Let  only  qualified technicians work 
on  your  air bag  system.  Improper 
service  can mean  that your  air bag 
system  won’t  work properly.  See  your 
dealer  for  service. 
NOTICE: 
If  you  damage  the cover  for  the 
driver’s  air bag,  it may  not work 
properly.  You  may  have to replace 
the  air bag  on  the  steering wheel. 
Do not open or break  the air bag 
cover. 
Is the smoke from an air bag  inflation 
harmful? 
The  particles  emitted during air  bag 
inflation  are not harmful  to most 
people.  Some  people  with respiratory 
ailments  may experience  difficulty 
breathing 
if they  stay  in the  vehicle  with 
the  windows  closed  after  air bag 
inflation. 
So, if  your  air bag  inflates,  you 
and  any  passengers  should exit the 
vehicle 
if and  when  it  is  safe  to do so. If 
you  or your  passengers  can’t get out  of 
the  vehicle,  try to get  fresh  air by 
opening  a window,  turning on  the  fan, 
or  opening  a door. 
Servicing Your Air Bag-Equipped 
Oldsmobile 
The air  bag  affects  how  your 
Oldsmobile  should be  serviced.  There 
are parts  of the  air bag  system  in several 
places  around  your  vehicle. 
You don’t 
want  the system  to inflate  while 
someone  is working  on your  vehicle. 
Your  Oldsmobile  dealer  and the 
1994 
Cutlass Supreme  Service  Manual  have 
information  about servicing  your 
vehicle  and the air bag  system.  The air 
bag  system  does  not need  regular 
maintenance.

Mainfenance When  Trailer  Towing 
Your  vehicle  will  need  service  :nore 
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 transaxle  fluid (don’t 
overfill),  engine  oil,  belts, 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.

What to Do wifh Used Oil 
Did  you  know that used engine oil 
contains  certain  elements that may  be 
unhealthy  for  your skin  and  could even 
cause cancer?  Don’t let used  oil stay  on 
your  skin for  very  long.  Clean  your  skin 
and  nails  with  soap  and  water,  or a 
good  hand  cleaner.  Wash or properly 
throw  away clothing  or  rags containing 
used  engine oil..  (See  the manufacturer’s 
warnings  about  the  use and  disposal  of 
oil  products.) 
Used  oil  can be areal  threat  to  the 
environment.  If you  change  your  own 
oil,  be sure  to drain  all  free-flowing  oil 
from  the filter  before  disposal. Don’t 
ever  dispose  of oil  by  putting  it in  the 
trash,  pouring it  on the  ground,  into 
sewers,  or into  streams  or bodies  of 
water.  Instead,  recycle it by  taking  it  to 
a  place  that collects  used  oil. If you 
have  a problem  properly  disposing of 
your  used  oil, ask  your  dealer,  a service 
station  or a local  recycling  center for 
help. 
Air Cleaner 
Refer  to  the  Maintenance  Schedule to 
determine when  to replace  the  air filter 
and  the  crankcase  ventilation  filter. 
See 
Scheduled  Maintenance  Services i3 
the 
Index. 
NOTICE: 
If  the  air cleaner  is off, a backfire 
can  cause a  damaging  engine  fire. 
And,  dirt  can easily  get  into your 
engine, which  will  damage 
it. 
Always  have the air cleaner  in  place 
when  you’re  driving. 
To Check or Replace  the Air Filter: 
1. Remove  the four  screws  and pull  off 
the  cover.

2. Remove the air cleaner  filter. 
3. Be sure  to  install the air cleaner  filter 
and  replace  the cover  tightly. 
Automatic Transaxk Fluid 
When fo Check  and  Change 
A good  time  to check  your  automatic 
transaxle  fluid  level  is  when  the engine 
oil is changed.  Refer to the Maintenance 
Schedule  to determine when  to change 
your  fluid.  See 
Scheduled  Maintenance 
Services 
in  the Index. 
How to Check 
Because  this operation  can  be a little 
difficult,  you  may  choose  to have  this 
done  at  an  Oldsmobile  dealership 
Service  Department. 
If you do  it  yourself,  be sure  to  follow 
all  the  instructions here, or 
you could 
get 
a false  reading  on  the dipstick. 
NOTICE: 
Too much  or too.little  fluid can 
damage  your  transaxle. 
Too much 
can  mean  that some  of the  fluid 
could  come  out and  fall 
on hot 
engine  parts 
or exhaust  system, 
starting  a 
fire. Be sure  to  get an 
accurate  reading if you check  your 
transaxle  fluid. 
Wait  at least 
30 minutes  before 
checking  the  transaxle  fluid  level

While  pulling  a trailer. 
To get  the  right  reading,  the fluid 
should  be at 
normal operating 
temperature,  which  is  18O"F-to

(82°C to 93T).

How To  Check  Power  Steering 
When  you  replace  your  radiator  premre 
cap,  an 
AC@ cap is recommended. 
Thermostat 
Engine  coolant temperature  is 
controlled  by a thermostat in  the engine 
coolant  system. The thermostat  stops 
the  flow  of coolant through  the radiator 
until  the coolant  reaches  a preset 
temperature. 
When  you replace  your  thermostat, an 
AC@ thermostat is  recommended. 
Fluid 
- 
Unscrew the cap and  wipe the dipstick 
with a  clean  rag.  Replace  the cap  and 
completely  tighten it. Then  remove the 
cap  again  and look  at  the  fluid  level  on 
the  dipstick. 
When  the engine  compartment  is hot, 
the  level  should  be at the 
H mark. 
When  the engine compartment is 
cool,  the level  'should  be  at  the 
C 
mark. 
What to Add 
Refer to  the  Maintenance  Schedule to 
determine what  kind of fluid  to use.  See

How to Check 
Use a  good  quality  pocket-type  gage  to 
check  tire pressure.  Simply  looking  at 
the  tires  will not tell  you  the pressure, 
especially  if you  have  radial tires 
- 
which may look  properly  inflated  even if 
they’re  underinflated. 
If your tires have  valve caps, be sure  to 
put  them  back on. They  help prevent 
leaks  by keeping  out dirt and moisture. 
~ 
Tire  lnspection  and  Rotation 
To make  your  tires last longer,  have 
them inspected  and rotated  at the 
mileages  recommended  in  the 
Maintenance  Schedule. 
See Scheduled 
Maintenance  Services 
in  the Index. 
Use  this rotation pattern. 
After  the tires  have  been  rotated, adjust 
the  front and rear  inflation pressure  as 
shown 
on the  Tire-Loading  Information 
label.  Make  certain that all  wheel  nuts 
are  properly  tightened. See 
Wheel Nut 
Torque in the Index.
