knock  that  means  you  have  a  problem. 
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 andor  your 
vehicle  may 
fail a  smog-check  test. If this  occurs,  return 
to  your  authorized  Cadillac  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 
Cadillac  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

Filling  Your  Tank 
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.

Downloaded from www.Manualslib.com manuals search engine 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  L‘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.

I 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

- 
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, 
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.

Things  that  burn  can  get on  hot  engine  parts  and 
start a fire.  These  include  liquids  like  gasoline,

fluid, windshield  washer  and 
other 
fluids, and  plastic  or rubber. You or  others 
could  be burned.  Be careful  not  to  drop  or spill

A CHECK OIL LEVEL message  will  appear  when  the 
engine oil  is approximately 
1 quart (1 L) low. If the 
' message  is displayed,  check  the  dipstick  level  and-add 
oil as needed. 
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. 
The  engine 
oil dipstick  is 
located  behind  the  radiator 
on  the  driver's  side of the 
engine.  The black  handle 
'says 
ENGINE OIL on  it. 
Turn off the  engine  .and 
give  the

Pull  out  the  dipstick  and  clean it with  a paper  towel or 
cloth,  then  push  it  back  in  all  the  way.  Remove  it  again, 
keeping  the  tip  down,  and  check  the  level. 
When to Add Engine  Oil 
If  the  oil is at  or  below  the ADD line,  then  you’ll  need 
to  add  at  least  one  quart  of oil.  But  you  must  use  the 
right  kind.  This  part  explains  what  kind 
of oil  to  use.  For 
crankcase  capacity,  see  “Capacities  and  Specifications” 
in the  Index. 
I NOTICE: 
Don’t  add  too  much  oil. If your  engine  has so 
much  oil  that  the  oil  level  gets  above  the  upper 
mark  that  shows  the  proper  operating  range, 
your  engine  could  be  damaged. 
The oil fill cap  is located 
behind  the  radiator  on  the 
passenger’s  side  of the 
engine. 
Turn the  cap  to  the 
left  to  remove  it. 
Be  sure  to  fill 
it enough  to  put  the  level  somewhere  in 
the  proper  operating  range.  Push  the  dipstick  all  the  way 
back  in  when  you’re  through.

Oils recommended  for your  vehicle  can  be  identified  by 
looking  for the “Starburst”  symbol.  This  symbol 
indicates  that  the oil has  been  certified  by  the American 
Petroleum  Institute 
(API). Do not  use  any oil which 
does  not  carry  this  Starburst  symbol. 
If  you change  your  own 
oil,  be  sure  you  use  oil 
that  has  the Starburst 
symbol  on  the front of the 
oil  container.  If  you  have 
your  oil changed 
for you, 
be  sure  the  oil  put  into 
your  engine 
is American 
Petroleum  Institute certified 
for  gasoline  engines. 
You should also use the  proper  viscosity oil for your 
vehicle,
