Parking  on Hills 
You really should  not park your vehicle, 
with  a  trailer attached,  on a hill.  If 
something goes wrong, your  rig  could 
start  to  move. People  can be injured, 
and  both  your vehicle  and  the trailer 
can  be damaged. 
But 
if you  ever have  to park  your  rig on 
a hill, here’s how  to  do  it: 
1. Apply your regular  brakes,  but don’t 
shift  into 
P (Park)  yet. 
2. Have someone place choclts  under 
the  trailer wheels. 
3. When  the wheel chocks  are in place, 
release  the regular  brakes until the 
chocks  absorb the load. 
apply your parking  brake,  and  then 
shift  to 
P (Park). 
4. Reapply  the regular brakes. Then 
5. Release  the regular brakes. 
When You Are  Ready to Leave 
Affer  Parking  on  a  Hill 
1. Apply  your regular brakes  and hold 
the  pedal  down  while 
you: 
Start your engine; 
Shift into  a  gear;  and 
Release  the parking brake. 
2. Let  up on  the  brake  pedal. 
3. Drive slowly  until the trailer  is clear 
4. Stop  and  have someone  pick up  and 
of 
the  chocks. 
store  the chocks. 
Maintenance  When  Trailer  Towing 
Your vehicle  will need service more 
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  quicltly. 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 with 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 
a real  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. 
See 
Scheduled  Maintenance  Services in 
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.

Automatic  Transaxle  Fluid 
When to 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 
if you 
have  been  driving: 
When  outside  temperatures  are  above 
At high speed for  quite  a while.

Inflation-Tire  Pressure 
The  CertificatiodTire label which  is on 
the  rear edge  of the  driver’s  door shows 
the  correct inflation  pressures for your 
tires,  when they’re cold. “Cold” means 
your  vehicle  has  been  sitting  for at least 
three  hours  or  driven  no more  than a mile. 
NOTICE: 
Don’t  let anyone  tell  you  that 
underinflation 
or overinflation  is  all 
right. It’s  not. If your tires  don’t 
have  enough  air  (underinflation) 
you  can get: 
Too  much  flexing 
Too much  heat 
Tire overloading 
Bad wear 
Bad  handling 
Bad  fuel  economy. 
If your tires  have too much air 
(overinflation)  you can get: 
Unusual wear 
Bad  handling 
Rough  ride 
Needless damage from road 
hazards. 
When to Check 
Check your tires  once  a month or more. 
Don’t forget your compact  spare tire. It 
should be  at 
60 psi (420 1tPa). 
How to Check 
Use a good  quality pocket-type  gage to 
check tire  pressure. Simply  loolting  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  Inspection  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 CertificationlTire label. 
Make  certain  that  all wheel  nuts  are 
properly tightened.  See 
Wheel Nut 
Toque in the Index.

Introduction 
A Word  About Maintenance 
We at General  Motors  want  to help  you 
keep  your  vehicle  in good  working 
condition.  But  we don’t lmow  exactly 
how  you’ll  drive  it. You  may  drive  very 
short  distances  only a few  times  a week. 
Or  you  may  drive long distances  all the 
time  in very  hot,  dusty  weather. 
You 
may use your  vehicle  in  malting 
deliveries.  Or 
you may  drive it to  work, 
to  do  errands  or  in  many other ways. 
Because  of all  the  different  ways  people 
use  their  GM vehicles,  maintenance 
needs  vary. 
You may  even  need  more 
frequent  checks and replacements  than 
you  will  find  in the  schedules  in  this 
part. 
So please  read  this  part  and  note 
how  you  drive.  If you  have  any 
questions  on  how  to keep your  vehicle 
in  good  condition,  see  your Oldsmobile 
dealer,  the  place  many  GM owners 
choose  to have  their  maintenance  work 
done.  Your dealer  can be relied  upon to 
use proper  parts  and practices. 
Your Vehicle  and  the Environment 
Proper  vehicle  maintenance  not  only 
helps  to keep your  vehicle in good 
working  condition,  but also helps  the 
environment.  All recommended 
maintenance  procedures  are  important.  Improper  vehicle maintenance  or  the 
removal  of important  components  can 
significantly  affect  the quality 
of the air 
we  breathe.  Improper  fluid  levels  or 
even  the wrong  tire inflation  can 
increase  the  level of emissions  from 
your  vehicle. 
To help protect  our 
environment,  and  to help  keep your 
vehicle  in good  condition,  please 
maintain  your vehicle  properly. 
How This Part is Organized 
The remainder  of this  part  is  divided 
into  five sections: 
Section 
A: Scheduled  Maintenance 
Services  shows what to have  done  and 
how  often.  Some of these  services  can 
be  complex, 
so unless  you are technically 
qualified  and have  the necessary 
equipment,  you should let your dealer’s 
service  department  or  another  qualified 
service  center do these  jobs.  If 
you  are skulled  enough  to do  some 
work  on your  vehicle,  you  will  probably 
want  to get  the  service  information  GM 
publishes.  You  will find a list  of 
publications  and how  to get  them  in 
this  manual.  See 
Service Publications 
in  the Index. 
Section B: Owner Checks  and Services 
tells  you  what should be checked 
whenever  you stop  for fuel.  It also 
explains  what you can easily  do to help 
keep your  vehicle in good  condition.

C: Periodic  Maintenance 
Inspections  explains important
