Inspect the air cleaner/filter at the Maintenance II
intervals and replace it at the first oil change

Scheduled Maintenance on page 391 for more

conditions, inspect the filter at each engine oil

How to Inspect the Engine Air
Cleaner/Filter
2.2L and 2.4L L4 Engines
To inspect the air cleaner/filter remove the filter
from the vehicle and lightly shake the filter to
release loose dust and dirt. If the filter remains
caked with dirt, a new filter is required. Never use
compressed air to clean the filter.
To inspect or replace the filter, remove the screws
that hold the cover on and lift off the cover. Be
sure to reinstall the cover tightly.
2.0L L4 Supercharged Engine
There is a special procedure for inspecting and
replacing the filter. Because this procedure
is difficult, you should have it done at your dealer
service department. Contact your dealer for
additional information, or the procedure can be
found in the service manual. To purchase a service
manual, see
