Battery  Warning  Light Voltmeter  Gage 
If this  light is displayed 
when  the engine  is 
running,  you  may  have a 
problem  with  your  charging 
system. 
The  battery  display  will  also stay on while  the key  is in 
RUN  until  the  engine  is  started. 
If the  light  stays  on  after starting the  engine  it  could 
indicate  a  problem  with  the generator  drive  belt, or  some 
other  charging  system  problem.  Have  it  checked right 
away.  Driving  with  this light displayed could drain 
your  battery. 
If you  must  drive  a  short  distance with this  light 
displayed,  it  helps  to turn 
off all your  accessories,  such 
as  the  radio  and  the  air  conditioner.  When  your 
engine is not  running, but the  ignition  is  in 
RUN,  this gage  shows your battery’s state  of charge  in 
DC volts. 
When  the engine  is running,  the gage shows the 
condition  of the charging  system. Readings between the 
low and high warning  zones indicate the  normal 
operating  range. 
Readings  in the  low  warning  zone  may occur when  a 
large  number 
of electrical accessories are operating  in 
the vehicle and the  engine is left  at an  idle for  an 
extended  period. This condition 
is normal since the 
charging  system is not  able to  provide full  power 
at  engine  idle. 
As engine speeds  are increased, this 
condition should correct  itself as higher  engine speeds 
allow the charging system to create maximum  power.

Audio System@) 
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, 
Delphi  Electronics  radio  or  other  systems,  and 
even  damage  them.  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. 
Your  audio  system  has  been designed to operate easily 
and  to  give  years  of listening  pleasure.  You  will get 
the  most  enjoyment  out  of it 
if you  acquaint  yourself  with 
it  first.  Find out  what  your  audio  system  can do and 
how  to  operate  all of its  controls  to  be sure you’re getting 
the  most  out  of the  advanced  engineering that  went 
into  it.  Your  vehicle 
may have a feature called Retained 
Accessory  Power  (RAP).  With RAP,  you can play your 
audio  system even after the ignition is turned 
off. 
See “Retained  Accessory  Power  (RAP)” under Ignition 
Positions  on  page
