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 and filter, the system
must be reset. To reset the oil life system, use
the following procedure:
1. With the CHANGE OIL SOON message
displayed, press any of the three DIC
buttons to clear the CHANGE OIL SOON
message. See DIC Warnings and Messages
on page 212.
2. Display OIL LIFE RESET on the DIC.
3. Press and hold the ENTER button for at least
one second. An ACKNOWLEDGED display
message will appear for three seconds or until
the next button is pressed. This will tell you
the system has been reset. See DIC Vehicle
Personalization on page 216.
4. Turn the ignition to OFF.
If the CHANGE OIL SOON message comes back
on when you start your vehicle, the engine oil
life system has not reset. Repeat the procedure.
