2009 GMC SIERRA 1500 fuel

Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on the underbody. If these are
not removed, corrosion and rust can develop on the
underbody parts such as fuel lines, frame, oor pan,
and exhaust system even though they have corrosion
protection.
At least every spring, ush these materials from the
underbody with plain water. Clean any areas where
mud and debris can collect. Dirt packed in close areas
of the frame should be loosened before being ushed.
Your dealer/retailer or an underbody car washing system
can do this.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces on the vehicle. This damage
can take two forms: blotchy, ring-shaped discolorations,
and small, irregular dark spots etched into the paint
surface.
Although no defect in the paint job causes this, we
will repair, at no charge to the owner, the surfaces
of new vehicles damaged by this fallout condition within
12 months or 12,000 miles (20 000 km) of purchase,
whichever occurs rst.
Vehicle Identication
Vehicle Identication Number (VIN)
This is the legal identier for the vehicle. It appears on
a plate in the front corner of the instrument panel, on the
driver side. It can be seen through the windshield from
outside the vehicle. The VIN also appears on the
Certication/Tire and Service Parts labels and the
certicates of title and registration.
Engine Identication
The eighth character in the VIN is the engine code.
This code helps identify the vehicle’s engine,
specications, and replacement parts. See “Engine
Specications” underCapacities and Specifications
on page 5-131for the vehicle’s engine code.

Using the Maintenance Schedule
We want to help keep this vehicle in good working
condition. But we do not know exactly how you will
drive it. You might drive very short distances only a
few times a week. Or you might drive long distances
all the time in very hot, dusty weather. You might use
the vehicle in making deliveries. Or you might 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 might 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 the vehicle in good condition,
see your dealer/retailer.
This schedule is for vehicles that:
carry passengers and cargo within recommended
limits on the Tire and Loading Information label.
SeeLoading the Vehicle on page 4-34.
are driven on reasonable road surfaces within legal
driving limits.
are driven off-road in the recommended manner.
SeeOff-Road Driving on page 4-13.

Engine) on page 6-4should be performed when
indicated. SeeAdditional Required Services on page 6-7
andMaintenance Footnotes on page 6-9for 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 dealer/retailer to have a
