Filling Your Tank The cap. is behind  a hinged  door on the  left  side of 
your  vehicle. 
I 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. 
While refueling,  hang  the 
cap  inside the  fuel door. 
To take  off the  cap,  turn it  slowly  to  the  left 
(counterclockwise).

I 1 CAUTIOT’ 
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  Oldsmobile”  in  the  Index.  When  you  put  the 
cap back  on, 
turn it to  the  right  until 
you  hear  at  least  three  clicks. 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  retailer  can  get  one  for  you. If you  get 
the  wrong  type,  it  may  not  fit 
or have  proper 
venting,  and  your  fuel tank  and  emissions  system 
might  be damaged.

Checking Things Under  the  Hood Hood Release 
A CAUTION: 
I 
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. 
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. 
To open  the hood,  first 
pull  the handle inside 
the  vehicle. 
Then 
go to the  front  of  the 
vehicle  and release  the 
secondary  hood  release. 
Lift  the hood.

on properly. Then just  pull the hood down and close 
LOW OIL 
LEVEL 
,If the LOW  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 
“Low 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 after  you  get 
fuel.  In order to  get an accurate reading, the oil  must  be 
hot  and  the vehicle  must 
be on level  ground.

Turn  off  the engine and  give  the oil 20  minutes  to drain 
back  into the oil  pan.  If 
you don’t, the oil  dipstick  might 
not  show  the  actual  level.

Checking  Engine  Oil 
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 Oil 
If the  oil ist at  or  below  the  lower  mark,  then  you’ll  need 
to  add  some  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 
cross-hatched  area’that shows  the  proper 
operating  range,  your  engine  could  be  damaged.

What Kind of Oil to Use 
3.1L L82 Engine  3.4L LQ 1  Engine 
Just 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. 
be  sure  you  use  oil that  has 
the Starburst  symbol  on  the 
front 
of the  oil  container.  If 
for  you,  be  sure the oil put 
into  your  engine  is
