Doing Your Own Service Work; Adding Equipment To The Outside Of Your Vehicle - GMC SIERRA DENALI 2003 Manual

Doing Your Own Service Work
If you want to do some of your own service work, you'll
want to 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 7- IO.
Your vehicle has an air bag system. Before attempting
to do your own service work, see Servicing Your Air
Bag-Equipped Vehicle on page 1-72.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See Pat? E: Maintenance Record on page 6- 18.
.3u can be injured and your vehicle could be
damaged if you try to do service work on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. "English" and "metric"
fasteners can be easily confused. If
you
use the wrong fasteners, parts can later
break or fall off.
You
could be hurt.
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 before adding equipment to
the outside of your vehicle.
