GMC 2007 Acadia - Manual (Page 502)

When you go to your dealer/retailer for your
service needs, you will know that trained and
supported service technicians will perform the work
using genuine parts.
If you want to purchase service information, see
Service Publications Ordering Information on
page 535.
Owner Checks and Services on page 507 tells you
what should be checked, when to check it, and
what you can easily do to help keep your vehicle in
good condition.
The proper replacement parts, fluids, and
lubricants to use are listed in Recommended
Fluids and Lubricants on page 511 and Normal
Maintenance Replacement Parts on page 512.
When your vehicle is serviced, make sure these
are used. All parts should be replaced and all
necessary repairs done before you or anyone else
drives the vehicle. We recommend the use of
genuine parts from your dealer/retailer.
Scheduled Maintenance
When the CHANGE ENGINE OIL SOON message
comes on, it means that service is required for your
vehicle. Have your vehicle serviced as soon as
possible within the next 600 miles (1 000 km). It is
possible that, if you are driving under the best
conditions, the engine oil life system might not
indicate that vehicle service is necessary for over a
year. However, the engine oil and filter must be
changed at least once a year and at this time the
system must be reset. Your dealer/retailer has
trained service technicians who will perform this
work using genuine parts and reset the system.
If the engine oil life system is ever reset
accidentally, you must service your vehicle within
3,000 miles (5 000 km) since your last service.
Remember to reset the oil life system whenever
the oil is changed. See Engine Oil Life System on
page 400 for information on the Engine Oil Life
System and resetting the system.
