Engine Oil Life System

The engine oil life system calculates
engine oil life based on vehicle use
and displays the CHANGE ENGINE

change the engine oil and filter. The
oil life system should be reset to 100%
only following an oil change.
Resetting the Oil Life System
1. Using the DIC controls on the
right side of the steering wheel,
display REMAINING OIL LIFE on
the DIC. See Driver Information
Center (DIC) 0 128. When
remaining oil life is low, the
CHANGE ENGINE OIL SOON
message will appear on the
display. See Engine Oil
Messages 0 137.
2. Press and hold SEL to clear the
CHANGE ENGINE OIL SOON
message and reset the oil life
at 100%.
Be careful not to reset the oil life
display accidentally at any time
other than after the oil is
changed. It cannot be reset
accurately until the next oil
change.
The oil life system can also be reset as
follows:
1. Turn the ignition on with the
engine off.
2. Fully press and release the
accelerator pedal three times
within five seconds.
If the CHANGE ENGINE OIL
