Engine Air Cleaner/Filter; When To Inspect - Cadillac ESCALADE EXT 2004 Owner's Manual

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.

Engine Air Cleaner/Filter

When to Inspect

If your vehicle is equipped with 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,
you should inspect the air cleaner/filter at every oil
change and replace it at the first oil change after
25,000 miles (40 000 km). See Scheduled Maintenance
on page 6-4 for more information.
See Engine Compartment
Overview on page 5-10 for
location of engine air
cleaner/filter and air filter
restriction indicator (if
equipped).
