9-4 Vehicle Service and Care If you want to do some of your own service work, you should use the proper service manual. It tells you much more about how to service your vehicle than this manual can. To order the proper service manual, see Service Publications Ordering Information on page 11-14. Your vehicle has an airbag system. Before attempting to do your own service work, see Airbag System Check on page 1-36. You should keep a record with all parts receipts and list the mileage and the date of any service work you perform. See "Maintenance Record" in the Limited Warranty, Maintenance and Owner Assistance Information manual. Doing Your Own Service Work Adding Equipment to the Outside of the Vehicle Things you might add to the outside of your vehicle can affect the airflow around it. This can cause wind noise and can affect fuel economy and windshield washer performance. Check with your dealer/retailer before adding equipment to the outside of your vehicle. { CAUTION You can be injured and your vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it. • Be sure you have sufficient knowledge, experience, the proper replacement parts, and tools before you attempt any vehicle maintenance task. • Be sure to use the proper nuts, bolts, and other fasteners. English and metric fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt.
