GM Oil For Life System GM ENGINE OIL LIFE SYSTEM

If The Engine Oil Life System

Beginning with 2004 models, vehicle maintenance is determined through the General Motors ENGINE OIL LIFE SYSTEM. This system uses the Driver Information Center (DIC) and operates as follows:

When the CHANGE ENGINE OIL light in the (DIC) comes on, it means that service is required for your vehicle, as soon as possible, within the next 600 miles. It is possible that, if you are driving in the best conditions, the Engine Oil Life System may not indicate that vehicle service is necessary for over a year. However, your engine oil and filter must be changed at least once a year and at this time the system must be reset. Your Certified Service dealer has GM-trained service technicians who will perform this work using Genuine GM Parts and then reset the system.

NOTICE: It is important to check your oil regularly and keep it at the proper level. Failure to keep your engine oil at the proper level can cause damage to your engine not covered by your warranty.

If the Engine Oil Life System is ever reset accidentally, you must service your vehicle within 3,000 miles since your last service. Remember to reset the system whenever the oil is changed. Required services are listed as "Maintenance I" and "Maintenance II." Generally, it is recommended that your first service be Maintenance I, your second service be Maintenance II, and that you alternate I and II thereafter. However, in some cases, Maintenance II may be required more often.

MAINTENANCE I

(Use Maintenance I if the CHANGE ENGINE OIL light comes on within 10 months since the vehicle was purchased or Maintenance II was performed.)

  • Change engine oil and filter
  • Reset Oil Life System
  • Lubricate chassis components
  • Front suspension
  • Ball joints
  • Steering linkage
  • Transmission shift linkage
  • Parking brake cable guides
  • Visually check for any leaks or damage
  • Inspect engine air cleaner filter change indicator. If necessary, replace filter.* (additional charge)
  • Rotate tires and check inflation, pressure and wear.
  • Inspect brake system (Visually inspect brake lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect other brake parts, including calipers, parking brake, etc.)
  • Check engine coolant and windshield washer fluid levels and add fluid as needed.
  • Perform any Additional Required Services based on vehicle mileage. (Additional charges apply)

GM ENGINE OIL LIFE SYSTEM MAINTENANCE II

(Use Maintenance II if the previous service performed was Maintenance I. Always use Maintenance II whenever the light comes on 10 months or more since the last service, or if the light has not come on at all for one year.)

  • Change engine oil and filter
  • Reset Oil Life System
  • Lubricate chassis components
  • Front suspension
  • Ball joints
  • Steering linkage
  • Transmission shift linkage
  • Parking brake cable guides
  • Visually check for any leaks or damage
  • Inspect engine air cleaner filter change indicator. If necessary, replace filter.* (additional charge)
    Rotate tires and check inflation, pressure and wear.
  • Inspect brake system (Visually inspect brake lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect other brake parts, including calipers, parking brake, etc.)
  • Check engine coolant and windshield washer fluid levels and add fluid as needed. Perform any Additional Required Services based on vehicle mileage.)(Additional charges apply)
  • Inspect suspension and steering components. (Visually inspect front and rear suspension and steering system for damaged, loose or missing parts, signs of wear or lack of lubrication. Inspect power steering lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. Visually check constant velocity joints, rubber boots and axle seals for leaks.)
  • Inspect wiper blades. (Visually inspect wiper blades for wear or cracking. Replace blade inserts that appear worn or damaged or that streak or miss areas of the windshield.) (additional charge)
  • Inspect restraint system components. (Make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired. Have any torn or frayed safety belts replaced. Also, look for any opened or broken air bag coverings, and have them repaired or replaced.)
  • Lubricate body components. (Lubricate all key lock cylinders, hood latch assembly, secondary latch, pivots, spring anchor, release pawl, rear compartment hinges, outer liftgate handle pivot points, latch bolt, fuel door hinge, cargo door hinge, locks and folding seat hardware. More frequent lubrication may be required when exposed to a corrosive environment.)
