GMC 2007 Acadia - Manual (Page 387)

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 535.
Your vehicle has an airbag system. Before
attempting to do your own service work, see
Servicing Your Airbag-Equipped Vehicle on
page 90.
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
on page 514.
Adding Equipment to the Outside
of Your Vehicle
Things you might add to the outside of your
vehicle can affect the airflow around it. This may
cause wind noise and affect windshield washer
performance. Check with your dealer/retailer
before adding equipment to the outside of your
vehicle.
Fuel
Use of the recommended fuel is an important
part of the proper maintenance of your vehicle.
To help keep the engine clean and maintain
optimum vehicle performance, we recommend
the use of gasoline advertised as TOP TIER
Detergent Gasoline.
