How to Use This Manual 
Many  people  read  their  owner’s  manual  from beginning to end when they 
first receive  their  new  vehicle.  This will help you learn  about  the  features 
and  controls  for- your vehicle. 
In this manual, you’ll find  that  pictures  and 
words  work  together to  explain  things quickly. 
INDEX: A good place  to  look  for what you need is the  Index in back of the 
manual.  It’s  an  alphabetical  list 
of all  that’s in the  manual,  and the page 
number  where  you’ll  find 
it. 
SECTION 1-6: Each  section of this  manual  begins with a brief  list  of  its 
contents, 
so you  can  often  find  at a glance if a section  contains  the 
information  you want. 
SECTION 7: This  section of the  manual  covers the  maintenance  required 
for your  vehicle. 
SECTION 8 CUSTOMER  ASSISTANCE: This section  includes 
important  information  about  reporting  safety  defects and gives  you details 
about  the  “Roadside  Assistance”  program.  You will also  find  customer 
satisfaction  phone  numbers  (including customer satisfaction  numbers  for the 
hearing  and  speech  impaired) 
as well  as  the  mediation/arbitration  procedure. 
We’ve  also included  ordering information  for service  publications  in  this 
part. 
Safety Warnings and Symbols 
You will find a  number of safety  cautions in this  book.  We  use a box  with 
gray  background  and 
the word CAUTION to  tell you about  things  that  could 
hurt 
you if you  were  to  ignore the  warning. 
A CAUTION: 
These  mean  there is something  that could hurt you or other 
people. 
In  the  gray  caution area,  we  tell  you  what the hazard is. Then  we tell you 
what  to  do to help avoid or reduce  the  hazard.  Please  read  these  cautions. 
If 
you don’t, you or others  could  be  hurt. 
You  will also 
find a circle  with a slash  through it in this  book. This safety 
symbol  means  “Don’t,’’  “Don’t 
do this,” or “Don’t let this  happen.’’

FM Stereo 
FM stereo will give you the best  sound. But  FM  signals can only  reach 
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 electrical  storms and power lines. If 
the noise interferes  with your listening,  try reducing  the treble to lessen the 
noise. 
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. If your Delco@ system can get C-QUAM@, your 
“STEREO” light  will come  on  when  you’re receiving it. (C-QUAM’  is a 
registered  trademark of Motorola, Inc.). 
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,  Delco@  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.

Driving  too fast through  large  water  puddles  or even  going  through  some 
car  washes  can  cause  problems, 
too. The  water  may  affect  your  brakes. Try 
to  avoid  puddles.  But if you  can’t,  try  to  slow  down  before  you  hit  them. 
Hydroplaning 
Hjdroplaning is  dangerous. So much  water  can  build  up  under  your  tires 
that  they  can  actually  ride on  the  water.  This  caa happen  if  the  road  is wet 
enough  and you’re  going  fast enough.  When  your  vehicle 
is hydroplaning, it 
has little or  no  contact  with  the  road. 
Hydroplaning  doesn’t  happen  often.  But  it can 
if your  tires  haven’t  much 
tread  or 
if the  pressure  in one  or  more  is low.  It can  happen  if a lot of water 
is  standing  on  the  road.  If  you  can  see  reflections  from  trees,  \
telephone 
poles, 
or other  vehicles,  and  raindrops  “dimple”  the water’s  sudace,  there 
could  be  hydroplaning. 
Hydroplaning  usually  happens  at  higher  speeds.  There  just isn’t  a  hard  and 
fast rule  about  hydroplaning.  The best advice is to  slow  down  when 
it is 
raining.

What You’//  Find  in  the  Index; 
A list of all PSP’s published  by GMC Truck in a model  year. PSP’s 
covering  all models  of GMC  light trucks are listed in the same  index. 
Ordering  information so you can buy  the specific  PSP’s  you may want. 
Price information  for the PSP’s you  may  want  to buy. 
How You Can  Get  an  Index: 
Indexes are published periodically. Most  of the PSP’s which  could 
potentially  apply to the most  recent GMC Truck models  will  be listed 
in the 
most recent publication  for that model  year. This means  you  may  want 
to 
wait until the end  of the model year before ordering  an index, if you  are 
interested 
in buying  PSP’s pertaining to a current  model year car  or  truck. 
Some 
PSP’s pertaining to a  particular  model  year  vehicle  may  be  published in 
later  years,  and  these  would  be  listed in the  later  year’s  index.  When  you  order 
an  index  for a model  year  that  is  not  over 
yet, we’ll  send  you  the  most  recently 
published  issue.  Check  the  ordering  form 
for indexes  for earlier  model  years. 
Cut  out the ordering  form, 
fill it out, and mail it in. We  will  then  see to it 
that  an index  is mailed to you.  There  is no  charge  for  indexes for the 
1939-1 994 model years. 
Toll-Free  Telephone  Number 
If you want  an additional ordering form for  an index or a subscription,  just 
call  toll-free  and we’ll  be  happy to send  you one. Automated recording 
equipment  will take your name and mailing address. The number  to call  is 
1-800-551-4123. 
Copies at Participating  Dealers 
Copies  of Indexes and individual PSP’s are  at your participating  GMC 
Truck  dealer. 
You can ask to see them. 
A Very  lmportant  Reminder 
These PSP’s are meant  for technicians.  They  are not meant for the 
“do-it-yourselfer”.  Technicians have the equipment, tools, safety 
instructions, and  know-how 
to do a job quickly  and safely. 
GMC  Truck reserves 
the right to  change these procedures  without notice 
after November,  1992.
