AC’
Service
Your Pontiac 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.
Doing Your Own Service Work
If you want to do some of your own
service work, you’ll want to get the
proper Pontiac Service Manual. It
tells you much more about how to service
your Pontiac than this manual can. To
order the proper service manual, see the
Index under Service Publications.
You should keep a record with all parts
receipts and list the mileage and date
of
any service work you perform. See the
Index under Maintenance Record.
