2010 Buick Lucerne Owner's Manual - Page 385

If this vehicle has a tire sealant and compressor kit, there may not be a spare tire, tire changing equipment, and on some vehicles there may not be a place to store a tire. The tire sealant and compressor can be used to temporarily seal punctures up to ¼ inch (6 mm) in the tread area of the tire. It can also be used to inflate an under inflated tire. If the tire has been separated from the wheel, has damaged sidewalls, or has a large puncture, the tire is too severely damaged for the tire sealant and compressor kit to be effective. See Roadside Assistance Program on page 8‑8. Read and follow all of the tire sealant and compressor kit instructions. The kit includes: A. On/Off Button B. Selector Switch (Sealant/Air or Air Only) C. Pressure Relief Button D. Pressure Gauge E. Air Only Hose (Black) F. Sealant/Air Hose (Clear) G. Power Plug 6-83
