If Your Diesel Engine  Won’t  Start 
If you‘ve  run out of fuel,  look at  “Running  Out of Fuel”  (see “Diesel Fuel 
Requirements  and Fuel System” 
in the Index). 
If you‘re  not out  of fuel,  and  your engine won’t start, do this: 
Turn your ignition key to RUN.  Make  sure  that the GLOW  PLUGS  light is 
out. Then  IMMEDIATELY  turn the ignition key to START. 
If the light  doesn’t  go off, wait  a few  seconds,  then try starting your  engine 
again.  And, see your  dealer  as  soon as 
you can for  a  starting  system check. 
If the light  comes on and  then  goes off and you  know  your batteries  are 
charged,  but your engine still won’t  start, your vehicle needs  service. 
If the light does not come on when the engine  is cold,  your vehicle needs 
service. 
If  your batteries  don‘t have enough  charge to start  your  engine, see 
“Battery” 
in the Index. 
Be  sure  you have the right  oil for  your  engine,  and that you’ve changed the 
oil  at the  proper  times. If you  use the wrong 
oil, your  engine  may  be  harder 
to  start. 
If  the  engine  starts,  runs a  short  time,  then stops,  your vehicle  needs service.

NOTICE: 
If you keep driving  your  vehicle  with  this  light  on,  after  a while 
the  emission  controls 
won’t work  as  well,  your  fuel  economy 
won’t 
be as good,  and  your  engine  may  not  run  as smoothly. 
This  could  lead 
to costly  repairs  not  covered by your  warranty. 
Check  Gages  Light 
This  orange  light will come on briefly  when  you  are starting the engine. If 
the  light comes on and stays on while you are driving, it could indicate  a 
problem  with your  vehicle. 
It could be a problem  with your oil pressure. 
coolant  temperature,  or  some  other  problem.  Check  your various  gages 
to 
see if they are in the warning  zones. If they are, have your vehicle serviced 
right  away.

Oil Pressure Gage 
The oil pressure  gage  shows the engine oil pressure in psi (pounds  per 
square  inch)  when  the engine is running. Canadian  vehicles  indicate 
pressure 
in kPa (kilopascals). Oil pressure  may  vary with engine  speed, 
outside  temperature  and  oil viscosity,  but readings  above the 
low pressure 
zone indicate  the norn~al  opcrating  ranse. 
A reading in the low pressure zone may bc caused by a dangemusly  low oil 
level or  other  problem  causing low oil pressure.  Check  your oil as soon as 
possible. 
A CAUTION: 
Don’t keep  driving  if the  oil pressure is low. If you do, your 
engine  can  become 
so hot  that  it  catches  fire. You or others  could 
be  burned.  Check  your  oil 
as soon as possible and  have  your 
vehicle  serviced. 
NOTICE: 
Damage  to  your  engine  from  neglected  oil problems  can  be 
costly  and is not  covered  by your  warranty.

display an error  and eject  the cartridge.  This  is  normal  and is the  result  of  an 
added  feature 
in the tape  player  that  detects broken tapes. If an  e.rror  occurs, 
you 
will need  to insert the  cleaning  cassette  at least 3 times to thoroughly 
clean  the tape player. 
You  may  prefer  to  use 
a non-scrubbing  action, wet-type  cleaner. This type 
of  cleaner  uses 
a fabric belt to clean the tape head.  This type of cleaner 
cassette  will 
not cause an error, but it may not clean the tape player as 
thoroughly as the scrubbing  type cleaner. 
A scrubbing  action cleaner  cassette  is available  through your retailer (SPO 
# 12344600). 
Cassettes  are  subject to wear and the  sound quality  may degrade  over time. 
Always  verify that the  cassette tape is 
in good condition  and the tape player 
is  clean before  obtaining  service  on  your tape player. 
NOTICE: 
Cassette  tape  adapter  kits  for  portable CD players  will  not  work 
in  your  cassette  player.  These  adapters 
will cause  the  radio  to 
display  an  error  and  the  adapter  cassette 
will be  ejected. 
Care of Compact Discs 
Handle  discs  carefully. Store them in their original cases  or other  protective 
cases  and away  from  direct  sunlight and dust.  If the  surface 
of a disc is 
soiled, dampen 
a clean,  soft  cloth in a mild, neutral detergent  solution and 
clean 
it, wiping  from the center to the  edge. 
Be  sure  never  to touch the signal  surface when handling  discs. Pick up discs 
by  grasping  the outer  edges  or  the edge  of the hole and the  outer  edge. 
Fixed Mast  Antenna 
The fixed  mast  antenna  can  withstand  most  car washes without be.ing 
damaged. 
If the mast  should  ever  become slightly bent, you can straighten it 
out by hand.  If the mast is badly bent,  as it might  be  by vandals, you should 
rep1  ace  it. 
Check  every  once 
in a while  to be  sure the mast  is  still tightened to the 
fender.

When you want to leave  the freeway,  move to the  proper  lane  well  in 
advance.  If 
you miss your exit  do not,  under any  circumstances,  stop  and 
back  up. Drive  on 
to the next exit. 
The  exit ramp can  be curved,  sometimes  quite sharply. 
The 
exit speed is usually posted. 
Reduce  your speed according to your speedometer,  not to your sense 
of 
motion.  After driving  for any  distance  at higher  speeds,  you  may  tend to 
think  you are going  slower than you actually  are. 
Before  Leaving  on a Long  Trip 
Make sure you’re  ready.  Try to be well rested. If  you must start when  you’re 
not  fresh 
- such as after a day’s work - don’t  plan to make  too many 
miles that  first part 
of the journey.  Wear comfortable  clothing  and shoes  you 
can  easily drive 
in. 
Is your  vehicle ready for a long trip‘? If you keep it serviced  and maintained, 
it’s ready  to go. 
If it needs  service,  have it done before starting  out. Of 
course,  you’ll find experienced and able service  experts 
in GM dealers all 
across North America. They’ll be ready  and willing to help if you need it.

