ENGINE OIL LIFE SYSTEM
WHEN TO CHANGE ENGINE OIL
Your vehicle has a computer system that lets you know when to change the engine oil and filter. This is based on engine revolutions and engine
temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably. For the oil
life system to work properly, you must reset the system every time the oil is changed.
When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A "CHANGE ENGINE OIL SOON"
message in the DIC will come on. Change the oil as soon as possible within the next 600 miles (1 000 km). It is possible that, if you are driving under
the best conditions, the oil life system might 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. It is also important to check the oil regularly and keep it at the proper level.
If the system is ever reset accidentally, you must change the oil at 3,000 miles (5 000 km) since your last oil change. Remember to reset the oil life
system whenever the oil is changed.
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 in the DIC being turned on, reset the system.
After the oil has been changed, the "CHANGE ENGINE OIL SOON" message must be reset. To reset the message:
1. Press the up or down arrow to scroll the DIC to show "OIL LIFE".
2. Once the XXX% ENGINE OIL LIFE menu item is highlighted, press and hold the "RESET" button until the percentage shows "100%".
If the percentage does not return to 100% or 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.
WHAT TO DO WITH USED OIL
Used engine oil contains certain elements that can 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 used oil, ask your dealer/retailer, a service station, or a local recycling center for help.
