I Introduction A Word About Maintenance We at General Motors want to help you keep your vehicle in good working condition. But we don't know exactly how you'll drive it. You may drive very short distances only a few times a week. Or you may drive long distances allthe time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands or in many other ways. Because of all thedifferent ways people use their GM vehicles, maintenance needs vary. You may even need more frequent checksand replacements than you will find in the schedules in this part. So please read this part and notehow you drive. If you have any questions on how to keep your vehicle in good condition, see your Buick dealer, the place many GM owners chooseto have their maintenance work done.
