Finis,h Damage
Any stone chips, fractures or deep scratches in the fini.sh
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.
Un,derbody Maintenance
Chemicais used €or 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 atmosphexic conditions can create a
chemical fallout. Airborne pollutants can fall 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 surface.
Although no defect in the paint job causes this, Buick
will repair, at no chaKge 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 comes first.

you to be happy with it.

service needs, you’ll
know that GM-trained and
supported service people will perform the work using
genuine GM parts.
These schedules are
for vehicles that:

limits.
You will find these limits on your vehicle’s
Tire-Loading Information label. See “Loading Your
Vehicle” in the Index.
are driven on reasonable road surfaces within legal
driving limits.
a use the recommended unleaded fuel. See “Fuel” in
the Index.

right for your vehicle. Here’s how to decide which
schedule to follow:

door-to-door .deliveryy or in stop-and-go traffic).
0 You operate your vehicle in dusty areas.
