From the Manual:
How to Reset the Engine Oil Life System
The Engine Oil Life System calculates when to change your engine oil and filter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a CHANGE OIL SOON message being turned on, reset the system.
After changing the engine oil, the system must be reset as follows:
1. Turn the ignition to RUN, with the engine off.
2. Press the information and reset buttons on the DIC
at the same time to enter the personalization menu.
See DIC Vehicle Personalization on page 3-45.
3. Press the information button to scroll through the
available personalization menu modes until the
DIC display shows OIL-LIFE RESET.
4. Press and hold the reset button until the DIC display
shows ACKNOWLEDGED. This will tell you the
system has been reset.
