(1) Or every four years, whichever comes
first. If driving in dusty conditions, inspect
the filter at each oil change or more often
as needed. See Engine Air Cleaner/Filter
0 243.
(2) 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.
(3) Visually check all fuel and vapor lines
and hoses for proper attachment,
connection, routing, and condition.

canister filter replacement interval, replace
the fluid and filter. More frequent fluid and
filter replacement may be needed if the
vehicle is competitively or aggressively
driven. This service can be complex. See
your dealer. (5)
Check the transmission fluid
life percentage. If the percentage is less
than 10%, replace the fluid and filter. The
initial transmission canister filter change

and every 36 000 km (22,500 mi) thereafter.
This service can be complex. See your
dealer.

Additional Maintenance
and Care
Your vehicle is an important investment and
caring for it properly may help to avoid
future costly repairs. To maintain vehicle
performance, additional maintenance
services may be required.
It is recommended that your dealer perform
these services —their trained dealer
technicians know your vehicle best. Your
dealer can also perform a thorough
assessment with a multi-point inspection to
recommend when your vehicle may need
attention.
The following list is intended to explain the
services and conditions to look for that may
indicate services are required.
