How to Reset the Change Engine Oil Message and
the Oil Life Indicator
The GM Oil Life System
t 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
Engine Oil message in the DIC being turned on, reset
the system.
After the oil has been changed, the Change Engine
Oil message and the oil life indicator must be reset.
To reset the message and indicator, use one of the
following procedures:
Base Audio System
Press the CLR button located to the right of the DIC
display to acknowledge the CHANGE ENGINE OIL
message. This will clear the message from the display
and reset it.
To reset the oil life indicator, use the following steps:
1. Press the up or down arrow on the INFO button
located to the right of the DIC display to access the
DIC menu.
2. Once XXX% ENGINE OIL LIFE menu item is
highlighted, press and hold the CLR button.
The percentage will return to 100, and the oil life
indicator will be reset.
3. Repeat the steps if the percentage does not
return to 100.
