ENGINE 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" message being turned
on, reset the system.
To reset the Engine Oil Life system, do the following:
1. With the engine off, turn the ignition to "ON".
2. Press and release the stem in the lower center of the instrument cluster until the "OIL LIFE" message is displayed.
3. Once the alternating "OIL LIFE" and "RESET" messages appear, press and hold the stem until several beeps sound. This confirms that the oil life
system has been reset.
4. Turn the key to "LOCK".
If the "CHANGE OIL" 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 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.
