The other label is the Certification label, found on the
rear edge of the driver’s door. It tells you the
gross
weight capacity of your vehicle, called the GVWR (Gross
Vehicle Weight Rating). The
GVWR includes the weight
of the vehicle, all occupants, fuel and cargo. Never
exceed the GVWR for your vehicle, or the Gross Axle
Weight Rating
(GAWR) for either the front or rear axle.
And, if you do have a heavy load, YOU should spread it
out. Don’t carry more than

If you put things inside your vehicle -- like suitcases,
tools, packages, or anything else
-- they will go as fast

is a crash, they’ll keep going.

Weatherstrips
-These are places where glass or metal meets rubber.
Silicone grease there will make them last longer, seal
better, and not squeak. Apply silicone grease with a
clean cloth at least every six months.
Sheet Metal Damage
.If your vehicle is damaged and requires sheet metal
.repair or replacement, make sure the body repair shop
: applies anti-corrosion material to the parts repaired or
replaced to restore corrosion protection.
-Foreign Material
Calcium chloride and other salts, ice melting agents,
road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, and other foreign matter can
damage your vehicle’s finish if they remain on painted
surfaces. Use cleaners that are marked safe for painted
surfaces for these stains.
Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal will corrode
quickly and may develop into a major repair expense. Minor chips and scratches can be repaired with touch-up
materials available fi-om your dealer
or other service
outlets. Larger areas of finish damage can be corrected
in your dealer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect
on the underbody. If these are not
removed, accelerated corrosion (rust) can occur on the Underbody parts such as fuel lines, frame, floor pan, and
exhaust system even though
they have corrosion
protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and other debris can collect. Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your dealer or an underbody vehicle washing system
can do this for you.

If YOU are skilled enough to do some work on your
vehicle, you will probably want to get the service
information GM publishes. You will find a list of
publications and how to get them in this manual. See
“Service Publications” in the Index.
“Section B: Owner Checks and Services” tells you what
should be checked whenever you stop for fuel. It also
explains what you can easily do to help keep your vehicle in good condition.
“Section C: Periodic Maintenance Inspections” explains
important inspections that your Buick dealer’s service
department or another qualified service center should
perform. ‘‘Section D: Recommended Fluids and Lubricants” lists
some products GM recommends 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.
“Section
E: Maintenance Record” provides a place for
you to record the maintenance performed on your
vehicle. Whenever any maintenance is performed, be sure
to write it down in this section. This will help you
determine when your next maintenance should be done.
In addition, it is a good idea to keep your maintenance
receipts. They may be needed to qualify your vehicle for
warranty repairs.
