Your  dealer knows your  vehicle  best  and wants you to 
be  happy  with  it.  We hope  you’ll 
go to your  dealer for 
all  your  service  needs.  You’ll  get genuine GM  parts  and 
GM-trained  and  supported  service people. 
We  hope  you’ll  want  to keep your GM  vehicle  all GM. 
Genuine 
GM parts  have  one of these  marks:

Doing  Your Own Service  Work 
If  you want to do some of  your  own service  work,  you’ll 
want  to use  the  proper 
GM Service  Manual. It tells  you 
much  more  about  how 
to service  your  vehicle  than  this 
manual  can. 
To order the  proper  service manual,  see 
“Service  and  Owner Publications”  in  the Index. 
Your  vehicle  has  an  air bag  system.  Before  attempting  to 
do  your  own service  work, see “Servicing  Your Air 
Bag-Equipped  Vehicle”  in  the  Index. 
You  should  keep a  record  with  all  parts  receipts  and  list 
the  mileage  and  the  date 
of any service  work  you 
perform.  See “Maintenance  Record”  in the  Index.

You can be injured and J licle  could  be 
damaged  if  you 
try to do  service  work  on  a 
vehicle  without  knowing  enough  about it. 
! 0 Be sure  you have  sufficient  knowledge, 
I 
experience,  the proper replacement  parts 
and  tools  before  you attempt  any  vehicle 
maintenance  task. 
Be  sure  to  use the proper  nuts,  bolts  and 
other  fasteners.  “English”  and “metric” 
fasteners can  be  easily  confused. 
If you  use 
the  wrong  fasteners, parts can later  break 
or  fall 
off. You  could  be  hurt. 
Adding Equipment to the Outside of 
Your Vehicle 
Things  you might  add to the  outside  of your vehicle  can 
affect  the  airflow  around 
it. This may cause  wind noise 
and affect windshield washer  performance. Check with 
your  dealer  before  adding equipment  to the  outside  of 
your vehicle.  Use 
regular  unleaded  gasoline rated at 87  octane  or 
higher.  At  a minimum,  it should  meet specifications 
ASTM  D48  14 in the  United States and  CGSB 3.5-M93 
in  Canada.  Improved gasoline specifications  haw been 
developed  by the  American  Automobile  Manufacturers 
Association (AAMA)  for better vehicle performance 
and  engine  protection. Gasolines meeting  the AAMA 
specification could provide improved driveability and 
emission  control  system protection  compared 
to 
other gasolines. 
Be  sure  the posted  octane is at least  87. 
If the octane  is 
less than  87, you  may  get a heavy  knocking noise  when 
you  drive. 
If it’s  bad  enough,  it can damage your engine. 
If  you’re using fuel  rated at 
87 octane  or  higher and  you 
hear  heavy  knocking, your  engine needs service. But 
don’t  worry  if  you hear a little pinging noise  when 
you’re  accelerating  or driving  up a 
hill. That’s normal, 
and  you  don’t have  to  buy a higher  octane fuel to get rid 
of  pinging.  It’s the heavy,  constant  knock that means 
you  have  a problem.

Downloaded from www.Manualslib.com manuals search engine If your  vehicle  is certified  to meet  California  Emission 
Standards  (indicated  on the  underhood  emission  control 
label),  it is  designed  to operate  on fuels  that  meet 
California  specifications. 
If such  fuels are  not  available 
in  states  adopting  California emissions  standards,  your 
vehicle  will operate  satisfactorily  on fuels  meeting 
federal  specifications,  but emission control system 
performance  may  be  affected.  The malfunction  indicator 
lamp on  your  instrument  panel  may  turn 
on and/or your 
vehicle  may  fail a smog-check  test. If this  occurs,  return 
to  your  authorized 
GM dealer  for diagnosis to determine 
the cause  of  failure.  In  the event it 
is determined  that  the 
cause 
of the  condition  is the  type  of  fuels used,  repairs 
may  not  be  covered by your  warranty. 
Some  gasolines  that 
are not  reformulated  for low 
emissions contain  an octane-enhancing  additive  called 
methylcyclopentadienyl  manganese tricarbonyl  (MMT); 
ask  your  service  station operator  whether or not  his  fuel 
contains  MMT. General Motors does  not  recommend  the 
use 
of such  gasolines.  If fuels  containing MMT  are used, 
spark  plug  life may  be  reduced  and your  emission 
control system  performance  may  be  affected.  The 
malfunction  indicator  lamp on your  instrument  panel 
may  turn 
on. If  this  occurs,  return  to your  authorized 
GM  dealer  for service.  To  provide  cleaner  air,  all 
gasolines in the  United  States 
are  now  required  to contain additives  that  will  help 
prevent  deposits  from forming in your  engine and fuel 
system,  allowing  your  emission  control  system 
to 
function  properly.  Therefore, you  should  not  have  to add 
anything 
to the  fuel. In addition,  gasolines  containing 
oxygenates,  such  as ethers  and ethanol,  and 
reformulated  gasolines  may  be  available 
in your  area to 
help  clean  the  air.  General Motors  recommends  that 
you 
use these gasolines  if  they comply  with  the 
specifications  described  earlier. 
NOTICE: 
Your  vehicle  was  not  designed  for  fuel  that 
contains  methanol.  Don’t  use  it.  It  can  corrode 
metal  parts  in  your  fuel  system  and  also  damage 
plastic  and  rubber  parts.  That  damage  wouldn’t 
be  covered  under  your  warranty.

