How This Section is Organized The remainder of this section is divided into five parts: shows "Part A: Scheduled Maintenance Services" what to have done and how often. Some of these services can be complex, so unless you are technically qualified and have the necessary equipment, you should let your dealer's service department or anotherqualified service centerdo these jobs. tells "Part B: Owner Checks and Services" you what should be checked and when. It also explains what you can easily do to help keep your vehiclein good condition. explains "Part C: Periodic Maintenance Inspections" important inspections that your GM dealer's service department or another qualified service center should perform. lists "Part D: Recommended Fluids and Lubricants" some products GM recommends to help keep your vehicle properly maintained. These products, or their equivalents, should be used whether you do the work yourself or have it done. "Part E: Maintenance Record" provides a place for you to record the maintenance performed on your vehicle. Whenever any maintenance is performed, be sure to write it down in this part. This will help you determine when your next maintenance should be done. In addition, it is a good idea to keep your maintenance receipts. They may be needed to qualify your vehicle for warranty repairs. Performing maintenance work on vehicle can a be dangerous. In trying to do some jobs, can you be seriously injured. Do your own maintenance work only if you have the required know-how and the propertools and equipment for the job. If you have any doubt, have a qualified technician do the work. If you are skilled enough to do some work on your vehicle, you will probably want to get the service information GM publishes. See "Service and Owner Publications" in the Index. 7-3
