How do you reset the engine oil life? I had the oil changed at the dealership today and they forgot to do it.

Did you have the oil changed lately ?
Oil Life Left
Oil life left percentage is based on the information the DIC receives from a class 2 message from the PCM. The DIC displays the current percentage of the GM Oil Life System. When the oil needs changing the change engine oil indicator in the message center turns ON. When the engine oil is changed, reset the oil life left. Refer to GM Oil Life System Resetting in Maintenance and Lubrication.

GM Oil Life System Resetting
When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE ENGINE OIL message will come on. Change the engine oil as soon as possible within the next 600 miles (1 000 km). It is possible that, if driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, the engine oil and filter must be changed at least once a year and at this time the system must be reset.
If the system is ever reset accidentally, change the engine oil at 3,000 miles (5 000 km) since last oil change.
How to Reset the Engine Oil Life System
If the vehicle does not have optional Driver Information Center (DIC) , do the following:
Turn the ignition to ON, with the engine off.
Fully press and release the accelerator pedal slowly three times within five seconds.
Turn the key to OFF. If the CHANGE ENGINE OIL message comes back on when you start the vehicle, the Engine Oil Life System has not reset. Repeat the procedure.
If the vehicle has the optional DIC, do the following:
Turn the ignition to ON, with the engine off.
Press the MODE button until the DIC reads OIL LIFE LEFT/HOLD SET TO RESET.
Press and hold the SET button until 100 percent is displayed. You will hear three chimes and the CHANGE ENGINE OIL message will go off.
Turn the key to OFF.
If the CHANGE ENGINE OIL message comes back on when you start the vehicle the Engine Oil Life System has not reset. Repeat the procedure.

This procedure work for one 2004... press mode button until oil life or change oil or change oil now is displayed press and hold mode button for 5 seconds until reset for new oil is displayed then hold reset for 2 seconds.

Additionally, I quite other comments about this subject....

Few issues have troubled technicians more than the infamous "Change oil soon light." We have even had quick lube shops send customers to me at the dealership to shut off this light.
Yes, the engineer that designed this system most certainly had flunked out of the "User Friendly" semester of college. The most common problem is between step 1 and 2 of the owner's manual. The natural tendency is that when we scroll through the menu to the "oil life XX%" mode, we lift our finger. This is where most go wrong. Once the "oil life XX%" comes up on the menu, do NOT lift from depressing the button- just hold for 5 seconds until the "Reset for new oil life" comes up. Again, do not lift your finger.

The parking assist is a different concern altogether. The parking assist light illuminated when it is deactivated- opposite of what seems logical. It was probably the same design engineer as the oil change system. If the system is disabled, (illuminated) it is intended to cycle back when the key is shut off.

Hope helps.

Courtesy of oilreset.com:
Turn the ignition to (II) - do not start the engine. Press the SEL/RESET button on the steering wheel repeatedly until engine oil life is displayed. Press and hold the SEL/RESET button for more than 10 seconds. The remaining engine oil life reset mode will be shown on the multi information display. Select RESET by pressing the INFO (??²/??¼) button, then press the SEL/RESET button to reset the engine oil life display. The maintenance item code(s) will disappear, and the engine oil life will reset to 100. Turn the ignition off and then start the engine to verify the indicator has been reset. *Models equipped with the keyless access system have an engine start/stop button instead of an ignition switch. Pushing start/stop button once without starting engine is equivalent of ignition (II).
Best of luck! Greg

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 the oil is changed prior to a CHANGE ENGINE OIL SOON message being turned on, reset the system.
Always reset the engine oil life to 100% after every oil change. It will not reset itself. To reset the Engine Oil Life System:
Display the OIL LIFE REMAINING on the DIC.
Press and hold the SET/RESET button on the DIC for more than five seconds. The oil life will change to 100%.
If the CHANGE ENGINE OIL SOON message comes back on when the vehicle is started, the Engine Oil Life System has not reset. Repeat the procedure.
Good luck and thanks for your question and I hope my suggestions help. burdfrenzy

there is no light for emissions testing on this vehicle. there is a ses light that can come on, indicationg a problem with the engine or transmission electronic system. this will require a scan tool to pull trouble codes. there is another light called oil life monitoring that needs to be reset after oil changes, which I suspect is what you are seeing. here is a picture of the light and the instructions for resetting.,

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, the system must be reset as follows:

1. Turn the ignition to RUN, with the engine OFF.
2. Press the information and reset buttons on the Driver Information Center (DIC) at the same time to enter the personalization menu.
3. Press the information button to scroll through the available personalization menu modes until the DIC display shows OIL LIFE RESET.
4. Press and hold the reset button until the DIC display shows ACKNOWLEDGED. This will tell you the system has been reset.
5. Turn the key to LOCK.

If the CHANGE ENGINE OIL message comes back on when you start the vehicle, the Engine Oil Life System has not reset. Repeat the reset procedure.

Most often you need a code reader with a reset function that can connect to the computer jack under the dash and reset factory functions like that. Pain in the tush if you are changing your own oil. Mechanics and dealers have the equipment to do that reset.

Guess the guys at the dealership forgot to reset your oil chage light. Check your oil to make sure its not black. If its at a good brownish color then get to your oil life screen on your car and i belive you hold down the check mark button till the oil light resets (30sec) or so.

there is a reset button- or do something in your car to trigger the reset. for example on most gm models to reset the oil light you turn the ignition on, but not the engine then hit the gas pedal 6 times (6 times under 10 seconds) and it resets it. You can try this but not sure it will work on fords, if it does not just call and ask your local dealership. god bless.

THIS SHOULD BE IT.
How do I reset the Engine Oil life monitor and how does it work? TO reset To reset the Engine Oil Life monitor do the following:
Reset Oil life in NAV/DIC by (with car running) going to INFO>Oil Life>RESET
Press and HOLD until XXX turns to 100%
How does it work? The oil life monitor is a pretty sophisticated algorithm.

GM "The GM Oil Life System will automatically adjust the oil change interval based on engine characteristics, driving habits and the climate in which the vehicle is operated."

you most likely need to take the cat to a saturn dealership to have the code reset for the oil change light. Saturn is notorious for designing their cars so that it is necessary to the dealership for repairs.
