Air Conditioner (Option)
The air conditioner cools the air coming into your
vehicle. The air conditioner won’t .work, well unless all
the windows are closed. On a very hot day, you might
want to open the windows to let the hottest air out.
Max
This setting provides maximum cooling with the least
amount of work. MAX recirculates the air inside your
vehicle, and cools the air quickly. Adjust the
temperature control to a cold setting.
Norm.
After using the MAX setting to cool the air quickly,
adjust the air conditioner to NORM and the temperature
to the desired comfort setting. This permits fresh air to
be cooled and to circulate through your vehicle.
Audio Systems
Your Delcoa audio system has been degigned to operate
easily and give years
of listening pleasure. But you will
get the most enjoyment out
of your system if you
acquaint yourself with it first. Find out what your
Delcom system can do and how to operate all its
controls,
to be sure you’re getting the most out of the
advanced engineering that went into it.
FM Stereo
FM stereo will give you the best sound. But FM signals
will reach only about
10 to 40 miles (16 to 65 km). And,
tall buildings or hills can interfere with FM signals, causing the sound to come and go.
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines.
Try
reducing the treble to reduce this noise.

The tire has a puncture, cut, or other damage that
can’t be repaired well because of the size or location
of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get new tires, get ones with that same
TPC Spec number. That way,
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on
your vehicle. If your tires have an all-season tread
design, the TPC number will be followed by a
“MS”
(for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.
A CAUTION:
Mixing tires could cause you to lose control
while driving.
If you mix tires of different sizes or
types (radial and bias-belted tires), the vehicle
may not handle properly, and you could have a
crash. Be sure to use the same size and type
tires on all wheels.
It’s all right to drive with your compact spare,
though. It was developed for limited use on your
vehicle.

Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration which grades tires by
treadwear, traction and temperature performance. (This applies only to vehicles sold in the United States.)
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded
150 would wear one and a half
245

In most cases, you will not need to have your wheels
. aligned again. However, if you notice unusual tire wear or your vehicle pulling one way or the other, the
alignment may need to be reset. If you notice your
vehicle vibrating when driving on a smooth road, your
wheels may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted.
If wheel nuts keep coming loose, the wheel, wheel bolts,
and wheel nuts should be replaced. If the wheel leaks air out, replace it (except some aluminum wheels, which
can sometimes be repaired
-- See your Buick dealer) if
any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load carrying
capacity, diameter, width, offset, and be mounted the
same way
as the one it replaces.
If you need to replace any of your wheels, wheel bolts,
or wheel nuts, replace them only with new
GM original
equipment parts. This way, you will be sure to. have the
right wheel, wheel bolts, and wheel nuts for your Buick
model.
A CAUTION:
Using the wrong replacement wheels, wheel
bolts, or wheel nuts
on your vehicle can be
dangerous.
It could affect the braking and
handling
of your vehicle, make your tires lose
and make you lose control. You could have a
collision
in which you or others could be injured.
Always use the correct wheel, wheel bolts, and
wheel nuts for replacement

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.
x
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 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 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 comes first.
