Service Doing Your Own Service Work
Your dealer knows your vehicle best and wants you to
be happy with it. We hope you'll go to your dealer for
all your service needs. You'll get genuine GM parts and
GM-trained and supported service people.
We hope you'll want to keep your GM vehicle all GM.
Genuine GM parts have one of these marks:
Genuine
If you want to do some of your own service work, you'll
want to use the proper Chevrolet 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 and Owner Publications'' in the Index.
Your vehicle has an air bag system. Before attempting to
do your own service work, see "Servicing Your Air
Bag-Equipped Vehicle'' in the Index.
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 Index.
