GMC 2006 Sierra - Manual (Page 551)

Using the Maintenance Schedule
We at General Motors want to help you keep your vehicle
in good working condition. But we do not know exactly
how you will drive it. You may drive very short distances
only a few times a week. Or you may drive long distances
all the time in very hot, dusty weather. You may use your
vehicle in making deliveries. Or you may drive it to work,
to do errands, or in many other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You may need more
frequent checks and replacements. So please read
the following and note how you drive. If you have any
questions on how to keep your vehicle in good condition,
see your GM Goodwrench
® dealer.
This schedule is for vehicles that:
• carry passengers and cargo within recommended
limits. You will find these limits on the tire and loading
information label. See Loading Your Vehicle on
page 4-48.
• are driven on reasonable road surfaces within legal
driving limits.
• are driven off-road in the recommended manner.
See Off-Road Driving on page 4-16.
• use the recommended fuel. See Gasoline Octane on
page 5-6.
The services in Scheduled Maintenance (Gasoline
Engine) on page 6-4 should be performed when
indicated. See Additional Required Services (Gasoline
Engine) on page 6-7 and Maintenance Footnotes
(Gasoline Engine) on page 6-9 for further information.
{ 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 5-5.
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.
