(1)

Or every two years, whichever

comes first. More frequent
passenger compartment air filter
replacement may be needed if
driving in areas with heavy traffic,
poor air quality, high dust levels,
or environmental allergens.

Passenger compartment air filter
replacement may also be needed if
there is reduced airflow, window
fogging, or odors. Your GM dealer
can help determine when to replace
the filter.

(2)

Visually check all fuel and vapor

lines and hoses for proper
attachment, connection, routing, and
condition.

(3)

Or every four years, whichever

comes first. If driving in dusty
conditions, inspect the filter at each
oil change or more often as needed.
