GMC 2003 Yukon XL, Owner'S Manual

Page: 471 / 518

How This Section is Organized
This maintenance schedule is divided into five parts:
“Part A: Scheduled Maintenance Services” explains
what to have done and how often. Some of these
services can be complex, so unless you are technically
qualified and have the necessary equipment, you
should let your GM dealer’s service department do
these jobs.
Your GM dealer has GM-trained and supported
service people that will perform the work using genuine
GM parts.
{
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,
have a qualified technician do the work.
If you want to get the service information, see Service
Publications Ordering Information on page 7-10.
“Part B: Owner Checks and Services” tells you what
should be checked and when. It also explains what
you can easily do to help keep your vehicle in good
condition.
“Part C: Periodic Maintenance I nspections” explains
important inspections that your dealer’s service
department can perform for you.
“Part D: Recommended Fluids and Lubricants” lists
some recommended products necessary to help
keep your vehicle properly maintained. These products,
or their equivalents, should be used whether you do
the work yourself or have it done.
“Part E: Maintenance Record” is a place for you to
record and keep track of the maintenance performed on
your vehicle. Keep your maintenance receipts. They
may be needed to qualify your vehicle for warranty
repairs.