Windshield Washer Fluid: Is the reservoir  full? Are all windows  clean

FueZ,  Engine  Oil,  Other  Fluids: Have you checked all levels? 
Lamps: Are they all working? Are the lenses  clean? 
Tires: They are vitally important to  a  safe, trouble-free  trip. Is the tread 
good enough  for long-distance  driving? Are 
the tires all inflated to the 
recommended  pressure? 
Weather Forecasts: What’s the weather  outlook along your  route? 
Should 
you delay your trip a short time to avoid  a major  storm  system? 
Maps: Do you have  up-to-date  maps? 
Highway  Hypnosis 
Is there  actually  such a condition as “highway hypnosis”?  Or  is  it just  plain 
falling  asleep  at the wheel? Call it highway  hypnosis, lack  of awareness,  or 
whatever. 
There 
is something  about an easy stretch  of road  with  the  same scenery, 
along  with the 
hum of the tires  on the road, the  drone of the engine,  and the 
rush 
of the wind against the vehicle that can make  you sleepy. Don’t  let  it 
happen 
to you! If it does,  your vehicle can leave the road  in less than a 
second, and  you could crash and  be injured.

When You Are  Ready to Leave  After  Parking  on a Hill 
1. Apply  your  regular  brakes and hold  the pedal down  while you: 
Start  your  engine: 
Shift  into a  gear;  and 
Release  the  parking  brake. 
2. Let up on the brake  pedal. 
3. Drive slowly until the trailer is clear  of the  chocks. 
4. Stop  and have  someone pick up and store  the chocks. 
Maintenance  When  Trailer  Towing 
Your  vehicle will need service more often  when you’re  pulling a trailer. See 
the  Maintenance  Schedule 
for more on this.  Things that are especially 
important 
in trailer  operation  are  automatic transmission  fluid  (don’t 
overfill),  engine  oil,  axle lubricant,  belt, cooling  system,  and brake 
adjustment.  Each  of these  is covered 
in this manual, and the Index will  help 
you  find them quickly.  If you’re trailering,  it’s 
a good idea to review  these 
sections  before you start your  trip. 
Check  periodically  to  see that all  hitch 
nuts and bolts  are tight.

Fuel  Requirements 
NOTICE: 
Diesel fuel  or  fuel  additives  not  recommended  in  this  manual 
could  damage  your  fuel  system  and  engine.  Your warranty 
wouldn’t  cover  this  damage.  And: 
Diesel  fuel  that  has  been  mixed  with  engine  oil could  damage 
your  engine  and  emission  controls.  Always  check  with  your 
service  station  operator  to  make  sure  his  diesel  fuel  has  not \
been  mixed  with  engine  oil. 
If you  ever  run  out of diesel  fuel,  it  can  be  difficult  to  restart 
your  engine.  “Running  Out  of Fuel,”  later  in this  section,  tells 
you  how  to  get  it  started  again. 
To avoid all this, try  never  to 
let  your  tank  get  empty. 
What Fuel  to Use 
For  best results,  use Number 2-D diesel fuel  year-round  (above and below 
freezing  conditionsj  as  oil companies  blend Number 
2-D fuel to address 
climate  differences. Number 
1-D diesel fuel  may  be  used in very cold 
temperatures  (when 
it stays  below 0°F or -18°C);  however, it will produce 
a power and fuel economy loss. The  use of Number I-D diesel fuel in warm 
or hot  climates  may result in stalling, poor  starting  when the engine  is hot 
and 
may damage  the fuel injection system. 
Diesel  fuel may  foam when  you 
fill your tank.  This  can cause the  automatic 
pump  nozzle to shut  off, even though your tank isn’t 
full. If this happens, 
just  wait  for the  foaming  to stop  and then  continue  to 
fill your tank. 
A CAUTION: 
Heat  coming  from  the  engine  may  cause  the  fuel  to  expand  and \
force  the  fuel  out  of your  tank. 
If something  ignites  the  fuel, a 
fire could  start  and  people  could  be  burned. To help  avoid  this, 
fill  your  fuel  tank  only  until  the  automatic  nozzle shuts 
off. 
Don’t try  to  “top  it off.”

Fuels  in  Foreign  Countries  (Gasoline Engines) 
If you plan on driving in another  country  outside the U.S. or  Canada, 
unleaded  fuel  may  be hard to find. 
Do not use leaded  gasoline. If you  use 
even  one  tankful,  your emission controls won’t work well  or at all.  With 
continuous  use, spark plugs  can get fouled,  the exhaust  system can  corrode, 
and your  engine 
oil can deteriorate  quickly. Your vehicle’s oxygen  sensor 
will  be  damaged. 
All of that means costly  repairs  that wouldn’t  be covered 
by  your warranty. 
To check  on fuel availability,  ask an auto  club,  or contact a major oil 
company  that  does business in the country  where you’ll be  driving. 
You  can also  write 
us at the following  address for advice.  Just  tell us where 
you’re  going and  give your  Vehicle  Identification  Number 
(VIN).

Filling Your Tank 
The  fuel cap is behind 
a  hinged  door on 
the 
left side  of your 
vehicle. 
A CAUTION: 
Gasoline  vapor is highly  flammable.  It burns  violently,  and  that 
can  cause  very  bad  injuries.  Don’t  smoke 
if you’re  near  gasoline 
or refueling  your  vehicle.  Keep  sparks,  flames,  and  smoking 
materials  away  from  gasoline.
