If your vehicle has the Engine Oil Life System, it has a computer system that lets you know when to change the engine oil and filter. This is based on injection timing, engine load 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 light will come on. See Change Engine Oil Light . Change your oil as soon as possible within the next 600 miles (1 000 km) or 30 hours of engine operation, whichever occurs first. It is possible that, if you are driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, your engine oil and filter must be changed at least once a year and at this time the system must be reset. Your dealer has trained service people who will perform this work and reset the system. It is also important to check your oil regularly and keep it at the proper level.

If the system is ever reset accidentally, you must change your oil at 3,000 miles (5 000 km), or 150 hours of engine operation, whichever occurs first, since your last oil change. Remember to reset the oil life system whenever the oil is changed.

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 engine oil light being turned on, reset the system.

To reset the Engine Oil Life System, do the following:

1. Turn the ignition key to ON with the engine off.
2. Fully press and release the accelerator pedal slowly three times within 10 seconds.

If the change engine oil light flashes for five seconds, the system is resetting.

3. Turn the key to LOCK.

If the change engine oil light comes back on when you start your vehicle, the Engine Oil Life System has not reset. Repeat the procedure.

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.
