This light should come’ on as you start the vehicle. If it
doesn’t corne on then, have it fixed

if there’s a problem.
This light will also come on when you set your parking
brake,

fully released,
it means you have a brake problem. If the
light comes on while driving, p.d off the- road and stop
carefully. You may notice that the pedal is harder
to
push. Or, the pedal may go closer to the floor. It may
take longer to stop.

vehicle towed for service. (See “Towing Your Car” in
the Index.)

stop as soon as possible and turn the key
off. Then start
the engine to reset the system.

anti-lock brakes.

light is also
on, see “Brake System Warning Light”
earlier
in this part.

on when you are driving with
a compact spare. tire, If
this happens, the light means you won’t have anti-lo,ck
until you replace the compact spare ,with
.a fuU-simtire.
If the anti-lock brake system warning light stays
on after
you replace the compact spare with a full-size tire, or if
it comes
on again when you’re driving, your Buick
needs service.

the sun may adequately warm your upper body, but your
lower body may not be warm enough.
The Bi-level settbg directs outside air.into your vehicle
in two ways.-Cool air
is directed 'toward your upper
body through the front instrument panel outlets, ,while
slightly warmed
air is directed through the heater outlet
at
your feet.
.The air conditioner compressor operates in all Air
Conditioning positions, and the Defrost position when
.the outside temperature is above
40 OF (4.5 C).
R
Ventilation
For mild outside temperatures, when little heating ox ,
cooling is needed, slide the upper lever to Vent, Air will,'
flow through the .instrument panel outlets. Use the air
oudets to turn on, adjust and turn
off the air, flow. Adjust.
the lower lever to control the temperature;
'.
.. .
Heating
When outside temperatures are cold, 8liding:the upper .
lever to Heater and the' lower lever to :Warm will send,
heated air though the heater outlets, 'and-some through
the defroster vents. Vent and Heater arelabeled
economy positions. because the
dr conditioner
compres.sor doesn't run in these..two settings. "This . .
reduces engine load, resulting in impioyed I.. fyd.
economy.
Defrosting
The Defrost setting directs most of the- air through the
defroster vents, and some through.the heater outlets. Use
defrost when you want to remove fog
,6r ice from the
windshield.

AM Stereo
This means the Delco@ system can receive C-QUAM@
stereo broadcasts. Many
AM stations around the country
use C-QUAM@ to produce stereo, though
some do not.
(C-QUAM@ is
a registered trademark of Motorola, Inc.)
If your Delco@ system can get C-QUAM@, your
“STEREO” light will come on when you’re receiving it.

undetectable until it is too late. Your hearing
can adapt to higher volumes
of sound. Sound
that seems normal can be

your hearing. Take precautions by adjusting the
volume control on your radio
to a safe =T)UP~
level before your hearing adapts to it.

C-are of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes, or a damaged mechanism. Cassette -tapes should be stored in. their
cases away from contaminants, direct sunlight, and
extreme heat. If they aren’t, they may not operate
properly or cause failure
of the tape player.
I Your tape player should be cleaned regularly each
month or after every
15 hours of use. If you notice a
reduction in sound quality, try a known good cassette to
see
if the tape or the tape player is at fault. .E this other
