GMC 2007 Yukon XL, Owner'S Manual

Some maintenance services can be complex. So,
unless you are technically qualified and have
the necessary equipment, you should have your
GM Goodwrench
®
dealer do these jobs.
When you go to your GM Goodwrench
®
dealer for
your service needs, you will know that GM-trained
and supported service technicians will perform
the work using genuine GM parts.
If you want to purchase service information, see
Service Publications Ordering Information on
page 613.
Owner Checks and Services on page 584 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 588 and Normal
Maintenance Replacement Parts on page 590.
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 GM parts.
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 may not
indicate that vehicle service is necessary for over
a year. However, your engine oil and filter
must be changed at least once a year and at this
time the system must be reset. Your GM
Goodwrench
®
dealer has GM-trained service
technicians who will perform this work using
genuine GM 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 466 for information on the Engine Oil Life
System and resetting the system.
