GMC 2007 Yukon XL Owner's Manual page 554

CAUTION:
{
Performing maintenance work on a
vehicle can be dangerous. In trying to do
some jobs, you can be seriously injured.
Do your own maintenance work only if
you have the required know-how and the
proper tools and equipment for the job.
If you have any doubt, see your GM
®
Goodwrench dealer to have a qualified
technician do the work. See Doing Your
Own Service Work on page 427.
Some maintenance services can be complex.
So, unless you are technically qualified and have
the necessary equipment, you should have
your GM Goodwrench
554
®
dealer do these jobs.
When you go to your GM Goodwrench
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 590.
Owner Checks and Services on page 560 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 564 and Normal
Maintenance Replacement Parts on page 566.
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.
