These  grades  are molded on the  sidewalls  of passenger 
car  tires. 
While  the  tires  available 
as standard  or optional 
equipment 
on General  Motors  vehicles may  vary  with 
respect  to these  grades,  all such  tires meet  General 
Motors  performance  standards  and have  been approved 
for  use 
on General  Motors  vehicles. All passenger  type 
(P Metric)  tires must  conform to Federal safety 
requirements 
in addition  to  these  grades. 
Wheel  Alignment  and  Tire  Balance 
The wheels on your  vehicle  were  aligned  and balanced 
carefully  at the  factory  to  give  you the longest  tire  life 
and best overall  performance. 
In  most  cases, 
you will not need to have your wheels 
aligned  again. However, 
if you notice  unusual  tire wear 
or  your  vehicle  pulling  one  way 
or the other, the 
alignment  may need to  be reset. 
If you  notice  your 
vehicle  vibrating  when  driving  on 
a smooth road, your 
wheels  may need  to be  rebalanced. 
Wheel  Replacement 
Replace  any wheel  that  is bent,  cracked,  or  badly rusted 
or  corroded. 
If wheel nuts  keep  coming  loose,  the  wheel, 
wheel  bolts, and wheel nuts should  be replaced. 
If the 
wheel  leaks air, replace  it  (except  some  aluminum 
wheels, which  can  sometimes  be  repaired).  See your 
Oldsmobile  retailer 
if any  of these  conditions  exist. 
Your  retailer  will know the kind  of wheel  you need. 
Each  new wheel  should have 
the same  load  carrying 
capacity, diameter, width, offset, and  be mounted  the 
same  way 
as the one it replaces. 
If you  need  to  replace  any of your  wheels,  wheel bolts, 
or  wheel  nuts,  replace  them only with  new GM original 
equipment  parts.  This  way, 
you will be  sure  to  have  the 
right  wheel, wheel bolts, and wheel nuts  for  your 
Oldsmobile  model.

Used  Replacement  Wheels 
NOTICE: 
The  wrong  wheel  can  also  cause  problems  with 
bearing  life,  brake  cooling, 
speedometer/odometer  calibration,  headlamp  aim,  bumper  height,  vehicle  ground  clearance, 
and  tire  or  tire  chain  clearance  to the 
body and

Tire Chains 
NOTICE: 
If your Oldsmobile  has P195/65R15 or 
P205/55R16 size tires, don’t  use tire  chains;  they 
can  damage your  vehicle. 
If you  have other tires, use tire  chains  only  where 
legal  and only  when  you  must.  Use  only 
SAE 
Class “S” type  chains  that  are  the  proper  size for 
your  tires.  Install  them  on  the front  tires and 
tighten them 
as tightly  as possible  with  the ends 
securely  fastened.  Drive  slowly  and follow  the 
chain manufacturer’s instructions.  If  you can 
hear  the chains contacting your  vehicle, stop  and 
retighten  them. 
If the contact  continues,  slow 
down  until 
it stops.  Driving too fast or spinning 
the  wheels  with  chains on  will  damage your 
vehicle. 
Appearance  Care 
Remember,  cleaning  products  can  be  hazardous.  Some  are  toxic.  Others  can  burst  into flame  if  you  strike  a 
match  or  get  them  on  a  hot 
part of the  vehicle.  Some are 
dangerous if  you breathe  their  fumes  in a closed  space. 
When  you  use  anything  from  a  container  to clean  your 
Oldsmobile,  be  sure  to  follow  the  manufacturer’s  warnings  and  instructions.  And  always  open  your  doors 
or  windows  when  you’re  cleaning  the  inside. 
Never use  these  to  clean  your  vehicle: 
0 Gasoline 
Benzene 
Naphtha 
0 Carbon  Tetrachloride 
0 Acetone 
0 Paint  Thinner 
Turpentine 
0 Lacquer  Thinner 
0 Nail  Polish  Remover 
They  can 
all be  hazardous -- some  more  than  others -- and 
they  can  all  damage  your  vehicle,  too.

Using Solvent-Type Cleaner on Fabric 
First,  see if you have to use  solvent-type  cleaner  at  all. 
Some 
spots and  stains will clean  off better  with  just 
water 
and mild soap. 
If you need to LIS~ a solvent: 
0 Gently  scrape  excess  soil  from  the  trim  material  with 
a clean, dull knife  or scraper.  Use  very little  cleaner, 
light  pressure 
and clean  cloths  (preferably 
cheesecloth).  Cleaning  should  start 
at the  outside of 
the stain, "feathering"  toward the center.  Keep 
changing 
to a clean  section of the  cloth. 
0 When you clean a stain  from  fabric,  immediately  dry 
the  area 
with a blow  dryer to help  prevent a cleaning 
ring.  (See the previous 
NOTICE.)

Cleaning  the  Outside of Your 
Oldsmobile 
The  paint  finish  on your vehicle provides  beauty, depth 
of  color, gloss retention  and durability. 
Washing Your Vehicle 
The  best  way  to  preserve  your  vehicle’s finish is to  keep 
it  clean  by washing it  often with lukewarm  or cold 
water. 
Don’t  wash your vehicle in  the  direct rays of the  sun. 
Don’t  use strong  soaps or chemical detergents. Use 
liquid hand, dish  or  car washing  (mild detergent) soaps. 
Don’t use cleaning agents that are petroleum based,  or 
that  contain  acid or abrasives.  All cleaning agents 
should be  flushed promptly  and 
not allowed to dry on 
the  surface,  or they could  stain. Dry the finish  with 
a 
soft,  clean  chamois  or a 100% cotton towel to avoid 
surface  scratches and water spotting. 
High pressure vehicle washes may  cause water to  enter 
your vehicle. 
Finish  Care 
Occasional waxing  or mild  polishing  of your 
Oldsmobile 
by hand  may be necessary to remove 
residue  from  the  paint finish.  You can get 
GM approved 
cleaning products  from your retailer.  (See “Appearance 
Care  and Materials” 
in the Index.) 
Your  Oldsmobile 
has a “basecoatlclearcoat” paint  finish. 
The  clearcoat gives more depth  and  gloss  to the colored 
basecoat. Always  use waxes  and polishes that are 
non-abrasive  and made  for 
a basecoatklearcoat paint 
finish. 
I NOTICE: 
Machine  compounding  or  aggressive  polishing  on 
a  basecoat/clearcoat  paint  finish may  dull  the 
finish 
or leave  swirl  marks. 
Foreign materials such as calcium chloride and other  salts,  ice melting agents, road oil and  tar, tree  sap,  bird 
droppings,  chemicals  from industrial chimneys,  etc. can 
damage  your vehicle’s  finish if they  remain  on painted 
surfaces.  Wash the vehicle  as 
soon as possible. If 
necessary, 
use non-abrasive  cleaners  that are marked 
safe 
for painted surfaces to remove  foreign matter.
