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.
In the trunk or rear area don’t carry more than 160
pounds (72 kg) for the coupeshedans; 300 pounds (136 kg) for the six-passenger wagon.
If you have the eight-
passenger wagon, no additional cargo
can be carried if
you already have eight people in the vehicle.
A CAUTION:
Do not load your vehicle any heavier than the
GVWR or the maximum front and rear GAWRs.
If you do, parts on your vehicle can brerak, or It
can change the way your vehicle handles.
These could cause you to lose control. Also,
overloading can shorten the life of your
vehicle.
If you put things inside your vehicle-like suitcases,
tools, packages, or anything else-they willgo as hst
as
the vehicle goes. If you have to stop or turn quickly, or if
there is a crash, they’ll keep
going.

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 from 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.
Chemical paint Spotting
Some weather and atmospheric conditions can create a
chemical fdlout. Airborne pollutants can
f$ll upon and
attack painted surfaces on your vehicle. This damage can
take
two forms: blotchy, ringlet-shaped discolorations,
and small irregular dark
spots etched into the paint
surhce.
Although no defect in the paint job causes
this, Buick
will repair, at no charge to the owner, the surfaces
of new
vehicles damaged by this fallout condition within 12
months or 12,OOO miles (20 OOO km) of purchase,
whichever comes first.
