/1 CAUTION: 
You can be injured  and  your  vehicle  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, 
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. 
Fuel 
The  8th  digit  of your  vehicle  identification  number 
(VIN)  shows  the  code  letter  for your  engine.  You will 
find  the  VIN  at  the  top  left 
of your  instrument  panel. 
(See  .“Vehicle  Identification  Number” 
in the  Index.) 
If you  have  the 3800 engine (VIN Code K), use  regular 
unleaded gasoline  rated at 87 octane  or  higher. If you’re 
using  fuel  rated  at the  recommended  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. 
6-3  
     
        
        Page 255 of 395

If you  have  the 3800 Supercharged  engine (VIN Code 
l), use  premium  unleaded  gasoline  rated  at 91 octane 
or  higher.  With  the 
3800 Supercharged  engine,  in an 
emergency,  you  may  be  able  to  use  a  lower  octane -- as 
low  as 
87 -- if heavy  knocking  does  not  occur. If you 
are  using 
91 or  higher  octane  unleaded  gasoline  and 
you  hear  heavy  knocking,  your  engine  needs  service. 
At  a  minimum,  the  gasoline  you  use  should  meet  specifications 
ASTM D4814 in the  United  States  and 
CGSB 3.5-M93 in  Canada.  Improved  gasoline 
specifications  have  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  for  premium  is at  least 
91 (at 
least 
89 for  middle  grade  and 87 for  regular). 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 your  vehicle  is certified  to  meet  California  Emission 
Standards  (indicated 
on the  underhood  emission  control 
label),  it is designed  to operate  on  fwels  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  Pontiac  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 
Pontiac  dealer  for  service.

        Page 256 of 395

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 he1 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. 
Fuels  in  Foreign  Countries 
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 
Vehicle  Identification  Number 
(VIN).

Filling a Portable Fuel Container 
I 
1 A CAUTION: I 
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. 
Do not  fill a container  while it is  inside  a 
vehicle,  in  a vehicle’s  trunk, pickup  bed or 
on any  surface  other than the  ground.

Don’t  smoke  while  pumping  gasoline. 
Checking  Things  Under the Hood 
The  following  sections  tell you how  to  check fluids, 
lubricants  and  important  underhood parts. 
A CAUTION: 
I 
An electric  fan  under  the  hood  can start up  and 
injure  you  even  when  the  engine 
is not running. 
Keep  hands,  clothing  and tools  away from any 
underhood  electric  fan. 
A CAUTION: 
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.

Supercharged  Engine (If Equipped) 
Your  vehicle  may  have a 3800 Supercharged  engine. 
The  supercharger  is a  device  designed  to  pump  more  air 
into  the  engine  than  it  would  normally  use. 
This air, 
mixed  with  fuel,  creates  increased  engine  power.  Since 
the  supercharger  is a  pump  and  is  driven  from  an  engine 
accessory  drive  belt,  increased  pressure  is available  at 
all  driving  conditions. 
The  Powertrain  Control  Module  (PCM),  works  with  a  vacuum  control  to regulate  the  increased  pressure 
required  during  specific  driving  conditions.  When  this 
increased  pressure  or  boost  is not  desired,  such 
as during 
idling  and  light  throttle  cruising,  the  excess 
air that  the 
supercharger  is pumping  is  routed  through 
a bypass. 
All of these controls, working together, provide high 
performance  character  and  fuel  efficiency  in  the 
3800 V6 Supercharged  engine. 
Engine  Oil 
CHECK OIL 
LEVEL 
If the  CHECK OIL LEVEL 
light  on  the  instrument  panel 
comes 
on, it  means  you need 
to  check  your  engine oil level 
right  away. 
For more 
information, 
see “Check Oil 
Level Light” in the  Index.  You 
should  check  your  engine  oil  level  regularly; 
this is 
an  added  reminder. 
It’s 
a good  idea  to check  your  engine  oil  every  time  you 
get  fuel. 
In order  to  get an accurate  reading,  the  oil  must 
be  warm  and  the  vehicle  must  be  on  level  ground. 
Turn 
off the  engine  and  give  the  oil  a  few  minutes  to 
drain  back  into  the  oil  pan.  If  you  don’t,  the  oil  dipstic\
k 
might  not  show 
the actual  level.
