicator doesn't reset itself — you have to do it manually. Here's how the system works, how to reset it, and what to know before you do.
What the Oil Life System Actually Does
The oil life monitor in the 2015 Grand Cherokee isn't a sensor that physically tests your oil. It's an algorithm-based system that tracks driving conditions — things like engine starts, mileage, temperature cycles, and load — and uses that data to estimate how much useful life remains in your oil.
When the oil life drops to around 5%, the system displays a "Change Oil" message. At 0%, it shows "Oil Change Required." Neither warning means your engine is about to fail — it's a maintenance prompt, not an emergency alarm.
Once the oil has been changed, resetting the monitor tells the system to start tracking from 100% again. Skipping the reset doesn't hurt the engine, but it does mean you'll be looking at a meaningless warning light and won't have an accurate read on when your next change is actually due.
Step-by-Step: How to Reset the Oil Life Indicator
There are two common methods for the 2015 Grand Cherokee, depending on which steering wheel controls your vehicle has.
Method 1: Using the Steering Wheel Controls and EVIC Display
- Turn the ignition to the ON/RUN position — engine off, but electronics on.
- Use the right steering wheel control (the up/down arrow button) to scroll through the EVIC menu until you reach "Oil Life."
- Once "Oil Life" is displayed, press and hold the OK button (the checkmark or center button) for about 3 seconds.
- A prompt will appear asking you to confirm the reset. Press OK again to confirm.
- The display should return to 100% oil life.
Method 2: Using the Accelerator Pedal (No-Key Trick)
Some owners find this method faster if the steering wheel button approach doesn't seem to work:
- Do not start the engine. Turn the key to the ON position (or press the Start button twice without pressing the brake on push-button-start models).
- Fully press the gas pedal slowly three times within 10 seconds.
- Turn the ignition off, then start the engine normally and check if the oil life has reset.
This pedal method is a holdover from older Chrysler/Jeep platforms and may work as a backup if the EVIC method doesn't respond.
Key Variables That Affect This Process
Even on the same model year, a few things can change how the reset works:
| Variable | Why It Matters |
|---|---|
| Trim level | Higher trims (Limited, Summit, Overland) may have different EVIC displays or UConnect screen layouts |
| Engine type | The 2015 Grand Cherokee came with the 3.6L Pentastar V6, 5.7L HEMI V8, and 3.0L EcoDiesel — all use the same EVIC reset procedure, but the diesel has additional service reminders |
| Push-button vs. key ignition | Affects how you enter ON/RUN mode without starting the engine |
| Previous software updates | Dealer software updates can occasionally affect EVIC menu behavior |
The Oil Change Interval Question
Resetting the monitor is straightforward. What's less straightforward is knowing how often to change the oil in the first place.
The EVIC system will calculate an interval based on your actual driving patterns. But that calculation works alongside — not instead of — the manufacturer's service guidance in your owner's manual. 🛠️
Factors that affect how quickly oil degrades in any vehicle include:
- Short trips (under 10 miles), which don't allow the engine to fully warm up
- Towing or hauling, which increases engine stress
- Extreme temperatures, hot or cold
- Oil type used — conventional, synthetic blend, or full synthetic behave differently
The 2015 Grand Cherokee with the 3.6L V6 and 5.7L HEMI typically specifies SAE 5W-20 oil. The 3.0L EcoDiesel has different oil type and interval requirements. Using the wrong oil type can affect how accurately the EVIC algorithm tracks degradation — and using the right one matters for engine longevity regardless.
When the Reset Won't Hold
If the oil life indicator resets but comes back almost immediately, or won't reset at all, a few things could be going on:
- The reset wasn't confirmed properly (missed the second OK press)
- There's an underlying fault code being read as an oil system issue
- A battery disconnect scrambled EVIC memory (though this usually sets oil life back to 100% on its own)
An OBD-II scanner can confirm whether there are any stored fault codes that might be interfering. This is worth checking before assuming the EVIC system itself has a problem.
What's Left Is Specific to Your Situation
The reset steps above apply broadly to the 2015 Jeep Grand Cherokee, but the exact EVIC layout you see, the oil specification your engine requires, and how the system behaves after a reset all depend on your specific engine, trim, and service history. Your owner's manual — section by section — remains the most accurate reference for your exact vehicle as it came from the factory.
