How do I reset the oil life monitor?

If it's the Oil Life Monitor, all you need to do is turn the key ON (do not start the car) and press the gas pedal down three times within 5 seconds. You will get a confirmation chime and the oil life monitor light will flash and turn off. If it doesn't work, try it again.

The instructions for turning the oil life monitor light off are in the owner's manual. If you don't have a manual, go to www.mygmlink.com and sign up for an account... You will be able to access the owner's manual online for free. http://www.mygmlink.com/

GM OIL LIFE SYSTEM - RESETTING
The engine oil life monitor will indicate when to change the engine oil - usually between 5 000 km (3,000 miles) and 16 000 km (10,000 miles) since the last oil change. Under severe conditions, the "CHANGE OIL SOON" light may be displayed before 5 000 km (3,000 miles). The vehicle must not be driven more than 16 000 km (10,000 miles) or 12 months without an oil change.

Reset the oil life monitor when the oil has been changed, use the following procedure:

1. Turn the ignition key to the RUN position.
2. Fully push and release the accelerator pedal 3 times within 5 seconds.
3. If the Change Oil Soon light flashes, the system is resetting.
4. Start the vehicle.
5. The oil life will change to 100%.
6. If the Change Oil Soon light comes back on, the system has not reset. Repeat the procedure.

If the oil light is on, you need to stop operating the engine and have it checked to find out why the light is telling you that there is no oil pressure.

Depending on your model your owners manual should have instructions that guide you through the process. To reset the oil monitor in my jeep the dash has a menu button you scroll through until you get to the oil life then you press step until you scroll through the options you need like 3000, 4000, 5000 miles. it will ask if you want it reset and you press yes. Its very simple.

Press reset until OIL LIFE is displayed. Hold in button for 10 seconds. Select oil life and hold in button until it resets. It should be same in your owners manual. You can always ask what the step is, but they may be annoyed that you are not using them for oil changes. If you have them perform the oil change, then its included. Its better for you because they will be using quality Honda Oil filters and oil.

There are instructions in the owners manual. These are for when you get the final "Oil Chanmge Required" message:
To reset the oil monitoring system to 100% after each oil change
(approximately 7,500 miles [12,000 km] or six months) perform the
following:
1. Press and hold the RESET
control for two seconds and release.
Oil life is set to 100% and “OIL LIFE
XXX% HOLD RESET IF NEW OIL”
is displayed.
2. Press and hold the RESET
control for three seconds and
release. Oil life is set to 100% and
“OIL LIFE START VALUE SET TO
XXX%” is displayed.

This procedure is on pages 69-70 of your owners manual, this is copied and pasted from that manual

Hello. What that means is that only 16% of your car's oil life remains before you should get an oil change. This is a better method of knowing when to change the oil than the old fashioned rule of thumb of merely changing the oil every 3,000 miles.
When you do have the oil changes, the counter can be reset back to 100%. If you have your oil changed at a garage, they will reset the counter for you. otherwise look in the owner manual for the instructions on how to reset the counter. regards, Joe
