10-4 Vehicle Care Damage to vehicle components resulting from modifications or the installation or use of non‐GM certified parts, including control module or software modifications, is not covered under the terms of the vehicle warranty and may affect remaining warranty coverage for affected parts. GM Accessories are designed to complement and function with other systems on the vehicle. See your dealer to accessorize the vehicle using genuine GM Accessories installed by a dealer technician. Also, see Adding Equipment to the Airbag-Equipped Vehicle on page 3‑31. Vehicle Checks Doing Your Own Service Work { WARNING It can be dangerous to work on your vehicle if you do not have the proper knowledge, service manual, tools, or parts. Always follow owner manual procedures and consult the service manual for your vehicle before doing any service work. If doing some of your own service work, use the proper service manual. It tells you much more about how to service the vehicle than this manual can. To order the proper service manual, see Service Publications Ordering Information on page 13‑11. This vehicle has an airbag system. Before attempting to do your own service work, see Servicing the Airbag-Equipped Vehicle on page 3‑31. Keep a record with all parts receipts and list the mileage and the date of any service work performed. See Maintenance Records on page 11‑13.
