How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to
change the engine oil and filter based on vehicle
use. Whenever the oil is changed, reset the
system so it can calculate when the next oil
change is required. If a situation occurs where
you change the oil prior to a CHANGE ENGINE
OIL SOON message being turned on, reset
the system.
If your vehicle does not have a Driver Information
Center (DIC):
1. Turn the ignition to ON, with the engine off.
2. Fully press and release the accelerator pedal
slowly three times within five seconds.
3. Turn the key to OFF.
If the CHANGE ENGINE OIL SOON message
comes back on when you start your vehicle,
the engine oil life system has not reset.
Repeat the procedure.
If your vehicle has a DIC:
1. Turn the ignition to ON, with the engine off.
2. Press the MODE button until the DIC
reads OIL LIFE LEFT/HOLD SET TO RESET.
3. Press and hold the SET button until 100% is
displayed.
You will hear three chimes and the CHANGE
ENGINE OIL SOON message will go off.
4. Turn the key to OFF.
If the CHANGE ENGINE OIL SOON message
comes back on when you start your vehicle,
the engine oil life system has not reset.
Repeat the procedure.
