Engine Oil Change
When the CHANGE ENGINE OIL SOON message displays, have the engine oil and filter changed within the next 1 000 km/600 mi. If driven under the best conditions, the engine oil life system may not indicate the need for vehicle service for up to a year. The engine oil and filter must be changed at least once a year and the oil life system must be reset. Your trained dealer technician can perform this work.
If the engine oil life system is reset accidentally, service the vehicle within 5 000 km/3,000 mi since the last service. Reset the oil life system when the oil is changed.
See Engine Oil Life System.
On vehicles with diesel engines, it is recommended to drain the diesel fuel filter of water when the oil is changed or when the WATER IN FUEL CONTACT SERVICE message displays.

(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 as indicated by the Driver Information Center (DIC) or two years whichever comes first.
The fuel filter may need to be replaced more often based on biodiesel usage, driving in climates with severe dust, off-road driving, or towing a trailer for extended periods.
(4) Or every four years, whichever comes first. If driving in dusty conditions, inspect the filter at each oil change or more often as needed.
(5) 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.
(6) Or every five years, whichever comes first. See Cooling System.
(7) Or every 10 years, whichever comes first. Inspect for fraying, excessive cracking, or damage; replace, if needed.
