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 the oil is changed prior to a CHANGE ENGINE OIL
SOON message in the Driver Information Center (DIC)
being turned on, reset the system.
After the oil has been changed, the CHANGE ENGINE
OIL SOON message must be reset:
1. Turn the key to the ON/RUN position without
starting the engine.
2. Press the INFO button on the Driver Information
Center (DIC) until OIL LIFE REMAINING is
displayed. See DIC Operation and Displays on
page 3-68.
3. Press and hold the INFO RESET button until 100%
is displayed. This resets the oil life indicator.
4. Turn the key to LOCK/OFF.
If the CHANGE ENGINE OIL SOON message comes
back on when the vehicle is started, 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. Recycle it by taking it to a
place that collects used oil.
Engine Air Cleaner/Filter
See Engine Compartment Overview on page 5-12 for
the location of the engine air cleaner/filter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at the Maintenance II
intervals and replace it at the first oil change after each
50,000 mile (80 000 km) interval. See Scheduled
Maintenance on page 6-4 for more information. If you
are driving in dusty/dirty conditions, inspect the filter
at each engine oil change.
