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.
See DIC Warnings and Messages on page 196.
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.
