GM Chevrolet Avalanche - Manual (Page 356)

Engine Air Cleaner/Filter
See Engine Compartment
Overview on page 5-14 for
the location of the
engine air cleaner/filter and
the air filter restriction
indicator, if equipped.
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,
inspect the air cleaner/filter at the Maintenance
II
intervals and replace it at the first oil change after
50,000 miles (83 000 km). 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.
