General Information

Your vehicle is an important investment. This section describes the required maintenance for the vehicle. Follow this schedule to help protect against major repair expenses resulting from neglect or inadequate maintenance. It may also help to maintain the value of the vehicle if it is sold. It is the responsibility of the owner to have all required maintenance performed.

Your dealer has trained technicians who can perform required maintenance using genuine replacement parts. They have up-to-date tools and equipment for fast and accurate diagnostics. Many dealers have extended evening and Saturday hours, courtesy transportation, and online scheduling to assist with service needs. Your dealer recognizes the importance of providing competitively priced maintenance and repair services. With trained technicians, the dealer is the place for routine maintenance such as oil changes and tire rotations and additional maintenance items like tires, brakes, batteries, and wiper blades.

Caution
Damage caused by improper maintenance can lead to costly repairs and may not be covered by the vehicle warranty. Maintenance intervals, checks, inspections, recommended fluids, and lubricants are important to keep the vehicle in good working condition.

Do not have chemical flushes that are not approved by GM performed on the vehicle. The use of flushes, solvents, cleaners, or lubricants that are not approved by GM could damage the vehicle, requiring expensive repairs that are not covered by the vehicle warranty. Because of the way people use vehicles, maintenance needs vary. There may need to be more frequent checks and services. The Additional Required Services – Normal are for vehicles that The Tire Rotation and Required Services are the responsibility of the vehicle owner. It is recommended to have your dealer perform these services every 12 000 km/7,500 mi.
Proper vehicle maintenance helps to keep the vehicle in good working condition, improves fuel economy, and reduces vehicle emissions.

Warning
Performing maintenance work can be dangerous and can cause serious injury. Perform maintenance work only if the required information, proper tools, and equipment are available. If they are not, see your dealer to have a trained technician do the work. See Doing Your Own Service Work 0 262.

Maintenance Schedule

Tire Rotation and Required Services Every 12 000 km (7,500 mi) Tires are rotated to achieve a more uniform wear for all tires. The first rotation is the most important. Anytime unusual wear is noticed, rotate the tires as soon as possible, check for proper tire inflation pressure, and check for damaged tires or wheels. If the unusual wear continues after the rotation, check the wheel alignment. See When It Is Time for New Tires 0 341 and Wheel Replacement 0 344

• Perform Multi-Point Vehicle Inspection. See Multi-Point Vehicle Inspection (MPVI) 0 369.
• Lubricate body components. See Exterior Care 0 356.

Additional Required Services — Normal Service
Every 12 000 km (7,500 mi).

• Check the engine oil level and oil life percentage. If needed, change the engine the oil, and filter, and reset oil in the life system. Or 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 0 270.

• When the REPLACE AT NEXT OIL CHANGE message displays, the engine air filter should be replaced at the next engine oil change. When the REPLACE ENGINE AIR
  FILTER SOON message displays, the engine air filter should be replaced at the earliest convenience. Reset the engine air filter life system after the engine air filter is replaced. See Engine Air Filter Life System 0 271.
  Every 36 000 km (22,500 mi)
• Replace the passenger compartment air filter. Or every 24 months, 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.
  Every 96 000 km (60,000 mi)
• Replace spark plugs. (2.0L L4 Engine Only.)
  Inspect spark plug wires and/or boots.

Every 156 000 km (97,500 mi)

• Replace spark plugs. (3.6L V6 Engine Only.) Inspect spark plug wires and/or boots.
  Every 161 000 km (100,000 mi)
• Replace hood and/or body lift support gas struts. Or every 10 years, whichever comes first. See Gas Strut(s) 0 282.
  Every 240 000 km (150,000 mi)
• Change rear axle fluid, if equipped with AWD. 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 transfer case fluid. Contaminated fluid will decrease the life of the transfer case and/ or axles and should be replaced.
• Drain and fill the engine cooling system. Or every six years, whichever comes first.

See Cooling System 0 272. Severe Conditions Requiring More
