Understanding  Radio  Reception 
FM stereo will give  you  the  best sound. But FM signals will reach only 
about 
10 to 40 miles (I 6 to 65 km). And, tall buildings  or hills can interfere 
with  FM signals,  causing  the sound to  come and go. 
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  stornx and power  lines.  Try reducing 
the  treble 
to reduce  this noise if you  ever  get  it. 
AM  Stereo  means the  Delco‘ system can  receive C-QUAM“stereo 
broadcasts.  Many  AM stations around the  county 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-QUAMa,  your 
“STEREO” light will come on when you’re  receiving  it.

A CAUTION: 
If your vehicle  has air conditioning,  the auxiliary electric  fan 
under  the  hood can 
start up even  when  the engine is not  running 
and  can injure  you.  Keep  hands, clothing  and 
tools away from 
any underhood electric  fan. 
- 
NOTICE: 
Ignoring these steps could result  in  costly  damage to your 
vehicle  that wouldn’t  be  covered  by  your vehicle  warranty. 
Trying  to  start  your vehicle  by  pushing or pulling it  could 
damage your  vehicle,  even  if  you  have a manual transmission. 
And  if  you  have an automatic transmission, 
it won’t  start  that 
way. 
To Jump Start Your Vehicle 
1. Check  the other  vehicle.  It must have a 12-volt  battery  with  a negative 
ground  system. 
NOTICE: 
If the  other  system  isn’t  a 12-volt  system  with  a negative 
ground, both  vehicles can be damaged. 
If you  have  a  diesel engine  vehicle  with two batteries  (or more), you 
should  know before  you begin  that,  especially in cold weather, you  may 
not be  able  to  get  enough  power  from a  single  battery 
in another 
vehicle  to  start your  diesel  engine. 
If your vehicle  has more than  one battery,  use the battery  that’s on the 
passenger  side 
of the vehicle - this will  reduce  electrical  resistance. 
2. Get  the  vehicles  close  enough so the jumper  cables can reach,  but  be 
sure  the vehicles aren’t  touching  each other. 
If they are, it could  cause  a 
ground  connection  you don’t  want. 
You wouldn’t  be  able  to start your 
vehicle,  and the bad  grounding could damage 
the electrical  systems.
