Ventilation Tips 
Keep the hood  and front  air  inlet  free 
of  ice,  snow,  or  any  other obstruction 
(such  as leaves). The  heater  and 
defroster  will  work  far  better, 
reducing  the chance 
of fogging  the 
inside  of your  windows. 
In  cold  weather,  turn  the blower  fan 
to 
HI for  a  few moments  before 
driving  off.  This  helps  clear  the intake 
ducts  of snow  and  moisture,  and 
reduces  the chance  of fogging  the 
inside  of your  windows. 
Keep  the air  path  under the front 
seats  clear of objects.  This  helps  air  to 
circulate  throughout  your  vehicle. 
Audio Systems 
The  following  pages  describe  the audio 
systems  available  for  your  Chevrolet, 
and  how  to get  the  best  performance 
from  them.  Please  read  about the 
system  in  your  vehicle. 
Hearing  damage  from  loud  noise  is 
almost  undetectable  until  it  is  too late. 
Your  hearing  can  adapt to higher 
volumes 
of sound.  Sound that seems 
normal  can  be  loud  and harmful  to your 
hearing.  Take  precautions  by adjusting 
the  volume  control  on your  radio  to a 
safe  sound  level  before  your  hearing 
adapts  to it. 
To help  avoid  hearing loss 
or  damage: 
Adjust  the volume  control  to  the

comfortably  and  clearly. 
NOTICE: 
Before  you  add  any  sound 
equipment  to your  vehicle 
- like  a 
tape  player, 
CB radio,  mobile 
telephone  or two-way  radio 
- be 
sure  you 
can add  what  you want.  If 
you  can,  it’s  very  important  to do  it 
properly.  Added  sound  equipment 
may  interfere  with  the operation  of 
your  vehicle’s  engine,  DelcoB  radio  or  other  systems,  and  even  damage 
them. And,  your  vehicle’s  systems 
may  interfere  with  the operation  of 
sound  equipment  that has  been 
added  improperly. 
So, before 
adding  sound  equipment,  check 
with  your  dealer  and be sure  to 
check  Federal  rules  covering  mobile 
radio  and telephone  units.

Understanding  Radio  Reception 
FM Stereo 
FM Stereo  will  give you the best  sound, 
but  FM  signals 
will reach only about 10 
to 40 miles (16 to 65 la). 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  also  pick up noise  from  things 
like  storms and  power  lines.  To lower 
this  noise, 
try reducing  the treble  level. 
Care of Your  Cassette  Tape 
Player 
A tape  player  that is not  cleaned 
regularly 
is subject  to reduced  sound 
quality,  ruining  the cassette,  or 
damaging  the mechanism.  Tape 
cassettes  that  are not properly  stored  in 
their  plastic  cases  away  from 
contaminants,  direct  sunlight,  and 
extreme  heat may not operate  properly 
and could  cause  premature  failure  of I' 
the tape  player. 
Your tape player  should  be cleaned 
monthly  or  with  every 
15 hours  of use, 
as regular  maintenance.  If you  notice  a ll 
reduction  in sound  quality, try a good 
cassette  to see 
if the  tape  or the tape 
player  is  at fault.  If the  second  cassette 
results  in no  improvement  in sound
