(1) Or every two years, whichever comes first. More frequent replacement may be needed if the vehicle is driven in areas with heavy traffic, poor air quality, areas with high dust levels or are sensitive to environmental allergens. Filter replacement may also be needed if you notice reduced airflow, windows fogging up, or odors. Your local GM Service location can help you determine when it is the right time to replace your filter.

(2) 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.

(3) Visually check all fuel and vapor lines and hoses for proper attachment, connection, routing, and condition.

(4) Do not directly power wash the transfer case and/or front/rear axle output seals. High pressure water can overcome the seals and contaminate the fluid. Contaminated fluid will decrease the life of the transfer case and/or drive axles and should be replaced.

(5) Or every five years, whichever comes first. See Cooling System.

(6) Or every 10 years, whichever comes first. Inspect for fraying, excessive cracking, or damage; replace, if needed.

(8) Or every 12 months, whichever comes first. See Wiper Blade Replacement.
