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.
Engine Air Cleaner/Filter
See Engine Compartment
Overview on page 5-12
for the location of the
engine air cleaner/filter
and the air filter restriction
indicator, if the vehicle
has one.
When to Inspect the Engine
Air Cleaner/Filter
If your vehicle has an air filter restriction indicator,
it lets you know when the engine air cleaner/filter
needs to be replaced. On vehicles with a restriction
indicator, you should inspect the air filter restriction
indicator at every oil change and replace the engine
air cleaner/filter when the indicator tells you to.
On vehicles without an air filter restriction indicator,
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.
