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 13‑18.
This vehicle has an airbag system.
Before attempting to do your own service work, see Servicing the Airbag-Equipped Vehicle on page 3‑35.
Keep a record with all parts receipts and list the mileage and the date of any service work performed.
See Maintenance Records on page 11‑14.
