GM OIL LIFE SYSTEM
HOW TO RESET THE ENGINE OIL LIFE SYSTEM
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" light being
turned on, reset the system.
After changing the engine oil, reset the system by performing the following steps:
1. Turn the ignition key to "RUN" with the engine off.
2. Fully press and release the accelerator pedal slowly three times within five seconds. If the "CHANGE OIL SOON" light flashes, the system is
resetting.
3. Turn the key to "OFF", then start the vehicle. The oil life will change to 100 percent. If the "CHANGE OIL SOON" light comes back on when you
start your vehicle, the engine oil life system has not reset. Repeat the procedure.
WHAT TO DO WITH USED OIL
Used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for
very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine
oil. See the manufacturer's warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil
by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects
used oil. If you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help.
