See Engine Compartment Overview

for
the location of the engine air cleaner/filter.
When to Inspect the Engine Air Cleaner/
Filter
Inspect the air cleaner/filter at the scheduled
maintenance intervals and replace it at the first oil
change after each 50,000 mile (80 000 km) interval. See
Scheduled Maintenance
on page 7‑3
for more
information. If you are driving in dusty/dirty conditions,
inspect the filter at each engine oil change.
How to Inspect the Engine Air Cleaner/
Filter
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.
To inspect or replace the filter:
1. Remove the two screws on the top of the engine
air cleaner/filter cover.
2. Lift up the outboard side of the cover at an angle
while pulling toward you. This is necessary due to
the two hinges located on the inboard side of the
cover.
3. Remove the engine air cleaner/filter and any loose
debris that may be found in the air cleaner base.
4. Inspect or replace the air filter element.