If you  plan  on driving  in another country outside the 
United  States or Canada,  the proper fuel  may  be  hard  to 
find.  Never  use  leaded  gasoline or any  other  fuel  not 
recommended  in  the  previous  text  on  fuel.  Costly  repairs 
caused  by 
use of improper fuel 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

Filling  Your  Tank 
A CAUTION: 
-- 
Gasoline  vapor  is highly  flaml,,~ble.  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.

Downloaded from www.Manualslib.com manuals search engine The fuel  cap is  behind  a  hinged  door on the  driver’s  side 
of  your  vehicle. 
While  refueling,  place  the cap  in  the holder  on the  fuel 
filler  door. 
To remove the cap,  turn it slowly  to the left 
(counterclockwise).  The cap has  a spring  in it; 
if you  let 
go  of  the  cap too soon, 
it will  spring  back to  the  right.

A CAUTION: 
If you get  gasoline  on  yourself  and  then 
something  ignites  it,  you could  be  badly  burned. 
Gasoline  can  spray  out  on  you if you  open  the 
fuel  filler  cap  too  quickly. This  spray  can  happen 
if  your  tank  is nearly  full, and is more  likely  in 
hot  weather.  Open  the  fuel  filler  cap  slowly and 
wait  for  any  (‘hiss”  noise to  stop.  Then  unscrew 
the  cap  all  the  way. 
Be  careful  not  to spill  gasoline.  Clean gasoline  from 
painted  surfaces  as  soon  as  possible.  See “Cleaning  the 
Outside  of  Your  Vehicle”  in  the  Index. 
When  you  put  the  cap back  on,  turn  it to  the  right 
(clockwise)  until  you  hear  a  clicking  sound.  Make  sure 
you  fully  install  the cap. The diagnostic  system  can 
determine 
if the  fuel  cap has  been  left off or improperly 
installed.  This would  allow  fuel to evaporate  into the 
atmosphere.  See “Malfunction  Indicator  Lamp”  in 
the  Index.

NOTICE: 
If you need  a  new  cap,  be  sure  to  get  the  right 
type.  Your  dealer  can  get  one  for  you. 
If you  get 
the  wrong  type,  it  may  not  fit  properly.  This  may  cause  your  malfunction  indicator  lamp  to  light  and  your  fuel  tank  and  emissions  system  may  be 
damaged.  See “Malfunction  Indicator  Lamp”  in 
the  Index. 
Filling a Portable  Fuel Container 
A CAUTION: 
Never  fill  a  portable  fuel  container  while it is in 
your  vehicle.  Static  electricity  discharge  from  the 
container  can  ignite  the  gasoline  vapor. 
You can 
be  badly  burned  and  your  vehicle damaged  if this 
occurs. 
To help  avoid  injury to you  and  others: 
Dispense  gasoline  only  into 
approved  containers. 
CAUTION:  (Continued)

Do not fill a  container  whilc : is inside a 
vehicle,  in  a vehicle’s  trunk,  pickup  bed  or 
on  any  surface  other  than  the  ground.

Checking Things Under  the Hood 
A CAUTION: I 
Things  that  burn  can  get  on hot  engine  parts  and 
start  a  fire.  These  include  liquids  like  gasoline, 
oil,  coolant,  brake fluid,  windshield  washer  and 
other  fluids,  and  plastic 
or rubber. You or  others 
could  be  burned.  Be careful  not  to  drop  or  spill 
things  that  will burn  onto  a  hot  engine.
