Cadillac 2007 - Manual (Page 412)

Engine Air Cleaner/Filter
See Engine
Compartment Overview
on page 406 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 (83 000 km) interval. See
Scheduled Maintenance on page 523 for more
information. If you are driving in dusty/dirty
conditions, inspect the filter at each engine oil
change.
